But the Rapide does try to tailor to the sporty crowd. It is marketed as such. It is significantly lighter than rivals like the various Bentley and the Rolls Royce four-doors, and it was tested on the Nordschleife. It performs favorably compared to the BMW M5, and people have compared the two.

I don't think it's fair to compare the Model S with the M3. The M3 (well, the M4) aims to be a compact executive. In terms of wheelbase, the Model S is much closer to the M5 and the Rapide.
