Admittedly I don't know a whole lot about this car or series, but I was very excited by the overall shape and look of the car.
It is definitely an 80's car, and ran in the IMSA using a 1.7Liter 4-Cylinder turbo engine, and later a 2.1Liter 4-Cylinder turbo engine.
The cars were super-lightweight machines with wild aerodynamics and ground effect bodies.
Underneath all that we started with a tube chassis, and safety cage.
Here it is a little farther along.
You can see the 4 cylinder engine, and stripped interior... it hardly looks like a Mustang.
But when you add on the body, wheels, tires, and aero parts... it really does resemble a really WIDE Mustang Fox body from the 80's.
There is no mistaking that this one is built to go racing. Even with the 4 Cylinder engine in the car...
The later 2.1L Cosworth engine is said to have produced around 600 horsepower. That's about twice the power of your average commuter even now!
