BMW has given its 518d and the 520d models mild power changes, which will be reflected from September this year, for the international markets.

The strong-selling sedan and estate from BMW will get a new-generation 2.0-litre four-cylinder turbocharged diesel engine that is claimed improve performance and fuel economy.

The B47 designated unit, first unveiled in the facelifted BMW X3, uses the latest common rail injector technology, and will power the reworked 518d with 148bhp and 40.8kgm of torque – an increase of 7bhp and 2.07kgm on the existing model. On the other hand, the BMW 520d’s reserves have been boosted by 6bhp to 187bhp, with torque increasing by a similar 2.07kgm to the same 40.8kgm as the 518d.

The new engine will be mated to a reworked version of BMW’s eight-speed automatic gearbox, which is claimed to provide further fuel efficiency. However, a six-speed manual ‘box remains standard on both the models. There is no news as of now if these engines will come to India.
