The 2024 Suzuki Swift offers notable fuel efficiency thanks to its 1.2-litre mild hybrid engine. The official combined fuel economy ratings are between 57.6 and 64.2 mpg (4.9–4.4 l/100km), with CO2 emissions ranging from 110 to 99 g/km. Real-world driving, however, usually yields slightly lower results, with several long-term tests reporting average fuel economy figures from 54 to 56 mpg (4.9–5.2 l/100km) in mixed driving conditions[1][2][3][5][6].
The five-speed manual achieves the higher efficiency rating of up to 64.2 mpg, while owners typically report 50–56 mpg depending on use case and driving style. For perspective, testers note that urban and motorway driving settle at around 54–56 mpg, while more relaxed pacing and favorable conditions can get closer to the official figures[3][5][6].
The Swift’s mild hybrid technology helps boost efficiency by providing some electrical assistance, flexibly supporting the 1.2-litre petrol engine during acceleration and start-stop traffic[2].
