The production version of the Mercedes-AMG ONE brings the world’s most modern and efficient Formula 1 hybrid drive technology from the race track to the road for the first time. The performance hybrid produces a total output of 1063 horsepower (782 kW) from one combustion engine and four electric motors, with a top speed capped at 352 km/h. The extremely complex development was carried out in close cooperation with the Formula 1 experts at Mercedes-AMG High Performance Powertrains in Brixworth.
The E PERFORMANCE hybrid drive of the Mercedes-AMG ONE comes directly from Formula 1 and has been realised in close cooperation with the experts at Mercedes-AMG High Performance Powertrains in Brixworth. It consists of a highly integrated and intelligently networked unit comprising one hybrid, turbocharged combustion engine with a total of four electric motors. One has been integrated into the turbocharger, another has been installed directly on the combustion engine with a link to the crankcase and the two remaining motors drive the front wheels.
The 1.6-litre V6 hybrid petrol engine with electrically assisted single-turbocharging corresponds in its technology to the current Formula 1 power unit. The four overhead camshafts are driven by spur gears. To achieve high engine speeds, the mechanical valve springs have been replaced by pneumatic valve springs. The engine, mounted in mid-engine position in front of the rear axle, revs up to 11,000 rpm. However, for longer durability and the use of commercial super plus petrol, it deliberately stays below the F1 rev limit.
The high-revving power unit is boosted by a high-tech turbocharger. The exhaust gas turbine and compressor turbine are positioned at a distance from each other and connected by a shaft. This allows a lower installation position for the turbocharger. On the shaft is an approx. 90 kW electric motor. Electronically controlled, this drives the turbocharger shaft directly, accelerating the compressor wheel up to 100,000 rpm before the exhaust gas flow takes over. The Formula 1 designation for this unit is MGU-H (Motor Generator Unit Heat).
