The Mercedes V6 Hybrid Formula One engine, is a series of 1.6-liter, hybrid turbocharged V6 racing engines which features both a kinetic energy recovery system (MGU-K) and a heat energy recovery system (MGU-H), developed and produced by Mercedes-AMG High Performance Powertrains for Formula One. These engines were in use since 2014 by the Mercedes works team. Over years of development, the engine power managed to increase, from 840 horsepower at 15,000 rpm, to 1,070 horsepower at 15,000 rpm. Customer engines were used by Williams, McLaren, Lotus, Manor Racing, Force India, Racing Point Force India, Racing Point and Aston Martin.

Since the 2014 season, the Mercedes V6 Hybrid engine was proved to be one of the most successful Formula One engines of all time.[3] Breaking the record for most wins in a season in 2016, as well as among many other major constructor and driver F1 records. Notably, Lewis Hamilton became one of the most successful Formula One drivers by winning six Driver's Championships and Mercedes-AMG Petronas Formula One Team won a record breaking eight consecutive Constructor's Championships in F1 cars, which were powered by these Mercedes V6 Hybrid engines.

The Formula One regulations in 2014 saw Mercedes produce a hybrid 1.6-liter turbocharged V6 engine, which features a kinetic energy recovery system (MGU-K) and a heat energy recovery system (MGU-H). The engine started the season with a clear advantage, with these Mercedes engined cars scoring the majority of the points.[12] Since the introduction of this engine formula, Mercedes powered cars have achieved pole position in 121 and won 114 of the 187 races (as of the 2023 Miami Grand Prix), and won 7 Drivers' Championships and 8 Constructors' Championships.

The Mercedes-AMG ONE production hypercar features a similar powertrain as in modern Formula One cars. Production version of the car is based on a modified version of the 1.6 L (98 cu in) Mercedes-Benz PU106B Hybrid E-turbo V6 engine, used in the Mercedes F1 W06 Hybrid Formula One car.[13][14] Some modifications were done to the engine due to the engine's illegality in RPM idle and redline. The modified internal combustion engine (ICE) produces a maximum power output of 422 kW (574 PS; 566 hp). Torque figures are unknown due to the complex powertrain.[15]

The internal combustion engine works 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 electric motors in the front axle producing 240 kW (326 PS; 322 hp).[16] The ONE has a total combined power output of 782 kW (1,063 PS; 1,049 hp). The MGU-K and MGU-H are similar as in use in Formula One cars, which were responsible for recovering energy and improving efficiency during operation of the car.[17] 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.[18] 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 contributes 360 kW (489 PS; 483 hp) effective power to the total power output figure of the AMG ONE.

The head of Mercedes-AMG, Tobias Moers, states that the engine will be at 1,280 rpm when in idle, and at 11,000 rpm when at its redline limit. 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. This Formula One inspired powertrain helps the car to attain a top speed of 219 mph (352 km/h). According to Mercedes-AMG, the car can accelerate from 0 to 100 km/h (62 mph) in 2.9 seconds, 0 to 200 km/h (120 mph) in 7.0 seconds and 0 to 300 km/h (190 mph) in 15.6 seconds.[19]
