This is all in a package shorter than a Porsche 718 Cayman.
The Gordon Murray Automotive T.50 is finally here, and the famed automotive engineer's latest creation is quite a machine. It weighs a mere 986 kilograms (2,174 pounds) while packing a naturally aspirated 4.0-litre V12 making 654 bhp (488 kilowatts) and 344 pound-feet (467 Newton-metres) of torque. As if these numbers aren't impressive enough, there's a fan at the back sucking the vehicle to the road.
From the front, it's hard not to see the resemblance to the McLaren F1 – another Gordon Murray project. Both models share a low-slung nose with smooth styling and narrow inlets in the corners. An expansive, rounded windscreen, large windows in the doors, and clear panels in the roof create an airy greenhouse. A subtle scoop in the roof directs air to the V12, and the clear portions of the gullwing-opening rear panel offer just a peek at the inboard suspension.

Both the chassis and body are carbon fibre, and the components are incredibly lightweight. Gordon Murray Automotive claims the monocoque and exterior panels weigh less than 150 kilograms (331 pounds).
The 400-millimetre (15.75-inch) rear-mounted fan is among the T.50's most fascinating features. The piece spins at up to 7,000 rpm and runs on a 48-volt electric motor. It works with the active rear spoilers and diffusers to increase downforce by 50 percent in normal driving or by 100 percent in its Braking mode. The system also functions as ram-air induction for the engine to increase the powerplant's output by around 49 bhp (37 kW).
It's worth noting T.50's performance and tech comes in a compact footprint. At 4,352 mm (171.34 in) long, the vehicle is just over an inch shorter than a Porsche 718 Cayman at 4,379 mm (172.4 in). As a further comparison, a 2020 Chevrolet Corvette C8 is 4,630 mm (182.3 in) long.
The engine is a bespoke unit from Cosworth and Gordon Murray Automotive and has a redline of 12,100 revs. At 392 pounds, the company claims that this is the lightest road-going V12 ever. The powerplant displaces 3,994 cubic centimetres, although in the announcement the automaker refers to it as a 3.9-litre mill.
The engine runs through a six-speed manual gearbox. During development, the company paid special attention to making sure it had ideally light and crisp feeling when snicking the gearshift through the cogs.
The cabin also evokes the F1 by having the driver sit in the centre and the two occupants flanking the pilot. The important controls are on pods on each side of the steering wheel.
For the perfect fit, each buyer gets to meet with Gordon Murray Automotive to have the position for the seat, steering wheel, and pedals tailored to the person wants.
Gordon Murray Automotive plans to make just 100 units of the T.50, and the company is charging £2.36 million before taxes for them. Production of the T.50 starts in January 2022. The first deliveries will happen later that year.

Gordon Murray Automotive has unveiled its T.50 supercar in full for the first time, showing the finished exterior and interior design and confirming its ground-breaking technical specifications. The T.50 has been engineered to be the purest, lightest, most driver-centric supercar ever.
Improving on his acclaimed McLaren F1 “in every conceivable way”, Professor Gordon Murray CBE is leading the team that will begin building customer versions of the 986kg supercar in January 2022. Justifying its £2.36m (before taxes) price tag, the T.50 promises to deliver an unsurpassed driving experience. It is powered by a 100% bespoke 3.9-litre, 663PS V12 engine that revs to a record-breaking 12,100rpm, and features the most advanced and effective aerodynamics ever seen on a road car – aided by a 400mm rear-mounted fan.
The global premiere is the first time the clean lines of the exterior and the driver-focused interior have been seen. From his first ballpoint sketches, to every engineering and design detail, Murray has led the Gordon Murray Automotive team and briefed and overseen suppliers to drive the project forward at an unrelenting pace. Murray’s design for T.50 was the 50th in a prestigious line of race and road cars he’s penned over his illustrious 50-year career – both reasons combining to name the car T.50.
The most dominant characteristics of the T.50 exterior design are its purity and balance, free from the wings, skirts and vents that adorn most modern-day supercars. The clean surfaces are enabled by the most advanced and effective aerodynamics ever seen on a road car, resulting in deliberately simple, beautiful lines and a timeless appearance.
The purity of the silhouette is broken dramatically when the pair of dihedral doors rise up and forwards, coming to rest high above the passenger cabin. Inside, the driver-centric approach is plain to see – from the central, jet fighter-like driving position, to the aerospace-grade primary and secondary controls arranged in an ‘ergonomic bubble’ around the driver.
Quality of materials, the utmost precision, and simplicity of visuals define the whole car, but nowhere is this more evident than inside the cockpit. British suppliers are responsible for every major component throughout the interior, as well as every facet of the car’s exquisitely-engineered underpinnings – an attribute insisted upon by Murray who was determined the T.50 would be a true British sports car.
