Audi A5 (B9)

Audi A5 (B9)

Model Years Produced: 2018 to Current


Like the 4-Series is to BMW’s 3-Series, the A5 is Audi’s more stylish version of the A4 sedan. Unlike the 4-Series, the A5’s design doesn’t make people who see it physically ill.

The A5 is available in three different body styles: coupe, convertible (called the Cabriolet), and a liftback/hatchback (called the Sportback). The Sportback has four doors rather than two and also is slightly longer-wheelbase than the other two body styles, providing some extra rear legroom.

The S5 and RS5 may be slightly down on power compared to the M440i and M4, respectively, nevermind the M4 Competition…but what they lack in straight-line grunt, they make up for in livability and one of the most clean interior designs to grace a car. The S5 is also significantly cheaper than a similarly-specced M440i, with the coupe coming in nearly $6000 under an M440i xDrive Coupe and the Cabriolet nearly $5000 under an M440i xDrive Convertible – leaving enough room to jump up to the “Premium Plus” trim level and tick a few option boxes.

Overall, the S5 and RS5 are excellent alternatives to their Bavarian competitors, able to serve as comfortable cruisers with enough of a sporty edge to sate the desires of most auto enthusiasts who can afford them. When outfitted with the Black Optics package, they certainly look the part, too.

Primary Criticisms




  • Ventilated seats are an additional cost on the S5, and they require deleting the S sport seats (which means deleting the quilted/diamond leather and the massage function); they’re also only available in black. Ventilated seats are not available at all on the RS5.
  • Dynamic Steering option lacks steering feel.
  • S5 isn’t as quick as the BMW M340i/M440i or Mercedes C43.

The S5 receives a corporate VW 3.0L turbocharged 90-degree V6 with a “hot-V” setup for improved efficiency. Thanks to the engine layout, throttle response is great, and there is very little perceived turbo lag. All S5s come standard with Audi’s “quattro” AWD system which includes a mechanical limited-slip differential, and an electronic LSD is available as an option as part of the S Sport package.

The Premium Plus trim level is the sweet spot for those looking for a luxury-sports car.

The RS5 shares its 2.9L twin-turbocharged V6 with a number of other products in the VAG family including the Audi S7 and the Porsche Panamera. Unlike the S5, the RS5 does not have different trim levels and therefore requires selecting the specific options you want.

Unlike the A5 and S5, the RS5 is sadly not available as a convertible.
