That is just a bullshit triangle by all accounts.
Nowhere is sporty, young or comfort defined.
How can a car with a higher CofG, more weight beyond the extents of it's wheels, so larger polar moment of inertia, and more weight generally by a fair margin, be compensated in the 'sporty' definition here?
My assumption is that 'sporty' is a perceptional value here. A Boxster is sporty, an M3 CSL is sporty, by that diagram, a 3.0Si is sporty, so I wonder how this new car can be as sporty as the old one.
The logic suggests the CSL didn't need to be lighter, with a lower CofG, stiffer ride, etc, to be sporty. Silly BMW
This is the marketing junk, not the reality of the situation. BMW trying to sell an SLK competitor but not lose the 'sporty' car market to the Boxster.
