2017 bmw M760i release in detail

BMW has officially announced the M760Li. Do not be confused however. Although bearing the M badge designation, this vehicle will more closely resemble an M performance variant such as the M235i- rather than a full fledged M car. But that does not stop the all-new M760Li from being a missile-like power house on the road. Much like the previous generation 760Li, this new generation model will feature a monstrous V12 engine with an astounding 6.6 litre displacement. BMW claims 0-100 km/hr times of 3.9 seconds. However, in considering the fact that the highly similar Alpina B7 variant 7 series accomplishes merely 3.6 seconds, with just 8 cylinders, suggests the reality of the 3.9 second M760Li’s rating begs to differ. As discussed in the article by @bmwblog, it would make sense that “BMW is only claiming those numbers to not outdo or overshadow what Alpina’s done, as the 6.6 liter twin-turbo V12 is capable of so much more power”. I’m tempted to argue that the M760Li’s 0-100km/hr rating will actually be likely closer to low-mid 3 second range on the road. Considering the fact that the M760Li achieves identical power figures to the Alpina B7, but with 4 additional cylinders, suggests to me that there is a degree of BMW’s notorious performance figure underrating at play here. The M760Li will be available for ordering beginning mid 2017. What are your thoughts on this new release? As always, here are the (initial) M760Li technical data stats:
