Maruti Swift 1.2L Petrol-Auto (AMT) Mileage Test: Real City, Highway Fuel Efficiency

Testing Method

Before we provide the actual mileage of the Maruti Swift 1.2L normal petrol-automatic, let’s briefly explain our testing process so that you can decide if it matches your preferences, style and conditions for driving.

We use the tank-full-to-tank-full method, wherein we first fill up the fuel tank to the brim and reset the trip metre before commencing our 100km city drive in Delhi NCR traffic. We drive along the same route during weekdays to simulate a realistic city driving condition and with the same load to keep our test results consistent. Once we’re done with the Swift city driving, we head back to the fuel station for a refill and note the trim metre reading to calculate city mileage and reset it before once again setting off for the highway run. For the Swift petrol highway run, we choose the stretch around Sohna along the Delhi-Mumbai expressway and we drive it for 100km at a speed of around 100kmph. Then, we refill and note down the trip metre readings to calculate the highway mileage figure."
