2010 Audi S4 — Review
This 2010 review is representative of model years 2010 to 2014.

Up until now, Audi's "S"model lineup hasn't been exactly thrilling. Sure, "S" clad autos are solid vehicles, but they've been more luxury than sport, which is really what the "S" is supposed to stand for. Enter the 2010 Audi S4. It's actually sporty, a real hoot to drive. Though less powerful than its predecessor, this slick-looking 4-door is faster and produces a relentless wave of torque that completely contradicts the manufacturer's ratings. Plus, it costs less and is 20 percent more fuel efficient. How's that for a sport sedan?
The S4 might come only one way, but the options are plenty. The big choice you'll make is between the 6-speed manual transmission or spending the extra dollars on a new 7-speed dual-clutch option. After that, you'll choose whether the sport rear differential is for you. (Estimated to come in at less than $1,000, we think it's a no-brainer — read on).
The most expensive option is Audi Drive Select, which allows the driver to push a button to affect throttle response, transmission shift points, shock stiffness and steering response. If you've opted for the sport differential, Drive Select affects the aggressiveness with which it intervenes.
Under the Hood
You can have that supercharged V6 with a 6-speed manual transmission or a new 7-speed dual-clutch transmission, which features steering-wheel-mounted paddle shifters. Ticking the dual clutch option gets you substantially faster shifts, and because of the additional gear ratio, quicker acceleration. Seven speeds equal better miles per gallon, too. With the dual-clutch transmission, the new S4 is actually 27 percent more fuel-efficient than the previous car. Audi estimates around 16/28 mpg (city/hwy).
As always, the S4 is available only with Audi's quattro all-wheel drive system. This year, the S4 sports a revised 40:60 front/rear torque split to help accentuate the car's sporting character, as well as what Audi is calling a sport differential. The system uses clutch packs to change the amount of torque delivered to each of the rear wheels, which serves to eradicate understeer by forcing power to the outer wheel. The system can send as much as 100 percent of torque (per axle) to the outside wheel, making turn-in much more apparent than many existing systems.
Unique to the S4 are sport seats, which feature integrated headrests and are available in silk nappa leather. If you're feeling particularly sporty, you can opt for that leather in two tone with contrasting stitching. European models can be fitted with Alcantara seating, but only leather will be available in the U.S.
The steering wheel and manual transmission shift boot sport contrasting stitching regardless of your choice in leather. Other notable options include heated and cooled front seats, a rear-view camera and a 505-watt Bang & Olufsen stereo system with 15 speakers.
On the Road
Engineers told us that the S4 doesn't understeer, but it took a drive on a rain-soaked test track to cement the idea. From behind the wheel, the sport differential feels as if there's an invisible finger gently pushing the rear of the car, to line it up where you wished it was. The telepathic system takes some getting used to, but once you're accustomed, it's like having a secret cheat code on the track.
Our test car was equipped with Audi Drive Select, which instantly varies the damping characteristics of the suspension. The difference between "comfort" and "dynamic" is instantly noticeable, the former being considerably less affected by undulations in the road. Admittedly, we spent most of our time in "dynamic," where the absurdly quick steering (2.2 turns lock-to-lock) worked well with the more taut suspension.
