I remember seeing this futuristic Merc in Asphalt 8. Although this car was made before the AMG Vision GT, I refer this car as "a totally cybernetically-enhanced Mercedes Benz AMG Vision GT".

Engine Type: Unknown
Speed: 255+MPH
Power: Possibly 800+HP
Drivetrain: 4WD

I was wondering what its engine was: is it an electric engine?
