The 2010 Audi S4 is technically a compact sedan, at least according to official EPA ratings, but you wouldn't know it based on the roomy interior. Compact also leads to an association with low budget, but reviews read by TheCarConnection.com show that the 2010 Audi S4 boasts a best-in-class interior and excellent build quality.
The 2010 Audi S4 has "more space inside" than the outgoing model, according to Motor Trend, thanks largely to multi-inch growth in all major dimensions. The driver and front passenger will be treated to what Left Lane News calls a "roomy front compartment," complete with "very supportive seats with built-in headrests," while those in back get "a decently spacious rear area." Road & Track isn't quite so high on the backseats, however, observing that "rear seat leg room, like many others in this midsize luxury sports sedan class, is a little tight." ConsumerGuide reviewers find "adequate headroom" for rear passengers, though overall the "legroom is tight behind taller drivers."
In addition to a comfortably spacious seating compartment, the 2010 Audi S4 offers drivers and passengers more cargo room than you'd expect. Cars.com reports that "cargo dimensions lead the segment, and a 60/40-split folding backseat, unavailable on the G35 and Lexus IS, is standard." ConsumerGuide reviewers add that the 2010 Audi S4 "sedans have a long but narrow trunk, but more actual space than most cars in this class." The trunk does feature a number of grocery-bag hooks and other organizers to help you make the most of the space. Inside the cabin, "interior storage is limited to the glovebox, door map pockets, and a small center console bin," says ConsumerGuide.
Audi's recent marketing efforts make a big deal about putting the German brand on par with the better-known luxury marquees, and Audi backs up its talk with world-class interior quality. Road & Track says that the S4's "cabin is typical Audi - exemplary in design, materials and execution," while ConsumerGuide raves that the "cabin impresses for classy design, materials, and workmanship." Edmunds asserts that Audi has a way of incorporating "supreme quality that makes more expensive cars look cheap by comparison," a technique on full display with the 2010 Audi S4. A wide range of interior trim choices add to the luxurious ambiance, and Cars.com notes that Audi offers "brushed aluminum trim or your choice of carbon fiber, wood or stainless steel."
The Audi S4 is supremely capable from a performance standpoint, but as Automobile Magazine remarks, the outrageous "speed is barely audible...barely decipherable." A lot of that is due to the excellent acoustic insulation featured on the 2010 Audi S4, which is so effective that Motor Trend claims "only under wide-open throttle does a faint hum" from the supercharged engine "emanate into the cabin."
