2018 Audi A3 Sedan

in Compact sedans
2018 MODEL

$31,950 - $43,700




A large German luxury saloon can be prohibitively expensive. The Audi A3 has always tried to bring those sharp business class styling, build quality, rock-solid driving characteristics and upscale interiors in a smaller and more affordable package. The 2018 Audi A3 looks, feels, and drives like a scaled down A4 with a relatively affordable starting price of $31,950.

In spite of its price, the standard 186 hp 2.0L TFSI four-cylinder engine delivers quick acceleration befitting the premium badge. While FWD is standard, the optional renowned Quattro AWD system delivers tank-like stability even under adverse weather condition. Moreover, the A3 comes with plenty of standard features like leather upholstery and Audi MMI.

However, the rear legroom is cramped and the trunk is non-accommodating as well. Also, if you want your luxury ride to attract attention, the Mercedes CLA is decidedly more flamboyant. That said, the A3 has its own understated business class charm – like a typical Audi. On Safety front, the A3 comes with plenty of active safety features and has got 5-star crash test rating from NHTSA.

We recommend

Although the A3 Cabriolet brings the romance of open-top motoring, the sedan is more practical and less costly. We recommend the base Premium trim as the higher trims creep closer to the much larger Audi A4. We will also recommend adding the renowned Audi Quattro AWD system.



“It will come as no surprise to those familiar with Audi that the A3 feels solid and composed at speed. The ride is smooth, with the wheels rebounding quickly from impacts without much jostling in the cabin. The A3 steers easily and accurately.” – Car and Driver

If your motive for buying an A3 is to experience the famed tank-like high-speed composure and stable dynamics of expensive German saloons, you won’t be disappointed. Even with its small wheelbase, the A3 tracks straight at freeway speeds and handles long sweeping turns with aplomb. That said, Audis generally do not provide much steering feedback and the A3 is no different. Powertrain The A3 sedan gets standard turbocharged 2.0L TFSI inline-4 engine. In base FWD configuration, the engine develops 186 horsepower and 221 pounds feel of torque and is mated to a 7-speed Dual clutch automatic transmission.

Models Audi A3 Premium BMW 320i Mercedes CLA 250
MSRP $1,950 $34,900 $32,700
Engine 2.0-liter TFSI 4-Cylinder Engine 2.0-liter BMW TwinPower Turbo inline 4-cylinder engine 2.0-liter inline-4 turbo engine
Transmission 7-speed Automatic 8-speed automatic 7-speed automatic
Power 186hp 180hp 208hp
Torque 221 lb-ft 200 lb-ft 258 lb-ft

The A3 Quattro gets the same 2.0L I4 but is tuned for 220 hp and 258 lb-ft torque. To cope with higher torque load, the A3 Quattro gets a 6-speed automatic. The Audi S3 packs more grunt and the new Audi RS 3 is even more bonkers. We cover these spiced up A3s in a separate review.

“With 220 hp and 258 lb-ft of torque, the A3 provides plenty of power to accelerate with purpose” – Edmunds


Let not the price tag fool you – the A3 accelerates like a proper luxury car. Although the A3 feels momentarily slow on launch, it soon scoots forward as the turbo spool up. While even the FWD A3 can do 0-60 mph in 6.6 seconds, the A3 Quattro can reach 60 mph from rest in 5.8 seconds flat thanks to its higher power output and all-wheel drive.

“All 2018 Audi A3s use a 2.0-liter, turbocharged inline-4, either speedy 6- or 7-speed dual-clutch automatic transmission, and an available Quattro all-wheel-drive system. That is a recipe for a charming driving experience—the A3 receives a 7 out of 10 on our performance scale.” - Carconnection

Ride and Handling

The Audi A3 drives like its bigger siblings with solid high-speed stability and confidence-inspiring steering. Impressively, the steering lightens at slow speeds. This combined with the good outward visibility and tractable power delivery makes the A3 a joy to whizz around in the town.

“The A3 feels light and athletic in curves. The AWD system makes the most of available grip, and the well-tuned suspension gives it a balanced, reassuring feel.” - Edmunds

The optional sports suspension gives it more agility at a cost of harsher ride quality. If you encounter frequent bad weather, the A3 Quattro is a must have as it delivers excellent stability and the car feels like it’s turning on rails even under traction challenged situations.


The Audi A3 has a linear brake pedal response and metering the desired amount of braking is easy. The A3 stops from 60 mph in 120 feet. That’s a little faster than the Mercedes CLA which takes 121 feet to stop from 60 mph. The more expensive BMW 3-series stops faster though.

“Around town the A3 has natural-feeling brake weighting and responses. Easy to modulate. In panic braking, there's little nosedive and the car tracks straight.” - Edmunds

Fuel Economy


“The current A3 line is perfectly thrifty, with the turbocharged models returning 29 mpg combined in front-drive trim and 27 mpg combined with all-wheel drive.” - Carconnection

The Audi A3 with FWD drivetrain delivers 24 mpg in city and 35 mpg on the highway for a combined EPA rating of 29 mpg – impressive for a luxury car. The Quattro A3 with fuel-sipping AWD and the more powerful engine delivers 21 mpg in city and 31 mpg on the highway for a combined EPA rating of 27 mpg.

