The Maruti Baleno has an ARAI-certified mileage of up to 30.61 km/kg (Delta CNG). Owners report a real-world figure of around 24 km/kg in mixed driving, which is typical of the 78% real-to-claimed ratio seen across this segment.
The Delta CNG variant is the most fuel-efficient, returning approximately 24 km/kg in real-world conditions against an ARAI rating of 30.61 km/kg.
The Maruti Baleno holds 37 litres of fuel, giving a usable range of roughly 644 km per full tank at real-world efficiency.
ARAI testing happens in a lab on a chassis dynamometer with the air conditioning off, no passengers and no traffic. Real Indian driving adds AC load, stop-go traffic, passenger weight and cold starts, which together cost 20-30%. A Maruti Baleno owner seeing 24 km/kg is getting an entirely normal result.
At Delhi prices, the Maruti Baleno costs approximately ₹3.13 per kilometre on cng at its real-world efficiency of 24 km/kg. Use the fuel cost calculator on this page for your own country, city and driving pattern.
