Mercedes-AMG One

The Mercedes-AMG One (R50, stylized as ONE) is an upcoming limited-production plug-in hybrid sports car manufactured by Mercedes-AMG, featuring Formula One-derived technology.[4][5] It was unveiled at the 2017 International Motor Show Germany by Formula One driver Sir Lewis Hamilton and Head of Mercedes-Benz Dieter Zetsche.[6][7] The production of the car is planned to be 275 units at a price of US$2.72 million per unit, all of which have been already sold. Mercedes-AMG received orders for four times the production amount, but have stated that production will not be increased from the planned 275 units, in order to maintain the exclusivity of the car.[8]

Chronology
PredecessorMercedes-Benz CLK GTR Straßen Version

Currently, the car is at the concept state, since it has not reached homologation regulations yet.[9][10]

Development

AMG unveiled the concept version of the ONE, called the Project One, with nearly identical specifications to the production version. The production ONE will be evaluated on their performance, durability, and ability in Mercedes-Benz's proving grounds and on racing circuits. The head of Mercedes-AMG, Tobias Moers states that when "the time is right", Mercedes-AMG Petronas F1 team driver and seven-time champion Lewis Hamilton, who has worked on the development of the car will test the prototypes.[3]

Specifications

Powertrain

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.

Internal combustion engine
The Mercedes-AMG F1 W07 Hybrid (being driven by Lewis Hamilton in 2016). A car on which the engine and design of the ONE is based

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]

Electric motors

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]

Transmission

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]

Wheels

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 features
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]

Exterior features
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]

Chassis

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]

Performance
