Exterior features
The exterior of the car is designed primarily for better aerodynamics. Notable aerodynamic features include; moveable slats which were specifically developed for the front wheelhouses, two-part extendable rear wing with DRS system and active flaps on the front diffuser which were adjustable to suit the driver chosen driving program. Additionally, large front air inlets, roof-mounted air intake, large aerodynamic fin extending down the back half of the car and aerodynamically optimized wheels to aid generate more downforce in order to carry the maximum speed at highspeed corners.
Powertrain
The powertrain of the Mercedes-AMG One is rated at 782 kW through a hybrid drivetrain that shares many features with modern F1 cars. The car has an internal combustion engine and four electric motors.
Internal combustion engine
The car on which the engine and design of the One is based on is the Mercedes-AMG F1 W06, as confirmed by Mercedes-AMG board member Ola Källenius. The Mercedes-AMG One utilises a modified version of the Mercedes-Benz PU106B Hybrid engine, a 1.6-litre turbocharged 90-degree V6 engine.[11][12] Modifications were done to the engine as to make comply with the idle RPM and redline regulations. Tobias Moers, claimed that the engine would be at 1,280 rpm at idle, and 11,000 rpm at its redline limit.[13] However, the engine would only last for 50,000 km and the owners will have to return their cars for an engine refurbishment.[14] The ICE produces 422 kW, torque figures were claimed to be unmeasurable due to the complex drivetrain. Top speed of this car is limited at 219 mph (352 km/h).[15]
Electric motors
The internal combustion engine works in conjunction with four electric motors: a 120 kW motor generator unit-kinetic (MGU-K) coupled to the crankshaft, a 90 kW motor generator unit-heat (MGU-H) coupled to the turbocharger, and two 120 kW electric motors at the front axle.[16] The MGU-K and MGU-H are Formula One-style motors responsible for recovering energy and improving efficiency during the operation of the car.[17] More specifically, the MGU-K serves to generate electricity during braking, while the MGU-H serves to eliminate turbo lag in order to improve throttle response by keeping the turbine spinning at lower engine speeds and also to recover waste energy from the exhaust.[16] The final two electric motors driving the front wheels make up for an all-wheel drive drivetrain, the sum of these four electric motors contribute 360 kW of effective power to the total power output figure of the AMG One.[15]

Transmission
The AMG One features a 7-speed single-clutch automated manual transmission with 4-disc carbon racing clutch (similar to the type of transmission used in modern F1 cars), and delivers 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 engineers wanting to keep the car light and concerns over the dual-clutch's ability to handle the high-revving ICE.[18][19]
Suspension and wheels
The car contains a five-link aluminium coil-over suspension setup with two transverse adjustable push-rod spring struts, including adaptive damping adjustments. Rear axle links are shaped for better aerodynamics. It also features the hydraulic AMG carbon-fibre ceramic high-performance composite brake system, with 398 x 38 mm front composite brake discs, ventilated with 6-piston aluminium fixed callipers. 380 x 34 mm rear composite brake discs, ventilated with 4-piston aluminium fixed callipers. Additionally electric parking brake, ABS, brake assist and 3-stage ESP were also offered for the car.
The AMG One also has unique 10-spoke forged aluminium alloy wheels emerged with NACA carbon fibre openings for brake cooling and increase downforce. Also, with diameters of 19 inches at the front and 20 inches at the rear with F1-styled centre-lock wheel nuts. The tyres are semi-slick Michelin Pilot Sport Cup 2Rs 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.[19]
Interior features
The interior is mostly minimalist and driver-focused, continuing the F1 theme of the AMG One. This includes AMG Motorsport bucket seats, integrated into the carbon monocoque, a F1-style steering wheel with knobs for driving programs including; DRS, overtake etc. Paddle shifters and a driver-oriented central infotainment screen were also featured in the car. There are some traditional luxury features in the interior, notably the napa leather and hand stitching on the bucket seats.[20][19]
Chassis
The body is made entirely out of carbon fiber in line with its F1 counterpart, resulting in a final kerb weight of 1695 kg.[11][8] The car also features the F1 inspired exhaust tailpipe with a large round main outlet and two smaller outlets.
