This acceleration test aims to reveal an undeniable reality. When it comes to cars, adding more cylinders and extra displacement to an engine will inherently result in better performance. The 750i is undoubtedly no match for the supreme BMW M760Li model. The journalists from Dutch automotive publication AutoTop were curious to find out which version is the fastest: the M760Li or the 750i? While the result may seem obvious, it is beneficial to remind that the 8-cylinder 7 Series has received a pretty impressive power boost starting with the LCI generation.

The 750i xDrive that took part in the test is put into motion by the 4.4-liter twin-turbocharged V8 engine under codename N63B44T3, which features a 90-degree V-angle and a hot inner V turbo architecture. This heavily revised powerplant developed under the N63 generation of engines was premiered on the M850i xDrive model and it is destined for the M Performance versions from the upper league. The massive 8-cylinder unit delivers a peak output of 530 PS (523 hp) and is capable of achieving a maximum torque of 750 Nm (553 lb-ft).

On the other hand, the M760Li xDrive is a quite rare model, as there are not many 12-cylinder premium luxury saloons left on the market. The range-topping BMW flagship is powered by the 6.6-liter V12 twin-turbocharged unit coded N74B66. The pre-LCI version was topping 610 PS (602 hp), whereas for the LCI M760Li, due to WLTP alignment, this engine now produces a peak output of 585 PS (577 hp). The maximum torque reaches 850 Nm (627 lb-ft).

0 to 100 km/h takes 4.0 seconds in the 750i, while the M760Li is quicker with 3.8 seconds. Top speed is electronically limited at 250 km/h (155 mph) on both models, but the 12-cylinder can get its speed limit module removed. Thus, the maximum speed of the M760Li hikes up to a staggering 305 km/h (190 mph).

The drag race battles were clearly won by the M760Li, as the V12-powered version was simply the fastest of the two in the straight line acceleration tests. While blasting through the German Autobahn on the no speed limit section, the professionally-skilled driver was able to achieve a top speed of 261 km/h (162 mph) in the 750i and a ludicrous 304 km/h (189 mph) in the M760Li. That’s another proof the V12 technology is undeniably better and more potent, if you’ve got enough cash to spend on it.
