Audi TT Ultra Quattro Concept Debuts at Wörthersee

Worthersee Audi TT Ultra 1 600x408 at Audi TT Ultra Quattro Concept Debuts at Wörthersee

At the 2013 Wörthersee event in Austria Audi came up with a very fascinating concept car based on the TT Coupe. Called the Ultra Quattro, this concept explores the possibilities of making a car as light as possible without major compromises on luxury and comfort.

The result is an Audi TT that weighs 1,111 kg, 300 kg lighter than the normal model, which still maintains most of its convenience features such as air conditioning, electric window controls and an electromechanical parking brake.

The Ultra TT is powered by a 2.0 liter four-cylinder turbo engine developing 310PS and 400Nm of torque, which translates into a 0 to 100 km/h time of 4.2 seconds and a top speed of 270 km/h.

The way Audi managed to shave that 300 kg off the weight of this TT is by using ultra-modern lightweight materials in key areas. So the body shell as well as the center tunnel, the B-pillars and the roof are all made of carbon fiber, while the brakes discs are made from carbon ceramic, the springs from Fibreglass-reinforced polymer (FRP), and the wheels from aluminum. Even the battery is swapped for a lithium-ion unit.

While these changes make a lot of sense, they cannot be yet applied to production cars because they cost a lot to produce.
