It is priced between approximately ₹7.99 lakh to ₹15.69 lakh (ex-showroom), offering a range of trims and engine-transmission options. Packed with modern touches like a digital cockpit, sunroof, ADAS Level 1, and connected-car features, the Sonet blends style and technology seamlessly. When it comes to fuel efficiency, the mileage of the Kia Sonet varies between 18–24 kmpl, depending on the engine type—making it a pragmatic choice for diverse needs from urban commutes to longer drives.
Understanding the Sonet mileage—be it for commuting, cruising highways, or evaluating running costs—helps make the Sonet a practical and cost-efficient choice. Here are the petrol mileage of Kia Sonet and Sonet Diesel Mileage for different variants:
Variant / Fuel & Transmission | ARAI-Claimed Sonet Mileage | User-Reported Mileage |
---|---|---|
Petrol Manual (1.2 L) | 18.4 km/l | Around 16–18 km/l (mixed conditions) |
Petrol iMT / DCT (1.0 L Turbo) | 18.4 – 19.2 km/l | ~14.4 km/l overall; ~12.7 km/l city; ~16.7 km/l highway |
Diesel Manual (1.5 L CRDi) | 24.1 km/l | Around 18–20 km/l on highways, ~10 km/l in city |
Diesel Automatic (1.5 L AT) | 19 km/l | Around 15–17 km/l |
Disclaimer: The mileage figures above are approximate and may vary depending on driving habits, load, road conditions, maintenance, and fuel quality. Actual Sonet mileage, including Kia Sonet petrol mileage and Kia Sonet diesel mileage, can differ from both ARAI claims and user reports.
Checking the mileage of Kia Sonet helps you track running costs, spot drops in efficiency (tyres, filters, driving style), and make smarter choices between routes, fuel types, and drive modes—vital for long-term cost-efficiency.
Fill the tank to auto-cut, then gently top-up to the first click; note the odometer or reset Trip A.
Drive normally for at least 150–250 km (mix of your usual city/highway). Keep the same drive mode (Eco/Normal/Sport) throughout.
Refill to the same auto-cut + first click at the same pump and nozzle.
Record litres dispensed and trip distance.
Sonet mileage (km/l) = Distance ÷ Litres.
Repeat over 2–3 cycles and average the results for a truer figure.
With ignition on, use the steering-wheel buttons to open the MID (instrument cluster) and reset Trip B and Average Fuel Economy.
Drive your regular loop (at least 50–100 km).
Keep speed steady (use cruise control if equipped) and avoid changing drive modes mid-test.
Read Average Fuel Economy (km/l) on the MID for instant Kia Sonet mileage; log city vs highway separately.
Re-check after a week to smooth out daily variations.
Ensure Kia Connect is active and trip logging is enabled.
Complete your commute or a fixed test loop.
Open the app → Trips/Driving Info to view distance, time and fuel economy (km/l).
Export or note multiple trips to compare patterns (peak traffic, AC usage, routes).
Use insights to optimise Sonet petrol mileage or Sonet diesel mileage.
Set tyre pressures to the driver-door sticker before testing; check wheel alignment.
Test with the same AC setting, similar load, and consistent fuel from a trusted pump.
For iMT/DCT, be gentle on throttle from standstill; for diesel MT, upshift early to use torque.
Reset readings after service or software updates to keep your baseline clean.
The Kia Sonet mileage helps in calculating the fuel required for running of the car. In this way, you can calculate the total running cost of the Kia Sonet and maintain your budget likewise. You can calculate the fuel cost of the Kia Sonet by the formula:
Fuel used (litres) = Distance (km) ÷ Mileage (km/l)
Fuel cost = Fuel used × Fuel price
Here is an example to understand how to use this formula:
Assumptions: daily commute 35 km, real-world Sonet petrol mileage = 17 km/l, petrol price ₹104/l, riding 26 days/month.
Daily fuel = 35 ÷ 17 = 2.06 l
Daily cost = 2.06 × 104 = ₹214
Monthly distance = 35 × 26 = 910 km
Monthly cost = (910 ÷ 17) × 104 = ₹5,567
Here are some tips and tricks to improve the mileage of Kia Sonet:
The Kia Sonet comes with multiple drive modes—Eco, Normal, and Sport. Keeping the car in Eco Mode during city commutes helps optimise gear shifts and throttle response, directly improving mileage.
On highways, activating cruise control helps maintain a steady speed, reducing unnecessary acceleration and braking, which can improve Sonet mileage by up to 10%.
The built-in Tyre Pressure Monitoring System (TPMS) allows you to ensure tyres are always at the recommended pressure. Under-inflated tyres increase drag, reducing mileage of Kia Sonet.
The Sonet offers idle start-stop technology in some variants. Using this feature during long signals or traffic jams saves fuel and enhances city mileage.
The automatic climate control system in the Sonet adjusts airflow efficiently. Using it in Auto Mode instead of max cooling reduces load on the engine, improving overall efficiency.
For Kia Sonet diesel mileage, ensure proper DPF (Diesel Particulate Filter) regeneration by occasionally driving at higher speeds on highways. A clogged DPF can reduce performance and mileage.
Car insurance premiums for the Kia Sonet can be influenced by its mileage, as insurers often consider how much a car is driven and its fuel efficiency when calculating risk. Higher Sonet mileage generally indicates lower running costs and can make the car more economical to insure. Moreover, with options like Pay-As-You-Drive (PAYD) car insurance, owners who use their Sonet sparingly or maintain better mileage can enjoy reduced premiums. This makes keeping track of the mileage of Kia Sonet not just important for fuel savings, but also for long-term cost-efficiency in insurance.
The Kia Sonet comes with a fuel tank capacity of approximately 45 litres, suitable for both petrol and diesel variants.
Yes, Kia Sonet mileage differs across petrol and diesel variants. Petrol models usually deliver lower mileage compared to the more fuel-efficient diesel variants.
The mileage of Kia Sonet ranges between 18–19 km/l for petrol and 22–24 km/l for diesel, depending on the engine and transmission type.
To improve Kia Sonet diesel mileage, maintain timely servicing, keep tyre pressure optimal, avoid aggressive driving, and use quality fuel.
The Sonet facelift offers improved fuel efficiency, with petrol variants giving around 18–19 km/l and diesel variants around 23–24 km/l.
Yes, in most cases, the mileage of Kia Sonet improves slightly after the first service as the engine settles and servicing optimises performance.
