BMW has officially unveiled the all-new 750d xDrive and 750Ld xDrive. Both versions are set to go on sale in July and are equipped with the world’s most powerful six-cylinder diesel engine. 

We are talking about a 3.0 liter TwinPower Turbo six-cylinder engine that can deliver 400 horsepower at 4,400 rpm. The engine serves up over 450 Newton meters (332 lb-ft) of torque at just 1,000 rpm and puts its maximum 760 Newton meters (560 lb-ft) on tap between 2,000 and 3,000 rpm. 

The engine is matted to an eight-speed Steptronic transmission and an all-wheel drive system. As a result, the BMW 750d xDrive will run from stand still to 100 km/h in just 4.6 seconds, while the top speed is clocked at 250 km/h. 

Despite being more powerful than the previous tri-turbo engine, the new engine has lower CO2 emissions and a better fuel consumption. To put that in figures, the models average between 39.8 and 41.2 miles per gallon (47.9–49.6 mpg imp / 5.7-5.9 L/100km) with CO2 emissions between 149-154 grams per kilometer.
