2021 Audi A5 Convertible Review: Drop-Top Elitism

by Deiondre van der Merwe

Based on the A4 sedan, but with fewer doors and the roof chopped off, the 2021 Audi A5 Convertible is a sumptuous drop-top powered by an uprated 2.0-liter turbocharged four-pot for the new year. The powerplant sends 261 horsepower to all four wheels as standard via Audi's quattro system. One can expect a spacious cabin swathed in premium materials regardless of the trim you choose: just one of the factors that ensure the Audi A5 cabriolet is an undeniably strong contender in the segment. This is despite healthy competition from the Mercedes-Benz C-Class Convertible and the all-new BMW 4 Series Convertible. It may not be the sportiest, but what it lacks in thrills it makes up for in comfort. If you wondered if the A5 Convertible deserves a spot on your shortlist it does. In fact, it belongs very near to the top.

2021 Audi A5 Convertible Changes: 🚙What’s the difference vs 2020 A5 Convertible?

For 2021, the Audi A5 Convertible has received quite a number of updates, the most important being the addition of a 12-volt mild-hybrid system to the four-pot engine. Along with the electric assistance is an increase of 13 horsepower over the previous model. Lane departure warning is now standard on the base model, and the Premium Plus spec welcomes adaptive cruise control, active lane assist, a hands-on detection steering wheel, and a top-view camera system.

Pros and Cons

  • Powerful four-cylinder turbo engine
  • Great fuel economy

Audi A5 Convertible Exterior: No Hardtop Here

The Audi A5 Convertible is one of the most attractive options in this segment, and it's been breaking even more necks since its recent facelift. The front end's aggressive appearance is attributable to the large honeycomb Singleframe grille with razor-sharp LED headlights located on either side. Elegant lines direct us to the cabriolet's rear, where a set of chrome exhaust outlets mold perfectly into the diffuser. A pair of slim LED taillights include dynamic rear indicators. All three trim levels sit on a set of 18-inch V-spoke wheels as standard. There is no option of a hardtop for the Audi A5 Convertible, though, with the A5 wearing a standard black folding soft-top. With a clear focus on luxury over performance, there is no S line kit available for the A5 drop-top, but a range of paint colors is available to tailor the overall look.

The new Audi A5 Convertible is a similar size to its chief rivals in terms of exterior dimensions, with a length of 184.9 inches and a width of 79.8 inches with the mirrors included. Its low-slung profile is achieved by combining these measurements with a 54.4-inch height. All models have a 3,979-pound curb weight.

Engine and Transmission

Previously, the turbocharged 2.0-liter four-cylinder put out 248 hp and 273 lb-ft of torque, but the 2021 A5 Convertible has changed for the better. The engine is still mated to a seven-speed dual-clutch automatic transmission with no manual option available. In our 2020 review, we felt the A5 Convertible provided more than ample levels of performance, so the small bump in power to 261 horses is a welcome improvement. The extra power is thanks to the new 12-volt mild hybrid system. In terms of outputs, it's on par with its rivals from BMW and Mercedes-Benz. The cabrio makes the run from 0-60 mph in around six seconds according to Audi.

Handling and Driving Impressions

The Audi A5 Convertible's quattro system is highly competent, meaning that you can put your foot down with loads of confidence regardless of the road conditions. This is a good thing for safety, but it may be a downfall for those who frequently take a stroll on the wild side. Of course, it's not lazy by any measure - it's perfect for a long drive on a sunny afternoon, but the lack of structural rigidity means it isn't quite as composed as the hardtop equivalent. The steering is excellently weighted and sharp, making it rather fun to chuck into corners if you know what you're doing. As for comfort levels, the A5 offers delightfully smooth power delivery, and the ride quality is great, too, provided you don't venture off the beaten track.

Audi A5 Cabrio Gas Mileage

The A5 Convertible is a rather light sipper, meaning that you can enjoy quite a bit of power without wondering if you're racking up a monstrous fuel bill. While the 2021 model's EPA estimates haven't been released, the 2020 models returned EPA estimates of 23/31/26 mpg. The Audi is on par with the 2020 BMW 430i xDrive convertible's figures of 22/32/26 mpg, but is more frugal than the Mercedes-Benz C300 4MATIC's 21/29/24 mpg estimates. With the addition of a mild hybrid system for the new year, we expect these figures to improve further. When the 15.3-gallon tank is full, the A5 will manage a range of approximately 398 miles.

Seating and Interior Space

One of the Audi A5's biggest edges in the segment is its immaculate interior. Every inch is covered in top-tier soft-touch materials, and not a trace of cost-cutting is evident inside. Front seat passengers are welcomed with an abundance of space in terms of legroom, but rear passengers won't be as lucky. But, of course, it won't be as commodious as its 4-door sibling, the A4. As for headroom in both aspects, there's a really easy way to gain access to unlimited amounts of the stuff - simply drop the top. Eight-way power-adjustable front seats with heating are standard across all trim levels.

  • Seating capacity
  • Front Leg Room 41.3 in
  • Front Head Room 38.3 in
  • Rear Leg Room 33.1 in
  • Rear Head Room 36.3 in

A5 Convertible Trunk and Cargo Space

Convertibles aren't known for cavernous trunks that embody practicality. The rear storage area of a cabriolet is usually violated by the roof that needs a place to go, and the A5 is no different. A mere 9.3 cubes are available for luggage or anything else you may want to store in the trunk, and it's certainly not the most generous in the segment. It's beaten out by both the 2020 4 Series and the C-Class, the former offering 13 cubes.

