While we’re eagerly awaiting for Ford to introduce a range-topping ST or even better, an RS version of the new Fiesta hatchback that is bound to hit U.S. shores in early 2010, the automaker announced the availability of new performance kit developed by Mountune, the firm’s official UK-based tuning house. Offered through selected Ford dealers in the UK, the Mountune kit for the 1.6-litre versions of the new Fiesta Zetec-S and Titanium models includes mechanical as well as cosmetic upgrades.

The engine kit that costs £1,299 (plus fitting) consists of a high-flow air induction system, a high performance exhaust including high-flow catalyst and tubular manifold, and re-calibration of Ford’s 1.6-litre Duratec Ti-VCT.

The upgrades result to an output of 140HP at 6,750rpm and 170Nm of torque at 4,250rpm, compared to 120HP and 152NM for the standard engine. As a result, 0-60 mph (96 km/h) acceleration time is reduced to a welcome 7.9 seconds from the standard engine’s 9.9 seconds.

For those that would like to accompany the engine upgrades with some visual flair, Mountune also offers a bodykit with a front lip spoiler, side skirts, a rear wing, a rear diffuser incorporating the twin tailpipes, yellow decals and mirror caps, and a set of blacked out alloy wheels with bright-yellow rings.

Developed by Mountune Performance in association with Ford Team RS, the upgrade package will only be available at selected specialist Ford dealers in Britain from March 2009. As you may have already guessed, the upgrades come with a minimum of 12 months/12,000-mile dealer warranty and do not affect the original vehicle warranty.
