The performance of the BMW 640d speaks for itself: a fast power build-up and a low level of fuel consumption. The basis for this is provided by innovative BMW TwinPower Turbo technology, which combines CommonRail direct injection and multi-stage turbocharging with variable turbine geometry. This significantly reduces fuel consumption while, at the same time, powerfully increasing output. High torque of 630 Nm is available even at just 1,500 and 2,500 rpm. The extremely smooth-running and spontaneously responsive BMW TwinPower Turbo inline six-cylinder diesel engine has an output of 230 kW (313 hp), thereby providing impressive pulling power. In combination with other BMW EfficientDynamics measures, it was possible to additionally lower fuel consumption to just 5.7 to 5.4 litres of diesel per 100 kilometres, with CO2 emissions of 152 to 143 g/km. And acceleration to 62 mph takes just 5.4 seconds from a standing start. The BMW 640d meets the EU6 emission standard.
