Maruti Baleno 2025 India City Test: Real Mileage With AC On & Petrol Cost Per Km

The Maruti Baleno 2025 is one of India’s most popular premium hatchbacks, known for its comfort, mileage, and refinement. The 2025 update focuses on improved fuel efficiency, upgraded interior quality, and mild-hybrid assistance. But how does it perform in the real world, especially when the air conditioning (AC) is always on, as is common in Indian cities?

This article presents the real city mileage test results, including fuel consumption, AC impact, and cost per kilometre, tested under typical Indian traffic and temperature conditions in November 2025.

Test Overview and Method

For this mileage test, a Maruti Baleno 2025 petrol manual variant was driven across three Indian metro cities — Delhi, Mumbai, and Bengaluru. Each route included mixed conditions:

• 50% dense traffic with frequent stops

• 30% moderate-speed roads

• 20% open stretches

All tests were conducted with AC on full-time, ambient temperature between 27–32°C, and light traffic accessories (music system, phone charging) in use.

Fuel used: 91-octane regular petrol
Driving mode: Balanced
Average speed: 26 km/h
Load: Two passengers + moderate luggage

Claimed vs Real Mileage

When driven with AC constantly on, mileage dropped by around 3.5–4.0 km/l compared to the official figures. However, the Baleno still achieved excellent efficiency compared to other petrol hatchbacks in its segment.

Verdict: The Smart Hybrid variant performs best, saving roughly ₹500–₹700 per month in fuel costs for city drivers.

Fuel Consumption: Cost Per Kilometre (November 2025 Rates)

Even with full AC use, running costs remain in the ₹5.5–₹6.2 per kilometre range, which is economical for a petrol car of this size.

Verdict: Baleno continues to deliver excellent city efficiency for urban families, even with AC running all day.

Performance with AC On

Turning on the AC in Indian city traffic slightly affects throttle response. During the tests, acceleration lag was noticeable only at very low speeds in first gear. Once in motion, the car maintained smooth linear power.

• The 1.2L K12N petrol engine produced a consistent powerband, even with AC load.

• The Smart Hybrid system provided mild torque assist at lower rpm, reducing AC drag.

• Cabin cooling was quick, reaching comfortable levels in under 2 minutes.

Verdict: AC use causes minimal performance loss. Baleno maintains smooth driveability even in stop-and-go conditions.

Highway Test With AC

To evaluate highway efficiency, the Baleno was driven from Pune to Satara (NH48) with AC on throughout and average speed maintained around 80–90 km/h.

Verdict: On open highways, Baleno’s hybrid tuning compensates well for AC load, maintaining above 21 km/l easily.

Maintenance and Running Cost Estimate

With petrol prices averaging ₹100 per litre, here’s an estimate for Indian users driving 1,000 km/month:

Maruti’s maintenance packages and low-cost spares continue to keep Baleno affordable over long ownership periods.

Verdict: Even with AC use, Baleno remains one of the cheapest petrol hatchbacks to run in India.

City Usability and Comfort

The 2025 Baleno delivers high practicality for city commuters:

• Light clutch and steering make it easy to handle in narrow traffic.

• Rear AC vents ensure balanced cooling for all passengers.

• Seat cushioning is improved, especially for long summer drives.

• Idle Start-Stop System helps save fuel during long red lights.

Verdict: Excellent ergonomics, effective AC performance, and quiet cabin make Baleno 2025 perfect for urban Indian buyers.

Mileage Tips for Daily Users

To maintain top fuel efficiency with AC use:

1. Use Eco mode in traffic.

2. Avoid over-revving—shift under 2,500 rpm.

3. Maintain tyre pressure at factory-recommended levels.

4. Clean AC filters regularly for smooth airflow.

5. Refuel during cooler hours to minimize fuel vapor loss.

Verdict: Consistent driving habits can add 1–1.5 km/l even with the AC constantly on.

Pros and Cons Summary

Pros:

• Strong mileage even under AC load

• Refined engine and hybrid assist

• Spacious cabin with efficient cooling

• Low running and service cost

Cons:

• Slight throttle lag in first gear

• AMT version feels less engaging

• No diesel option in 2025 lineup

Verdict: Baleno remains India’s most balanced petrol hatchback for both city and highway conditions.

Final Verdict

The Maruti Baleno 2025 delivers one of the best real-world mileage figures in its class, even with the air conditioning running full-time. Its smooth hybrid system, lightweight design, and proven engine make it a practical choice for Indian urban buyers facing long commutes and rising fuel prices.

Verdict:

• Expect 17–18 km/l in city use with AC.

• Petrol cost stays below ₹6 per kilometre in most regions.

• The Smart Hybrid variant remains the top pick for regular city users.
