Audi has wrapped up and extensive overhaul of its entire range of S models, bringing each and every model up to date with the latest styling, features and powertrains to compete with the sporty offerings coming from the likes of BMW and Mercedes-Benz - with the S4 being the first and smallest of the bunch to get the refresh treatment.
Based on the more sedate A4 sedan, the S4 ratchets up the performance quotient with a 333 horsepower, 325 lb-ft or torque TFSI V6 engine that yields a zero-to-60 mpg time of five seconds and an electronically limited top speed of 155 miles per hour.
A4 and S4 differences
While the changes between the second to most recent and most recent A4 models may require a close inspection for the average person to spot, the differences between the more civilian A4 and more sporty S4 models can be spotted much more easily. That is thanks to a much more aggressive front fascia, which includes a unique details throughout, ranging from more detailed foglamps housing, to a metallic-trimmed grille, to S4 badging, to unique headlamp housings in the front.
From the side, notice unique, more sporty wheels, mounted outside larger, high-performance calipers and rotors to help bring the performance-minded car to a halt.
Continuing to the rear, the S4 gains a unique rear fascia and badging that will let more pedestrian vehicles know exactly why they are viewing the back – and not the front – of the S4.
Inside, the S4 gains unique black and gray contrasting leather accents throughout, along with S-gauges, door sills and badging. There is no mistaking sitting in an S4 model over the standard counterpart.
In the U.S., buyers can choose between two trim levels for the S4: Premium Plus or Prestige, along with the choice of either a standard six-speed manual transmission of optional S tronic automatic.
Sticking with the "base" Premium Plus model will yield 18-inch five-parallel spoke S-design wheels, Audi music interface with iPod cable, xenon plus front lighting with LED daytime running lamps and taillamps, auto-dimming mirrors, brushed aluminum decorative inlays, heated and 12-way power front seats, leather and Alcantara S sport seats throughout and a power sunroof.
Opt for the Prestige and you can add to or substitute to the Premium Plus model's equipment with 19-inch five-spoke wheels, Audi adaptive light, Audi advanced key, Audi MMI Navigation Plus, Audi side assist, a 14-speaker, 505-watt Bang & Olufsen sound system, stitched Fine Nappa leather armrests for the doors and rear acoustic parking sensors.
Dimensions match those of the standard A4 model, with the S4 Sedan measuring 15.49 feet in length, with a 9.22 foot wheelbase and a six-foot width – with a 4.63-foot height.
Key Competitors
The S4 is aimed at the competition's mid-grade small sedans that slot between the base-engine cars and the performance models. These include the Mercedes-Benz C350, the BMW 335i and the Infiniti G37.
