The BMW 540d (G31) ist the fastest currently available diesel version of the 5 series. It comes with the latest iteration of BMWs well known inline six diesel engine with two turbochargers which result in a power output of 340 HP and 700 Nm of torque in stock – so pretty respectable performance figures.

With the RaceChip GTS Black its almost as fast as its petrol sibling, the 540i. So would you consider buying one of these over a petrol variant?
