by Ford on a select range of cars such as the Ford Escort Cosworth and Mk.1 Ford Focus RS edition models. The colour was not available on the regular Pumas in the UK market. Gearbox and optional limited-slip differential The standard IB5 gearbox was strengthened on the Racing Puma in comparison to the standard models. It contains modified shafts, which have been shot peened to withstand the extra load placed upon them. This allowed a revised Power-train Control Module software to be used, allowing more power and torque to be used in lower gears. Additionally, Ford Racing offered an optional limited-slip differential to enhance handling even further, only 75 customer cars actually came equipped with that option from factory, but since then, subsequent owners have been known to retrofit it. Racing-inspired interior Sparco were commissioned to provide high-grip bucket seats for improved driver control in cornering situations. The blue Alcantara trim used on the seats and steering wheel provided improved grip over other material types. The door cards, rear seats, and rear interior were also trimmed with the same material, and the front seats were embroidered with the Ford Racing emblem. FRP engine The original design remit was to achieve 180 bhp using a 1.7-litre Zetec SE equipped with a turbocharger. However, due to spiralling project costs, this was not achieved and eventually the Racing Puma engineers were forced to keep their changes within a naturally aspirated engine. The majority of the engine remained unchanged from the 1.7 Zetec SE used in the standard Puma. Only the camshafts, air intake (with the unique edition number engraved on it), a specially tuned complete exhaust system by Janspeed, and a revised engine management software helped to increase power by 30 hp, reducing the 0- time to 7.8 seconds, achieving a 126 mph (203 km/h) top speed. Racing Rallying Ford produced a Ford Puma kit car, which was designed specifically for rallying. The Puma's technical details included a Zetec SE all-alloy engine with four cylinders and 16 valves at 1596 cm3, power over at 9000 rpm, front wheel drive via a Hewland six-speed sequential gearbox, limited slip differential, dynamic front suspension using MacPherson struts with adjustable spring platforms, Ford Racing rear trailing arm beam with adjustable dynamic suspension, Alcon front brakes with diameter ventilated discs using four-piston calipers, Alcon diameter solid disc rear brakes with two piston calipers, a welded steel safety roll
