The Audi A3 e-tron concept design represents the typical Audi language of sporty elegance. The single-frame grille is integrated into the front end, giving it a sculptured look. Its frame is made of carbon fiber-reinforced polymer (CFRP), and the transversely mounted, three-dimensional aluminum louvers create a visual effect that emphasizes the showcar’s width. The headlights merge with the beveled upper corners of the single-frame, forming a transition that marks the starting point of the prominently accentuated lines of the engine hood.
The A3 E-Tron Concept headlights represent a new stage of evolution in LED technology, a groundbreaking innovation from Audi. They become broader as they extend outward, and a line underneath makes them seem to float on air. Above the front spoiler is a full-length air intake, also made of CFRP, framed by a metal clasp. The spoiler features a splitter that increases the downforce on the front wheels. The intelligent interplay between surfaces and lines also defines the tail end of the A3 e-tron concept. The broad, flat tail lights are sculptured and culminate in a point on the inside, and the tailgate bears an elegant spoiler edge.

The rear apron includes a diffuser insert of CFRP and metal, which in turn surrounds the two large tailpipes for the exhaust system. Working together, the gasoline engine and electric motor accelerate the notchback to 100 km/h (62.14 mph) in 6.8 seconds, then on to 231 km/h (143.54 mph). A regulated oil pump, the intelligent Audi thermal management system, a start-stop system and an energy recovery system technologies from the brand’s modular efficiency platform all contribute to this high efficiency.

At the heart of the A3 e-tron concept are the lithium-ion batteries located behind the rear seats. A3 E-Tron Concept With a charge capacity of 12 kWh, they give the notchback a range of up to 54 km (34 miles) on electric power alone. The batteries are charged by the standard energy recovery system when the car is in motion or directly from a household power socket when it is parked. This means that in most cases, the car is entirely emission-free in city driving. The front suspension a MacPherson construction with a separate axle support has a track measuring a full 1,572 millimeters (61.89 in). The rack-and-pinion steering is extremely efficient because its electromechanical drive system requires no energy when driving straight ahead.

The audi A3 E-Tron Concept four-link rear suspension with its 1,542-millimeter (60.71-in) track is likewise fixed to a subframe. Its control arms made of high-strength steel enable the suspension to absorb longitudinal and lateral forces separately. The shock absorbers and coil springs are mounted separately from each other.
