New four-cylinder engines with BMW TwinPower Turbo technology add further talent to the line-up of petrol and diesel powerplants.

For the other diesel engines in the BMW 5 Series, autumn 2011 will bring further improvements in power, and further reductions in fuel consumption, in line with the twofold goal of BMW EfficientDynamics. The BMW 525d will get a new four-cylinder diesel engine with BMW TwinPower Turbo technology. This 2.0-litre all-aluminium unit features Variable Twin Turbo two-stage turbocharging and common-rail diesel injection with piezoelectric injectors. The new unit features reduced weight and, thanks to the VNT technology of the small turbocharger, instantaneous response. The small turbocharger comes on stream at low engine speeds, while the contribution from the larger turbocharger varies in precise response to throttle requirements.

P90077227 655x436 Premiere: BMW 520d EfficientDynamics EditionThe new BMW 525d offers a 10 kW power increase over the previous model, developing 160 kW/218 hp at 4 ,400 rpm. Peak torque of 450 Newton metres (332 lb-ft) is now available between 1,500 and 2,500 rpm. The extra agility and sprinting power is reflected in a further improvement in 0-100 km/h (62 mph) acceleration times, which now stand at 7.0 seconds for the Sedan and 7.2 seconds for the Touring model. Top speeds are 243 km/h (150.9 mph) (automatic: 239 km/h / 148.5 mph) for the new BMW 525d Sedan and 236 km/h (146.6 mph) (automatic: 233 km/h / 144.8 mph) for the BMW 525d Touring.

Average fuel consumption (as per EU test cycle, depending on tyre format) is 5.0 – 5.3 l/100 km (51.4 – 53.3 mpg imp) (automatic: 4.8 – 5.0 litres / 56.5 – 58.8 mpg imp) for the Sedan and 5.3 –5.5 litres (51.4 – 53.3 mpg imp) (automatic: 5.1 – 5.4 litres / 52.3 – 55.4 mpg imp) for the Touring model – a 20 per cent reduction over the previous models. The corresponding CO2 emissions are 132 – 138 grams (automatic: 126 – 132 grams) per kilometre for the Sedan and 138 – 145 grams (automatic: 135 – 142 grams) for the Touring model.

The 2012 BMW 520d EfficientDynamics goes on sale this fall and will be available only in Europe.
