Maruti and Suzuki engineers improved the Swift's fuel efficiency via changes in engine hardware leading to improved thermal efficiency, reduced frictional losses, and calibration changes.

Maruti Suzuki’s recent refresh of the Swift resulted in a 10% improvement in the car’s fuel efficiency, owing largely to powertrain refinements. With a certified fuel efficiency of 25.2 km/L, up by 10%, the Swift Diesel is powered by the 1248cc DDiS 190 compression-ignition engine returning a claimed 190 N·m (140 lb·ft) at 2000 rpm and 75 ps (55 kW) at 4000 rpm. The Swift Petrol, with a 9.67% FE improvement at a certified 20.4 km/L, features a 1197cc K series VVT gasoline engine that delivers 84 ps (62 kW) at 6000 rpm and 115 N·m (85 lb·ft) at 4000 rpm. Among the innovations by Maruti and Suzuki engineers to improve fuel efficiency include changes in engine hardware leading to improved thermal efficiency, reduced frictional losses, and changes in engine calibration. The compact combustion chamber and higher compression ratio on the gasoline engine helps to improve engine efficiency, while the advanced thermal management system along with low friction engine oil and a modified fuel injection system help the diesel engine in faster warm up and lower frictional losses, according to the company.
