With fuel prices staying unpredictable, mileage has become a non-negotiable factor for Indian car buyers. Under a ₹10 lakh budget, the smartest choices are not the most powerful or feature-loaded cars, but those that deliver consistent real-world fuel efficiency, low service costs, and stress-free ownership over several years.
Key Highlights
- Petrol hatchbacks remain the most fuel-efficient and affordable to own
- Diesel cars make sense only for high, regular highway usage
- Manual gearboxes still return better mileage than automatics
- Ownership cost and resale value often matter more than claimed mileage
- City driving behaviour has the biggest impact on fuel efficiency
What Mileage-Focused Buyers Should Realistically Expect
Under ₹10 lakh, expectations must align with Indian driving conditions:
- Real-world mileage is usually 15–25% lower than ARAI figures
- Stop-go traffic, short trips, and aggressive throttle reduce efficiency
- Light kerb weight and smooth low-RPM driving preserve mileage
- Automatics trade fuel efficiency for convenience
Editor’s Usage Note:
Across Indian cities, owners who drive with gentle throttle inputs and timely gear shifts report the most consistent efficiency—regardless of brand.
