M8 GTE’s V8 Turbo Is BMW’s Most Efficient Race Engine Ever

BMW has shed more light into the powertrain that motivates the M8 GTE race car.

After more than 500 engine design drawings and another 500 for the powertrain, BMW Motorsport’s most comprehensive project since their DTM return in 2012 has resulted in the most efficient race engine they’ve ever built.

Codenamed P63/1, the M8 GTE’s engine is based on the twin-turbo S63T4 V8 engine which can be found in the latest BMW M5. Depending on the specifications of the racing series, the engine is capable of delivering between 500 and 600 horsepower.

Cast parts in the engine block and cylinder head are left unmodified as instructed by the regulations, but the rest of the engine uses 985 unique parts. Capacity is also reduced down to 4.0 liters from the production unit’s 4.4 liters.

A flat crankshaft means that there’s now a regular firing order which gives the engine a raw soundtrack while the geometry of the combustion chambers was also modified to better suit the demands of racing.

The end result is a race engine with an efficiency level of over 40 percent, making the P63/1 the most efficient engine BMW Motorsport has ever built for a sports car and touring car racing.

BMW Motorsport also compliments the driveability of the P63/1 by saying that is outstanding thanks to a completely new approach to engine control that allows instant throttle response and linear power delivery.

The new BMW M8 GTE will compete in the FIA World Endurance Championship and the IMSA WeatherTech SportsCar Championship in 2018.

    I’m sorry but I’m going to be a little tough-
    This video means nothing if that engine will not be in the new 8-Series- and it won’t.
    At this point it’s clear from the prototypes that the new 8 looks nothing like the show car
    from last year. That’s a fail BMW. Chances are it will be another fat-bloated 6 with an 8
    on the rear. I hope not. Saving praise until the reveal. That goes for the Z4/5 too.
