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
Hello Autocar, I am using a 4-year-old Tata Nexon AMT, and I suffered a gear oil leakage issue during the third year and an engine oil leakage issue in the fourth year. Due to the engine oil leakage, the engine had to be opened for repairs, and the car remained in the workshop for two months. Since the engine has been opened, I am wondering whether I should replace the car because of these issues. However, the car is running fine now, although I do feel there is a loss of power and mileage. I would like to know whether I should change the car now or wait a few months to understand the roadmap for ethanol blending. Also, my annual running is only around 5,000 km. Would a naturally aspirated engine be a better choice than a turbocharged engine, considering the car would remain idle for long periods? I am thinking of switching to the Maruti Suzuki Brezza TC. However, I like the Kia Sonet's interiors, but I am concerned about its turbo engine and DCT. That said, the Sonet seems like a fun-to-drive car on the highways. My usage will be around 70% city and 30% highway. Please advise.
Given your low annual running of 5,000km and the fact that the car will be idle for long periods, a naturally aspirated petrol engine paired with a torque converter automatic is the most sensible choice. The Maruti Suzuki Brezza fits this brief perfectly. It is a simple, reliable and low-maintenance package with a proven engine and gearbox combination that will serve you well over a long ownership period. The Sonet turbo petrol DCT is the more fun-to-drive option on the highway, but the DCT gearbox of this Kia car is not the ideal choice for predominantly city driving and long periods of idling. Kia Sonet mileage depends on the engine-gearbox combination. The 1.2-litre petrol MT gives up to 18.8kpl, the 1.0 turbo-petrol returns 18.7kpl (MT) and 19.2kpl (DCT), and the 1.5-litre diesel offers up to 24.1kpl with the manual and 18.6kpl with the automatic.As for your current Nexon, if the car is running fine now, there is no immediate need to change it. However, given that the engine of this Tata car has already been opened and you are experiencing a perceived loss of power and mileage, it is understandable to want to move on. On the ethanol front, there is no official roadmap beyond E20 at this stage, and modern engines are engineered to handle E20 without issue. There is no need to wait for further clarity. The Brezza is the safer and more sensible long-term choice for your usage pattern.
Hello Autocar Team, I am from Pune, and my father owns a 2021 Kia Sonet HTX 1.0 iMT. Our annual running is between 5,500 and 6,000 km, and most of our usage is in the city. Due to concerns about E20 compatibility and a significant drop in fuel efficiency, he is considering selling the Sonet and buying a Maruti Suzuki Baleno AGS (Zeta or Alpha). He also wants the convenience of an automatic transmission. His budget is Rs. 10 lakh on-road. Considering our usage pattern and fuel efficiency concerns, would buying the Baleno be a practical decision, or should he continue with the Sonet?
If your 2021 Kia Sonet 1.0 iMT is serving you well without any issues, we'd suggest you retain it. On the E20 issue, ethanol blends can reduce fuel economy slightly, but the drop is not likely to be significant enough to justify selling a good car. Keep in mind that you will lose a fair chunk of money as far as residual value goes, which won't justify the additional outlay your next new car will command.The bigger question is whether the Baleno AGS is the right upgrade. At under Rs 10 lakh on-road, you are looking at the Zeta AGS, which is a well-equipped car. This Maruti Suzuki car is comfortable, reliable and very easy to drive in the city. The AGS gearbox is an automated manual, which will be more convenient than the iMT. And the Baleno's 1.2 NA petrol will certainly be more efficient than the Sonet's 1.0 Turbo. That said, as far as quality and performance go, the Baleno will feel like a step backwards compared to your outgoing Sonet.If your father is looking for a smoother city driving experience and better fuel efficiency, the Baleno AGS is a good choice. If the Sonet is otherwise running well, there is no urgent need to sell it purely because of E20 concerns.
My running is around 2,500 km per month, currently between Faridabad and Dwarka. My route is likely to change next year, but the monthly distance should remain similar, with more highway driving than at present. Budget is max Rs. 21 lakh on-road. Looking for a safe, reliable, long-term car that is comfortable for the driver. I generally prefer sedans. For context, I drove an 8th-gen Civic AT for 2.5 lakh km and am currently driving a Ciaz AT. I've shortlisted a few options, but each seems to have a drawback: Punch EV 40 - Seats felt too hard, cabin didn't feel very premium. Sonet Diesel AT GTX - Safety concerns. Venue Diesel AT SX(O) - City fuel efficiency doesn't seem great. Curvv Diesel AT - Concerned about long-term prospects as it doesn't seem to be selling well. Verna 1.5 Turbo DCT - Worried about city fuel efficiency. City Hybrid - Stretching beyond my budget. Creta Petrol AT - Safety rating not very reassuring. Am I missing any good options? Would appreciate suggestions, especially from people with high annual running and long-term ownership experience.
