INGOLSTADT, Germany — The Audi TT Ultra Quattro Concept strips 661 pounds from the comparable production model and relies on lightweight materials as Audi continues to target weight loss.

The Ultra Quattro Concept is bound for the 2013 Worthersee Festival in May.

The concept "demonstrates how an intelligent mix of materials can bring about considerable weight savings even in existing series-production models," said Audi.

The concept is spun off the Audi TT 2.0 TFSI coupe and also gets a boost to 310 horsepower. The concept sprints from zero to 62 mph in 4.2 seconds and has a top speed over 170 mph.

Extensive use is made of carbon fiber-reinforced polymer (CFRP), fiberglass-reinforced polymer and magnesium to cut body weight. CFRP is used in the rear end, the center tunnel, B-pillars and roof. Audi engineers cut weight in all areas, including the front brakes, which feature lightweight ceramic discs and aluminum fixed calipers. The titanium exhaust system with a single tailpipe also reduces weight. Audi says the car's CFRP wheels with high-strength aluminum spokes accounted for a weight loss of 44 pounds.

The German automaker says use "of these technologies is conceivable for future small-batch series."

The showcar tips the scales at 2,449 pounds.

The TT Ultra Quattro Concept gets special Crystal White exterior paint, large spoilers, compact cameras instead of exterior mirrors and bucket seats from the Audi R8 GT.

Edmunds says: This concept is not so much about looks, but how determined Audi is to strip out every ounce of excess weight.
