The four electric motors include those used on more recent Mercedes-AMG grand prix cars. A 121bhp motor is housed on a shaft between the turbocharger and the electric compressor, while a 161bhp motor is positioned on the engine, connected to the driveshaft. The further two motors, making 161bhp, are integrated in the front axle.
Overall power is 1049bhp – 329bhp more than the previous most powerful AMG road car, the Mercedes-AMG GT Black Series. By comparison, the Aston Valkyrie develops 1160bhp and the Ferrari SF90 Stradale 986bhp.
Mercedes-AMG does not quote a torque figure for the One, because “the complex nature of the drivetrain doesn’t allow a representative figure”. It does, however, claim the One can sprint from 0-62mph in 2.9sec, 0-124mph in 7.0sec and 0-186mph in 15.6sec.
Drive is sent through a newly developed seven-speed automated manual gearbox featuring hydraulic operation, a four-disc clutch and steering wheel-mounted shift paddles.
There are six driving modes: Race Safe, Race, EV, Individual, Race Plus and Strat 2, the last two reserved for track use.
Race Safe provides ondemand hybrid properties from the powertrain. In Race, the engine is always engaged and is used to charge the battery. EV is a pure-electric mode.