In-cabin storage includes a decent glove compartment, generous door pockets and a storage bin underneath the center console will hold small items easily.

New Audi A5 Convertible Infotainment and Features


As expected at this price point, the A5 is decadent in all its forms. Starting with the base-level Premium model, push-button start is standard along with cruise control, three-zone automatic climate control, LED interior lighting, leather upholstery and eight-way power-adjustable front seats with four-way power lumbar support for the driver. The Premium Plus adds memory for the driver's seat and leatherette for the center console and armrests. LED interior lighting plus is reserved for the Prestige model.

Standard safety features on all models include a rearview camera, forward collision warning, lane departure warning and pedestrian monitoring. Premium Plus models add front and rear parking sensors, rear cross-traffic alert, vehicle exit warning, adaptive cruise control, active lane assist and a top-view camera system. The head-up display and traffic sign recognition are reserved for the Prestige spec.


Modern tech is bounteous in the A5 at most levels, but higher trims are upgraded significantly.

In its base form, the Premium has a 10.1-inch touchscreen that enables full smartphone integration through Apple CarPlay and Android Auto as well as Bluetooth streaming. A 10-speaker sound system is standard. The Premium Plus adds a 12.3-inch digital instrument cluster with three visual modes along with SiriusXM and wireless charging. Saving the best for last, the Premium Plus adds a 19-speaker Bang and Olufsen sound system to the mix along with a navigation system.

A5 Convertible Problems and Reliability

The 2021 A5 Convertible hasn't been recalled in the USA as yet, and the 2020 version is free of recalls, too. If reliability is a concern, Audi offers a four-year or 50,000-mile basic warranty, a 12-year corrosion warranty, and the drivetrain warranty is valid for the same time period and mileage limit as the basic warranty. Roadside assistance is standard for four years.

A5 Convertible Safety

The NHTSA has not published a review of the A5 Convertible for 2021, and neither has the IIHS. But, the latter agency has rated the hardtop 2020 Audi A5 Coupe where it managed to bag impressive safety ratings of "good" in all crash tests. The standard airbag system includes front-impact, side-impact, and overhead airbags. Standard safety features at base level are inclusive of a rearview camera, lane departure warning, forward collision warning and pedestrian monitoring while higher trims add features like front and rear parking sensors and rear cross-traffic alert.

Verdict: 🏁Is the 2021 Audi A5 Convertible a good car?

The Audi A5 Convertible is an excellent car with very little to complain about. It offers decent performance, comes in at a slightly lower price than its rivals, and is loaded with luxury. Sure, it's not super exciting to drive, but it won't disappoint in the corners or deliver an unrefined experience. It does what a four-pot-powered luxury convertible is supposed to do, which is offer a plush interior and enough power to make a decent run from zero to sixty. Perhaps there could be slightly more safety features added to the base model and its trunk is quite a bit smaller than rivals, but those are pretty much the only real gripes we can mention. The gorgeous interior is a massive plus for the A5, and so is its tendency to sip fuel considerately. The drop-top is a worthy contender by many measures and deserves your attention.

🚘What's the Price of the 2021 Audi A5 Convertible?

The cost to buy any luxury vehicle in the US is usually high, but the Audi A5 Convertible's price is decent compared to the competition. The entry-level Premium model has a starting MSRP of $50,400 while the mid-level Premium Plus bumps the price up to $55,300. You'll have to fork out $61,150 to get your name onto the Prestige model's ownership papers. All prices are exclusive of the $995 destination and handling fee.

🚗What Audi A5 Convertible Model Should I Buy?

There are three versions of the Audi A5 Convertible for sale; the Premium, Premium Plus, and Prestige. The best one to go for would likely be the mid-range Premium Plus, but we'd add a few goodies to make it an excellent all-rounder. We'd opt for the premium Tango Red metallic paint for starters and continue with the $2,100 Luxury Package that adds ventilated front sport seats and a heated steering wheel. This brings the final asking price up to $57,995, which is still more affordable than the top-tier Prestige model, but nearly as luxurious.

2021 Audi A5 Convertible vs Mercedes-Benz C-Class Convertible

Straight off of the bat, you can tell that the C-Class is not as handsome as the Audi A5 Cabrio. But this is just our opinion, and both German-bred luxury cars have well-appointed interiors. The inside of the A5 is arguably more modern, but it's rather difficult to compete with an interior set-up from Mercedes-Benz these days. The two produce similar outputs from their 2.0-liter turbos, but the C-Class is significantly less fuel-efficient in comparison. The Audi A5 cabriolet's 0-60 mph run takes six seconds, slightly faster than the Merc's 6.2-second achievement. As for performance, both of them prioritize comfort over athleticism, which isn't exactly a bad thing. The Audi A5 is the better car with all things considered, one of them being that it just has a more progressive feel inside and out.

2021 Audi A5 Convertible vs BMW 4 Series Convertible

When you put the 4 Series convertible next to the A5, it becomes relatively clear that the BMW is showing its age. This is especially true for the interior, with the BMW coming nowhere close to the A5's modern tech and cabin set-up. The A5 offers slightly more power but manages to match the BMW in terms of fuel economy figures. Both provide decent performance, but the A5 is the better car to drive. Audi's drop-top beats the 4 Series in almost every aspect for now, but it's worth noting that the 4 Series is up for a complete redesign for 2021, so we'll have to compare the A5 to the newest one when it comes out to see who truly wins the battle.
