I have to admit I really like the V8, too. It's a very different beast to drive but it has that initial constant acceleration which the V10 just doesn't seem to have...or have as much of if you know what I mean. However, when higher in the Rev range I much prefer how the V10 feels, I'm not 100% sure it is the engine as opposed to everything else, but the throttle response just feels more on point than in the Turbo. But then again that could just be me being used to my E60.
Saying that though, the F10 is the one to have, hands down.
