What Is the 2015 Audi S4?

The 2015 Audi S4 is a four-door luxury sports sedan based on the 2015 Audi A4, which is covered separately on Cars.com. It comes in one trim level, 3.0T Premium Plus, with Audi's Quattro all-wheel drive, a 3.0-liter V-6 engine and a standard six-speed manual transmission. The 2015 Audi S4 competes with luxury sports sedans like the BMW 335i, the Infiniti Q50 and the Lexus IS 350.

What's New on the 2015 Audi S4?

For 2015, Audi released a Nogaro Blue Special Edition that features 19-inch wheels, sport front seats, black leather upholstery with blue Alcantara inserts, and aluminum trim.

How Does the 2015 Audi S4 Compare to Other Luxury Sports Sedans?

While the S4 isn't as efficient as the BMW 3 Series or Lexus IS 350, its 3.0-liter V-6 engine is more powerful than its competitors'. Standard all-wheel drive on the S4 also puts it ahead of both the BMW and Lexus, which have standard rear-wheel drive. It'll cost you, though; the 2015 Audi S4's starting price is higher than either of those competitors.

What Features in the 2015 Audi S4 Are Most important?

The S4's supercharged 3.0-liter V-6 engine generates 333 horsepower. It comes with standard all-wheel drive with a 40/60 front/rear torque distribution. You can choose a six-speed manual transmission or seven-speed dual-clutch automatic with steering-wheel paddle shifters. A sport mechanical rear differential is also available.

The 2015 Audi S4 comes standard with leather and Alcantara upholstery, Bluetooth connectivity, keyless entry and engine start, sport seats and 18-inch wheels. It also gets  standard brushed aluminum trim, Xenon high-intensity-discharge headlights with LED daytime running lights, a power moonroof and auto-dimming heated side mirrors. It's available with 19-inch wheels, carbon fiber or aluminum and wood trim, a Bang & Olufsen premium stereo, navigation, a backup camera and Nappa leather upholstery.

As is required in every new car, the 2015 Audi S4 comes with front airbags, antilock brakes and an electronic stability system. It also comes with standard side-impact airbags for the front seats and side curtain airbags. Rear-seat side-impact airbags are available.

Should I Buy the 2015 Audi S4?

The 2015 Audi S4 boasts a quality, luxurious interior with a premium stereo, and its powerful performance makes for a thrilling ride. It's worth a test drive if you're looking for a comfortable, fun luxury sports sedan.

If you're looking for an efficient sports sedan, though, you'd be better served by another choice. What's more, the Audi S4's backseat is tight, and the lack of a standard limited-slip differential is a notable oversight.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
