What is it?
The BMW 520d M Sport is the fastest tax-buster model of the newly revised BMW 5 Series.
That means that it is significantly faster than the entry-level 518d, yet equals that model for emissions and fuel efficiency.
Both the 518d and 520d boast combined mpg of 62.8 and emissions of 119 grams of CO2 per kilometre driven, yet the 520d has 41 more horses, a significantly faster 0-62mph time of 8.1 seconds (versus 9.7 for the 518d) and a top speed of 145mph instead of 132mph.
With figures like that BMW saw that there was no need to have a special EfficientDynamics model any more, and killed it off earlier this year.
Dressed to look the part in M Sport guise – always the most popular 5 Series trim – and given some subtle styling tweaks and additional equipment, the BMW 520d within the face-lifted, sixth generation 5 Series range is set to be a big seller with business users and company car drivers.
