Petrol-electric A3 E-Tron concept leads the charge for Audi in Shanghai
Audi is set to unveil a stunning technical study – the A3 e-tron concept – in Shanghai. The four-seat notchback saloon integrates the full breadth of the brand’s technological expertise – from the enhanced MMI operating system, to the high-end infotainment system, to the drivetrain. And with its two powerplants and lithium-ion batteries that store enough energy to propel the car on electric power alone for up to 54 km (34 miles), the plug-in hybrid also delivers high fuel efficiency.

Design and body
The Audi A3 e-tron concept is a four-seat notchback saloon. It measures 4.44 metres long and 1.84 metres wide, but just 1.39 metres high – proportions that underscore its dynamic character.

The styling has all the features of the typical Audi design language. The single-frame grille is integrated into the front end, giving it a sculptured look. Its frame is made of carbon fibre-reinforced polymer (CFRP), and the transversely mounted, three-dimensional aluminium louvres emphasise the showcar’s width. The headlights merge with the bevelled upper corners of the single-frame, forming a transition that marks the starting point of the prominent lines of the bonnet.

The 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. 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.

When viewed from the side, too, the A3 e-tron concept is instantly recognisable as an Audi – with its harmonious proportions, taut, muscular surfaces and a low roof dome with fluid lines flowing into a flat, coupe-like C-pillar. The shoulder area transitions elegantly into the tailgate. Characteristic of Audi design, the greenhouse accounts for one-third of the height, while the sheet metal makes up the remaining two-thirds.

Powerfully flared wings hint at the power of the engine. Two striking lines accentuate the flank: the undercut tornado line beneath the window edge and the dynamic line above the sills. The exterior mirrors, made of aluminium and CFRP, are perched on top of the window-channel strips. The door handles with their brushed-aluminium clasps are recessed flush with the door. When the driver touches them, they power-extend.

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.

Ultra-modern components, design methods and joining techniques keep the body weight low. One example of this are the custom-tailored blanks (panels of various thicknesses) in the floor area. The doors, bonnet and tailgate are made of aluminium. With its high levels of rigidity, the body provides the basis for the saloon’s precise handling, excellent vibrational comfort and low weight – the Audi A3 e-tron concept tips the scales at just 1,720 kg.
