I understand there are 2 approaches to twin engine design.
1. Drive the rear wheels with engine (a) and the front wheels with engine (b)
2. Use both engines’ output to drive a common gearbox
How the hell does option 1 work, is it totally reliant on electronic engine management? Seem to remember a split gearshift on a Tiger Seven replica which allowed each engine to be gearchanged separately but there must be more to it than that.