From the record-breaking V12 engine, and best lightweight transmission, to the world-first aerodynamic package and the feather-light titanium throttle pedal, every element is 100% bespoke and crafted by a British company that leads in its field. Murray pushed each supplier to their limits to deliver ingenuity, the highest quality and of course new levels of lightness.
With a vision that the car, and every element of its componentry, would be considered ‘engineering art’, Murray set out to create a vehicle that surpassed all others, fostering new levels of pride and connection among owners. Every T.50 customer has the opportunity to meet Murray to discuss their car and personalise it inside and out. Part of this process includes a seat, steering wheel and pedals ‘fitting’ session – personalised to every owner – that will ensure the T.50 is ergonomically perfect and individualised for each discerning customer.
Murray: “Just 100 customers will share my vision, a car created to improve on the F1 formula in every conceivable way. With 30 years of technological and systems advancement, now, the time is right to design the greatest analogue driver’s car. I believe no other company could deliver what we will bring to market in 2022, producing this British supercar will be my proudest moment.”
The T.50 mission – Driving perfection
Murray: “From the first touch of the titanium throttle pedal to the V12 screaming at 12,100rpm, the driver experience will surpass any supercar ever built. No other road car can deliver the package of power, instant responsiveness and driver feedback in such a direct and focused way while remaining comfortable, refined and usable every day.”
At the heart of T.50 ethos is the ultimate, sensory-rich driving experience, which all starts with the central driving position. The ‘jet-fighter’ style seating position affords an unhindered view out of the cabin, offering the type of pure driving experience usually associated with a single-seater race car layout.
Murray insists that the engine contributes to at least 50% of a great driving experience. With this in mind, Murray set out to create the greatest ever V12. The bespoke Cosworth GMA unit hits the mark as the world’s highest revving, fastest responding, most power dense, and lightest road-going V12. In terms of aural enjoyment, the T.50 raucous 12,100rpm redline will certainly deliver on wow-factor. The car also features Direct Path Induction Sound – a system pioneered on the McLaren F1 and refined on the T.50 to channel the sound of the throttle-induced induction growl into the cabin.
A cold-air ram induction intake sits immediately above the driver’s head, and carefully crafted carbon fibre panels in the roof act as a loudspeaker, amplifying engine sound within the cabin. The system is actuated by throttle angle and not revs, meaning the T.50 is quiet and refined on part throttle, growing louder as the throttle opens.
Inside the cabin, all of the T.50’s ergonomically-placed analogue controls are beautifully weighted. From communicative steering, which delivers pinpoint accuracy, to the weighting of the six-speed manual transmission and titanium throttle pedal, the engineering focus has always been on driving perfection.
During testing, the manual H-pattern gearchange motion and weighting was honed meticulously. Signed-off personally by Murray, the T.50 provides ‘the ultimate gearchange’ – a tactile short throw with a narrow cross gate for smooth, crisp, satisfying gearchanges.
The T.50’s kerb weight of 986kg makes it the lightest supercar of the modern era, lower than the average supercar weight by almost a third. Thanks to the focus on lightweighting, the car offers unparalleled levels of agility, responsiveness and driver focus. The T.50 is a car that is created to be ‘alive’ at normal road speeds, not only when the revs climb past 10,000rpm. It will entertain and engage on low-speed daily trips, as well as when driving on the open road just for the thrill of it.
With minimal interference from driver aids the driving experience is left to shine – importantly, ESP and traction control, can be disabled entirely. The technologies that do influence performance – for example, the six aero modes enabled through active and interactive fan-assisted aerodynamics – enhance rather than numb the drive experience. The 400mm rear-mounted fan expands the car’s performance capabilities significantly versus an ordinary ground-effect supercar. In partnership with the active rear spoilers and interactive diffusers, the fan helps to increase downforce by 50% (in Braking Mode 100% more downforce is generated); reduce drag by 12.5%; add around 50PS to the car’s output, in combination with ram-air induction; and cut braking distance by 10m from 150mph.
Sitting prominently at the rear of the car, the fan is just one example of ‘engineering art’ on the T.50. Another, about which Murray feels passionately, is the engine. Murray detests carbon or plastic engine covers so, upon raising the twin gullwing openings that span the rear half of the car, the Cosworth GMA V12 engine sits proudly on display with its cam covers, primary exhaust manifolds and inlet trumpets all taking centre stage.
