Mercedes-AMG One

The powertrain of the Mercedes-AMG ONE is expected to be rated at 475–775 kW (646–1,054 PS; 637–1,039 hp) through a hybrid drivetrain that shares many features with modern Formula One cars. The car has five motors with different functions on board: one internal combustion engine (ICE) and four electric motors.

The Mercedes-AMG ONE will utilise a modified 1.6-litre turbocharged 90-degree V6 engine from the Mercedes-AMG F1 W07 F1 car, as confirmed by Mercedes-AMG board member Ola Källenius.[11][12] Modifications will be done to the engine due to the engine's illegality in RPM idle and redline. The head of Mercedes-AMG, Tobias Moers, states that the engine will be at 1,280 rpm when idle, and at 11,000 rpm when at its redline limit.[13] However, the engine will only last for 50,000 km (31,000 mi) and the owners will have to return their cars for engine refurbishment.[14] The ICE produces 558 kW (759 PS; 748 hp), with torque figures still unknown.[15]

The ICE will work in conjunction with four electric motors: a 120 kW (163 PS; 161 hp) Motor Generator Unit-Kinetic (MGU-K) coupled to the crankshaft, a 90 kW (122 PS; 121 hp) Motor Generator Unit-Heat (MGU-H) coupled to the turbocharger, and two 120 kW (163 PS; 161 hp) electric motors at the front axle.[2] The MGU-K and MGU-H are Formula One-style motors responsible for recovering energy and improving efficiency during operation of the car.[16] More specifically, the MGU-K serves to generate electricity during braking, while the MGU-H serves to eliminate turbocharger lag and improve throttle response by keeping the turbine spinning at high speeds.[2] The final two electric motors drive the front wheels to allow for an all-wheel drive drivetrain, and the sum of these four electric motors will contribute 450 kW (612 PS; 603 hp) effective power to the total power output figure of the ONE.[15]

The transmission will be an 8-speed single-clutch automated manual transmission variant (which is actually a similar type of transmission used in modern Formula 1 cars), and will deliver the bulk of the engine power and torque to the rear wheels. The use of a single-clutch over a dual-clutch transmission was due to AMG's engineers wanting to keep the car light and due to concerns over the dual-clutch's ability to handle the high-revving V6 ICE.[17]

The ONE has wheels made of aluminium alloy and carbon fibre with diameters of 19 inches at the front and 20 inches at the rear with centre-lock wheel nuts. The tyres are Michelin Pilot Sport Cup 2s with codes of 285/35 ZR 19 for the front and 335/30 ZR 20 for the rear. The brakes are ventilated carbon-ceramic discs.

Interior

The interior is mostly minimalist and driver-focused, continuing the Formula One theme of the ONE. This includes a Formula One-style steering wheel and pedals, and a driver-oriented central infotainment screen. There are some traditional luxury features in the interior, notably napa leather and hand stitching on the bucket seats.[18]

Rear view

The exterior of the car is designed primarily for aerodynamics, although it still maintains a profile reminiscent to a road legal car. The notable aerodynamic features include the large front air inlets, the roof-mounted air intake and the large aerodynamic fin extending down the back half of the car.[18]

The body will be made entirely of carbon fibre in line with its F1 counterpart, resulting in a final estimated kerb weight of around 1,200–1,300 kg (2,646–2,866 lb).[11][3]
