Mercedes-AMG Project ONE: Formula 1 technology for the road
World premiere at the IAA
The Mercedes-AMG Project ONE will celebrate its world premiere at the International Motor Show (IAA) in Frankfurt/Main: for the first time, the two-seater supersports show car brings the very latest and efficient, fully-fledged Formula 1 hybrid technology from the race track to the road almost par for par to represent the highlight of AMG’s 50th anniversary. This high-performance hybrid is said to produce over 1,000 PS and reach top speeds beyond 350 km/h. The show car combines outstanding race track performance and day-to-day suitable Formula 1 hybrid technology with exemplary efficiency. This is a world first.
One turbo engine and four electric motors
The high-performance plug-in hybrid drive system of the Mercedes-AMG Project ONE comes directly from Formula 1, and was realized 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.
Rear mid-engine with up to 11,000 rpm
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. To achieve high engine speeds, the mechanical valve springs have been replaced by pneumatic valve springs.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.
Driving Performance of the future
Ever since the early days of motorsport, engineers have dreamed of bringing motor racing technology to the road. Mercedes-AMG is now making this dream a reality at the very highest level. “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-BenzCars.
The concept car gives specific indications of what to expect from the upcoming production model. “The hypercar is the most ambitious project we have ever undertaken. It marks yet another pinnacle of the successful, strategic development of Mercedes-AMG towards a performance and sports car brand. Project ONE raises the bar in terms of what is currently technologically feasible and thanks to its combination of efficiency and performance it represents an absolute benchmark. At the same time, Project ONE provides an outlook on how AMG will define driving performance in the future”, Tobias Moers explains as the Head of Management at Mercedes-AMG GmbH.
Impressive acceleration figures
The driver can move off purely electrically, initially with just the electric motors on the front axle driving the hypercar and the electric motor on the crankshaft supporting short-term acceleration wishes. If the driver presses the accelerator more firmly and demands more output, the V6 engine also switches on. The drive system unfolds its full power as the engine speed increases. Impressive acceleration figures are possible with the Race Start function: acceleration from zero to 200 km/h takes under six seconds. If the driver’s foot leaves the accelerator again to let the car coast, the system switches to electric drive at the front axle – whilst braking under normal driving conditions recuperates up to 80 percent of the energy, which is fed into the battery.
Automated 8-speed manual transmission
Power is transferred to the rear wheels by an 8-speed manual transmission that has been entirely developed from scratch for the Mercedes-AMG Project ONE. It is activated hydraulically and can be operated in automated mode or manually using the shift paddles. The car is equipped with an advanced, weight-optimised ceramic high-performance compound braking system. Its low weight reduces the unsprung masses, thus improving driving dynamics and agility.
Innovative pushrod suspension
Multi-link designs are used at the front and rear. The adjustable coil-over suspension has several special features: Both push-rod spring struts have been installed across the direction of travel. The innovative arrangement of the spring/damper unit replaces the function and application of conventional tubular cross members. The overall setup of the springs and dampers is configured for perfectly balanced, easily controlled and above all sporty handling characteristics. These are also assisted by all-wheel drive and torque vectoring.
Not only a street-legal racing machine
The Mercedes-AMG Project ONE will not only be a street-legal racing machine that directly brings current Formula 1 hybrid technology onto the road and combines top-class race track performance with full day-to-day suitability. Its purpose is also to obtain extensive findings about performance-oriented plug-in hybrid drive technology, further developments of suspension layouts and extended onboard electronics that will later benefit series production AMG cars.
