It's a 2.0 liter engine. It's 95% rally car technology and 5% fiestaI think most people on here have probably seen it given that we're Ford fans. But thank you for pointing out once again that the Fiesta Rally/Rallycross cars are amazing! 650hp/660ft lbs. from a 1.6L...no problem.
The only thing that could make this (and all of his gymkhana) video(s) better would be if Ken Block wasn't such a failboat rally driver.
