BMW is slowly but surely stealing Audi’s crown as the maker of the world’s most powerful diesel engines. They started with the M50d models and have now introduced the new BMW 750d xDrive and BMW 750Ld xDrive with a 400-hp unit — the most powerful six-cylinder diesel motor in the world.
With a maximum output of 294 kW/400 hp and peak torque of 760 Newton metres (560 lb-ft), the 3.0-litre six-cylinder in-line deisel engine in BMW 750d provides the same – or actually a little bit more – power than a conventional petrol V8 while returning much greater fuel economy ratings of 5.9 – 5.7 l/100 km [47.9 – 49.6 mpg imp], corresponding to equally low CO2 emissions of 154 – 149 g/km.
Some of the technical highlights of this engine include multi-stage turbocharging with no less than four turbos, 2,500 bar common-rail direct injection, and exhaust gas recirculation. Performance-wise, the new BMW 750d xDrive accelerates from 0 to 100 km/h / 62 mph in 4.6 seconds (the Long model is only a tenth of a second slower) and reaches an electronically limited top speed of 250 km/h (155 mph).
BMW 750d xDrive and its long version will be launched in July 2016.
