Our Take

from the Cars.com expert editorial team

What it is: A redesigned S4 performance sedan arrived as an early 2018 model with a 354-horsepower, 3.0-liter V-6 engine that's turbocharged instead of supercharged like the engine in its predecessor. An eight-speed automatic transmission and all-wheel drive are standard.

What’s Special

  • 18-inch wheels with standard summer tires
  • Full-LED headlights
  • Four selectable driving modes
  • Adaptive suspension available
  • Variable-ratio steering available

Here's Info on the Regular A4:

What it is: German luxury brand Audi introduced a redesigned A4 sedan last year. The styling changes were more subtle than dramatic, and the new model retained the same basic shape as its predecessor. Front- and all-wheel drive versions are available along with a manual transmission in place of the dual-clutch gearbox.  Competitors include the BMW 3 Series, Cadillac ATS, Lexus IS and Mercedes-Benz C-Class. A performance-oriented S4 variant returns for the 2018 model year. 

New for 2018

Heated front seats and S Line exterior accents are now standard. Premium Plus trims gain Audi Side Assist and Pre Sense rear safety features while the Prestige version adds lane-keeping assist, adaptive cruise control with stop-and-go capability, automatic high-beam headlights and traffic-sign-recognition capability.

A new Black Optic Plus Package includes 18-inch gloss-black wheels and all-season tires; red brake calipers; and side sills, a rear lip spoiler and side-mirror housings in gloss b...

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.
