Audi's compact sports sedan S4 is unchanged for 2015. It comes standard with a supercharged V6 making 333 hp and 325 lb-ft of torque. The engine is mated to a six-speed manual transmission or an optional seven-speed dual clutch automatic, both through quattro all-wheel drive. Rated fuel consumption for the S4 is 13.8 L/100 km city, 9.0 L/100 km highway for the manual and 13.0/8.5 for the automatic.
The S4 comes in two trims. The base is the S4 Progressiv, and it comes with 19-inch wheels, a sunroof, heated mirrors, automatic headlights and wipers, xenon headlights with LED daytime running lights, and Nappa leather sport seats with heat and power adjustment for the front seats. There is push button start, and Audi drive select to adjust suspension settings, throttle response and the automatic’s shift points. It has a 10-speaker stereo with satellite radio. Step up to S4 Technik and get a HomeLink garage door opener, blind spot warning, adaptive headlights, heated rear seats, a rear-view camera and a Bang & Olufsen 14-speaker stereo.
The S4 competes with the BMW 335i xDrive, Cadillac ATS, Lexus IS350 and Volvo T6. The '15 S4 is a little older than the competition, but is still impressively quick. The seven-speed is the only dual clutch automatic in the segment, and the quick shifts are a delight.
