The Mercedes-AMG Project ONE hybrid supercar is now being shown at the Frankfurt Motor Show. With over 1,000 hp from its hybrid powerplant, the supercar is capable of hitting a top speed of over 350 kph and provides an insight into the future performance-hybrid drive strategy of the sports car brand within Mercedes-Benz.
"Motorsport is not an end in itself for us. Faced with intense competition, we develop technologies from which our production vehicles also subsequently benefit. We are drawing on our experiences and successes from three constructors' and drivers' world championships to bring Formula 1 technology to the road for the first time, in Mercedes-AMG Project ONE," says Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars.
"The Mercedes-AMG Project ONE is the first Formula 1 car with MOT approval. Our highly efficient hybrid assembly stems from motor racing and the electrically powered front axle generates a fascinating mixture of performance and efficiency. With a system output of over 1,000 hp and a top speed beyond 350 km/h this hypercar handles exactly as it looks - it takes your breath away," says Ola Källenius, Member of the Daimler AG Board of Management responsible for Group Research and Mercedes-Benz Cars Development.
The high-performance plug-in hybrid drive system of the Mercedes-AMG Project ONE comes directly from Formula 1, and was realised in close cooperation with the motorsport experts of 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 direct injection and electrically assisted single turbocharging comes directly from the Mercedes-AMG Petronas Formula 1 racing car. 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 To achieve high engine speeds, the mechanical valve springs have been replaced by pneumatic valve springs.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 vehicle is mid-engined (ahead of the rear axle) and it can easily reach speeds of 11,000 rpm, which is currently unique for a roadgoing vehicle. However, for higher longevity and the use of commercially available Super Plus petrol instead of racing fuel, it remains significantly below the F1 engine speed limit.
The electric motors on the front axle are also true rev wonders, with rotor revolutions up to 50,000 rpm – current state of the art is a speed of 20,000 rpm. The very high-revving engine is additionally boosted by a high-tech turbocharger. The exhaust gas and compressor turbines are separated from one another and located at an optimum position to the exhaust side and to the intake side of the V6 engine, and connected to one another by a shaft. This shaft features an electric motor with approximately 90 kW which, depending on the operating status, electrically drives the compressor turbine with up to 100,000 rpm – for instance when moving off or following load changes. The Formula 1 designation for this unit is MGU-H (Motor Generator Unit Heat).
With this new hybrid supercar, Mercedes-AMG firmly establishes future directions for the development of hybrid and electric high-performance vehicles.
