Double engine cars?

So I had this idea about cars with two engines. First of all I have no idea is this old, so don't flame me if it is.
I'm talking about concepts or modified cars which have 2 engines, preferably one in the front and one in the back. The idea is:
What if we make one engine drive rear wheels and the other will drive front wheels? (there would be 2 separate and independant units) Is this a good idea or bad? Could it boost preformance? I thought that we could take this a little further and install 2 pedals, each for every engine (similiar to separate brake pedals for rear and front wheels in race cars). Maybe it could give the driver more control. Tell me what you think.

Seperate control is a bad idea
The ones I've seen use linked accelerator cables, share clutch and gear linkages.

Otherwise you coudl change one to 3rd the other still in second and succeed in pulling your vehcile apart Or how abotu accidently put one in reverse and the other in first. Good for generating wheel smoke for sure

A few years ago Mosler was promoting a twin-engined Cadillac Eldorado, apparently well engineered and supposedly offered in turn-key form. C&D tested one, it seemed a positive review

I had to go read it. Interesting, takign two different engines makes it a MUCH bigger challenge. Tryign to match the power/torque woul dhave been hard

I hope they got the electronics right, it would be nightmariesh if during hefty cornering one of the engines decides to shift gear, creating violent over/understeering reactions, depending on which engine it is.

and if my predefined objective was to build a car with two engines and have the front engine drive the back and so, those would be necessary problems

John Cooper had a twin engined Mini, basically fitted a second engine/gearbox/subframe in the back. I believe a driveshaft broke and caused quite an accident :S Someone has created a replica, from what i rememeber seeing in MiniWorld they shared clutch and gear linkages, but had a split accelerator pedal; each half of it controlled each engine. You could kinda lean your foot on one side and rev one engine, and so one axle, more than the other, the idea being (with some practise) you could balance the speed differential between front and rear. I didnt actually buy that issue so thats all i can remember of it
