Kia Sonet Mileage
Kia Sonet mileage has one clear standout. ARAI certifies the diesel manual at 24.1kpl, well ahead of everything else in the range. The diesel automatic is rated at 18.6kpl, the 1.2-litre petrol manual at 18.8kpl and the 1.0-litre turbo with the dual-clutch at 18.7kpl. In our own mixed driving we saw above 10kpl from the turbo-petrol and around 15kpl from the diesel.
Which model fits my driving:
The diesel manual at 24.1kpl is the reason to choose diesel here, and it is 5.3kpl clear of the petrol manual.
Choosing the diesel automatic gives away most of that advantage, dropping to 18.6kpl and landing level with the petrols.
Our tested figures of around 15kpl for the diesel and above 10kpl for the turbo are the numbers to budget against.
The three petrol and diesel automatic figures sit within 0.2kpl of each other, so mileage will not separate them.
If your running is high, the diesel manual is the only version here that changes your fuel bill meaningfully.

Questions you may find useful
I currently drive a Hyundai i10 CNG, with daily running of around 6 km in Gurgaon city traffic and a monthly highway drive of around 200 km. I am now planning to upgrade my car, with an on-road budget of Rs. 12 lakh for a petrol sub-4-metre SUV, up to Rs. 14 lakh for a petrol midsize SUV, and Rs. 15 lakh for an EV. I live in a rented apartment on the second floor, so I am apprehensive about getting an EV. I prefer an EV, but installing a charger could be complicated due to the sanctioned load. My running could increase to nearly 800 km per month in the future. My key priorities are: - Good suspension and ride comfort, as I have a back problem - Decent fuel efficiency in heavy city traffic - Low to medium maintenance costs - Auto hold and ventilated seats would be good to have I sometimes consider buying a manual, but I mostly prefer an automatic. I am currently considering the Maruti Brezza, Baleno AMT, Fronx AMT/AT, Sonet iMT, Exter AMT, and even the upcoming Inster, VF3, and Bayon. I am open to other suggestions as well. Note: I had a bad driving experience with the Punch AMT, as it caused back fatigue.
Given your priorities of ride comfort, fuel efficiency and low maintenance, the Maruti Brezza automatic is the most sensible upgrade. It offers a comfortable ride, a proven naturally aspirated petrol engine and Maruti's strong service network, which keeps long-term ownership costs in check. The torque converter automatic is smooth in city traffic, and the Brezza's higher seating position will help with your back issues. The Sonet iMT is not the right choice here. While it is a good car, the iMT is not a true automatic and will not offer the same ease of use in Gurgaon traffic. The Baleno AMT and Exter AMT are also not ideal given your back issues and the fact that AMT gearboxes are not as smooth as torque converter automatics in stop-start conditions.On the EV front, your apprehension about charging is valid. Without a straightforward home charging solution, an EV will add unnecessary complexity to your ownership experience. The upcoming Bayon is interesting and if you can wait a few weeks you would have a better picture before making a decision. For now, the Brezza automatic strikes the best balance between comfort, efficiency and hassle-free ownership.
@autocar.india I am a sonet owner and regret buying it. It is possibly the worst car an automaker can make. It's suspension is worse than a rickshaw! The car rocks ,wobbles and jerks on the slightest of potholes or even smooth speed breakers. The service pple Were equally useless in terms of not doing a thing about the suspension. Coming to mileage It's real mileage is only 6-7max in traffic. By reducing overall cost kia has made a 3rd grade car which is not worth even 5 lacs Sincere advice not to even consider it. Am selling it off in only 2 yrs . k
I am planning to buy a car in the Rs 12-13 lakh price range and will travel around 1,000-1,200km on the highway every month. Should I go for the Sonet diesel, or would a petrol car be a better choice? If petrol is the better option, please suggest cars with good mileage, as fuel efficiency is my main concern.
With 1,000-1,200 km of highway driving per month, the Kia Sonet diesel is a sensible choice. At that kind of running, the fuel cost savings of diesel over petrol become meaningful, especially on highways where diesel engines are at their most efficient. The Sonet diesel is a strong highway performer, with good torque for overtaking and a relaxed cruising nature. It is also a well-rounded package with a comfortable ride and a decent feature set.If you are open to petrol, the Maruti Suzuki Brezza is the best alternative. It is one of the most fuel-efficient petrol SUVs in the segment, and Maruti's ownership experience and service reach are hard to beat. However, the fuel cost difference compared to diesel will still be noticeable in your running costs.
I am planning to buy a sub-compact SUV. My budget is Rs. 13-14 lakh, and my priorities are a smooth automatic transmission and good mileage. I am considering the Brezza ZXi AT, Sonet HXT DCT, and Venue HX6 DCT. I am very confused because the Brezza’s torque-converter automatic offers good fuel efficiency but lacks some features, while the Sonet and Venue offer all the features I need. However, I am concerned that the DCT may be less fuel-efficient and could involve higher maintenance costs. My daily commute is around 30 km, mostly in heavy bumper-to-bumper traffic. Please suggest which one would be the best choice for my requirements.
Go for the Maruti Suzuki Brezza ZXI AT. Your priorities are a smooth automatic, good fuel efficiency and a daily 30km commute in heavy bumper-to-bumper traffic. The Brezza’s 6-speed torque converter automatic is the best fit for this usage. It is smooth, reliable and well suited to stop-start conditions, and the naturally aspirated petrol engine is efficient and easy to live with. Maruti’s service reach and low maintenance costs add to the ownership peace of mind.The Sonet and Venue DCTs are good cars, but the DCT gearbox is not ideal for heavy traffic. It can feel jerky at low speeds.Alternatively, if you can arrange for home charging, the Tata Punch EV is an excellent option.
I have been using a Grand i10 manual for the last eight years and am now planning to get a new vehicle for my wife, who will be a new driver. Her monthly commute will be around 700km, with 500km on the highway and the remaining distance in stop-and-go traffic. The vehicle will also be used for long trips, mostly on the plains. My priorities are comfort and space for a family of five, a peppy engine, reliability for 10-12 years, and pocket-friendly maintenance costs; last is mileage. I don't like Tata or Mahindra cars. My budget is Rs 15-17 lakh. I am considering the Honda Elevate and Sonet diesel. Please feel free to suggest any other cars.
Go for the Honda Elevate petrol CVT. It is the best fit for your requirements. The Elevate’s CVT automatic is smooth and convenient, making driving in city traffic far less stressful. It is also a reliable, fuss-free car that will comfortably last 10-12 years with Honda’s strong service network and low maintenance costs. The cabin is spacious enough for a family of five, and the ride is comfortable on long highway trips. The petrol engine is refined and peppy enough for your usage, and you avoid the long-term concerns around diesel ownership as emission norms tighten.The Kia Sonet diesel is a good car, but it is smaller than the Elevate, and the diesel automatic doesn't make sense given your usage. The Honda car mentioned above is the more sensible, long-term choice.
