This design runs a transaxle (combined gearbox and differential) at the back of the car in an IRS arangement. There is a clutch at the back of the engine and this clutch drives the tailshaft which connects back to the transaxle.
The most common place I've seen this setup in road cars is in Alfa's.
I really don't think it's a feasible way of reducing unsprung weight in any car that wasn't designed for it from the start. You'd be far better off going for a normal IRS setup, unless for some reason you find a car with a transmission tunnel that is big enough to hold a transaxle in the rear most section.
