The top brass from Munich have officially shot down any possibility for a future BMW 7-Series wearing an M badge. That role of a high performance limousine has traditionally been left to Alpina. But apparently, just the other day, spy photographers caught this stretched Bimmer that reportedly "really seems like an M version of the 7-Series." So the question is, what was it?

BMW representatives have said that the M image doesn’t fit in a limousine model, but just a short while ago, they said the same thing about the X5 SUV, a vehicle that is now part of their lineup. So, what’s the true story behind this camouflaged 7-Series.

A closer look at the prototype seen in the photo reveals plenty of M characteristics; like the larger big mouth front bumper and what could be a hood made from lightweight aluminum. If this is the case, and there is going to be an M7, it will most likely be powered by the same twin-turbo eight cylinder found in the BMW X6 M, with an expected output somewhere between 500 and 550 HP.
