  • Upgraded specs to match modern passenger vehicle technology including independent rear suspension, rack and pinion steering and larger brakes.
  • A new transaxle combines the transmission and rear gears into one package with an eye on the future – the ability to incorporate electrification.
  • The bottom of the car is sealed with an underwing and rear diffuser which will help with handling in traffic and reduce “dirty air.”
  • Hood louvers will allow teams to maximize engine performance independent of aerodynamics.
  • A redesigned chassis features new front and rear bumpers for increased safety. Both the front and rear clips bolt on to the center section for easier serviceability and damage repair.
  • Upgraded car connectivity will allow for an in-car camera in every vehicle, with the ability to bring fans more real-time data in the future.
