2018 Audi S4 review: Our expert's take


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. 


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 black. Inside, the package includes a three-spoke flat-bottom steering wheel, piano-black trim and red stitching.

Terrible experience! Thank God we saw the Carfax

Be awared on this 2018’ Audi S4! I wanted to buy it out right to the dealership! I don’t finance cars, but wow look at the Carfax report and look that on 11/23/2021 damaged reported minor damage. Damage to left front!!! Ok strike #1 .... Then 05/28/2022 Porsche Chantelly, Va reported miles 71,446 miles and then 12/15/2022 Indiana Motor Vehicle Dept Libertyville, IL odometer reading reported 90,105 miles!! In 7 months someone drove the S4 and put 18,659 miles???? strike #2.... Then look at the end of Carfax report 03/01/2023’ Structure Damage another accident!! Gish terrible... No wonder in 03/03/2023 the S4 was $30,995 and now $26,987.. I was going to buy it and give then a certified check buying out right, but No freaking way. I ask the Saleman questions about the history and then talked to the Manager and they started to stutter and I was told call Carfax report! I told the Manager thanks God we look at the Carfax Report and someone is getting screwed On this sale, but it won’t be me!!! I hope people realize you are getting screw on this S4, but sure someone will fall for it because of price..

Overall great car

This car does it all. It’s perfect for the weekend, the daily ,the snow, the rain and it’s pleasure to get in every day. Will probably own this one for the long haul.

5.0

2018 was a good year!

I have owned two earlier versions of this model and two other models from Audi and I am blown away by this car’s newer levels of luxury, fit, and finish! The newer features and amenities are quite nice too! The virtual cockpit and massaging seats are amazing! I am still learning the vehicle so I’m sure some things are being left out!
