I sure as hell can't, and I can't imagine this will possibly end well.

Before quattro everyone think that 4wd isn´t succesfull...

Someone must be 1st in everything.

You really think that Fiesta R2 isn´t successful ???

So what´s the thing then? Bore x stroke changes? Less weight moving?

Any engineers telling theoretically thoughts?

Exactly. Estonian driver Ken Torn entered 3 ERC events with this car this year. And he won them all, despite good competitors. Check out ERC3 standings:

Hmm, as far as I know the issues with Ford EcoBoost are not the case of one litre but more of the 1.5 four cylinder. The one litre has been AFAIK pretty reliable engine.
