6th September 2013
In celebration of the 30th anniversary of the Sport quattro – the musclebound short-wheelbase coupe originally conceived for the rally stages – Audi will unveil its conceptual, plug-in hybrid successor at the 2013 Frankfurt Motor Show.
Engineers at Audi have made every effort to keep vehicle weight to a minimum to maximise the range of the hybrid vehicle. The occupant cell combines ultra-high-strength steel panels and cast aluminium structural elements. The doors and wings are made of aluminium, and the roof, the bonnet and the rear hatch are made of carbon fiber.
Other, more easy to miss details include the headlights which do not have a fascia, exposing the LED heat sinks, while the tail lights reduce glass and housing to a minimum. In addition, the support structure of the interior is a carbon shell that also serves as a storage compartment in the side doors making elements of the lightweight construction visible.
Finally, lightweight carbon fiber reinforced plastic (CFRP) is used for the the flared sills and the power door handles which extend automatically to meet an approaching hand. The result is a kerb weight including the battery pack of just 1,850 kilograms.
The vehicle achieves 0-62mph in 3.7 seconds, top speed 189mph, 113mpg and 59g/km.
The Frankfurt Motor Show takes place during 12th-22nd September 2013.
