BMW 6 Series Convertible : BMW TwinPower Turbo straight 6-cylinder petrol engine

BMW TwinPower Turbo inline
6-cylinder petrol engine in the BMW 640i.

Self-assured power build-up, silky smooth, cultivated performance: the strengths of the BMW inline 6-cylinder are legendary. With each new generation, BMW has continued to refine the engine while at the same increasing its dynamics and efficiency. The BMW 640i represents another highlight in this success story.

235 kW (320 hp) and 450 newton metres, only 7.9 to 7.8 l/100 km, 185 to 181 g CO2/km and acceleration of 0 to 100 km/h in 5.5 seconds. Revolutionary technologies and innovative fine tuning interact to complement and stimulate each other in the BMW TwinPower Turbo of the BMW 640i.

TwinScroll turbocharger and Valvetronic bring a breath of fresh air into the combustion chamber, where petrol direct injection generates clouds of a precisely adjusted petrol-air mixture within milliseconds while the double-VANOS optimally adapt the engine performance across the speed range. The result is maximum efficiency particularly when full power is not required, maximum power over a broad band of revs and a direct response at all times. In short, an engine that does justice to the BMW 640i.

The BMW 640i fulfils the EU6 emission norm as standard.
