Kia Syros 1.5L Turbo Diesel-Automatic (6-speed TC) Mileage Test: Real City, Highway Fuel Efficiency

Testing Method & Flat Fuel Price Assumption

Before we provide the actual mileage of the Kia Syros 1.5L turbo diesel-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 for our real-world fuel efficiency tests. First, we fill the fuel tank to the brim, reset the trip metre, and then begin our ~100km city drive in Delhi NCR traffic. The test is conducted on the same route during weekdays to simulate realistic city driving conditions, while maintaining the same load to keep the results consistent.

For both city and highway runs, the vehicle is driven in its Normal drive mode, where available, since our goal is not to extract the highest possible fuel efficiency figures, but to evaluate how the car is likely to perform for most drivers in everyday driving situations.

Once the city run is complete, we return to the fuel station, refill the tank to the same level and note the fuel consumed to calculate the city mileage. We then reset the trip metre before starting the highway mileage test. For the highway run, we choose the stretch around Sohna along the Delhi-Mumbai expressway and we drive it for 100km at a cruising speed of around 100kmph. Then, we refill and note down the trip metre readings to calculate the highway mileage figure.

For fuel prices, we assume a flat cost of Rs. 105.00 per litre for petrol, Rs. 100.00 per litre for diesel and Rs. 95.00 for CNG. This is done to bring our calculations and cost-per-km estimations closer to a national average price of the respective fuel type. For instance, using a very low price of CNG, as applicable in Delhi, skews the final verdict in favour of CNG vehicles even though CNG is quite expensive in most states.

What Is The Actual City Mileage Of Kia Syros 1.5L Turbo Diesel-Automatic?

After driving the Syros in the city traffic for about 4 hrs 00 mins, we drove back to the fuel station. We covered 101.2km with an average speed of 25.3kmph. During refuelling, we were able to fill up 8.40 litres of diesel in the Syros at a per litre diesel price of Rs. 100.00. Thus, the total bill stood at Rs. 840.00 and in our real-world city mileage test of Syros 1.5L turbo diesel-automatic, we got a final fuel efficiency figure of 12.05kmpl.

What Is The Real Highway Mileage Of Kia Syros 1.5L Turbo Diesel-Automatic?

With the tank filled to the brim once again, we headed out on the Delhi-Mumbai expressway to test the highway mileage of the Syros 1.5L turbo diesel-automatic. We managed to complete our 107.9km drive in about 1 hrs 30 mins, meaning our average speed during the highway mileage test of the Syros was 71.93kmph. After the drive, we filled up 6.93 litres of Diesel, incurring a bill of Rs. 693.00 if you assume a fuel price of Rs. 100.00 per litre. During our highway run of the Kia Syros with the diesel-automatic, we achieved a highway mileage of 15.57kmpl.

Claimed Mileage Vs Actual Highway/City Mileage Of Kia Syros 1.5L Turbo Diesel-Automatic (6-speed TC) — What’s The Difference?

Based on our mileage test, the Syros diesel-automatic gave us a city mileage of 12.05kmpl. On the highways, you can expect this figure to jump up by 29.21% to 15.57kmpl, as we saw in our Syros mileage test.

Compared to the official claimed mileage figure of the Syros diesel-automatic, our Syros diesel-automatic city mileage turned out to be 5.60kmpl less efficient. Thus, showing a 31.73% deviation from the claimed figure. With this fuel efficiency, you can expect to incur a per kilometre fuel cost of Rs. 8.30 if you drive mostly in the city traffic with a fuel cost of Rs. 100.00.

In terms of highway mileage, we achieved a figure of 15.57kmpl with the Syros we drove. This number of 2.08kmpl is less than the claimed mileage figure. Thus, the deviation in the highway mileage of the Syros diesel-automatic is about 11.78% on the positive side. At this rate, you can expect to spend Rs. 6.42 per kilometre for predominantly highway driving during the ownership.

Kia Syros 1.5L Turbo Diesel-Automatic (6-speed TC) — Actual City vs Highway Mileage, Custom Real Mileage, Fuel Cost Comparison

If your driving happens entirely on the highways or just within the city, then you know what mileage you can expect from the Kia Syros diesel-automatic. However, for those who have a mixed usage, we have compiled combinations of effective mileage of Syros diesel-automatic based on the variations of city-highway driving ratio.

Using this customised city-highway combinations, you can better gauge what fuel costs and realistic fuel efficiency you can expect from the Syros with the diesel-automatic powertrain.

*City mileage: 12.05kmpl; Highway mileage: 15.57kmpl
*To accommodate varying fuel prices across the country, and to make the cost per kilometer information a bit more relevant for a larger number of potential car buyers, we are assuming a fixed fuel cost of Rs. 105.00 per litre for petrol and Rs. 100.00 per litre for diesel

Based on these combinations, for a 70% city and 30% highway usage, you can expect a real world mileage of 13.11kmpl and a per kilometre fuel cost of Rs. 7.63 from the Syros. With a flipped combination, where you drive the Syros 70% on the highways and 30% in the city, you can expect your real-world mileage figure to hover around 14.51kmpl with fuel costs around Rs. 6.89.

For an even split of city and highway usage, your real fuel efficiency with the Syros 1.5L turbo diesel-automatic powertrain, your effective real mileage is likely to be closer to 13.81kmpl. Thus, your per kilometre fuel costs could be around Rs. 7.24.

Real Driving Range (Full Tank Driving) Of Kia Syros Diesel-Automatic For Your Driving Requirements

The Kia Syros with the 1.5L turbo diesel-automatic comes with a 45-litre fuel tank. With this capacity and our realistic mileage estimates, you can expect to get a range of 488 - 631 km depending on whether your driving is entirely within the city or on the highways.

With a 70-30 driving split in favour of city usage, you can expect a full tank range of 531km from the Syros. However, if you flip the driving condition to 30-70 in favour of highway, then you can expect a range of 588km with a full tank of fuel. On an even split of 50% city driving and 50% highway driving, you will have to refuel about every 559km.

*Tank range estimated based on 90% fuel usage with 10% remaining in reserve

At the time of testing the Kia Syros 1.5L turbo diesel automatic, each refuelling will cost you Rs. 4,050.00 if you fill up 90%. This is assuming the fuel cost of Rs. 100.00 per litre of diesel.
