Even lighter, even more powerful, even more captivating: The Audi R8 GT Spyder now delivers 560 hp, has trimmed 187 from an already low weight, and accelerates from zero to 62 mph in 3.8 seconds, with a top speed of 197 mph. Like the coupe, the Audi R8 GT Spyder will be a limited edition offering with only 333 examples on the roads.
