BMW 335i: The new 335i isn't quite as sharp as the previous model, but it's still a very capable sport sedan. This is the S4's principal competitor.
Mercedes-Benz C63 AMG: The C63 is much more expensive than the S4 if you look at base prices, but it's easy for a well-optioned S4 to creep up toward AMG territory. If you ask us, the base C63 is more appealing than a fully loaded S4.
Infiniti G37: Although the burly Infiniti lacks the S4's refinement, it makes almost the same horsepower without the aid of forced induction. Worth considering if the price differential is significant.
