Outline

The Kia Sonet might pack plenty of style and features, but with fuel prices this high, everyone deserves a few extra kilometres on the existing mileage. With just a few simple steps, you can easily give a boost to the Sonet mileage on highways and in city traffic. In this blog, we’ll provide insights into the real-world mileage and ARAI figures, understand what affects the fuel economy, and how to increase the Sonet mileage. Keep scrolling.

 

Sonet ARAI Mileage

 

Before we dive into real-world scenarios, let’s take a look at the ARAI-certified Sonet mileage figures. These figures are tested under controlled-chamber benchmarks:

 

  • Diesel Automatic: 19.0 kmpl
  • Diesel Manual (1.5 Litre): 24.1 kmpl
  • Petrol DCT, Manual, and iMT: 18.4 kmpl

 

Sonet City Mileage

 

The actual world Sonet mileage is quite different when compared to the ARAI one. This will provide you with a much clearer picture of the vehicle's everyday performance:

 

  • Diesel Auto: The mileage is close to 13.8 kmpl.
  • Diesel Manual: The mileage is roughly 15.4 kmpl in the city.
  • Petrol Auto: It's around 11 kmpl to 12 kmpl.
  • Petrol Turbo iMT: It stands at 12.35 kmpl.

 

Factors Affecting Sonet City Mileage

 

Certain factors can have a massive effect on the Sonet mileage while driving in the city. Here are some of the primary ones:

 

1. Traffic Conditions

 

The stop-and-start traffic means periodic braking and accelerations, which use plenty of fuel and also have a massive impact on the mileage.

 

2. Air-Conditioning Use

 

When you keep the AC on a high level, it increases the load on the engine. In return, it lowers the efficiency and also uses more fuel.

 

3. Tyre Pressure

 

If your vehicle has under-inflated tyres, it will make the engine work much harder, which will lower the mileage.

 

4. Vehicle Weight

 

When the vehicle is carrying many passengers or has considerable luggage, it will lower the acceleration and use a lot more fuel.

 

5. Driving Style

 

Driving the vehicle aggressively or braking suddenly burns more fuel.

 

6. Engine Health

 

Having old oil and dirty filters can prevent the vehicle from functioning smoothly, and it will also consume more fuel that way.

 

Improving Sonet City Mileage

 

Here are some quick and super-easy ways to increase the Sonet mileage:

 

1. Smooth Acceleration

 

When driving the vehicle, you should press on the accelerator gently and also avoid instant throttling.

 

2. Keep the Car Well-Maintained

 

You should periodically change the filters and oil of the vehicle, as it will keep the engine in excellent condition and also improve its performance.

 

3. Use the AC Smartly

 

One great way to enhance the Sonet mileage is by keeping the AC in moderate fan speeds or just in Eco Mode instead of using it in full blast.

 

4. Gentle Driving Style

 

You should brake and accelerate the vehicle softly for a much better fuel economy during stop-and-go traffic.

 

5. Maintain the Correct Tyre Pressure

 

Make sure to inspect the pressure of your vehicle's tyres every month. That way, they will keep rolling resistance to a minimum. 

 

Sonet Highway Mileage

 

When you drive the Kia Sonet on an open road, the vehicle's efficiency is much better than in city conditions: 

 

  • Diesel Auto: The mileage is roughly 18.8 kmpl.
  • Diel Manual: Mileage is approximately 20.8 kmpl.
  • Petrol iMT: It's around 15.8 kmpl to 16.5 kmpl.
  • Petrol Auto: The mileage is 17.7 kmpl.

 

The real-world tank-to-tank tests from some owners even reveal a mileage of over 20 kmpl in the diesel manual.

 

Factors That Impact Sonet Highway Mileage

 

When driving on highways, there are some aspects that can have a massive impact on Kia Sonet mileage. Here are some of the main ones:

 

1. Cargo Weight

 

Heavy loads can lower the acceleration efficiency, even when you're driving on highways.

 

2. Cruising Speed

 

The Sonet mileage will start to drop when you hit speeds above 90 km/h because of the wind drag.

 

3. Quality of the Engine Oil

 

Using low-quality or old oil can increase friction, which will, in return, affect the fuel efficiency on long drives.

 

4. Tyre Condition

 

Worn-out and misaligned tyres can increase the rolling resistance and significantly lower the Sonet mileage.

 

5. Aerodynamic Drag

 

Roof carriers and even open windows will add air resistance, and also lower the overall mileage.

 

Increasing Sonet Highway Mileage

 

Here are some ways that can help you increase Highway mileage: 

 

1. Maintain Steady Speed

 

Use cruise control for a smooth pace and fewer throttle fluctuations.

 

2. Close Windows and Reduce Drag

 

Keep windows up and remove carriers to improve aerodynamics.

 

3. Check Alignment

 

Get tyres aligned every 10,000 km to reduce resistance.

 

4. Use Correct Oil

 

Stick to Kia’s recommended oil grade for optimal lubrication.

 

5. Lighten the Load

 

Carry only essential cargo to avoid slowdowns on inclines.

 

6. Plan Flat Routes

 

Choose flatter roads when you plan the route to maintain steady speeds without steep climbs.

 

Summary

 

The Kia Sonet offers strong ARAI figures up to 24.1 kmpl on diesel manuals, but real-world conditions bring those numbers slightly down. City mileage ranges from around 12 kmpl in petrol variants to 15 kmpl to 15.5 kmpl in diesel manuals, while highway drives deliver better returns, over 20 kmpl in diesel manuals and 17 kmpl to 18 kmpl in petrol automatics. These mileage figures also apply to used Kia Sonet models. When you keep the tyres in good shape, drive smoothly, reduce weight, and stay on top of maintenance, you can significantly boost the Sonet mileage and save significantly on fuel costs in the long run
