An American concept which started in 1983 that pushes the original concept to the limits. High-torque, high-rev engines. Slot car handling. Overwhelming brakes. High performance aerodynamics and styling. Bullet-proof drivetrains. Real world ergonomics. Just plain high-tech stuff. All together. Synergistic. Each part of the system functioning individually to improve the capabilities of the vehicle as a balanced whole. Each system functioning totally to create results greater than the sum of the parts. Something good made much, much better.
