2017 Audi A3 vs. 2017 Mercedes-Benz CLA-Class: Compare Cars

Mercedes-Benz and Audi have inserted new entry-level compact cars into their lineup the past several years, with the CLA and the A3, respectively. These two have very different packaging, style, and driving personalities, and they appeal to an entirely different kind of buyer.

Which are you? To get there, a good starting point might be to point out all the similarities, and then home in on the differences.

TCC’s Bottom Line
If you can live with its tiny rear seat, the 2017 Audi S3 is an absolute hoot to drive. The 2017 Mercedes-Benz CLA-Class is a sharp-looking sedan that washes its hands of back-seat space, and stuns us in CLA45 AMG trim.
