Maruti Ertiga Mileage: ARAI vs Real-World Mileage
The Maruti Ertiga is one of India’s most popular MPVs, and fuel efficiency is one of the reasons many families consider it. It is available with a petrol manual, a petrol automatic and a factory-fitted CNG option. Each version has a different claimed mileage, while the figures you get in everyday driving can vary depending on traffic, passenger load, driving style and road conditions.
So, what mileage can you actually expect from the Ertiga? This guide covers the official ARAI figures, reported real-world mileage, running costs and estimated range to give you a clearer idea of what each version can offer.
Maruti Ertiga ARAI Mileage
Maruti Suzuki currently lists three mileage figures for the Ertiga. The petrol manual is rated at 20.51 km/l, while the petrol automatic is rated at 20.30 km/l. The factory-fitted CNG version has a claimed efficiency of 26.11 km/kg. These are figures certified by the relevant testing agency under the applicable testing rules.
| Variant | Fuel and Transmission | ARAI Mileage |
| LXi MT, VXi MT, ZXi MT, ZXi+ MT | Petrol, 5-speed manual | 20.51 km/l |
| VXi AT, ZXi AT, ZXi+ AT | Petrol, 6-speed automatic | 20.30 km/l |
| VXi MT, ZXi MT | CNG, 5-speed manual | 26.11 km/kg |
The CNG version has the highest claimed efficiency in the Ertiga range. It is available only with the 5-speed manual gearbox, while the 6-speed automatic is offered with the petrol variants. Maruti Suzuki lists the Ertiga as a seven-seater in both petrol and CNG versions.
Maruti Ertiga Real-World Mileage
ARAI mileage is useful when comparing different cars because the figures are produced under standardised test conditions. However, your actual mileage can be different. City traffic, frequent stops, air conditioning, passenger load and driving habits all have an effect.
The figures below are based on reported owner mileage and should be treated as indicative rather than guaranteed results.
| Variant | ARAI Mileage | Reported Real-World Mileage |
| Petrol MT | 20.51 km/l | 18.77 km/l |
| Petrol AT | 20.30 km/l | 17.97 km/l |
| CNG MT | 26.11 km/kg | 23.18 km/kg |
In everyday use, the difference between claimed and reported mileage is not unusual. The Ertiga is often used as a family car with several passengers and luggage, which can increase the load on the engine. Air conditioning can also have a noticeable effect, particularly in slow-moving city traffic.
It is worth treating owner-reported mileage as a range rather than a fixed number. One Ertiga owner may see a higher figure on an open highway, while another may get considerably less in heavy urban traffic.
What Affects Ertiga Mileage in Daily Driving?
Several everyday factors can change how much fuel your Ertiga uses.
- Passenger load: A fully loaded Ertiga carrying several passengers and luggage will generally use more fuel than one carrying only one or two people.
- Air conditioning: Running the air conditioner continuously, especially in slow traffic, adds to the engine’s workload. Cooling a full cabin can also increase fuel consumption.
- Traffic conditions: Frequent braking and acceleration in congested traffic generally result in lower mileage than steady-speed driving.
- Driving style: Smooth acceleration and avoiding unnecessarily high engine speeds can help improve fuel efficiency.
- Tyre pressure: Underinflated tyres increase rolling resistance. Checking the tyre pressure regularly can help maintain the expected efficiency.
- Short trips: Frequent short journeys can return lower mileage because the engine spends more time warming up and less time operating at its normal temperature.
- Road conditions: Hilly roads, rough surfaces and frequent gradients can also reduce fuel efficiency compared with flat roads.
For an Ertiga used mainly for family trips, the difference between a lightly loaded car and one carrying six or seven passengers can be noticeable.
Maruti Ertiga Fuel Cost Comparison
To understand the difference in running costs, consider an Ertiga covering 1,500 km every month. The table below uses the reported real-world mileage figures above and assumed Delhi fuel prices of ₹102.12 per litre for petrol and ₹86.98 per kg for CNG.
| Expense | Petrol MT | Petrol AT | CNG MT |
| Monthly fuel cost | ₹8,161 | ₹8,524 | ₹5,629 |
| Annual fuel cost | ₹97,931 | ₹1,02,290 | ₹67,542 |
| 5-year fuel cost | ₹4,89,655 | ₹5,11,450 | ₹3,37,710 |
These figures are estimates based on constant mileage, fuel prices and monthly usage. Actual costs will change if fuel prices or your monthly driving distance changes.