Given your 2,500km monthly running, we'd actually recommend looking at a strong hybrid rather than a diesel. Our pick would be the Maruti Suzuki Victoris Hybrid. It fits within your budget, has a 5-star Bharat NCAP safety rating, offers excellent fuel efficiency in both city and highway driving, and is backed by Maruti Suzuki's extensive service network. It also provides the kind of smooth, refined driving experience that should feel like a natural progression from your Civic and Ciaz. While it isn't a sedan, it offers generous interior space and excellent long-distance comfort.Another advantage is that, being a petrol hybrid, it is a more future-proof choice for Delhi NCR. With increasing scrutiny on diesel vehicles and evolving regulations in the region, a petrol hybrid offers greater long-term peace of mind while still delivering running costs that are comparable to many diesel SUVs.The City Hybrid would have been another obvious recommendation given your preference for sedans, but as you've mentioned, it stretches your budget.Among your shortlisted cars, we'd still lean towards the Verna Turbo DCT if you want to stay with a sedan. However, with your annual running, fuel costs will be significantly higher than with a strong hybrid. The Hyundai Verna Mileage is up to 13.5kpl in real-world driving, while the DCT claims 20.6kpl as per ARAI.We would also be cautious about choosing the Seltos, Sonet or Venue diesel purely for efficiency. While all three use the same proven 1.5-litre diesel engine paired with a torque-converter automatic, it isn't the most fuel-efficient diesel automatic in real-world conditions.
I am planning to buy a new car within a budget of Rs. 12 lakh. My final choices are the Kia Sonet and the Hyundai Venue. I am a little confused about which one to choose, as I plan to make the purchase within the next 30 days. The car will be used primarily for highway driving, and good fuel efficiency is one of my key requirements. Safety and build quality are also important factors for me. Which one would you recommend?
Go for the Hyundai Venue. It sits on the newer platform and has a 5-star Bharat NCAP rating. It also has the better back seat among the two, which helps on long trips with family, and the cabin of this Hyundai car feels a touch more airy. For highway-heavy use, you could consider the 1.5 diesel, which is refined and gives good real-world mileage. The Hyundai Venue price is between Rs 8.00 lakh and Rs 15.65 lakh (ex-showroom, Delhi).The Sonet has the firmer suspension between the two; it isn't as absorbent as the Venue over rough roads, but feels a bit more planted on the highway. Kia Sonet mileage ranges from 18.6kpl to 24.1kpl, depending on the engine and transmission combination.If you’re fixed on petrol within Rs. 12 lakh, the Venue is a solid pick.
My dad wants a big SUV feel with status but under 20 lakh. He likes the Scorpio N, but I feel it will get outdated soon. We tried the Tata Sierra and Kia Caren but are still confused. We want good mileage and a full automatic. Our current car is a Kia Sonet, so driving should be on par or better.
The Mahindra Scorpio N is due for a facelift later this year, so if your father likes it and doesn't mind waiting, it could be worthwhile. However, while it has great road presence, it won't meet your other requirement of good mileage. The Scorpio N is a large, heavy, ladder-frame SUV whose focus is on strong performance and responsiveness, rather than mileage, so prepare for much lower figures than what you get in your Kia Sonet. Based on our real-world tests, Mahindra Scorpio N mileage averaged 8.65kpl for the petrol automatic and 10.15kpl for the diesel automatic, while the petrol manual returned 7.3kpl. Kia Sonet mileage depends on the engine-gearbox combination. The 1.2-litre petrol MT gives up to 18.8kpl, the 1.0 turbo-petrol returns 18.7kpl (MT) and 19.2kpl (DCT), and the 1.5-litre diesel offers up to 24.1kpl with the manual and 18.6kpl with the automatic.Moreover, owing to its top-heavy ladder-frame layout, it won't drive as well as the Sonet, at least in terms of handling and sharp dynamics. What you get instead is a commanding driving position and a tough, robust feel from the driver's seat. For a good mix of road presence and driving dynamics, check out the Sierra. The Tata Sierra price starts at Rs 11.49 lakh and goes up to Rs 21.29 lakh (ex-showroom, Delhi). Hence, you will get a decently feature-packed variant around Rs 20 lakh. Also, it is the most spacious in the class, and the turbo-petrol and diesel engines come with a smooth torque-converter automatic that works well around town and on the highway. Moreover, since it is a monocoque SUV, it has more car-like driving dynamics, easier manoeuvrability, better ride quality and better refinement. For your requirements, the Sierra is the better pick.
