Audi’s smallest car, the A3, benefits from a few styling revisions for the 2025 model year. Under the hood, the standard 2.0-litre four-cylinder engine returns, producing 201 horsepower and 221 lb-ft of torque. The sportier S3 also gets fresh looks along with a more potent engine (328 horsepower, 310 lb-ft), enhanced steering and suspension, plus a torque-splitting rear differential derived from the RS 3 that makes a return to the North of the Canadian border for 2025.
