The Audi A3 was originally designed to offer an entry point into the German luxury brand, but that role has been taken by cars like the A1 and the new Q2 SUV.
It's built on the same MQB platform that is used under the VW Golf, and the two share many powertrain elements. The A3, though, offers a greater level of in-cabin luxury and tech. It's available as a five-door hatch, four-door sedan and two-door convertible, and is powered by a variety of petrol and diesel engines. It's also offered as an A3 e-tron plug-in hybrid.
