The 190bhp variant of the new four-cylinder power unit, meanwhile, boosts peak torque by 20 Newton metres to 400 Nm. This version of the engine is fitted in the BMW 520d Sedan as well as the BMW 520d xDrive Sedan and BMW 520d xDrive Touring models with intelligent all-wheel drive. The likewise updated eight-speed Steptronic transmission is available for the rear-wheel-drive models as an option in place of the standard six-speed manual gearbox, and included as standard on the all-wheel-drive models.
These new gains in fuel economy represent further evidence of the effectiveness of the ongoing development work – focusing on the optimization of combustion engines and other components – under the BMW EfficientDynamics banner. The current generation of the BMW 5-Series has set the pace in its class in terms of economy and driving pleasure from day one, thanks to extensive use of BMW EfficientDynamics innovations, such as BMW TwinPower Turbo technology, the eight-speed Steptronic transmission, Electric Power Steering, Brake Energy Regeneration and numerous other measures.
