Motor is based on M5’s 4.4-liter biturbo engine.
BMW has released the first teaser image of its reborn 8 Series coupe. The sexy coupe has been in the final stages of development and is ready to race on the track. Bavarian firm has released technical details about the engine of the beast, the M8 GTE.
The race car will compete at the FIA World Endurance Championships (WEC) as well as the IMSA WeatherTech SportsCar Championship (IMSA WeatherTech SportsCar Championship) in 2018. It is powered by a 4.0-liter V8 engine code P63/1. The engine produces between 500 horsepower (373 kilowatts), and 600 horsepower (447 kW), depending upon the specification. It is the “most efficient BMW Motorsport racing engine” according to the automaker. The engine’s design required 500 drawings for engine design and 500 more drawings for powertrain.
This motor was actually inspired by the BMW M5 engine and was developed with input from BMW’s M division. Some of the parts from the production engine, such as the engine block or cylinder head are used in this race engine. Apart from that, almost 1,000 parts are used in the race car engine. 700 of these were specifically designed for the P63/1 unit.
The engine’s unique elements include the design of the combustion chambers including the inlet, outlet, and intake ports. Also, the turbochargers have undergone a complete redesign. BMW claims that these improvements over the production V8 combined with a new engine controller result in efficiency levels of well over 40 percent. They also claim an “instant throttle response” and “linear power delivery from the engine.”
