Performance upgrades for the latest Ford Fiesta 1.6-litre petrol-engined models have been developed by Mountune Performance and are offered through selected Ford dealers.

The Mountune Performance Upgrade for 1.6-litre versions of the new-look Fiesta Zetec-S and Titanium models costs £1,299 (plus fitting), and 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 engine.

The result takes the target power output to 140PS at 6,750rpm and 170NM of torque at 4,250rpm, compared to 120PS and 152NM for the standard engine. As a result, 0-60mph acceleration time is reduced to 7.9 seconds from the standard engine's 9.9 seconds.

The new dealer-fit Fiesta performance kit follows similar Mountune Performance Upgrades for the popular Focus ST and Fiesta ST models which were made available from the beginning of 2008. All kits are fully approved by Ford and have been tested and verified on a wide range of British roads as well as numerous laps of the famous Nürburgring circuit in Germany.

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