Thanks: Öztorun Oto In the new BMW 740d xDrive, an extensively updated combustion engine teams up with the latest 48V mild hybrid technology featuring an electric motor integrated into the eight-speed Steptronic transmission. The result is maximum output of 220 kW/300 hp (generated by the combination of the engine with up to 210 kW/286 hp and the integrated electric motor with up to 13 kW/18 hp) and peak torque von 670 Nm / 494 lb-ft (generated by the combination of the engine with up to 650 Nm (479 lb-ft) and the integrated electric motor with up to 200 Nm (147 lb-ft)). The six-cylinder in-line diesel powering the BMW 740d xDrive has new steel pistons which enable particularly high combustion pressure and enrich the engine’s soundtrack. The effectiveness of the oil separation process has also been enhanced compared with the predecessor engine. The new common-rail direct injection system now works with solenoid valve injectors which provide up to 12 injections per power stroke with maximum pressure of 2,500 bar. The latest generation of mild-hybrid technology ensures the additional power comes on tap with particular immediacy and the level of recuperation is high, so as to improve efficiency. The electric motor is integrated – together with its power electronics – into the housing of the eight-speed Steptronic transmission, where it also assumes the role of a crankshaft-driven starter generator. The rapid power delivery of the electrified drive system enables acceleration from 0 to 100 km/h (62 mph) in 5.8 seconds. Added to which, the high-precision interplay between the combustion engine and electric motor enhances the efficiency and smoothness of the drive system, making it ideally suited for service in the new BMW 7 Series.
