Which S5 does Edmunds recommend?

The Premium Plus trim gets our recommendation since you can pick and choose options more selectively than you can otherwise on the fully loaded Prestige. We do suggest adding the S Sport package to get the adaptive suspension as well as the Navigation package for the larger screen and virtual instrument panel.

Edmunds' Expert Review

Overall rating

After a decade, the Audi S5 has finally received a full redesign and the wait was well worth it. This new model builds on its predecessor's best traits, including sleek styling, a refined interior and spirited driving dynamics, and takes them to all-new levels.

In almost every metric, this latest coupe is a prime example of how to do it right. It's a blast to drive, yet it doesn't sacrifice luxury and comfort in the process. We're also impressed with the S5's latest batch of technology features. Compared to rival sport coupes such as the BMW 4 Series and Mercedes C-Class, the 2018 Audi S5 rises to the top.

2018 Audi S5 models

The 2018 Audi S5 is a four-passenger luxury sport coupe that is a high-performance variant of the A5 coupe. It is available in either Premium Plus or Prestige trim levels. Both are powered by a turbocharged 3.0-liter V6 (354 horsepower, 369 pound-feet of torque). All-wheel drive is standard, as is an eight-speed automatic transmission.

Standard features for the Premium Plus trim include 18-inch wheels with summer performance tires, automatic LED headlights, automatic wipers, power-folding mirrors with heating, a panoramic sunroof, front and rear parking sensors, keyless entry and ignition, tri-zone automatic climate control, leather upholstery, power front seats (with heating and massage functions), driver-seat memory settings, 40/20/40-split folding rear seats, auto-dimming mirrors and interior ambient lighting.

On the technology front, you also get Bluetooth, a 7-inch infotainment display, a rearview camera, a Wi-Fi hotspot, remote control via a smartphone app, Apple CarPlay and Android Auto smartphone integration, and a 10-speaker audio system with a CD player, satellite and HD radio, two USB ports and dual SD card slots. Additional safety features include low-speed forward collision warning and mitigation, blind-spot monitoring with rear cross-traffic alert, and Audi Connect Care emergency telematics.

The Prestige trim includes all of the above, along with a virtual instrument panel display, streaming internet radio apps, remote vehicle monitoring via a smartphone app, a bigger 8.3-inch infotainment display, a navigation system, a tracepad feature for infotainment input, a top-down parking camera system and a 19-speaker Bang & Olufsen premium surround-sound system. All of these items are available as options on the Premium Plus trim.

Other options include the S Sport package (red brake calipers, adaptive suspension dampers and sport rear differential); the Warm Weather package (ventilated front seats and extended premium leather upholstery); an adaptive steering system; and a heated steering wheel. The Prestige trim is eligible for the Driver Assistance package that adds traffic-adaptive cruise control, a traffic sign reader, lane departure warning and intervention, and automatic high beams.

Trim tested

Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our First Drive of the 2018 Audi S5 Prestige Coupe (turbo 3.0L V6 | 8-speed automatic | AWD).

Driving

The 2018 Audi S5 is at the top of the class when it comes to driver engagement and performance. It's a blast to drive on a twisty road yet well-mannered in everyday situations.

Acceleration

There's a brief hesitation when you hit the gas from a stop. But after that acceleration is incredibly smooth. Upshifts are almost imperceptible. It's deceptive how quickly this car gets up to speed, requiring the driver to show high levels of restraint.

Braking

The pedal is appropriately firm for a performance vehicle like this. After flogging it repeatedly on a challenging mountain pass, we never experienced any fade or softening of the pedal. Under normal conditions, the brakes are easy to modulate and bring the car to a smooth stop.

Steering

Steering effort feels right in each drive mode (lighter in Comfort, heavier in Dynamic), but there's little feedback to tell the driver when grip is at the limit. The optional adaptive steering feels awkward when accelerating and turning from a stop.

Handling

The S5 has impressive roadholding capabilities. It easily navigates through sharp turns at speeds that would overwhelm lesser vehicles. The all-wheel-drive system deftly supplies power to specific wheels to aid the car's handling balance around turns.

Drivability

The initial hesitation is a bit of a letdown, but it's nowhere close to being a deal breaker. The same holds true for the automatic engine stop-start function, but this is typical in most competitors. Otherwise, the S5 is a joy to drive in any condition.

Interior

The S5's cabin is a wonderful expression of modern, understated luxury. The materials quality is high, and the smart layout of controls makes operation easy and distraction-free.

Ease of use

There are only buttons for essential controls. You operate everything else through the MMI infotainment system. The simple design and logical placement and grouping of buttons mean you'll rarely have to look down to use them. This is an example of how it's done right.

Getting in/getting out

The long doors make front-seat access effortless, and the seat-belt presenter eliminates the need to reach back. Access to the rear seats is typical for the class, which means it requires an inelegant crouch and side shimmy to get past the roof and front seat.

Driving position

The driver's seat has numerous power adjustments and a wide range of movement. There's extendable thigh support, too. Drivers of just about any size and shape should be able to find their optimal position.

Roominess

As you'd expect from a performance coupe, the S5's cockpit has a sporty wraparound feel, but it never feels tight or confining. Backseat space is cramped for adults, but smaller passengers should be fine back there.

Visibility

The roof pillars are moderately thick, which is typical for any car today. But they don't obstruct your outward view much, and the optional top-down camera system takes away any guesswork in tight parking spaces. Mirrors offer good coverage, too.

