Audi is said to be launching a Spyder version for the R8 GT at the Frankfurt Motor Show this Fall. As with the coupe version, the Spyder will be limited to 333 units and should be priced at about $20,000 higher than the coupe, which is sold for about $196,800 in the U.S. The similarities will even extend to the number of units available in the U.S. We last heard that we were getting 90 units of the GT Coupe and we expect the same number for the Spyder version.Under the hood, Audi will place the same 5.2 liter V10 engine that delivers a total of 560 HP and 398 lbs-ft of torque. The Spyder version will sprint from 0 to 60 mph in 3.8 seconds and will be capable of a top speed of 196.97 mph. Thanks to body parts made in carbon fiber the R8 GT Spyder is 187 lbs lighter and in the same time delivers performance numbers that makes it the top-of-the-line version of the high-performance sports car.
