The future model of Indy Formula One race cars tops 235mph, and also has reduced drag and light weight which means it will only need a small four-cylinder 300 horsepower engine to propel it to such speeds, making it leaner and greener than the current conventional Indycars. Safety will also be enhanced as the risk of cars getting airborne through interlocking wheels will be reduced. Overtaking should be easier as racers will not be trapped by turbulence caused by the wings of the car in front.
