If one turbocharger is good, surely two is better. What’s better than two? Three or even four. Clearly, BMW thought that was the case when designing the new 3.0-liter diesel six-cylinder engine found within the latest 750d.
While four turbochargers aren’t needed to produce impressive amounts of power, the engine does make the 750d quite efficient for a car of its size, sipping just 5.7 liters of diesel per 100 km (41.3mpg US on the European driving cycle). As it turns out, the four turbos also make the model quite quick off the line.
When launched properly, it takes just 4.6 seconds for the all-wheel drive diesel 7-Series to reach 100 km/h (62mph). While that’s not exactly neck-snapping speeds and bettered by some hot hatches, for a luxurious diesel-powered that weighs over 1,750 kg (3,858 lbs), it is seriously fast. That’s what 395 hp and 760 Nm (560 lb-ft of torque) can do.
Beyond the seamless power the engine provides, the all-wheel drive system helps keep the car firmly planted to the ground.
If there’s something that surprised us more than the actual performance of the car, it is the incredibly short gearing it enjoys. In fact, by the time the speedometer clocks over into triple digits, the 750d xDrive is already in fourth gear. Oh the wonders of torque.
