I thought that twin engined cars had one gearbox and one clutch so that the power from both engines goes through a shared torque converter, however I've also heard of twin engined cars with two gearboxes with the front engine driving the front wheels and the rear engine driving the rear wheels.
In that case, isnt there a chance of one pair of wheels turning faster than the other pair?
I don't suppose there's anyone who knows what a drive-by-wire system is?
As well as having venturi tunnels for the rear engine, another issue would be the exhaust for the secondry engine e.g. a rear engine in an Escort. A full system would need to be customised to snake round, yet avoid the exhaust from the original engine, although I have heard of flexible stainless steel exhausts.
Well that's all I know about twin engined cars ? .
I'd appreciate it if anyone can clear things up for me )
