I happened to watch NACAR's Daytona 500, with the new 'aero' cars.
Near the end of the race, one of the cars was pushed sideways, became a primitive 'wing' went airborne, and landed on its roof, remaining 'turtle' until the responders could right the car.
The footage provided a really good look at the Mustang race car.
The cooling system's engine bay extractors were located right after the front wheelhouses, with the duct wall radiusing seamlessly into the rocker panels.
The exhaust is completely enclosed above a full belly pan and diffuser, every bit as clean as a Tesla, Lucid Air, Lamborghini, etc..
The 'outgoing' car technology is 'caveman' compared to the new racers.
