The turbocharged 2.0-liter inline four-cylinder engine in the new A3 is a familiar, proven choice for the class. It's tuned to produce 201 horsepower and 221 pound-feet of torque and is assisted by a 48-volt mild-hybrid system. Audi says that will send the A3 from 0-60 mph in 6.6 seconds (FWD) or 6.3 seconds (AWD) using regular gas. The S3 variant uses a 306 hp/295 lb-ft of torque version of the 2.0-liter inline-four, with revised turbocharger pressure and other enhancements engineered to boost performance to a claimed 4.5 seconds for the 0-60 mph run using premium fuel.
The A3 comes with a seven-speed S tronic dual-clutch automatic transmission (DCT). A DCT has two clutches but no clutch pedal. To the driver, the operation is just like a regular automatic transmission, with a throttle pedal on the right and a brake pedal on the left. Inside the transmission, though, things are a bit different. Some engineers describe the DCT as two transmissions in one case because the internal clutch shifts from one transmission shaft to the other to change gears, unlike a conventional transmission which shifts linearly up and down one shaft.
That means the DCT can shift more quickly from gear to gear. Faster shifting means less downtime between gears when the engine spins without propelling the car. Less downtime means greater efficiency and smoother shifts. Unlike the continuously variable automatic transmission (CVT) used in many highly fuel-efficient vehicles, the DCT doesn't sacrifice performance for efficiency. Steering-wheel-mounted shift paddles help the driver get the most out of the transmission and engine. The DCT in the A3 is a great asset and contributes to the car's performance character.
The A3 rides on a platform from Audi's parent company, Volkswagen Group, the same one underlying the Volkswagen GTI, Audi TT, and some other sharp-handling compacts. McPherson struts support the front end, while a four-link independent rear suspension keeps the rear from dragging.
A3 sedans come with 17x8-inch wheels (18-inch available), while S3 models use 18x8-inch wheels (19-inch available). Braking happens with four-wheel discs and a diagonal dual-circuit system with electronic stability control, anti-lock brakes, and electronic brake variator, distributing uniform force to all four brakes at once. All of this attention to detail underneath the A3 delivers a smooth, controlled ride with just the right amount of road feel. Add in electromechanical steering with speed-dependent power assistance, and you've got a crisp handling sedan that's a pleasure to drive in all situations.
We're big fans of AWD in general, especially for owners in winter climates—and not just for SUVs. A compact sedan like the A3 will see improvements in dry handling during the good weather, and with the right tires, it can handle whatever winter hands it when equipped with AWD. With 6.3 inches of ground clearance, the A3 is not a candidate for off-roading but will handle plowed roads with ease.
Our test vehicle was an A3 Premium Plus with AWD, and we took it over our regular test drives during a week of crazy weather. Rain, snow, and sleet proved no problem for the A3, which delivered confident handling, good acceleration, and sharp cornering. We sometimes felt small and vulnerable amid full-size pickups and SUVs in our midwestern town. Still, the A3's ability to squirt quickly through gaps in traffic and to swoosh through curves made up for any momentary discomfort.
EPA-rated fuel economy for the 2022 Audi A3 is 29 mpg city/38 mpg highway/32 mpg combined (FWD)/28 mpg city/36 mpg highway/31 mpg combined (AWD). The 2022 Audi S3 is a little less generous, settling for 23 mpg city/32 mpg highway/27 mpg combined.
