What would an unlimited car intended for a closed circuit be like?

Question

Would it have a turbine, piston, or Wankel engine? Would it have an F1 type transmission or some variety of CVT? Would it have a full body or be open wheel?

Answer 1

I'd guess turbo piston engine (it still needs to not stop for fuel too often), hybrid (more power as needed, and energy recovery, also saves the brakes), all-wheel-drive, with active aerodynamics, and probably full body. CVT only if it could handle that much power. Actually it might lack a transmission entirely, if the engine were decoupled from the powertrain and all power were from electric motors.
