The glorious RS7: For when BMW needs a good competitor against the M6. The car sounds lovely, mainly due to a 4.0 liter 560 HP V8 fed extra air with a turbo. It can go up to an electronically-limited 174 MPH. As if you would ever get it that high....wink.
If you have around $105,000 laying around, then pick up this 5-door version of the R8. If you don't, then just listen to this below.