It is Murray’s pride in perfection that has shaped every facet of the T.50. Calling the exterior styling “a return to beauty” the clean lines and visual balance seek to deliver a timeless design that will help the T.50 age gracefully, a fresh and lasting celebration of motoring engineering – the ultimate analogue supercar.
Commenting on the journey so far, Murray said: “For the past 18 months, the T.50 team has lived and breathed the ethos of the car, accomplishing everything we set out to achieve and more. I couldn’t be happier with the car and the team – they’re by far the best I’ve ever worked with.”

T.50 Press Kit
Chassis and body – carbon fibre throughout achieves rigidity and lightness
The chassis and body of the T.50 are entirely constructed from high-grade carbon fibre. Creating inherent stiffness and torsional rigidity, the carbon fibre plays an important role in making T.50 the world’s lightest supercar.
Murray: “With the design of our T.50 supercar, we are taking the same focused approach that was applied to the design of the McLaren F1. Thanks to modern materials and 30 years of development, we have been able to deliver a far better all-round car in the T.50, while setting its weight at just 986kg, a full 150kg lighter than the F1.”
At the core of the T.50 is a lightweight carbon fibre monocoque. It has been constructed by UK-based company Formaplex and features novel, cutting-edge part-bonded carbon fibre an aluminium honeycomb core. This construction method gives the T.50 exceptional structural rigidity, which benefits handling, agility and ride comfort.
The intrinsic strength of carbon fibre ensures exceptional occupant safety in the event of a crash. The carbon fibre panels feature precisely engineered deformable areas and the car also uses an F1-style ‘passenger safety cell’. The rigidity and torsional strength negate the need for additional bracing or reinforcement – another area of weight-saving.
The exterior body panels are also constructed from cutting-edge carbon fibre – including the front clam, the sculpted doors and the car’s rear panels. Remarkably, the T.50’s body, including the carbon monocoque and all body panels, tips the scales at less than 150kg.
The Cosworth GMA V12 engine and manual Xtrac gearbox are also semi-structural, being mounted to the chassis. The powertrain is attached using an inclined axis shear mounting system (IASA). The engine sits on anti-vibration mounts to prevent unwanted noise and vibration entering the cabin, while enabling the effective management of braking, acceleration and cornering forces. This saves 25kg of chassis weight at the rear of T.50, compared to a traditional engine mounting system.
Completing the lightweight structure is an ultra-lightweight windscreen, which is 28% thinner than a standard glass windscreen.
Aerodynamics – the most advanced aerodynamics of any road car
Murray: “We were focused on achieving the purest possible form for the T.50, an objective we’ve achieved through world-first engineering innovations and active underbody aerodynamics.”
The T.50 takes road-car aerodynamics to entirely new levels, with Murray rewriting the rule book to significantly enhance the supercar’s ground-effect capabilities. To achieve unmatched aerodynamic performance, the car’s rear-mounted 400mm fan rapidly accelerates air passing under the car, forcing it through active boundary-layer control ducts that form part of the rear diffuser.
Through the application of two automatic and four driver-selected aero modes, the T.50 is capable of increasing downforce by 50%; reducing drag by 12.5%; adding around 50PS to the car’s output in combination with ram-air induction; and cutting braking distance by 10m from 150mph.
The fan and its associated ducting system improve on conventional ground-effect systems by actively managing both underbody and overbody airflow. This boundary layer control ensures the most effective interaction of airflow on top of, and below the car, balancing drag and downforce at all speeds.
This same fan-assisted aerodynamic enhancement was first used for the road on Murray’s F1 supercar. Few realise that two fans had been employed to pull air from under the car as these, far smaller, fans were hidden beneath each of the F1’s rear haunches.
The underbody airflow system not only enhances performance, but also allows purity of design for the car’s upper surfaces. Air flows over the top of the car undisturbed by unsightly vents, ducts, or flaps. The fan interacts with a pair of active spoilers at the rear, which can contribute to downforce or reducing drag, as required.
The fan is driven by a lightweight 48-volt motor, spinning at up to 7,000rpm. The unit’s design and underbody ducting does away with the need for a ‘skirt’ – like that used by Murray’s Formula One BT46B Fan Car. Vertical inlet ducts fitted with filters ensure no road debris can pass through the fan.
The T.50 features six different aero modes that optimise performance for different scenarios to balance traction and outright performance. The fan aero system has six modes – two are automatic (Auto and Braking), the remaining four (High Downforce, Streamline, V-Max Boost and Test Mode) are driver selectable:
‘Auto Mode’ is the car’s default setting. In this mode, the T.50 operates like an ordinary supercar with passive ground-effect downforce.
