First announced in May, BMW has now released the 518d and 520d with a new 2.0-liter diesel engine onto the European market.

In both models, the four-cylinder diesel gains 7hp while delivering up to 0.4l/100km better fuel economy and 10g/km less CO2 emissions.

On the 518d, it produces 150PS (148hp) and 360Nm (265.5 lb-ft) from 1,750-2,500 rpm allowing the sedan with a manual gearbox to complete the 0-100km/h (62mph) sprint in 9.5 seconds (8sp auto: 9.4sec) and return a combined economy of as low as 4.3l/100km, equal to 54.7mpg US and 65.7mpg UK (8sp auto: 4.2l/100km).

The 520d gets the 190PS (188hp) and 400Nm (295 lb-ft) version of the same engine with the 6sp manual saloon zipping through 100km/h (62mph) in 7.9 sec (8sp auto: 7.7 sec) and returning 4.3l/100km (54.7mpg US or 65.7mpg UK). With the 8-speed automatic, it gets 4.1l/100km combined (57.4mpg US or 68.9mpg UK).

If you want more space and practicality at the rear end, both diesel models can be had with a Touring (station wagon) body, while the 520d is also offered with BMW’s xDrive all-wheel drive system.
