It's finally here. Five and a half years after Mercedes-Benz first said they were going to shove a Formula 1 engine into a street-legal car, we finally have the finished product. The AMG One is alive, and it delivers on all the promises Mercedes made. There's an F1 engine at its core. It is road legal. And it packs a combined 1,049 bhp (782 kilowatts) from its hybrid powertrain.

"With the Mercedes-AMG One, we have more than pushed the boundaries. The immense technical challenges of making a modern Formula 1 powertrain suitable for everyday use on the road have undoubtedly pushed us to our limits," said Philipp Schiemer, chairman of the management board for Mercedes-AMG. "Many may have thought, during the development period, that the project was impossible to implement. However, the teams in Affalterbach and Great Britain never gave up and believed in themselves. I have the greatest respect for all the participants and I am proud of this teamwork."

F1 Engine In A Street Car

The heart of the AMG One is without question its engine. From the first announcement way back in 2017, it's been known that Mercedes was using a legit F1 engine for the One. It's also been a source of some frustration making it actually work in such an application. But work it does – the 1.6-litre V6 internal combustion engine spins to a glorious 11,000-rpm redline, using a single turbocharger with electric assist. The engine utilises double overhead camshafts, air spring valves, direction injection, and a complex exhaust gas cleaning system to produce 566 bhp (422 kW) on its own. And it still meets Euro 6 emission standards.

The amazing engine is only half the powertrain story, figuratively and literally. Four electric motors combine to give the One its overall 1,049-bhp rating and all-wheel-drive capability. Two motors are located in front at each wheel, generating 322 bhp combined. The third motor is installed with the gasoline engine, sending 161 bhp (120 kW) to the crankshaft. The fourth motor is the one tied to the high-tech turbocharger, which Mercedes-AMG says adds another 121 bhp (90 kW) to the mix. That motor can also recoup energy from the turbo as exhaust gases spin it up, which can be sent elsewhere.

Electrified For Shocking Performance

In addition to the engine, Mercedes engineers spent considerable time on the One's lithium-ion batteries. Being a plug-in hybrid, it doesn't carry the sheer number of batteries as you'd find on a pure EV – the total capacity is just 8.4 kWh. But keeping them cool was critical for optimum performance, leading Mercedes to utilise a complex liquid cooling system for each battery. This also allowed the automaker to keep battery weight down.

The result is a car with over 1,000 combined hp that maintains battery temperatures of around 45 degrees Celsius. It can go 11.2 miles on electric power alone, and it weighs approximately 1,695 kilograms (3,730 pounds). With all systems brought to bear, the One will accelerate from 0-62 mph (100 km/h) in 2.9 seconds, utilising its AMG 4Matic + all-wheel-drive system and new seven-speed automated manual transmission developed specifically for the hypercar. Perhaps more impressive is its 0-124 mph (0-200 km/h) time of just 7 seconds. Flat out, the AMG One will reach 219 mph.

This is a breaking story. New information will be added as it becomes available.