‘Braking Mode’ automatically deploys the rear spoilers to their maximum (+45 degree) angle when high levels of deceleration are required. The fan also operates simultaneously at high speed while the diffuser valves open. This function can double downforce, enhancing stability and grip, and shortening the 150mph-to-0mph braking distance by a full 10 metres. If sudden deceleration is required, and when aerodynamics could influence stopping distance, Braking Mode overrides all other modes.
‘High Downforce Mode’ is driver selectable and delivers enhanced traction – in this mode, the rear spoilers deploy at +10 degrees, diffuser valves open, and the fan spools up to increase downforce by 50%.
‘Streamline Mode’ cuts drag by 12.5% and boosts straight-line speed while also reducing fuel consumption and downforce. In this mode, the rear spoilers deploy to -10 degrees reducing base suction and drag. The diffuser valves close partially, stalling the diffuser and reducing downforce, which saves wheel travel to make the car more comfortable and efficient. It also sets the fan to operate at high speed, drawing air from the top deck to minimise drag while extending the trailing wake of the car, creating a ‘virtual longtail’ and producing 15kg of thrust.
‘V-Max Boost’ is the most extreme T.50 mode. It uses the characteristics of Streamline Mode, then uses the car’s 48-volt integrated starter-generator to drive the fan – freeing up power to the driveshaft. Combined with the ram-air induction, this boosts power to 700PS for short bursts of acceleration.
‘Test Mode’ operates when the car is stationary and is driver-selected. The fan spools up to its maximum 7,000rpm, the twin rear spoilers cycle through their full range of movement and the diffuser ducts / valves progressively open and close before returning to their rest position.
Monitoring the level of static and underbody pressure provided by the combined fan and diffuser system is possible via an interior gauge – displayed on the left-hand dashboard screen.
Design – purity enabled through engineering
Murray: “Next-level aerodynamics allow us to avoid the current supercar trend for exaggerated wings, vents and ducts. I was determined to create a clean and pure shape that would remain timeless, ensuring the T.50 will still look fresh in 30 years.”
The most dominant characteristics of the T.50 design are purity and balance. Enabled by the most advanced and effective aerodynamics ever seen on a road car, the exterior of the T.50 indulges Murray’s preference for simple, timeless lines and clean surfaces. The design does not rely on wings, vents, or ducts to emphasise its performance capabilities. Instead the eye is drawn to the compact, balanced proportions and driver-centric symmetry.
Stylistically, the T.50 is far from drama-free. The remotely-released dihedral doors rise up and forwards creating a striking visual impact, as well as easing ingress and egress even in tight parking spaces. These doors are joined by a pair of glass-topped gullwing rear openings that hinge along the spine of the T.50 to reveal the V12 powertrain – crucially free form covers – making it easy to view and to access for maintenance.
Also revealed, running alongside the engine bay on either side of the car are a pair of 90-litre vertical-load luggage compartments. With all four doors open, revealing two-thirds of the car’s interior, the T.50 looks other worldly – like a predatory winged insect preparing for flight. Both the right and left-hand doors and engine cover doors can be opened remotely via the key.
As with every element of the T.50, the importance of the driver is very much evident in the styling. One of the car’s most noticeable design features highlights the central driving positing and natural balance that confers. A central line runs from the nose-mounted mermaid badge and continues into the cabin, over the instrument binnacle and bisecting the driver’s seat and continuing up the rear bulkhead. Outside, the line is mirrored by a tiny spine that runs from the base of the ram-air intake to the top edge of the fan housing at the rear.
This line emphasises the car’s symmetry and innate balance. From the front, a pair of the latest, high-intensity LED headlights offer a clear nod of recognition to Murray’s iconic F1. Each headlight features a pair of deep-set, horizontally aligned rings that operate as daytime-running lights and indicator lights. The centre of each ring features the dipped and main-beam lights bettering the previous industry-leading supercar headlight for reach and throw by 15%.
A heat sink and series of slits beneath and above the headlights circulate air around each fitting to cool the unit. Many manufacturers hide this cooling function, whereas Murray played to his ideal of creating ‘engineering art’ by turning this functional requirement into a distinctive styling element.
Following the central line up and over the sharply raked windscreen leads the eye to a roof-mounted ram-air induction inlet, which feeds the V12 and adds extra horsepower as the supercar gathers speed. Front to back, the roof is glazed either side of the central spine creating an incredibly spacious feeling interior and a sleek exterior appearance. As the spine falls towards the rear of the car the glazing continues, affording a glimpse of the V12 engine beneath its carbon fibre air box.
The rear deck is heavily sculpted to aid airflow towards the active spoilers. From the rear glazing, air flows beneath the rear deck to assist engine oil cooling – in streamline mode this air is channelled and ejected by the rear-mounted fan. The black inlet contrasts with the painted body and merges with the black fan housing that protrudes dramatically above the level of the rear deck and out beyond the trailing lip of the twin active spoilers that sit either side of the 400mm fan outlet.
