The M TwinPower Turbo engine in the BMW M4 Convertible.

At the core of the BMW M4 Convertible is the redeveloped M TwinPower Turbo straight six-cylinder petrol engine. With tremendous power and an unmistakeable sound, the interplay of optimally aligned motorsport technologies allows for direct power development with a boost of 431hp.

M TwinPower Turbo straight six-cylinder petrol engine.

The 3.0l M TwinPower Turbo straight six-cylinder engine combines the best of both worlds: high rev characteristics with up to 7,600 rpm and superior power with a maximum of 550 Nm torque. The 431hp M engine accelerates from 0 to 62mph in just 4.3 seconds (with M DCT Drivelogic). Bi-Turbo direct fuel injection and typical M fine-tuning ensure that the engine responds directly to the slightest nudge of the accelerator with enthusiastic boost and excellent torque. A motorsport suitable cooling concept as well as an additional oil sump cover and oil drain pump, the M engine is ready to take on any challenge. Numerous innovations like sleeveless construction or a lighter, forged crankshaft continue the intelligent lightweight concept, improve dynamics and acceleration, lower consumption and provide an optimal weight distribution of almost 50:50. The reward: unprecedented agile driving that’s impressively underscored by the unmistakeable sound of the M engine.
