Not saying the RS wouldnt be nice but when you start doing 350 hp, AWD, and low 4 sec to 60 it comes into question when youd be able to use it in 99% of driving.

I suppose that tailored power transfer is a real boon to the drift mode. Im not familiar with the STI awd system, isnt it just a center and rear diff meaning it can only send power to all wheels or at least the slipping ones which would leave torque vectoring to the brakes?

Sense as in slow car fast? Lol

I wonder if moving away from difs has any other benefits in weight and maintanence and if losing the difs means you lose a bit in other places. Side note does that mean the RS can run FWD at times?

Because the ST, IMO, has a more usable amount of power. I would rather hoon the ST AWD to 8/10 of its ability than try to scratch 5/10 of the RS abilities.

100% would buy RS chasis with ST motor. Ford make it now please

The most important would probably be the Acura concept because it shows details for the entire lineup going forward. The next would be the Avista (mmm beautiful) because it tells of just one model.
