It's hard to tell from the shots exactly what we're looking at, but it appears to be a sportified version of the latest-generation 7 Series (codename F01), complete with quad exhaust tips and lightweight painted wheels. Of course, it could be a tuner special, a simple M-Sport appearance package or an Alpina version, but then why would the BMW badges be covered? If it is an M7, it would be a first for BMW, and could, according to speculation, derive its power from a twin-turbo V12 with over 600 horsepower. Coupled with some weight reduction, the BMW M7 could give the the Mercedes S63 AMG and Audi S8 a run for their money, of which there is plenty at stake in this stratospheric sub-segment. And as with the reported emergence of an xDrive 7 Series, the Bavarians might be growing tired of seeing their customers leave town for Stuttgart or Ingolstadt. Props to RJ for the tip!
