I’m planning to buy a new car and I live in Chennai, with a budget of 15 to 19 lakhs. I have shortlisted the Kia Sonet HTX and the Skoda Slavia R 1.0. I like the Slavia, but I’m a bit concerned about its mileage. Could you provide me with the expected mileage for the Slavia 1.0 in both automatic and manual versions? Additionally, I’d like to know the mileage for both petrol and diesel versions of the Kia Sonet, including the automatic and manual options. My monthly usage is between 1000 and 1500 km. Thank you!
In Autocar India’s real-world tests, the Skoda Slavia 1.0-litre petrol manual delivers an overall mileage of 13kpl (combined city and highway), while the automatic returns 11.95kpl. The manual is more efficient because it has a direct mechanical connection between the engine and the wheels, whereas the automatic uses a torque converter, which, by nature, has some energy losses due to fluid coupling, especially in stop-start urban conditions.
The Kia Sonet 1.0-litre turbo-petrol delivers 13.5kpl in manual form and 14.05kpl with the DCT (dual-clutch automatic). The 1.5-litre diesel is more efficient, giving 17.1kpl for the manual and 16.3kpl for the automatic. The diesel Sonet is not only frugal but also surprisingly enjoyable to drive. It has a smooth and refined 6-speed torque converter automatic, which complements the diesel engine’s strong torque delivery well. The Kia Sonet price starts at Rs 7.40 lakh (ex-showroom).
If fuel efficiency is a top priority, the Sonet diesel is the better option. It’s also well-equipped and has a good-quality interior. However, the Slavia is in a different league when it comes to space, comfort, and overall driving experience. It rides better, feels more planted at high speeds, and offers a more premium feel with strong performance and good safety credentials. That said, turbo-petrol engines like the Slavia’s are sensitive to driving style—drive it hard, and the fuel economy can drop quickly.
Based on your monthly running of 1,000 to 1,500km, a diesel Sonet makes a lot of practical sense. But if you’re looking for a bigger, more comfortable car with a more engaging driving experience, the Slavia is still a compelling option—just be ready for slightly higher fuel bills.
Hope this helps you make an informed choice.
