Best Mileage Cars in India 2026: Petrol, CNG, Hybrid & EV

Running costs matter as much as the sticker price. Depending on how you drive, the most efficient option changes by fuel type.

Most efficient petrol: Maruti Suzuki Swift

The latest Z-Series Swift returns up to 24.8 km/l (MT) and 25.75 km/l (AMT) on the official cycle — among the best for a petrol hatchback, and it starts at ₹5.79 lakh.

Best CNG value

Factory-fitted S-CNG options on the Swift and Baleno deliver over 30 km/kg, slashing per-kilometre fuel cost for high-running city drivers.

Best hybrid: Toyota Innova Hycross

The Innova Hycross strong hybrid delivers around 23 km/l in a large 7/8-seat MPV — remarkable efficiency for its size, with 5-star Bharat NCAP safety to boot.

Lowest running cost: Tata Nexon EV

If you can charge at home, the Nexon EV's per-kilometre cost is a fraction of any petrol car, with strong real-world range and a 5-star Bharat NCAP rating.