Flanking the fan body are dual 80mm diameter exhaust outlets that sit within a black grille featuring an elongated-hexagon pattern that spans the full width of the rear end. At the rearmost outer corners of the car, circular red LED tail-lights draw the eye with their 3D transparent forms reflecting light outwards to create a stylish focal point. These units also act as rear turn indicators.
The profile of the T.50 is distinguished by the radiator exit duct behind the front wheel, the split side windows and the forged aluminium alloy wheels (19-inch front / 20-inch rear). Each side of the car also carries the name of the automotive division’s sister company: ‘Gordon Murray Design’ the business responsible for all of the car’s design and engineering.
In terms of overall proportions, the T.50 is extremely compact. Its 4,352mm length and 1,850mm width belie the generous interiors space, with room for three occupants and up to 288 litres of belongings. The addition of rear-view cameras (to be finalised during the next stage of the development process) will add no extra width and allow the car to avoid the weight, drag and unsightly clutter of external mirror housings. A third camera will sit in the centre spindle of the fan, providing a perfect rear view for reverse parking.
The Gordon Murray Automotive ‘mermaid badge’ sits proudly on the nose of the T.50. The company’s ‘new’ badge is probably the oldest automotive logo in the world. It has been in use by the Murray family since the 12th century. Also, acknowledging his family’s Scottish heritage, the blue, red and green colouring is the Murray clan tartan.
Engine – The greatest road-car V12 ever made
Murray: “To be truly remarkable, an engine needs to have the right characteristics: highly-responsive, an amazing sound, engaging torque delivery, free-revving, and it has to be naturally aspirated. For all those reasons, the engine in the T.50 was never going to be anything other than a V12.”
The 3.9-litre T.50 engine delivers maximum power (663PS) at 11,500rpm, on its way to a 12,100rpm redline. The Cosworth GMA V12 not only promises screaming high-end power, it is also extremely tractable for everyday driving. The maximum torque figure of 467Nm is produced at 9,000rpm, while the pick-up is a record-breaking 28,400 revs per second.
The T.50 has the highest power density (166PS-per-litre) of any road-going V12. It is also the lightest ever made thanks to a combination of exceptional design and lightweight materials (aluminium, steel and titanium) resulting in a total engine weight of just 178kg.
The meticulously designed and engineered powerplant draws upon the immense experience of Cosworth and Murray himself. It is the most engaging, characterful and driver-focused V12 engine ever produced.
Layering Murray’s depth of knowledge with Cosworth’s immense expertise in high-performance engines is what takes the T.50 V12 to another level. The name Cosworth is synonymous with racing – from Formula One, to rally, to IndyCar – as well as production of some of the most admired and successful supercar engines in the world.
With a focus on driver engagement, the T.50’s engine will be the highest-revving and most responsive naturally-aspirated engine ever fitted to a production road car. The V12 engine revs freely to a road-car record of 12,100rpm. Measured in revolutions gained per second, the T.50 will pick-up revs at 28,400 revs per second enabling it to hit its redline from idle in just 0.3 of a second.
Fed by a roof-mounted cold-air ram induction inlet, the T.50 powerplant delivers 71% of its peak torque from 2,500rpm, with its maximum (467Nm) achieved at 9,000rpm. This usability, and the outright performance of the engine is coupled to another major achievement: the Cosworth GMA unit produces the highest power density of any naturally aspirated road car engine – 166PS-per-litre.
Packing this amount of power into the world’s lightest road car V12 (just 178kg) required yet more innovation from Murray and the Cosworth team. To achieve Murray’s weight target, the block is made from a high-strength aluminium alloy and the connecting rods, valves and clutch housing are titanium.
Focusing again on the driving experience, Murray strived for the engine to have very compact external dimensions and the lowest possible centre of gravity. Here, reducing the F1’s 125mm crank height was the goal, a feat more than achieved by the Cosworth team – the T.50’s crank sits just 85mm from the bottom of the engine.
This accomplishment contributes in a very meaningful way to the dynamics of the T.50. The low centre of gravity means less pitch during cornering and braking, less squat and dive, plus better transient handling, meaning the T.50 will remain composed and balanced even at the extremes of performance.
Beneath the car’s two rear gullwing openings, Murrays motorsport heritage influences the appearance of the Cosworth GMA V12. Inspired by race car engines, it uses gear-driven ancillaries for lightness, with the added benefit of a clean and uncluttered engine bay. Murray was determined that the engine should be devoid of unsightly belts. All of the ancillaries are carefully positioned out of sight leaving the block heads, primary exhaust manifolds and inlet trumpets centre stage.
