The Swift was powered by a new generation of Suzuki inline-four gasoline engines .The Suzuki Swift began in 1983 as a marketing and manufacturing rebadge of the Suzuki Cultus, a supermini(or subcompact) manufactured and marketed worldwide across three generations and four body configurations.The first generation Swift was introduced in 2000 as a replacement for the Suzuki Cultus. Outside Japan, the "Suzuki Ignis" name was used. Both three- and five-door hatchback body styles were offered, although the three-door was not offered as part of the regular lineup in Japan. The second generation Swift debuted at the Paris Motor Show in September 2004. The design of the new Swift was previewed on the Concept S and Concept S2 concept cars at auto shows, in the years leading up to its launch. This generation of the Swift marked a significant departure with the previous Cultus-based models, with Suzuki redesigning the vehicle as less of a "low price alternative" subcompact and more of a "sporty" subcompact. The Swift’s design and driving characteristics focused on the European market with its chassis refined through a road-testing program across Europe.
Since its global launch in 2005, which was kicked off with a marketing campaign fronted by the footballer Cristiano Ronaldo in many European countries, the Swift has recorded above forecast sales in most markets. In Japan, sales figures have been twice the forecast and in many European markets the model has been a runaway success.
n October 2005, Suzuki launched the Sport version of the new Swift in Japan named SwiftRS, and in September 2006 the model was introduced in most European markets. Named "Swift Sport", it is powered by an enhanced M16A unit, a high-revving 1.6-litre, naturally aspirated DOHC VVT four-cylinder engine with an 11.1:1 compression ratio, high lift cams, forged pistons, and strengthened valve springs. The 1.6-liter engine produces 125 metric horsepower(92 kW; 123 hp) and 148 newton metres(109 lb·ft) torque. At 3, 765 mm(148.2 in), the car is 70 mm(2.8 in) longer than the standard Swift. The Swift Sport features sportier bumpers and spoilers, a stiffer suspension, twin exhaust pipes, red sport seats
