If you want to break records in this day and age you don't always need a jet powered supercar spaceship thing, although they do help.

No, lap records can be family affairs now, and Jaguar has just broken the four-door lap record at the famous at WeatherTech Raceway Laguna Seca in Monterey, California, proving that cars with room for the kids can be record-breakers as well.

Okay, so we admit, the car used wasn't exactly ideal for the school run, but still...

More Jaguar Project 8

The Jaguar XE Project 8 is the quickest, most powerful road-legal car ever made by Jaguar. Powered by a fire-breathing 592 bhp supercharged V8, it can launch from 0-60 mph in a supercar-like 3.3 sec and go on to a (limited) top speed of 200 mph.

"This Laguna Seca lap record is another powerful demonstration of the Jaguar XE SV Project 8’s performance credentials," said Michael van der Sande, Jaguar Land Rover Special Operations Managing Director. "Designed, engineered and hand-assembled by Special Vehicle Operations, this record-breaking sedan is made for the world’s most demanding driving enthusiasts."

The Project 8 was developed by Jaguar Land Rover's Special Vehicles operations division, and while it is based on the standard XE's lightweight aluminium-intensive monocoque, it is anything but normal. Just 300 will be made, all hand built at JLR's SV Technical Centre in Coventry, and have specially been modified to accommodate Jaguar's 5.0-litre V8 engine and a bespoke rear differential.

There's other 'not-so-normal' features too, like F1-style ceramic wheel bearings, adjustable ride height and adjustable camber, and flared front and rear fenders to accommodate larger, wider, wheels which are necessitated by the larger brakes. The transmission is also a high-performance tweak – an eight-speed Quickshift automatic ZF transmission. The car has also received significant aerodynamic and suspension upgrades, including a 'Track' which gives maximum downforce and further enhances the damping, throttle response and steering response.

If you want your own Project 8, you might want to start looking down the back of the sofa. They are still available, but they start from £149,99. It's available in two different specifications – a 'standard' four-seat model with Jaguar’s latest front Performance seats with magnesium frames, plus a more heavily contoured rear squab to maximise support; or there's the optional two-seat Track Pack which includes lightweight front carbon fibre racing seats with four-point harnesses fixed to a harness retention hoop which takes the place of the rear seat.
