(continued from above)
The Audi A3 e-tron concept is a four-seat notchback sedan. It measures 174.8
inches (4.44 meters) long and 72.4 inches (1.84 meters) wide, but just 54.7
inches (1.39 meters) high - proportions that underscore its dynamic character.
The 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 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.
When viewed from the side, too, the A3 e-tron concept is recognizable at first
sight 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 fenders hint
at the power of the engine. Two prominently elaborated lines accentuate the
flank: the undercut tornado line beneath the window edge and the dynamic line
above the sills. The exterior mirrors, made of aluminum and CFRP, are perched
atop the window-channel strips. The door handles with their brushed-aluminum
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, engine hood and tailgate are
made of aluminum. With its high levels of rigidity, the body provides the basis
for the sedan's precise handling, excellent vibrational comfort and low weight -
the Audi A3 e-tron concept tips the scales at just 3,792 lbs (1,720 kilograms).
