Are you able to answer my question Avant ? About the pros and cons of transverse mounted engines over north south ?
The answer depends on whether front, rear or all wheel drive.
Transverse engines are not ideal for rear wheel drive, transmission is much simpler if north/south engined (eg BMW, Mercedes, LGVs). A clutch change may be easier with this layout (if sensibly designed).
Front wheel drive and transverse engines permit a shorter bonnet (so more compact car) and no need to turn transmission 90 degrees from flywheel to drive shafts.
Handling is thought to be generally safer for most drivers if front wheels driven, the almost universal adoption of this arrangement suggests it is cheaper/simpler to manufacture.
The first front wheel drive cars (Cord, Citroen) and Indianapolis race cars until 1964 all had north/south engines.
Four wheel drives mostly seem to favour north/south engines, probably as they use transfer boxes and it facilitates using them.
