Mercedes-Benz has just unveiled its latest supercar, the AMG Vision Gran Turismo, but there's a catch. The supercar you see here was designed exclusively for "Gran Turismo 6," meaning that no road-going versions of this model will be produced. However, Mercedes-Benz did create this 1:1 scale model for the opening of its new Research & Development Center in Sunnyvale, California. The AMG Vision Gran Turismo features an AMG V8 with 577 horsepower and 590 lb-ft of torque, and an aluminum space frame with carbon fiber components to keep the weight down. Like the recent Mercedes-Benz SLS and the 300SL from the '50s, the Vision Gran Turismo comes complete will gullwing doors. Players will be able to drive the new supercar when "Gran Turismo 6″ launches in December.
