BMW TwinPower Turbo diesel engines.
The BMW TwinPower Turbo technology in the diesel engines combines advanced injection technologies and fully variable output control with innovative turbocharger technology for enhanced efficiency and a more dynamic performance. All available engines feature a lightweight aluminium design and come with a maintenance-free particle filter.
The BMW TwinPower Turbo 4-cylinder diesel engine in the BMW 420d unleashes a powerful 135 kW (184 hp). With up to 380 Nm of torque, the vehicle accelerates from to 100 km/h from a standing start in 7.5 seconds (automatic transmission: 7.3 s, xDrive: 7.5 s, xDrive automatic transmission: 7.3 s) and reaches a top speed of 240 km/h (automatic transmission: 232 km/h, xDrive: 236 km/h, xDrive automatic transmission: 229 km/h). At the same time, the efficient average fuel consumption is only 4.8 to 4.7 l (automatic transmission: 4.7 to 4.6 l, xDrive: 4.9 to 4.8 l, xDrive automatic transmission: 4.9 to 4.7 l) over 100 km with CO2 emissions of 127 to 124 g/km (automatic transmission: 124 to 121 g/km, xDrive 129 to 126 g/km, xDrive automatic transmission: 128 to 124 g/km).
The BMW 430d inspires with strong performance, rapid power build-up and low consumption. Even at 1.500/min it provides a high torque of 560 Nm. The extremely smooth-running engine with its spontaneous response produces 190 kW (258 hp), thus providing an impressive display of thrust. The BMW 4 Series Coupé thus accelerates from a standing start to 100 km/h in only 5.5 seconds, has a top speed of 250 km/h (limited) and consumes on average over 100 kilometres only 5.0 to 4.9 litres of diesel with CO2 emissions of 132 to 129 g/km. (xDrive automatic transmission: 143 to 140 g/km).
Compared with these figures, the 435d xDrive automatic transmission offers 230 kW (313 hp) and a torque of 630 Nm with average fuel consumption of 5.6 to 5.4 l/km and a commendable 146 to 143 g/km of CO2 emissions. It accelerates from 0 to 100 km/h in only 4.7 seconds and has a top speed of 250 km/h (limited).
All diesel engines in the BMW 4 Series Coupé already fulfil the EU6 emission norm.
