Well, natural Focus RS has a 215 hp engine, so I assume that owner boosted it up a little bit.....You were able to buy a Foci RS few years ago, with a 2.0 zetec and a turbo with 215 hp, but they were rare..only 4500 has been made, to my knowledge..They used few of them in America, to build a RS8 version with a Cammer 5.0 which is absolutely brutal....
I also have to admit, that is one beautifull Vette, although I like Stingray version more....
( It's hard to find V8 here in Europe, so that's why I'm defending 4 cyl's

Few more fast Foci's:
