Baller:
But an impresza, steve, has been designed from the ground up to be one thing and one thing only - a very quick road car. From the engine mounted as low as possible, to the 4 wheel drive system and chasis.
This is a (fairly heavily) modifid version of a ford focus.
Granted, they have great chasis to begin with, but of course its going to be cheaper, because its been modified to make into a enertaining hot hatch, not a car designed to do so with every last bolt.
Erm, isn't an Impreza actually a fairly poor hatchback, which has been developed into a rally car? Granted, flat 4 engine and 4WD are Subaru USP's, but this doesn't mean that the impreza was designed from the outset to be a rally car? Also, the Evo is a "modified" cooking Lancer, again a pretty poor starting point compared to the Focus.

It may be masked but I belive a transverse powertrain is going to force compromise in the engineering required.
Mitsubishi Evo?
phenergn:
the focus platform doesn't currently offer 4wd. They would have had to completely engineer an entire 4 wheel drive system just to offer it on a low-ish volume model. This would have added vastly to the development costs, thousands to the cost of the car and put the profitability of the project in jeopardy.
The S40/V50 are based upon the same platform, and they have 4WD options available. More likely to cause problems with assembly lines that in engineering.
Granted, the type of 4WD system isn't ideal for a performance car, but I believe it is very similar to the system used by VAG in their transverse 4Motion / Quattro cars.
