Every race series (F1, Indycar, WEC, NASCAR, WRC, MotoGP, etc.) is limited in some way. Rules and regulations for the sake of safety/ efficiency/sanity are bounding these (still very fast) cars.

If a team of engineers set out to create, from the ground up, the fastest possible circuit vehicle, what would that look like?

Some cars (919 Hybrid Evo) have tried, but the car is almost 7 years old and still just built off of a modified LMP1 car. The RedBull X2010 comes to mind, but is even older.

What comes to my mind is some sort of an AWD forced induction hybrid assisted drivetrain for immediate torque and top end speed. Obviously with an ultralight and strong chassis, but also aided by tons of sensors on the tires, suspension components, wings, diffusers, flaps, etc. all paired to a AI that adjusts the suspension and aero thousands of times a second for maximum grip. Could even be camera assisted, reading the track in real-time and adjusting accordingly. The driver (if we’d even have one) would wear a fighter pilot style G-suit to keep them conscious. I’m no engineer though :)