At these assumptions, the Ertiga CNG could save roughly ₹1.52 lakh in fuel costs over five years compared with the petrol manual. Against the petrol automatic, the difference is around ₹1.74 lakh.
This comparison only looks at fuel costs. The CNG version has a different purchase price and running costs can also vary between variants, so fuel savings alone should not be used to calculate the exact ownership break-even point.
Maruti Ertiga Mileage vs Competitors
The Ertiga’s closest mechanical relative in this comparison is the Toyota Rumion, which also uses a 1.5-litre K-series petrol engine and is offered with petrol and CNG powertrains. Toyota lists 20.51 km/l for the manual petrol version, 20.11 km/l for the automatic and 26.11 km/kg for the CNG version.
The Maruti Suzuki XL6 uses the same 1.5-litre K-series engine family and has slightly different claimed mileage figures. Maruti lists 20.97 km/l for the manual and 20.27 km/l for the automatic.
| Model | Fuel and Transmission | ARAI Mileage |
| Maruti Ertiga | Petrol MT | 20.51 km/l |
| Toyota Rumion | Petrol MT | 20.51 km/l |
| Maruti Ertiga | Petrol AT | 20.30 km/l |
| Toyota Rumion | Petrol AT | 20.11 km/l |
| Maruti Ertiga | CNG MT | 26.11 km/kg |
| Toyota Rumion | CNG MT | 26.11 km/kg |
| Maruti XL6 | Petrol MT | 20.97 km/l |
| Maruti XL6 | Petrol AT | 20.27 km/l |
The Ertiga stands out for offering a factory-fitted CNG powertrain while retaining its seven-seat layout. Buyers who want an automatic, however, need to choose the petrol version.
Maruti Ertiga Driving Range
The Ertiga has a 45-litre petrol tank. Maruti lists a 60-litre water-equivalent CNG cylinder for the CNG version.
Using the reported petrol mileage figures above, the petrol manual could theoretically cover around 845 km on a full 45-litre tank, while the petrol automatic could cover around 809 km.
These are calculated estimates rather than guaranteed ranges. Traffic, driving style, air conditioning and fuel level can all affect the actual distance.
For the CNG version, it is better not to give a fixed range by simply multiplying 26.11 km/kg by the tank capacity. The amount of CNG filled can vary depending on filling pressure and conditions. The car can also use petrol as its other fuel, making the overall touring range dependent on both fuel supplies.
Which Ertiga Should You Choose for Mileage?
The right version depends mainly on your monthly running and how you use the car.
- Petrol MT: This makes sense if you want a balance of efficiency, purchase cost and everyday usability and are comfortable driving a manual.
- Petrol AT: This is worth considering if you spend a lot of time in city traffic and prefer the convenience of an automatic gearbox. The claimed mileage is only slightly lower than the manual.
- Ertiga CNG: This can make sense if you cover a high number of kilometres every month, have convenient access to CNG stations and want to reduce your fuel expenses. The trade-offs include the manual-only transmission and the space taken up by the CNG system.
If most of your driving is within a city with easy access to CNG stations, the lower fuel cost can make the CNG version particularly relevant. For buyers who regularly travel long distances through areas with limited CNG availability, petrol can offer greater refuelling flexibility.
Tips to Improve Maruti Ertiga Mileage
You do not need to make major changes to your driving to improve fuel efficiency. A few simple habits can help.
Accelerate smoothly instead of pressing the throttle hard from a standstill. With the manual, shift up at appropriate engine speeds and avoid holding lower gears longer than necessary. With the automatic, use smooth throttle inputs and avoid repeated hard acceleration.
Keep the tyres at the recommended pressure and avoid carrying unnecessary weight. If your Ertiga is mainly used for short city trips, combining several errands into one longer journey can also help reduce inefficient cold starts.
Regular servicing is important as well. Follow Maruti Suzuki’s recommended service schedule and have the engine, tyres and other relevant systems checked when required.
Final Word
The Maruti Ertiga offers a useful spread of mileage options depending on the powertrain you choose. The petrol manual has a claimed 20.51 km/l, the petrol automatic is rated at 20.30 km/l, and the CNG version is rated at 26.11 km/kg.
In real-world driving, the numbers can be lower and will depend heavily on traffic, load, air conditioning and driving habits. The petrol versions offer the flexibility of easier refuelling, while the CNG version can reduce fuel costs for buyers with high monthly running.
Ultimately, the most useful mileage figure is the one you can realistically achieve on the roads you drive every day. ARAI figures are a good starting point, but your own driving conditions will determine the final fuel bill.