As well as effectively being an engineering work of art, T.50’s engine is semi-structural, providing much of the rigidity and weight saving found in a race car, without compromising driver comfort and cabin refinement. The semi-structural layout saves weight and increases stiffness while avoiding the noise, vibration and harshness penalties typically found with fully structural units, which increase cabin noise and hamper ride comfort.
As part of the early development process, the Cosworth team surpassed efficiency and emissions requirements and completed plans for two engine maps. These driver-selectable modes ensure the T.50 is not only the ultimate driver’s car, but is equally at home as a GT or a daily driver. While the engine offers usability and high-performance in either mode, ‘GT mode’ limits revs to 9,500rpm and with 600PS available, making the car even easier to drive around town.
If the driver selects ‘Power mode’, the full breadth of the car’s ability is unleashed, utilising all 663PS, and accessing the engine’s full 12,100rpm rev range. In this mode in particular, it promises to be one of the best sounding road car engines ever made – achieved partly through the extensive rev-range, but also influenced by the car’s Direct Path Induction Sound engineering, which channels the sound of the fabulous V12 into the cabin.
The T.50’s power and traction can be controlled by an electronic stability programme (ESP) and traction control system. With the driver aids engaged, the systems allow a progressive driving experience, while providing the driver greater confidence to explore the car’s limits in all weather conditions. Importantly, both systems can be switched off entirely should talented drivers want to fully explore the car’s capabilities.
Transmission – bespoke and lightweight – the ultimate gearshift
Murray: “The car’s six-speed H-pattern manual transmission is a tribute to Xtrac’s skill, continuing our focus on driver engagement. The gearchange motion and weighting was honed meticulously until we achieved the perfect end result. The outcome is a narrow cross gate and a short throw. It delivers slick, crisp gearchanges – truly a joy for the driving enthusiast.”
Being totally bespoke, it was possible to optimise every component of the gearbox for weight. Remarkably, the Xtrac team created a super-strong but extremely light aluminium housing that was cast at just 2.4mm thickness – resulting in a gearbox that not only met strict packaging requirements within the car, but also weighed in at just 80.5kg.
The transmission features five close ratios, geared for acceleration, with a longer sixth ratio for cruising. Reverse is selected having first flicked the red ‘lockout’ switch set next to the titanium gear lever.
Vehicle Dynamics – a focus on lightweight
Murray: “Weighing just 986kg, the T.50 undercuts the average supercar weight by almost a third. A heavy car can never deliver the dynamic attributes of a lighter car – even if it has the same power to weight ratio. While it is possible to disguise a heavy car’s dynamic capabilities with complex active suspension and sophisticated electronics, the agility, responsiveness and reward of a lightweight vehicle simply cannot be matched.”
In designing the T.50, Murray applied one of his core supercar philosophies, reversing the traditional focus on power-to-weight, to instead consider the vehicle’s ‘weight-to-power’ ratio. In the T.50, every 100PS has to propel just 150kg of car, whereas for the typical supercar (1,436kg with 693PS) the weight it has to shift is 40% higher, at 207kg. It is this weight-to-power calculation that drives the development of the T.50, with every component designed and engineered to achieve the lowest possible weight.
Powered by its 663PS V12 engine, the lightweight T.50 sets a challenging benchmark for rival supercars. To match the T.50’s 672PS/tonne, the typical 1,436kg supercar would need almost 300PS more power. But the 963PS required to match the T.50 on paper would add cost, complexity, and require larger, heavier components to handle the extra power.
Avoiding the weight-gain spiral caused by chasing top speeds and highest power output figures, Murray benchmarked the lowest possible weight for every component, right down to individual nuts and bolts. A key area where weight was minimised is the T.50’s fully carbon fibre monocoque and body panels, which total less than 150kg. Inside, three racing-inspired seats are also constructed using carbon fibre, with the centrally positioned driver’s seat and the passenger seats that flank it having a combined weight of just 13kg.
Throughout the early development process, weekly ‘weight watchers’ meetings at Gordon Murray Automotive scrutinised the weight of every component. Even the diameter and length of approx. 900 fixings was optimised to cut weight, taking account of the forces to which each would be exposed.
For the Gordon Murray Automotive team, no saving in weight was too insignificant, their focus on lightweighting has been unwavering. Every innovation, every iterative improvement supports the lightweighting strategy that helps create the purest, lightest, most driver-focused supercar ever.
