Newly designed piston rings are used in the engine. The two turbo chargers use turbines made from high tensile steel and will easily withstand temperatures of up to 1000 degrees Celsius.

The direct fuel injection contributes significantly to the high degree of efficiency of the engine, which uses Piezo injectors arranged centrally between the valves to ensure a particularly precisely dosed fuel supply.

The high degree of compression also increases the effectiveness. In addition, measures such as brake energy recycling and demand-controlled ancillary units are also used, so that the M engine of the BMW Series 1 M Coupé unites fascinating performance with great efficiency. This is something that will also be important for drivers with a sporting interest - after all fewer pit stops never did anyone any harm.

The compact six-speed transmission with dry sump lubrication is a new development. Its suitability for high torques is combined with a weight of just 43 kg – much lighter than similar gearboxes. The short M gear lever underlines the crisp and precise gear change – the traditional sportiness of this elite class.

Because the drive shaft is also a new part, every ing is specifically tailored to the requirements of the BMW Series 1 M Coupé in this combination, starting from the flange of the crank shaft.
