Watch out, Mercedes and Audi.
The BMW 7 Series will always be one of the mavens of four-door luxury cars for executives, along with the Mercedes-Benz S-Class and Audi A8. However, it seems that BMW found a way to defeat its German rivals in the power department. The new top-of-the-line 760Li will be powered by a de-tuned version of the 6.6-liter twin-turbo Rolls-Royce V12 engine used in the absolutely gorgeous Wraith. Every 7 Series (except the very first one) had a V12 engine in its lineup. It would be a crime for the new version not to have one.
It would make sense for the 760Li to have the heart of the Rolls-Royce because of its smooth power delivery. Oh, it also makes sense because BMW provides the engines in the first place! Also, it's completely badass. However, don’t expect the new engine to produce big numbers like what you get on a 632-hp Wraith; think more towards 600-hp at most. That’s enough power to topple the S63 AMG, S65 AMG and the Audi S8. The V12 engine will be mated to the 8HP90 gearbox that uses satellite navigation to change gears to match road conditions ahead. All these things, especially that engine, will make the new 7 Series pretty much unstoppable.