This central mission promoted simplicity of construction and no compromise was tolerated, no expense was spared. The low total weight of the car means that the T.50 can use forged aluminium alloy double-wishbone rising rate suspension front and rear, with no additional interference required from heavy electric or hydraulic suspension components. The steering system is similarly pure, the simple rack-and-pinion setup is unassisted at speed, with the aim of ensuring a truly engaging driver feel, while there is low speed power assistance (LSPA) for parking.
The suspension and steering works in partnership with the Michelin Pilot Sport 4 S tyres (235 / 35 R 19 at the front and 295 / 30 R 20 at the rear). Chosen by Murray to avoid costly replacement of bespoke rubber and specified for superior all-round performance, the Michelin tyres are another weight-saving move as they can be far smaller and narrower than a typical supercar tyre due to the sprightly weight of the T.50.
T.50’s body and chassis are constructed almost entirely from carbon fibre, which ensures incredible stiffness, such that no additional bracing is required in the car. The structural stiffness ensures optimum handling, agility and ride comfort.
The T.50 also boasts race-car levels of agility and driver focus thanks to its low centre of gravity – afforded, primarily, by its semi-structural engine, which sits low in the chassis and delivers a very low polar moment of inertia.
Another of consideration for the vehicle’s dynamics was minimising un-sprung mass. Here, Murray applied a host of tactics that combine to keep weight down. The wheels, hubs, and suspension arms are all ultra-lightweight. The wheels are forged from a lightweight blend of aluminium alloy (front 7.8kg, rear 9.1kg), as are the suspension uprights and wishbones. While, for ultimate weight saving, the car’s hubs and bearing carriers mimic those of an F1 car, with a single locking nut, dramatically reducing the amount of material needed for their construction.
The T.50 is braked using the latest-generation Brembo six-piston air-cooled aluminium alloy Monobloc callipers on the front and four-piston air-cooled aluminium alloy Monobloc callipers on the rear. Optimum stopping power, and further weight saving, is ensured by pairing them with Brembo carbon ceramic brake discs (front 370mm x 34mm / rear 340mm x 34mm). The latest Brembo advancements enable these discs to be smaller than similarly-powered vehicles that don’t benefit from this newly-released technology. The car is also equipped with an anti-lock braking system.
The T.50’s braking setup will be subject to a rigorous testing and real-world fine-tuning regime during the forthcoming development period. The final outcome will be the ultimate braking system for the enthusiastic driver, with low levels of servo assistance making ‘heel-and-toe’ gear changes easy and natural. The carbon ceramic discs are calibrated to engage progressively and with a firm pedal feel – and will also naturally resist fade and a ‘long’ pedal during enthusiastic driving and repeated deceleration from high speeds.
Interior – a jet fighter cockpit for three
Murray: “Everything about the interior starts with the driver – the central driving position is the clearest demonstration of this approach. Building on this starting point, every control is arranged within easy reach of the driver. Purity of design was our goal, with the utmost quality applied to every element. The cabin is spacious and refined, making the T.50 exceptionally capable of traversing continents in comfort.”
From the outside looking in, the T.50 appears to be a single seater racing car. With intentional focus on the driver, Murray specified the driver’s seat to stand out in a vivid colour, while the two passenger seats that flank it are trimmed to blend in with the rear bulkhead.
As the dihedral doors lift, they present a wide opening that grants easy access to the cabin for driver and passengers. The design of the carbon fibre monocoque moves the need for torsion beams from the centre of the passenger compartment to the outside of the chassis, meaning the floor is free from obstruction.
Each customer will have a personalised seat fitting during the specification process, at the same time adjusting the steering wheel height and reach, and fine tuning the set-up of the pedal box.
In keeping with much of the rest of the car, each pedal is an engineering work of art. Milled from solid aluminium for strength and lightness and laser-etched with the T.50 name, the clutch and brake pedals both feature a web-like pattern to save weight and provide an anti-slip surface. The accelerator pedal is crafted from solid titanium to deliver the lightest, strongest pedal that delivers ultimate control and sensitivity to the driver.
To the right of the driver, the titanium gearstick sits on an arm that extends alongside the driver’s seat. The underside of the arm ‘floats’ above the cabin floor to reveal the expertly-crafted titanium gearchange mechanism.
The arm itself features a number of controls including the drive mode selector, infotainment rotary control, and most importantly a centrally-positioned engine start / stop button, sheathed beneath an anodised red jet fighter-style ‘missile switch’ cover. At the frontmost tip of the arm is an individually laser-etched chassis plate denoting the vehicle build number.
