This Maruti Car is the Best Mileage Car Under Rs 7 Lakh in India

There's one car under ₹7 lakh that Maruti officially calls the most fuel-efficient car in India. And this car covers 34.43 km on a single kg. We'll name it in a moment. But first, let’s see what that number buys you.

"Best mileage" splits two ways in India. Petrol cars get measured in km per litre, CNG cars in km per kg. No diesel sits under ₹7 lakh anymore, so the real fight is petrol versus CNG. And this one car wins both.

Why the Maruti Celerio Is India's Most Fuel-Efficient Car Under ₹7 Lakh

It's the Maruti Celerio. The petrol version returns up to 26.68 km/l in its automatic AGS trim, the highest ARAI figure of any petrol car sold here. Pick the S-CNG version and the claim jumps to 34.43 km/kg, ahead of the WagonR and Alto CNG. At roughly 800 kg the Celerio is feather-light, and that low weight is half the mileage story. Maruti's "most fuel-efficient" tag leans on SIAM and JATO data from October 2024, so it holds up.

Price keeps the whole range in budget. The Celerio starts near ₹4.70 lakh ex-showroom, and the CNG VXi sits around ₹5.98 lakh ex-showroom, roughly ₹6.5 lakh on-road in Delhi. Every variant of the Maruti Celerio comes under ₹7 lakh.

Maruti Celerio Mileage vs What You Pay to Run It

Here's where the number earns its keep. Run the CNG Celerio at a realistic 28 km/kg, with CNG near ₹76 a kg, and you spend under ₹3 a kilometre. Drive a normal petrol hatchback doing 18km in city traffic, and you're closer to ₹5. Picture filling up twice a week and watching the meter stop well short of where petrol used to leave it.

In rupees, a 1,500 km month works out to about ₹4,100 on CNG against ₹7,900 on petrol. That gap is roughly ₹3,800. Across five years, you save somewhere near ₹2 lakh — a second car's down payment sitting in fuel bills you never paid.

But Here's the Part About Celerio Nobody Would Tell YOU

ARAI numbers are lab numbers. Nobody hits 34.43 crawling through Monday-morning traffic. Real Celerio CNG owners report around 28 km/kg, which is still brilliant for a car this cheap. On petrol it's blunter: that 26.68 figure slides into the high teens in stop-go city use, and climbs past 20 only on a relaxed highway run.

So the honest pitch isn't the headline figure. It's that even after the real-world cut, nothing under ₹7 lakh costs less to run. The 1.0-litre three-cylinder engine is light and simple, and Maruti's service network keeps the bills small. You're not buying thrift over safety either, with dual airbags and ABS standard and six airbags offered higher up.

Which Celerio Is the Best Mileage Buy for You

If you clock high kilometres, the Celerio CNG VXi is the one. The maths only improves the more you drive. If your runs are short or highway-heavy and refilling CNG sounds like a chore, the petrol AGS gives you that 26.68 figure with an easy automatic. One thing to raise with the dealer: the CNG cylinder eats into the 314-litre boot, so check your weekend luggage still fits before you sign.

End Note

A fun note to close on. The Celerio was India's first car with an AMT, back in 2014. Ten years on, it's quietly doing the one job budget buyers care about most, turning every rupee of fuel into more kilometres than anything else at this price. Chase the real number, not the lab one, and the Maruti Celerio still tops the best mileage car under ₹7 lakh category.
