Overview

The Audi S5—the A5’s sportier, more powerful sibling—gets a total makeover for 2018, with a new exterior design, an updated interior, a new powertrain, and even more driver-assistance technologies. The 2018 S5 is available in coupe or convertible form, with only minor differences between the two.
The new S5 displays a wider architectural design with a longer, flatter Singleframe grille and longer hood lines. The car’s stance is lower as well, with xenon plus headlights with daytime running lights up front and LED taillights with dynamic turn signals at the rear. Its profile shows off 18-inch Audi Sport 5-double-spoke-star wheels with summer performance tires, which can be upgraded to 19-inch 5-spoke-Cavo color-contrasting wheels.
The S5’s cabin gets a plethora of luxurious appointments, from a 3-spoke multifunction flat-bottom sport steering wheel with paddle shifters to S sport seats with contrast diamond stitching, pneumatic side bolsters, and a massage function. Other standard features include 3-zone automatic climate control with diffuser air vents, a panoramic sunroof, ambient LED lighting, aluminum matte brushed inlays, and a height-adjustable folding and sliding center armrest.
The convertible S5 variant is almost identical its coupe sibling, with a soft top that operates at the press of a button and folds into a tray beneath the luggage compartment. It works at speeds up to 31 mph, opening in 15 seconds and closing in 18. This year sees the debut of safety-belt microphones exclusive to the convertible, making voice commands more easily understood when the top is down.
For 2018, the S5 is outfitted with an all-new 3.0-liter TFSI 6-cylinder engine mated to an 8-speed Tiptronic automatic transmission for an output of 354 hp and 369 lb-ft of torque. The S5 comes with standard quattro all-wheel drive (AWD) and can reach 60 mph in 4.4 seconds (or 4.8 seconds for the convertible variant). Its revised suspension system delivers precise steering and handling for a sporty yet comfortable ride, and drivers can choose between Comfort, Auto, Dynamic, and Individual drive modes to adjust the shift points, steering, and optional damper control and adaptive cruise control. Available dynamic steering further enhances the drive with a variable steering ratio that adjusts depending on the speed and drive mode. For an even more dynamic driving experience, the S5 offers an S Sport package with red brake calipers, a sport adaptive damping suspension, and a sport rear differential.
The new Audi virtual cockpit is now available for the 2018 S5 and adds a 12.3-inch color display screen with Google Earth-based navigation. The standard MMI infotainment system comes with Apple CarPlay and Android Auto capability, and available options include a full-color head-up display, an upgraded 19-speaker 755-watt Bang & Olufsen sound system, and MMI touch with handwriting recognition and a unique function-key layout with 2 touch-keys. The ultimate in connectivity is provided through Audi connect, a subscription service that offers traffic information, weather updates, fuel prices, read-aloud headlines, and even Twitter alerts. Audi connect also comes with available safety features like automatic crash notification, manual emergency call, stolen-vehicle locator, online roadside assistance, and service notifications.
Safety also gets an upgrade for 2018, with more advanced driver-assistance technologies like Audi “pre sense basic” now standard on the S5. This system prepares the vehicle for an imminent collision by closing the side windows and panoramic sunroof and tightening the seat belts. The Audi “pre sense city” system, operating at speeds up to 52 mph, detects vehicles and pedestrians in the surrounding area and will initiate full braking if a collision is anticipated. Available safety features include rear cross-traffic assist, adaptive cruise control with stop-and-go and traffic-jam assist, traffic-sign recognition, and lane-departure warning.

Is the 2018 Audi S5 a good car?
Yes — the 2018 Audi S5 earns a 4.9/5 user rating, which points to very strong owner satisfaction. Owners consistently praise its powerful performance, sleek styling, and advanced technology features, and many also like the convertible top and smooth ride.

Is the 2018 Audi S5 reliable?
Owners rate it 4.9/5, a strong signal of long-term satisfaction.
The user feedback also points to a car that owners feel good about living with over time, especially when it comes to performance and everyday drivability. For used buyers, the main long-term ownership risk is making sure the specific car you choose has been maintained well and still feels tight, since condition can vary a lot from one listing to another.
What should I look for when buying a used 2018 Audi S5?
At 67.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should start with a vehicle history report so you can separate clean examples from cars with prior damage. After that, prioritize a thorough inspection of body condition, panel alignment, and any signs of repair work, since those details matter more when a meaningful share of listings has accident history. It also helps to focus on how the car feels in person, especially if you want the convertible experience and smooth ride owners tend to value.
Is now a good time to buy a used 2018 Audi S5?
This looks like a moderate, selective buyer’s market, so you can shop carefully without feeling rushed.
- Deal availability: 39.2% of listings are priced as good or great deals.
- Inventory: There are 102 listings available.
- Price trend: Prices have softened 7.84% compared with last year.
- Clean inventory: 67.6% of listings are accident-free.
If you find a listing below $23,598, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2018 Audi S5's resale value?
The current average of $25,300 sits slightly below last year's $27,452.
That price movement suggests the market has cooled a bit, which can make resale timing more important if you plan to sell later. If you buy at a strong price and keep the car in good condition, you give yourself a better chance of limiting depreciation. Demand should also stay supported by the model's strong owner satisfaction and premium appeal.
Vehicles with strong owner satisfaction ratings, like this model year's 4.9/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2018 Audi S5 or consider a different year?
If you're weighing the 2018 against nearby model years, here's how to think about it:
