Which A3 does Edmunds recommend?

We recommend the Quattro variant not solely for its all-wheel drive, but also for the nice bump in power it delivers over the front-wheel-drive version. Keep it simple, staying with the base Premium trim, to prevent the price from creeping up to A4 levels. The Convenience package has a lot of bang for the buck, and the Sport package's upgraded seats, selectable drive modes and optional sport suspension make it a worthwhile choice, too.

Edmunds' Expert Review

Overall rating

7.3 / 10

The latest-generation A3 debuted in 2015 and marked a departure from the previous edition, eschewing the hatchback body style for sedan and convertible body styles. It then received a modest face-lift in 2017.

The A3's debut came just one year after that of the Mercedes CLA-Class, marking the dawn of a new entry-level era among German automakers. BMW has yet to introduce a sedan in the vein of the others, instead doing battle with its rear-wheel-drive 2 Series coupe.

The A3 Cabriolet models lose the roof but gain reinforcements elsewhere to shore up the structure. In the bargain they gained about 250 pounds compared to their sedan counterparts. The power-folding top is fully lined, but its narrow rear window and large, unbroken swaths of fabric obscure visibility.

Under the skin, the A3 is closely related to the Volkswagen Golf. That's no bad thing, as both are quite accomplished compact cars. Be aware that it's possible to option up an A3 to an eye-watering degree. At some point, buyers might consider an A4 over a heavily optioned A3.

2018 Audi A3 configurations

The 2018 Audi A3 is offered in four-door sedan and two-door convertible (Cabriolet) body styles. Both are available with front-wheel drive or all-wheel drive. The trim levels are named Premium, Premium Plus and Prestige, which are listed in order of increasing content.

Front-wheel-drive A3 models have a turbocharged 2.0-liter four-cylinder engine (186 horsepower, 221 pound-feet of torque) and a seven-speed, dual-clutch automatic transmission. These models have a fuel economy edge over their all-wheel-drive siblings to the tune of 2 mpg (EPA combined). All-wheel-drive variants (Quattro) have a similar engine, but a few changes elevate its gumption to a more robust 220 hp and 258 lb-ft. Perhaps paradoxically, Quattro variants have one fewer gear in their dual-clutch automatic transmissions than do front-wheel-drive models. Despite this and their inevitably heavier weights (160 pounds for sedans; 200 pounds for convertibles), Quattro models handily out-accelerate their front-wheel-drive counterparts. No manual gearbox is available on any flavor of A3.

The base Premium is well-equipped, sporting features such as leather upholstery, a backup camera, dual-zone climate control, a panoramic sunroof, forward collision warning and automatic emergency braking, a 10-speaker sound system, heated front seats and an eight-way power driver seat with power lumbar adjustment. Cabriolet models are similar but have a power-folding soft top, a nine-speaker sound system and six-way power front seats with lumbar support.

For a reasonable sum, Premium Plus adds a mix of cosmetics and worthwhile convenience features such as 18-inch wheels, an eight-way power passenger seat with lumbar support, blind-spot monitoring with rear cross-traffic alert, keyless ignition and entry, parking sensors, and Apple CarPlay and Android Auto smartphone integration. These models also gain exterior appearance items such as revised bumpers, side sill extensions and illuminated aluminum front doorsills.

Prestige goes all out with power-folding mirrors, LED headlights, an expanded Virtual Cockpit instrument cluster, navigation, a Bang & Olufsen premium audio system and a host of driver assistance features (including lane departure warning, adaptive cruise, automatic high beams).

Some of the features found on the Premium Plus and Prestige can be added to the lower trims as options. An optional Sport package is available on all three trims; it adds a sport steering wheel with wheel-mounted shift paddles, sport front seats with extendable thigh support and selectable driving modes. A sport-tuned suspension is optional with the Sport package selected.

Trim tested

Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our full test of the Audi A3 Prestige Quattro Convertible (turbo 2.0L inline-4 | 6-speed dual-clutch automatic | AWD).

NOTE: Since this test was conducted in 2015, the current A3 has received some revisions, including a host of new driver assistance and cabin features, along with optional Apple CarPlay and Android Auto integration. Our findings remain applicable to this year's A3, however.


Audi's familiar turbocharged 2.0-liter engine makes 220 horsepower and 258 pound-feet of torque in Quattro guise, which is enough for confident passing and merging. While the A3 Cabriolet isn't a sports car, its precise steering and good body control give it a sporty feel.


The powertrain feels hesitant off the line, but once the turbo kicks in, you're going places. Compared with others in the class, the 0-60 mph sprint of 6.2 seconds is just OK. The sedan is a half-second quicker (and 300 pounds lighter).


The A3 Cabriolet showed excellent braking composure, stopping straight with intuitive pedal feel, no extraneous motions and zero brake fade after repeated hard stops. A panic stop from 60 mph took 120 feet with all-season tires — a satisfactory but not stellar result.


Our test car's steering effort was adjustable via Audi's Drive Select system, but even the heaviest Dynamic setting still felt light. Path control is very good, though, and this precision inspires confidence in real-world driving.


Our tester, equipped with the optional sport suspension, felt nimble and composed. No surprise there; the suspension tune and MQB platform mean it's kind of like a Volkswagen Golf GTI convertible. But there's little playfulness at the handling limit. The A3 is capable but not particularly exciting.


The light steering makes parking maneuvers a breeze, as does the A3's compact size. Rev-matched downshifts from the dual-clutch transmission are awesomely quick and precise. The transmission can feel sleepy at low speeds but is mostly on point.


Manually adjustable front seats with modest bolstering offer generous space but could hold occupants tighter. The rear seat is tight, though the BMW 2 Series is similarly cramped. On the bright side, the ride is supple and the top creates a well-insulated cockpit when it's in place.

Seat comfort

Our A3 Cabriolet's Sport package included manual front seats that offered wide adjustability. There's not much lateral support by sport-seat standards, and rear seat comfort is hurt by a lack of space.

Ride comfort

Even with the optional firmer suspension, the ride remained reasonably supple over most surfaces. Mild wobbling of the windshield was noted on rough patches, as were occasional pops and creaks from the top of the windshield with the soft top up.

Noise & vibration

Top up, the A3 Cabriolet is well-insulated from the elements. Talk radio on the highway is easy to hear. Lower the roof and you'll notice wind noise and buffeting at speed. The wind-blocker reduces both but makes the rear seats unusable.


Audi is renowned for its superlative interiors, and the A3 is no exception. The austere dashboard takes Audi's minimalism to a new level, but the effect is distinctly upscale. The cramped back seat and trunk are on par with what you'll find in the 2 Series.

Ease of use

The controls are well-placed for quick access while driving. The knob-based MMI infotainment system is responsive and pretty easy to get the hang of. The central display screen provides crisp graphics and sensible menus.

Getting in/getting out

The long, heavy doors can make you think twice in tight spots. The A3's sedan roots mean the front seats aren't too low; you don't fall down into them. Rear seat access isn't the issue; it's the lack of space once you get back there.


There's no shortage of space up front. The wheel telescopes out as far as you need. The rear seats have climate vents, which is a nice touch, but also hard armrests, limited legroom and scant top-up headroom. The Cabriolet looks like a four-seater but is more of a 2+2.


The relatively thin windshield pillars mean excellent visibility out the front. Rear visibility is predictably limited with the top up. The high beltline makes you feel ensconced within the car, but drivers with short torsos might complain.


The interior materials are beyond reproach, even in this entry-level Audi. Supple and thoughtfully textured materials are everywhere. Knobs and levers move with well-damped fluidity. Top-shelf engineering and construction is evident.

Convertible top

The A3's power soft top has a lot of real estate to cover from windshield to rear deck, and it shows in the leisurely 19.3 seconds required to power it down (20.5 seconds on the way up). The top stows neatly under its tonneau lid.


The A3 Cabriolet loses a pair of doors along with its roof, but thankfully it doesn't give up much of its already limited trunk space. Still, you'll have to pack smart and keep in-cabin personal effects to a minimum.

Small-item storage

Though pleasing to the eye, the A3's clean interior design lacks storage solutions, with modestly sized door pockets and a small console bin and glovebox.

Cargo space

The A3 Cabriolet's trunk loses a negligible amount of space on paper at 9.9 cubic feet and it's fine for a grocery run or a weekend getaway. But it's slightly smaller than the BMW 2 Series' cargo area, and it's not wide enough to stow a full set of golf clubs.

Best car I have ever owned and driven. It exceeds my expectations. It’s the quietest convertible I’ve ever been in and the digital cockpit will blow you away.
I'm talking to you
Speech dialogue or voice recognition was disabled by Audi in my car. This was a major annoyance since neither Audi tech headquarters nor my dealer had any idea what to do to install the needed software. I had to show them online comments from other owners with this problem and how they got it corrected. Your dealer CAN download needed software to enable voice recognition. Other then that, this is a great car. High quality interior, superior acceleration and ride comfort. A few minor design improvements I would like are: more light in the trunk and since the doors are very wide, an inside door handle closer to where the door opens so it is easier to control. Also another "catch point" to hold the door open when getting out. As it is now, you must open the door quite a bit before it catches open. Combined with it being hard to control the door due to the placement of the handle, this can take some doing.

Should I lease or buy a 2018 Audi A3?

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.
