Speculation is that it will be based on the next generation Focus. With either of two EcoBoost Fours, 1.6 or 2.0 liters. Well, if you needed to base it on any platform, you could do much worse than the Euro Focus. It looks like FoMoCo has another revived classic in their sites.
They're gunning for the Not for US VW Scirocco. Based on the already proven VW Golf GTI.
And while I'd usually gripe that we're not getting this, I'll pass on the premium price of either as long as we can get a perfomance version of the already hot hatches they're based on.
