Mercedes-AMG has finally started production of the One hypercar.
The development of The One has been difficult to say the least. There’s the mountain of getting a Formula 1 engine to run smoothly without an entire racing team – let alone convincing it to meet road regulations – and that’s before considering Covid and supply shortages .
But it doesn’t matter, because we are here now, and the One is working.
As mentioned, it uses the 1.6-litre hybrid turbo V6 from Lewis Hamilton’s 2017 racing prototype, but tweaked to produce around 422kW, compared to the F1 car’s around 670kW. This is largely due to the adjustment needed for road use, such as the idle rate dropping from about 4000 rpm to 1250 rpm, and the redline at 11000 rpm from 15,000 rpm. There are also six catalytic converters in play.

The engine itself is still largely F1, with spur gears controlling the cams, pneumatic valves in place of mechanical valves and an electric turbo.
Speaking of electrics, the One has no less than four electric motors dotted around the car. A 120 kW motor sits on the crank, two more are located on the front axle, and a smaller 90 kW motor is connected directly to the turbocharger to completely eliminate lag. In total, the electric motors add 450 kW of power.
Couple that with the combustion engine and the One delivers a total of 782kW. Torque is still unknown, apparently because the powertrain is “too complex”.
It doesn’t matter, because the hypercar will reach 100 km/h in 2.9 seconds, 200 km/h in seven seconds flat and 300 km/h in 15.6 seconds. The maximum speed is 352 km/h. Ridiculous? Sure, but that’s the whole point.
An 8.4kWh battery provides enough volts for electric-only driving up to 11 miles, but it’s not exactly a commuter, so that’s fine. The battery is there to enable those crazy speeds, although it helps keep fuel consumption at a remarkable 8.7 L/100 km.
The chassis is as exaggerated as the engine. It is a carbon fiber monocoque, which uses the seven-speed automatic transmission as a stressed element, like an F1 car. There’s a surrounding aluminum subframe with five-link suspension and adjustable front and rear struts with horizontal push rods, which apparently eliminates the need for a front anti-roll bar. traditional. AMG says the car will lower 37mm in full attack mode.
Brakes include a set of 398mm carbon ceramic discs up front, bitten by six-piston calipers, and 380mm discs at the rear with four-piston calipers.
Obviously, there is also a lot of aero. Movable flaps are integrated into the front splitter, the front wheel arch air vents and the rear wing.
The splitter and fender adjust to increase downforce or reduce drag, while arch vents reduce internal pressure in the wheel arches. There’s also that big fin running down the center of the engine compartment.
If the car seems almost more problematic than it’s worth, you’re not entirely alone in that regard. Apparently Mercedes-Benz CEO Ola Kallenius joked that the board was “drunk” when it approved the project in 2017. But it’s done now, and it looks unbelievable. Too bad it’s pure unobtanium.
