Looking instantly recognizable, the redesigned sedan follows in the footsteps of the A3 and adopts a prominent single frame grille that is flanked by slender headlights. The car also has door-mounted mirrors, a dual exhaust system and a new trunk whichappears to have an integrated rear spoiler. Other notable highlights include evolutionary taillights and longer rear doors which should improve access to the cabin.

Bigger changes occur underneath the skin as the model is expected to ride on the MLB Evo platform which uses a combination of aluminum and high-strength steel. This change could enable the model to weigh about 100 kg (220 lbs) less than its predecessor.

Engine options are expected to include the usual suspects but there should be a new plug-in hybrid variant that uses a 2.0-liter TFSI petrol engine and a 95 bhp (71 kW) electric motor. This could enable the sedan to travel up to 31 miles (50 km) on electricity alone.
