The 2018 Audi A3 Sedan is a subcompact sedan offered in 3 trims, starting off at a base MSRP of $31,950. For that price, it mainly competes with the Acura ILX Sedan, the Mercedes-Benz CLA 250 Sedan, and the Cadillac ATS Sedan. Between 3 trims, the A3 Sedan offers 2 powertrains. The FWD models are powered by a 2.0L turbocharged inline-4 capable of making 186 horsepower and 221 lb-ft of torque. This engine comes mated to a 7-speed dual-clutch transmission. However, the quattro AWD models get a similar but more powerful, 220 horsepower-making 2.0L turbocharged inline-4 engine. It comes paired with a 6-speed dual-clutch automatic transmission. The FWD A3 Sedan reaches 60 mph from zero in 6.6 seconds, which gets pumped up to 5.5 seconds in the AWD models. Depending on the powertrain, the A3 Sedan can manage a combined fuel economy between 27 and 29 mpg. While we’re on the topic of choices, the 9 striking colors the A3 Sedan comes in really pull you towards itself.
