The RS4 has the all-wheel-drive advantage, however.
Among convertibles, the Mercedes-Benz SL550 isn't quite as quick and it's only a two-seater, but it comes with a folding hardtop standard.
Jaguar's lovely XKR has scalding-hot power and a feline grace about it, as well as a fantastic six-speed automatic with paddle shifters and two very small, very unusable rear seats.
The V-10-powered BMW M6 convertible is even costlier and heftier, and it has a confusing array of interior controls.
