And there's already a lot of other BMW stuff on the car so switching all that to another manufacturer would be a big job indeed...
Exactly, on the new Aero 8 BMW provide:
Engine, gear boxes, differential, power steering, air conditioning, steering column/lock, steering column controls (3), instrument dispay, much of the electrical system including charging, fuel pump and gauge sender, plus bulb failure warning system - and probably more.
Modern cars are so tightly intigrated electronically that to change the engine and gear box from BMW to Jaguar would be almost like starting over. The Aeros are probably stuck with BMW power now.
