With a sultry exhaust note that rivals Joss Stone’s vocals for raw sensuality, a fluid and positive gearbox that works better the harder it’s abused, impressive all-wheel-drive grip and delightful steering, the Audi S4 is definitely fun to drive. The V8, however, feels a little bit off its game when it comes to mid-range power delivery. BMW’s new turbocharged six-cylinder in the 3 Series convertible delivers more of a thrill, but the Audi’s four-season AWD makes the S4 a better choice in northern climates.
