Along with the launch of the Dzire CNG-AMT automatic powertrain in September 2026, Maruti Suzuki also revised the engine specs of the Dzire 2026. With the new engine map, the biggest change in the specs is visible in the mileage figures, which have gone up quite a bit. The Dzire was already quite efficient and with this update, it further widens the gap with its rivals.

With the Dzire petrol, the new engine tuning gives it a boost of 1.35PS in power and 0.7Nm in torque. For the peak power output, this is a 1.65% improvement. In torque, the Dzire witnesses a modest 0.63% jump. More noticeable is the peak torque RPM, which moved higher from 4300 to 4500.
However, the biggest gains for Dzire petrol manual and automatic come in the mileage department. The Dzire petrol-manual’s mileage figure has gone up from 24.79kmpl to 25.15kmpl, which is a 1.45% improvement. The Dzire petrol-automatic (AMT) got a 0.42kmpl improvement in mileage as its ARAI figure went from 25.71kmpl to 26.13kmpl. This is a 1.63% change in the positive direction.
The following table shows the old vs new engine specs and mileage comparison of the Dzire petrol after September 2026 update:
With the Dzire CNG powertrains, we see even bigger changes. The most prominent change for September 2026 being the addition of a CNG-automatic powertrain. This new Dzire CNG-automatic powertrain has an ARAI mileage figure of 36.47kmpkg.
The Dzire CNG-manual’s mileage figure also saw an improvement of 1.92kmpkg as it went from 33.73kmpkg to an impressive 35.63kmpkg. This is a substantial change of 5.63%.
The power and torque figures of the Dzire CNG-manual remain intact with absolutely no change from the 2026 September update.
