Not every BMW has to have a 2 liter engine that revs up to 4928759487597598475 RPM and produced 600 BHP with 6 ft/lbs of torque.
The 7 series was designed to be a luxury cruiser of style and comfort, not some screaming F1 car for the people. The bigger engine will keep this car nice and smooth with even better acceleration than before. I'm not a huge fan of those roof spoilers (the should have only put one, not two =/), but I'm sure you could fix that pretty easily.
