Including all electrical components, the Audi A3 Sportback e-tron, which like all A3 models is based on the modular transverse matrix, has a curb weight (without driver) of just 1,540 kilograms (3,395.1 lb) – a result of Audi's strict lightweight design philosophy. Hot-shaped steels reduce weight in the occupant cell because their extremely high strength allows for thin wall thicknesses. The engine hood and front fenders are made of aluminum.

The Audi A3 Sportback e-tron is 4,312 millimeters (14.1 ft) long, 1,785 millimeters (5.9 ft) wide and 1,424 millimeters (4.7 ft) tall. Its body is sportily elongated, the front end low, and a spoiler crowns the taut dome of the roof. The design with the three side windows is taut, with every detail precise and expressive. The large wheel wells underscore the car's sporty character.

Subtle details document the special status of the plug-in hybrid model. The Singleframe grille is matt black and contains 14 fine, horizontal chrome struts. Forked chrome struts fill the air inlets. The bumpers and side sill trims have a sporty look. At the rear, the newly designed apron encompasses a platinum gray diffuser with two chrome-plated horizontal slats and two side reflectors. The exhaust system tailpipe is invisible. e-tron badges adorn the Singleframe, the luggage compartment hatch and the fenders. There are 13 paint finishes from which to choose.
