BMW TwinPower Turbo straight 6-cylinder diesel engine in the BMW 640d.
The new BMW 640d inspires heart and mind: with strong performance, rapid power build-up and low consumption. The innovative BMW TwinPower Turbo technology combines common-rail direct injection and multistage turbocharging with variable turbine geometry.
This significantly reduces fuel consumption while, at the same time, greatly increasing power. A high torque of 630 Nm is available even in the low rev range between 1,500 rpm and 2,500 rpm. The extremely smooth straight six-cylinder engine with its spontaneous response produces 230 kW (313 hp), thus providing an impressive display of thrust. As a result, the BMW 6 Series Gran Coupé accelerates to 100 km/h from a standing start in only 5.4 seconds and consumes an average of only 5.7 to 5.5 litres per 100 kilometres, depending on the selected wheel and tyre size.
All figures in accordance with EU test cycle, dependent upon the selected tyre format.
