Introduced in 2020, the fourth generation of the Audi A3 offered fewer body styles than its predecessor, the third generation. Audi produced only a sedan and a four-door hatchback. But, it does provide a selection of engines, which range from a three-cylinder to a hybrid inline-four (TFSIe), a diesel, and a five-cylinder engine with a focus on performance. The enthusiast favorites, the S3 and RS3, are also members of the family of vehicles that are in their fourth generation.
