lol ive driven, tuned, and built several 400-500 whp front wheel drive cars. 325 at the crank is laughable, so again... based on what?
Drag racing - Yes, absolutely useless.
Roll racing - will be very competitive
Road course - hard to say, will depend on if it has a real Diff and not that E-diff crap like the Focus ST. I've literally seen their brakes catch on fire with that nonsense.
Don't get me wrong, i love the idea of an AWD badass turbo focus. I wouldn't rule out 300 hp as "too much" for a FWD though, that's just silly.
Doesn't Ford have the RevoKnuckle front suspension design? I thought I read that it did wonders for torquey FWD applications like the previous-gen RS. I didn't hear any complaints about that one and it had a ~300 HP turbo I-5.
