The Kia Sonet offers three engine choices to suit different preferences and needs. First, there's a turbo-petrol engine delivering robust power (120 PS) and torque (172 Nm), available with either a 6-speed iMT or a 7-speed DCT gearbox. Second, a smaller petrol engine with a 5-speed manual gearbox provides adequate power (83 PS) and torque (115 Nm). Third, a diesel engine provides substantial power (116 PS) and torque (250 Nm), offered with either a 6-speed iMT or a 6-speed automatic gearbox, with a manual option also available. Fuel efficiency varies across these options, with the small petrol engine achieving about 18.83 kilometers per liter, the turbo-petrol iMT reaching approximately 18.7 kilometers per liter, the turbo-petrol DCT achieving around 19.2 kilometers per liter, the diesel iMT offering about 22.3 kilometers per liter, and the diesel automatic providing roughly 18.6 kilometers per liter. These figures help buyers gauge the fuel efficiency of each engine variant.
