Bringing Formula 1 to the streets – all you need to know about the Mercedes-AMG Project ONE

In 2017, Mercedes-Benz in collaboration with Mercedes-AMG announced the world premiere of the Mercedes-AMG Project ONE at the International Motor Show (IAA) in Frankfurt. The two-seater supersports show car has since boasted of 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. Two years on since the Mercedes–AMG Project ONE first premiered, 275 units of the supersports show car have gone into production with each unit going for a reported price tag of $2.7 million. Here are some of the highlights of the Mercedes–AMG Project ONE.

Exterior design: Beauty and the beast

The design of the show car is very obviously inspired by the premium class in motorsport. But above all, it embodies the Mercedes-AMG principle that fascination is always linked with function. Every part has a specific purpose. The result is a mid-engine concept, extremely muscular proportions with the cockpit well forward, large wheel arches, a wasp waist and an extended rear end.

"The Mercedes-AMG Project ONE is the hottest and coolest car we have ever designed. It combines our design philosophy of Sensual Purity with the performance of our Formula 1 racing cars and is the perfect embodiment of Performance Luxury," says Gorden Wagener, Chief Design Officer Daimler AG. "This hypercar's extreme design marks a milestone in design ‑ there are no lines, and the interior is stripped down to the essentials."

Interior: Formula 1 for two

The interior design concept follows function on the racetrack, and this is expressed in the radical design idiom. Formula 1 technology is made authentically tangible on both the race track and the road. Here too every detail has a function, with nothing included merely for visual reasons. In the monocoque interior, the reduced components are emphasised in minimalist style both in design and functional terms.

The ergonomically contoured interior has room for two occupants. The bucket seats with adjustable backrests are integrated into the monocoque. The pedals and steering wheel are adjustable, allowing the driver to adopt the ideal driving position. The centre tunnel visually separates the driver and passenger areas from each other. It blends fully into the seat sculpture and follows the principle of minimalism with its gently rising contour.

Formula 1-style steering wheel

The steering wheel with flattened upper and lower sections and an integrated airbag offers motorsport functionality, as do the two integrated controllers which can be used to set adjustment functions, such as the driving modes and suspension setup, or the LED shift display in the upper steering wheel area.

The door panels are in functional, high-grade carbon-fibre, and integrate smoothly into the sporty interior. As if to mirror the aero winglets of the exterior, the door panelling is visually interrupted to create space for technical implements and a generously concave door centre panel. An aluminium cassette combines the air vents and power window switches, which are integrated as deeply recessed rectangles.

Powertrain: one turbocharged 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 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).

Completely new, 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 basis for the outstanding driving characteristics of the Mercedes-AMG Project ONE is provided by the lightweight, high-strength carbon-fibre monocoque body, the technology of which likewise comes from Formula 1. The same applies to integration of the engine and transmission: both have load-bearing functions and completely support the rear suspension.

Colours and materials from the racing car

The choice of colours and materials takes its inspiration from the Mercedes-AMG Petronas Formula 1 racing car. The sculptured racing seats are in slip-resistant black microfibre, creating an unmistakable association with motor racing. The seat surfaces are interspersed with nappa leather in magma grey and inlays in a sporty textile mesh which optimally assists the air circulation of the seats. There is also yellow contrasting topstitching.

The Mercedes-AMG Project ONE: the future of driving performance

Conclusion: The Mercedes-AMG Project ONE will not only bring 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. The Project ONE team is working hard on successfully bringing this vision onto the road.
