However, the quantity of battery cells in the AMG Project ONE will make it significantly more practical for everyday use. The lithium-ion, high-voltage battery and the DC/DC converter supporting and charging the 12 V onboard electrical system are space-savingly accommodated in the vehicle floor behind the front axle.

As a further innovation, the high-voltage EQ Power+ drive system operates with 800 volts instead of the usual 400 volts. Thanks to the higher voltage levels it is possible to influence elements, such as significantly reducing the cable diameters and accordingly saving design space and weight.

Overall the high-performance EQ Power+ plug-in hybrid drive system offers numerous intelligent operating strategies which are optimally tuned to different application scenarios. The driving modes range from purely electric operation through to a highly dynamic mode which corresponds to a setting used in Formula 1 qualifying for optimum lap times. Despite the high system complexity, and depending on the current requirement, the driver will always receive the optimum combination of performance and efficiency. In this process, Mercedes-AMG engineers make use of the many years of experience and know-how from Formula 1, the SLS AMG Electric Drive and Daimler AG's research and development.

For instance, 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.

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.

The suspension developers also gave their utmost. 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. This solution reliably prevents rolling movements even during very rapid directional changes, without being uncomfortable.

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. ABS is standard equipment, with ESP® adjustable in three stages as is usual for AMG. ESP® ON stands for a high level of safety, ESP® SPORT HANDLING MODE allows greater yaw angles before system intervention for a sporty driving style, and ESP® OFF switches the system off for sporty driving on enclosed racetracks.

Another completely new development is the 10-spoke forged aluminium wheel with centre lock, which is exclusively reserved for the Mercedes-AMG Project ONE. This has a radial carbon-fibre semi-cover with an aerodynamically sophisticated shape: this improves the car's aerodynamics and Cd figure by optimising the airflow around the wheels.

At the same time, three flat ventilation slots per spoke section ensure optimum heat dissipation from the brakes. This is another example of how the AMG development team pays the utmost attention to even the smallest aspects, so as to improve the efficiency of the hypercar.

At the front the Mercedes-AMG Project ONE runs on 10.0 J x 19 dimension wheels and 285/35 ZR 19 Michelin Pilot Sport Cup 2 tyres which were exclusively developed for the hypercar and at the rear the vehicle features 12.0 J x 20 wheels running on Michelin Pilot Sport Cup 2 335/30 ZR 20 tyres.

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. Furthermore, the ceramic brakes are distinguished by a longer service life, higher corrosion resistance and higher thermal stability. The "AMG Carbon Ceramic" lettering and the specially painted brake callipers visually distinguish this unique braking system.
