One of my friends who is a mechanical engineer has an interesting history. I met him through an old college classmate of mine, who came to FL to do prototype work on a 'classic design' car in the early 1980's. It was built by a MI industrialist who wanted to make a car like the Excalibur, designer Brooks Stevens' car made in WI which used contemporary running gear and a body which bore lines lifted from the Mercedes cars of the 1930's, and other same-era cars.
My college friend did the prototype body based on input from the business owner. The car was manufactured in Pompano Beach FL. The person I met was the mechanical engineer who designed the subframe and other running gear modifications to make it work.
The Clenet was another of the 'classic era' replica cars designed around a Buick Regal unit body car and running gear. This car my friends worked-upon used another popular car of the day, the Fox-body Mustang (4th generation Mustang) which had a front subframe extension mated to the unit body of the Mustang, draped in swoopy front-fendered glory and with a huge custom front radiator grille, lights and bumper, a truly imposing look, if you were a pedestrian and saw one of these barrelling towards you.
The guys in the production shop all wanted to drive the prototype Golden Spirit which had been delivered to the business from I think it was Bobby Unser's shop in AZ. It was a Ford turbocharged V8 which was going to be a performance option for the discerning Golden Spirit customer who wanted some power to match the appearance.
The industrialist was named Zimmer, he decided to name the car the "Golden Spirit," and it came w/a spread-wing eagle perched atop the radiator shell. The phrase, "nothing exceeds like excess" certainly bears fruit in the execution of this automobile!
It had a good run, and then the market for this particular vehicle was satisfied, and the industrialist decided to close the operation. So, my engineer friend went elsewhere. The guy who was contracted to do the body went to GM in Warren MI, and he retired from there almost two years ago.
The engineer had an idea for a car of his own, and he built one prototype. Based on the work he had done for the Golden Spirit, he knew what to avoid, how to design for economy of assembly, and other considerations. What he built was truly a stunning concept. He used a 1970 Cadillac Eldorado drivetrain, which was a FWD V8 using a modified GM Turbo-Hydro 400 transmission, which used a Morse Hy-Vo drive system. It was the largest power and displacement FWD car (the Eldorado) ever produced at the time. He designed a space frame and located the Eldorado drivetrain behind the driver and passenger. I never saw it in person, but I saw a video of him driving it in the mountainous coal country roads of WV. It had an open body and resembled nothing as-much as a Can Am car for the road. At 500 cu.in., 400 HP, and 475 ft.lb torque in a car which weighed < 3000 lb, it had potential. Sadly, he was never able to find adequate financing, and as far as I know, he still has it. I still have the VCR tape of the car somewhere, I'd like to find it and post it up, but being able to locate it is low on my list of things I have to do soon. Maybe I can just ask him to send me a digital copy.
So, the RWD but mid-engined car has always been something of interest to performance enthusiasts, and cars like the 1st generation Mini-based Unipower GT and my friend's prototype were attempts to provide enthusiasts wit something they would purchase. Supposedly there is work being done on the Corvette to accomplish this, but those rumors have been flying around since the 1960's when GM made some concept cars using mid-engine design. "Is this the new Corvette?" has been asked every time the generational design was changed, but nothing like that yet.
