The answer is this Sunny...
Actually, any longitudinally oriented engine / transmission application will result in the engine sitting ahead of the near axle. Even in a Subaru, the full engine sits ahead of the front wheels, hence Subaru's persistence with the Boxer engine layout which is notably shorter over its longitudinal axis. It also has the benefit of a lower centre of gravity which goes some way to alleviating press-on understeer - especially when powering out of a corner - by virtue of less body roll resulting from the lower CofG. Same story for Porsche AWD - just put the engine in the back as you know...
Mitsu's EVO uses a FWD-based all-wheel drive system where the engine, gearbox and front differential are all transversly mounted over (and ever so slightly in front) the front axle. If you switched off all the electronic wizadry in the EVO then it too would inherently understeer just like the STI. Subarus are designed to inherently understeer. It sounds strange but for those familiar with the "power yourself out of trouble" technique this is all part of the alluring STI driving experience.
I hope to be driving the new car [you know where warot] tomorrow!
As for my trusty steed the Legacy, well, it's me and her around the Dynamic Handling track tomorrow too!
