The Audi R8 GT Spyder high-performance sports car develops 560 hp and has trimmed a full 187 lbs (85 kilograms) from an already low weight. The R8 GT Spyder accelerates from zero to 60 mph in 3.6 seconds and reaches a top speed of 197 mph (317 km/h).One year ago, Audi unveiled the R8 GT in coupe form as the new flagship model of the R8 model line. It wasn't long before all 333 units in the limited series were sold out. Now the open-top version of the high-performance sports car is being launched, with production again capped at 333 units. Each car sports a tag with its individual number on the gear lever knob.
The Audi ultra lightweight technology is the key to the R8 GT Spyder's weight of just 3,616 lbs (1,640 kilograms). That's 187 lbs (85 kilograms) less than its technical basis, the R8 Spyder 5.2 FSI quattro. The Audi Space Frame (ASF) body, consisting of cast nodes, extruded sections and aluminum panels, accounts for just 214 kilograms (471.79 lb) of the total weight. The body is assembled predominantly by hand in the R8 workshop at the Neckarsulm plant. Final assembly of the car takes place in the same way.
The engine frame is made of ultra-light magnesium; the long cover over the soft-top compartment and the large side panels at the rear are made of carbon fiber-reinforced polymer (CFRP). CFRP is also used for the modified front spoiler, the fixed rear spoiler and the new rear bumper. Together, these components provide a weight saving of 12 lbs.
