The Toyota Rumion S CNG is the factory-fitted compressed natural gas variant of the India-market Rumion 1st Generation compact MPV, launched in 2023 under Toyota’s partnership with Suzuki and sharing its K15B bi-fuel platform with the Maruti Suzuki Ertiga CNG. It is powered by the 1462cc K15B four-cylinder DOHC engine tuned for CNG operation, producing 88 PS and 121 Nm on CNG, paired exclusively with a 5-speed manual transmission and front-wheel drive, delivering a certified 26 km/kg on CNG. The Rumion S CNG maintains the full S-grade feature set including automatic climate control, a 7-inch touchscreen with Android Auto and Apple CarPlay, halogen projector headlamps with LED DRLs, and a rear parking camera, though the factory CNG cylinder reduces boot capacity to around 180–200 litres. With Bangladesh’s extensive CNG infrastructure, this variant offers exceptionally low running costs for a seven-seat family MPV. Available in Bangladesh in very limited quantities via unofficial importers as brand-new stock.
