Mercedes V6 hybrid Formula One power unit

(Redirected from Mercedes V6 Hybrid Formula One engine)

The Mercedes V6 hybrid Formula One power unit 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 use in Formula One. The engines were in use since the 2014 season by the Mercedes works team. Over years of development, engine power was increased from 840 horsepower at 15,000 rpm, to 1,030 horsepower at 15,000 rpm. Customer team engines were used by Williams, McLaren, Lotus, Manor Racing, Force India, Racing Point Force India, Racing Point and Aston Martin.

Having a successful run since the 2014 season, the Mercedes V6 Hybrid engine have become one of the most successful Formula One engines of all time.[3] Breaking the record for most wins in a season in 2016 (this has record since been surpassed by Honda with Red Bull Racing in 2023), as well as among many other major constructor and driver F1 records. Notably, Lewis Hamilton won a record breaking six driver's championships and Mercedes-AMG Petronas Formula One Team won a record breaking eight consecutive constructor's championships powered by the Mercedes V6 Hybrid engines.

Statistics

Mercedes-AMG W11 F1 car, powered by a Mercedes V6 Hybrid engine, it was one of the most successful F1 cars of all time

The Formula One regulations in 2014 saw Mercedes produce a unique hybrid 1.6-liter turbocharged V6 engine, that could produce a significant amount of power with less fuel consumption compared to Ferrari and Renault engines. It also featured the kinetic energy recovery system (MGU-K) and heat energy recovery system (MGU-H). The engine was soon proved to have a clear advantage over other engines, as cars powered by the Mercedes engine scored the majority of points during the 2014 season.[12] Since the introduction of this engine formula, Mercedes-powered cars scored pole position in 131 and won 123 of 226 races (as of the 2024 Las Vegas Grand Prix), and won 7 drivers' championships and 8 constructors' championships.

The Mercedes-AMG One production hypercar features a powertrain similar to modern Formula One cars. The production version of the car features 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] Modifications were done to the engine, resulting in a reduction in idle rpm and redline rpm among many other changes to make it road-legal. The modified internal combustion engine (ICE) produces a maximum power output of 422 kW (574 PS; 566 hp). Torque figures were unmeasurable due to the complex powertrain.[15]

The internal combustion engine works in conjunction with four electric motors; a 120 kW (163 PS; 161 hp) MGU-K coupled to the crankshaft, a 90 kW (122 PS; 121 hp) 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 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 and improve throttle response by keeping the turbine spinning at lower engine high speeds.[18] Two electric motors drive the front wheels and creates an all-wheel drive drivetrain, the sum of these four electric motors contribute 360 kW (489 PS; 483 hp) of effective power to the total power output figure of the AMG One.

The head of Mercedes-AMG, Tobias Moers, claimed that the engine idles at 1,280 rpm and 11,000 rpm at its redline limit. However, the engine will only last for 50,000 km (31,000 mi) and the owners would have to return their cars for an engine refurbishment costing 850,000 euros. This Formula One inspired powertrain helps the car attain a top speed of 352 km/h (219 mph). 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]