“Its interior is comfortable, well designed, and looks upscale despite the fact that this is the entry-level Audi.” – Car and Driver

Despite the lower price tag, the A3’s interior looks and feels every bit as high quality and solidly built as the A3’s larger brothers. And it’s loaded with upscale equipment too like the Audi MMI and Bang & Olufsen premium audio system. However, this small Audi has cozy rear seats adults should avoid. Also, the trunk volume is tight, especially in the A3 Quattro.

Seating and Comfort

The front seats of the Audi A3 offer enough room to justify the premium badge. The 41.2 inches of legroom up front is 1-inch more than that of the Mercedes CLA. Qualitatively, the standard front seats offer good support. The optional sports seats offer great lateral support for athletic driving.

“If you're single or free of children, the A3 likely will be a fine choice. Its front seats—even without the Sport Package's upgraded seats—are comfortable and supportive and there's plenty of front seat leg and head room for taller drivers.” - Carconnection

Second (Head/Shoulder/Leg) (In.) 36.4/53/35.1 37.7/55.1/35.1 35.4/53.2/27.1

While the front seats are comfortable and roomy enough to make this tiny Audi as comfortable over long distances as its bigger siblings, the rear seats are tight. This is not a limo and you have to look at the larger Audi A4 if you desire rear seat comfort. That said, the rivals like the Mercedes CLA are not any better either.

Cargo Capacity

Along with the tight rear seats, the trunk volume is tight as well. The A3 sedan offers 12.3 cubic feet of luggage capacity – almost 1 cubic feet less than that of the Mercedes CLA. The AWD system in the A3 Quattro further eats up the available luggage space.

“The A3's trunk is the smallest in the class with only a 10-cubic-foot capacity. Large golf bags or long clubs will require folding down the rear seats.” - Edmunds

Infotainment System

The Audi MMI is one of the most acclaimed infotainment systems in the automotive industry – but it’s not standard on A3. The base A3 Premium gets a standard 7-inch touchscreen and 9-speaker audio system. The convenience package ($950) brings Android Auto and Apple CarPlay capability. For the Audi MMI, you have to get A3 Premium Plus and option it with Technology Package ($3,200).

“Audi’s MMI infotainment system is one of our favorite setups in the industry. It performed well in our testing but isn’t available in the entry-level trim.” – Car and Driver

The MMI has a touchpad on rotary control with handwriting recognition – so you can directly input address in navigation. Technology package brings another Audi acclaimed feature – the superb Bang & Olufsen audio system. Technology package also replaces the standard instrument cluster with Audi Virtual Cockpit – it can show important information from touchscreen directly on the instrument cluster.



“If you like the Audi styling aesthetic, you'll love the 2018 A3’s defining look. Looking a lot like a smaller Audi A6, its standard bi-xenon headlights, big sunroof and standard 17-inch aluminum-alloy wheels make even the least expensive A3 look great.” – Kelley Blue Book

The Audi A3 sedan is styled just like its larger brothers – and many prospective owners will love it for this. The large radiator grille with horizontal slats, the horizontal stripes of LEDs on headlamps and sharp parallel lines running everywhere are all drawn from the larger A4 and A6. The side profile is dominated by a strong shoulder line that’s typical on Audi’s sedan.

The A3 premium plus even gets the upscale looking polished aluminum window frame. The wheels fill the wheel arches and this combined with other tightly proportioned design features lend this baby Audi sedan a confident stance. The LED headlights and taillights are available as $850 option in A3 Premium Plus. Dual exhaust is standard across the lineup.

Dimensions and Weight

The 2018 Audi A3 sedan is the most compact sedan currently manufactured by Audi with an overall length of 175.5 inches – that’s smaller than the comparable Mercedes CLA. However, this also means the A3 is much more manageable than other German luxury barges around town. At 6.3 inches, the A3 has more ground clearance than the Mercedes CLA and the BMW 320i.

Audi A3 Sedan vs Mercedes Benz CLA

The CLA is priced similarly to the A3 and approaches the low-cost luxury mantra similarly – by offering build quality, performance and bucket loads of standard features expected from a luxury brand in a smaller package. However, the CLA is far more flamboyant with plenty of curves – Mercedes calls it a 4-door coupe.

Audi A3 Sedan vs BMW 3-series

The BMW 3-series sits slightly above the A3 and CLA and is a quintessential sports sedan with responsive steering and rear wheel drive. It’s also roomier than the A3 and the CLA. However, the A3 is more suitable for inclement weather with its Quattro AWD and its priced lower than the 3-series.

Final Verdict

Whether you want to experience the world of premium German brands or are trading in your previous large German luxury barge for something that has a smaller impact on your personal balance sheet, the new 2018 Audi A3 sedan will impress you.

It’s got that sharp no-nonsense business class looks, the German build quality, the famed solid driving characteristics that feel like it was honed on the German Autobahn and a cabin loaded with high-end features. However, to provide you all these at a lower price, the A3 has compact dimensions. Hence, the rear seats are tight and the trunk volume is not impressive either.

So, if you need large rear seats that are comfortable for adults on longer trips, you have to spend more for the Audi A4. Same goes for the trunk volume. Still, if you mostly use the front seats and travel light and are looking for a premium German marque at a relatively low price, the 2018 Audi A3 will meet your needs perfectly.