Quality

Even among other great luxury sport coupes, the Audi S5 stands out. All materials are high-quality, and buttons have an identical and precise click. At the same time, interior components have a durable heft.

Utility

The S5 is about average for interior storage but gets better marks when it comes to trunk space and the convenience items associated with it. The trunk is bigger than the exterior size suggests, though it's not much bigger than average for the class.

Small-item storage

There's not an abundance of bins or pockets, and they are not particularly large. They offer just enough space for your personal items and not much more.

Cargo space

The trunk has a 11.6-cubic-foot capacity. That's not great, but it's roomy enough for most daily cargo-hauling tasks. A flat load floor, remote seatback releases, anchor points and retractable bag hangers garner it more points for convenience.

Technology

The Audi S5 has a lot of high-tech features and makes them easy to use. The virtual instrument panel is particularly good with configurable sections and clear graphics in any light. The MMI infotainment system's evolution keeps it among our favorites.

Audio & navigation

The optional Bang & Olufsen sound system delivers powerful audio with excellent clarity. The navigation is packed with features and is easy to operate, particularly with the tracepad and voice commands. The MMI system continues to get high marks.

Smartphone integration

Apple CarPlay and Android Auto are standard equipment on all S5 models. For audio control, Apple CarPlay is preferable to Audi's MMI, but it's awkward to control with the dial rather than a touchscreen.

Driver aids

The forward collision warning system is well tuned without being overly sensitive in traffic. The blind-spot monitoring is subtle enough to not be a distraction. Stability and traction control are also smartly tuned to give you just enough leeway to have fun but not enough to get you in trouble.

Voice control

Voice recognition is excellent whether through MMI or Apple CarPlay. Apple CarPlay is a bit easier to use with plain speech but does require an internet connection.

Rock,05/17/2018
Prestige quattro 2dr Convertible AWD (3.0L 6cyl Turbo 8A)
Had an 06 A5 Premium convertible. Gorgeous and fun to drive but not enough umph! This one on the other hand has the HP my 06 Mustang GT had after some mods to the GT and I doubt the Mustang could outrun it. That sayin something folks! It’s a prestige and I know I know that’s taking it little too far if all your after is horsepower...but I don’t regret it. Took it on a 2000 mile trip and was quite surprised about the mpg even doing 80-90 mph on the interstate. How’s 31 mpg sound? Speaking of sound, WOW! It will take you awhile to learn all the features but you’ll enjoy the process and what Audi has done. Drawbacks? The auto stop engine feature when idling maybe but the feature functions flawlessly. This is a 10 year car for us. Wife drives it more than I do and loves it! It’s white with the red interior so kinda on the feminine side but she looks awesome in it!
Audi has done it Right! (Again)

Prestige quattro 2dr Convertible AWD (3.0L 6cyl Turbo 8A)
The newly redesigned Audi S5 is a absolute blast to drive. Its so good that i traded my 2017 S6 in for it!
Really nice car with a minor gripe
Scotty Mac,11/06/2019
Prestige quattro 2dr Convertible AWD (3.0L 6cyl Turbo 8A)
First off, let me say that a really like this car. Lots of options, comfortable. and quick. I like the interior and adjustable options (suspension, drivetrain, exhaust, etc.). For a heavy car, it really sticks in the turns. I own a 2002 M roadster and the audi feels like it can stay with it on my favorite cambered on ramp all day long. It probably has more to do with the driver than the car, but I feel like the awd and sport diff really gives you confidence to stick a 4K lb car in the turns. Very quiet for a convertible with the top up. I like the knock down back seats for adding storage to the convertible's reduced trunk space. Now for the gripe: The turbo lag is really unacceptable for a car in this price range - particularly coming out of VW group which has been doing turbos for a while. The previous gen supercharged motor had less output, but no lag. There are ways of getting around it by leaning into the throttle rather than hitting WOT from idle. However, there are times when you are pulling out into traffic when that's exactly what is needed and that hesitation is not a good feeling. Other minor issues: Also, do not like the auto dimming mirrors all around. I wish there was an off option if possible. Night time and early morning driving dims out the rear view to a point where you can only see headlights and not make out what type of vehicle it is. The dimming is not really needed in the side mirrors. A couple of small plastic trim pieces (seat belt hanger rack, rear seat wind block pegs) broke and they all seems to be around $80 for a $2-$10 part. I guess that's what you get expect in this price range. If buying used, I would definitely recommend an extended warranty. I'm not saying things are going to go bad, but this car has a lot of expensive sounding options if repairs are needed. The convertible top actions with the windows lowering and hatch mechanism alone would warrant it, not to mention the seat massagers and LCD dashboard. The stereo sounds awesome, but I'm not even sure where it is located. Its not like you are going to put in an aftermarket unit in this car. I don't want to give the impression that I don't like this car. Its one of the nicest cars I have owned - thus the 4 star rating. I just thought I would point out the shortcomings (all cars have them) that I have noticed during my ownership. I suppose they will come out with an RS cab that I'll start coveting next.....
Fun car to drive if works
AG,07/02/2018
Premium Plus quattro 2dr Convertible AWD (3.0L 6cyl Turbo 8A)
Had fun with my S5 cabrio for 15 days. Day 16 around 600miles transmission broke, barely made it home. Waiting for almost a week now to have it replaced. Regret about buying it, should have leased it instead.

Should I lease or buy a 2018 Audi S5?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
