report that this test vehicle has the standard S55 engine (317Kw), which we can speculate won't hold true for the production car, is it possible this car gets the water injected S55? In other words, could this be the sequel to the CRT - an M3 with the GTS engine and a swanky interior?
One big advantage would be that this would allow BMW to be liberal with the pricing ($100k+ USD) and avoid any direct, feature-for-feature comparisons to the M4 CS.