Once seated in the central driving position, the three-spoke carbon fibre steering wheel is pleasingly narrow-rimmed to afford a firm grip and transmit abundant feedback. Behind the wheel, a left- and right-hand paddles enable the driver to sound the horn or flash the headlights without taking their hands off the wheel. There are no touchscreens and no stalk controls – even the indicators are operated by thumb-buttons on the steering wheel’s horizontal spokes.
Every control is analogue, every display is designed for functional clarity, every primary and secondary control switch is satisfyingly tactile and ergonomically positioned for ease of use.
Front and centre in the driver’s view is a large (120mm) analogue, flood lit rev counter – its needle milled from aluminium. Either side of the steering wheel, three aerospace-grade aluminium rotary switches are positioned within easy reach. On the right, the switches control the heating / ventilation and air conditioning, while to the left the two lower controls are for wipers and lights. The top-left dial is the most intriguing and unique – marked with a graphic of the T.50 fan, this configures the four driver-selectable aero modes.
Everyday usability – the ultimate supercar that’s easy to live with
Murray: “Comfortable, refined, spacious and easy to drive – not a typical description for a supercar with the capabilities, power or driver focus of the T.50. I’ve designed this car to be used every day, with almost 300 litres of luggage and storage space, a premium stereo, and excellent air conditioning. From its exceptional visibility and compact footprint to ease of ingress and egress, the T.50 rewrites the supercar rule book for usability.”
The Gordon Murray Automotive team evaluated ease of access to the T.50 at length. More than 40 people of all ages and sizes took part in an assessment of a range of different seating permutations. The car’s dihedral doors were chosen to enhance the ease of getting in and out, while the sill of the carbon tub sits low to the ground and the flat cabin floor is free from obstructions across the full width of the car.
Once inside, visibility out is excellent, in no small part due to the central driving position. The car’s compact proportions mean that its footprint is comparable to that of an average C-segment hatchback, making it easy to park and place on narrow roads or in urban environments.
Passengers have a large amount of usable storage space, with a combined 30 litres of interior stowage across five compartments – one above each passenger’s footrest, another under each passenger seat, plus one behind the driver's headrest. Set within the left and right rear haunches of the car are vertical-load luggage compartments, each with around 90 litres of capacity – comfortably swallowing a flight case each side. When carrying three passengers, the luggage capacity totals 228 litres. However, by using a specially made suitcase that is sculpted to the shape of the passenger seat, two occupants can enjoy 288 litres of luggage / storage space.
In terms of daily use, the T.50 is quiet and easy to pilot. The engine map has two states of tune, one ‘Power Mode’ for maximum revs and the full 663PS, and a ‘GT Mode’ that limits revs to 9,500rpm and power to 600PS – ideal for urban commutes or relaxed touring.
Ensuring comfort and practicality around town, the T.50 has a 120mm front and 140mm rear ride height allowing it to easily clear speed bumps and other road furniture without damaging the car’s bodywork or causing discomfort.
Technology – all the driver essentials, no driver distractions
Every display in the T.50 is simple. White graphics on a plain black background ensure ease of use and quick recognition for the driver with minimal distraction. Even the rear-view displays are optimised for the driver, offering a better field of vision than mirrors and weighing significantly less.
Delivering a premium audio experience was a key element of the T.50 brief. Here Murray stuck to his key principals for the car; lightweight, highest-quality and British. Again, bucking industry trends, Murray enlisted high-end audio specialists Arcam to create a 700W nominal 10-speaker 100% bespoke sound system for the T.50.
Aligning with the car’s lightweight characteristics, the whole system weighs just 3.9kg and connects wirelessly to the driver’s phone to stream audio. The T.50 also uses Android Auto / Apple Car Play for all Bluetooth phone and navigation functions – which are displayed on the infotainment screen to the right of the rev counter.
Customer experience – the return of a true supercar owner’s experience
T.50 buyers have received bespoke and personalised service, from the first expression of interest and throughout the purchase, specification and manufacturing process. That same approach will continue for the duration of their ownership.
During the car’s development, owners have been given first sight of vehicle designs, engineering milestones and project updates. Moving closer to the car’s 2022 manufacturing date, customers will be invited to set up their car to fit them perfectly, while customisation of colours and interior will allow individualisation of the strictly limited 100 T.50 models.
Murray has met or spoken to every buyer and will hand over every car collected from the Gordon Murray Automotive’s UK customer reception centre. Around the world T.50 owners will have access to a service network in the UK, US, Japan, and Abu Dhabi – with a ‘flying technician’ service supporting these and all other markets.
Throughout the build of their car at Gordon Murray Automotive’s UK production base, customers will be kept informed of the status of their car and will have the option to visit their car during the build. Following collection, owners will be offered tailored experiences to continually enhance their ownership of the world’s most driver-centric supercar.
