The German automaker has recently announced the availability of its new 750d xDrive and 750Ld xDrive, equipped with a diesel engine capable of developing 394 horsepower (400 PS / 294 kW) and 560 pound-feet (760 Nm) of torque.
Both models can take pride in packing the world’s most powerful diesel engine with a six cylinders configuration and will become available across dealerships in Europe this July. The world’s most powerful, the 3.0-liter TwinPower Turbo six-cylinder engine is rated at 394 hp and 760 Nm of torque, linked to an eight-speed Steptronic transmission and an all-wheel drive system. The power credentials deliver astonishing performance as well: 4.6 seconds are needed for the usual 62 mph (100 km/h) sprint and the top speed has been electronically capped at 155 mph (250 km/h) when discussing the 750d xDrive. The bigger and heavier 750Ld xDrive is just behind with 4.7 seconds and the same limited maximum speed of 155 mph.
The new engine, which now packs four turbochargers, is more powerful than the previous tri-turbo iteration but still manages to be more fuel-efficient. The latter and its corresponding Co2 emissions have been reduced by 11 percent. That means both 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. The company says the four turbochargers with multi-stage turbocharging technology “enable boost pressure to be built up even more quickly at lower engine speeds and therefore prompts incredibly swift responses to throttle applications from idle.”
