The "carbon core' chassis (a mix between carbon fibre and aluminium) in the new 7 series seems to work perfectly; makes the G11 so much more pleasurable (as a 7 series) to drive compared to the F01, and happens to be ~200kg lighter.
Admittedly, repairs and the expenses that revolve around repairs, at this stage, Are questionable. Can't deny that.
First time I got into an i8, the first thought which sprung to mind was how amazing it would be if BMW manages to incorporate this carbon core magic into the current/future M5/6.
Before actually driving the i8, I was expecting the car to feel stiff, so stiff, LFA stiff, in a way it would take from the feel of the car. Two corners later I realised I couldn't have been more wrong.
From what I understand, the carbon part of the carbon core concept is to benefit lightness, the aluminium part of the carbon core concept is to provide the reinforcement, flex and "feel."
Pardon me for having drifted off topic. Case in point, personally, I don't really care for BMW motorcycles but if the carbon core concept does indeed achieve the above, I welcome the idea
...if and when a carbon/aluminium frame might find itself in a Ducati superbike anyway
