Mountune Focus ST and Fiesta ST: Driven

The Mountune touch is most certainly a good one. It was brave of Ford to allow third-party branding on its performance models, but the take up on previous generation models was strong, and now we have a new upgrade for the Focus ST and the Fiesta ST arriving on the same day. I drove both yesterday.

0-100mph in 14 seconds? Quick Focus!

You've read the news story, but just to remind you, the Focus ST kit gives 275hp and 295lb ft. It's a very classy piece of calibration work, to the point that initially you're a little underwhelmed. Where the previous five-cylinder model with the Mountune kit immediately felt unhinged, this one builds boost more gradually, but the numbers are still impressive. On a stinking hot day and a pretty poor launch I managed 0-60 in 6.4 seconds and 0-100mph in 14.0 seconds. Ford claims it'll go under six seconds to 60mph, which I find a little hard to believe, even if you had several goes at trimming the 0-30mph time. The standing quarter was 14.7 seconds.

The engine's character is pretty much identical to the standard motor only with more of everything, all of the time. My only gripe is that when you try to shift very fast right on the limiter the ECU sometimes delays full power by a fraction of a second after the gearchange. Shift 500rpm lower and it doesn't happen. The noise is especially good for a four-pot.

Still cheaper than a Clio RS, now with 215hp

The Fiesta upgrade is less involved but for me even more impressive. The numbers are 215hp and 236lb ft on overboost. Yes, that's 236lb ft in a Fiesta. The results are very amusing on the road. In fourth gear the little Fiesta will nail stuff with much more imposing badging. I managed 6.5 seconds to 60mph, 100mph in 15.4 seconds and the standing quarter in 14.94 seconds. The car is much easier to launch than the Focus, the 2.7-second 0-30mph time shows what should be possible in the bigger car, but even then I don't see the Focus going under six seconds to 60mph.

So for an extra £599 you can have a fully warrantied Fiesta that will do 0-100mph in 15.4 seconds. That is absolutely bonkers and could make life even more difficult for the Clio RS. There will be a video soon.

One word of caution, we asked an insurance company whether these fully-approved upgrades affected premiums - for a 21-year-old male they reckoned an additional 10-15 per cent.

The Focus ST upgrade includes an airbox and a fancy air filter, so costs quite a bit more at £1,225.

They're both cracking upgrades and it's hard to imagine ordering either car without them given they don't invalidate the manufacturer's warranty.

But for me the Fiesta was the funnier by far. And that's what a tuning should be about.

    Well that Fiesta upgrade seems a no-brainer for that price. Very nice indeed.

    Brilliant! £599 to find come September when our Fiesta ST arrives....! biggrin

    ..a quick Focus indeed, i havent checked but its peformance stats look almost identical to a 1997 fiat coupe turbo...thought things might have moved on abit since then..

    Still reckon (putting aside all driving dynamics, fun factor etc) looking at the various vids of the 3 cars (clio,208,fiesta) drag racing I reckon the clio would still pip the fiesta as it has such a lead over the 1/4 when the Fiesta is standard. 208 would have no hope though.

    I have to say Im not a massive fan of Ford but i'm looking forward to my work mate's Fiesta being delivered so I can have a go. Looks so much fun.

    Credit Ford as you say, wonder if anyone will be brave enough to take these warranted tuning packages to their logical extension?
