Maruti Ertiga and Maruti XL6 are similar vehicles for those who want a roomy family car without the high fuel costs associated with vehicles of this size. The affordable Ertiga has seven seats arranged in a traditional three-row configuration. In turn, the more expensive XL6 is characterised by a bolder exterior design, more features and a second-row captain seat arrangement, resulting in a comfortable six-seat layout. Both vehicles can be equipped with petrol engines and factory-installed CNG systems.
Both MPVs use Maruti’s 1.5-litre K15C petrol engine, and their gearbox choices and efficiency technology are largely identical. Even so, their real-world mileage can differ because the XL6 is slightly larger and heavier. Passenger load and driving conditions also affect consumption. The certified figures show only a narrow difference, but city traffic and loaded highway journeys create a more useful comparison. Here is how the Ertiga and XL6 compare on specifications, mileage and fuel costs.

Since they share the same engine, it is easy to understand why their consumption figures are so similar. The petrol engine K15C is characterised by Dual Jet, Dual VVT, a stop-start function, and mild hybrid technology to reduce fuel consumption. The five-speed manual transmission offers better control of the upshifts, while the six-speed automatic transmission ensures greater comfort. CNG versions feature only manual transmission, and their power and torque figures drop when the vehicles run on gas.
The XL6 is 50 mm longer and 40 mm wider, although both have the same wheelbase. Its extra cladding, larger wheels and equipment also increase weight. This becomes noticeable in congested traffic with repeated acceleration. The lighter Ertiga can return marginally better city efficiency, although a fully occupied Ertiga may consume as much fuel as an Maruti XL6.
Maruti Ertiga vs Maruti XL6: ARAI Mileage Figures
In terms of certified efficiency, neither vehicle has an advantage over the other. The XL6 petrol with manual transmission has a slightly better rated efficiency compared to the Ertiga manual, while the Ertiga automatic surpasses the XL6 by a slight margin. Furthermore, the XL6 CNG has a higher number of kilometres travelled per kilogram of fuel consumed. However, all these differences are so small that they would not affect ownership costs in any way.
| Engine and Transmission | Fuel Type | Maruti Ertiga ARAI Mileage | Maruti XL6 ARAI Mileage |
| 1.5-litre, 5-speed manual | Petrol | 20.51 km/l | 20.97 km/l |
| 1.5-litre, 6-speed automatic | Petrol | 20.30 km/l | 20.27 km/l |
| 1.5-litre, 5-speed manual | CNG | 26.11 km/kg | 26.32 km/kg |
ARAI figures offer average rates that may be unreliable in everyday conditions. Given that the real fuel efficiency depends on a variety of factors, such as traffic conditions, bank slope, tyre pressure, air conditioning system, driving style and passenger load, it may differ significantly. Thus, we’ll have a look at the actual fuel consumption of these vehicles in different real-life scenarios.

Maruti Ertiga vs Maruti XL6: Real World Fuel-Efficiency
The Ertiga generally maintains a small city advantage, particularly with the petrol manual. The gap narrows on open roads because both vehicles share their engine and gearing. Automatic versions consume more in slow traffic, though sixth gear supports relaxed cruising. These ranges assume moderate driving and proper maintenance.
| Driving Condition | Maruti Ertiga Petrol | Maruti XL6 Petrol |
| City | Manual: 14–16 km/lAutomatic: 12–14 km/l | Manual: 12–14 km/lAutomatic: 10–12 km/l |
| Highway | Manual: 17–19 km/lAutomatic: 16–18 km/l | Manual: 16–18 km/lAutomatic: 15–17 km/l |
| Mixed driving | Manual: 15.5–17.5 km/lAutomatic: 14–16 km/l | Manual: 14–16 km/lAutomatic: 13–14.5 km/l |
| Approximate petrol range | 630–790 km | 585–720 km |
| Driving Condition | Maruti Ertiga CNG | Maruti XL6 CNG |
| City | 22–24 km/kg | 20–22 km/kg |
| Highway | 24–26 km/kg | 24–26 km/kg |
| Mixed driving | 23–25 km/kg | 22–24 km/kg |
| Typical advantage | Better city efficiency | Similar highway efficiency |
Among all petrol models, the manual Ertiga is the winner in terms of fuel efficiency. Being around town, the vehicle can get into the mid-teen figures, while driving along the highway can push consumption to the high teens compared to the low 20s of the XL6. The latter vehicle can achieve almost the same highway efficiency, though it usually loses more during slow-moving crawls. Automatics trade efficiency for comfort, especially on short journeys where idling takes longer.
CNG changes the cost equation more than the small difference between the cars. The Ertiga usually delivers 22–24 km/kg in the city, while the XL6 returns around 20–22 km/kg. Both can reach 24–26 km/kg on open roads. CNG versions sacrifice some performance and luggage space, so buyers must balance lower bills against slower overtaking and reduced boot usability.
Maruti Ertiga vs Maruti XL6: Fuel Cost Comparison
This calculation is based on a monthly period during which a trip of 1,500 km is undertaken. It is based on combined fuel economy figures of Ertiga petrol at 16.5 km/l, XL6 petrol at 15 km/l, Ertiga CNG at 24 km/kg, and XL6 CNG at 23 km/kg. It assumes Pune fuel prices at ₹112.04 per litre of petrol and ₹95.75 per kg of CNG. The actual figures will differ.
| Cost Parameter | Ertiga Petrol | XL6 Petrol | Ertiga CNG | XL6 CNG |
| Monthly running | 1,500 km | 1,500 km | 1,500 km | 1,500 km |
| Mileage used | 16.5 km/l | 15 km/l | 24 km/kg | 23 km/kg |
| Monthly fuel use | 90.91 litres | 100 litres | 62.50 kg | 65.22 kg |
| Monthly fuel cost | ₹10,185 | ₹11,204 | ₹5,984 | ₹6,245 |
| Yearly fuel cost | ₹1.22 lakh | ₹1.34 lakh | ₹71,813 | ₹74,935 |
| Five-year fuel cost | ₹6.11 lakh | ₹6.72 lakh | ₹3.59 lakh | ₹3.75 lakh |
According to this estimate, Ertiga petrol offers savings of ₹1,000 per month and ₹61,000 over five years. Savings in the CNG segment are lower, at ₹260 per month or ₹15,600 total over five years. This shows that driving conditions matter more than minor differences in certification figures.
The bigger savings come from choosing CNG. Either CNG model reduces the monthly bill by more than ₹4,900 compared with its petrol counterpart. However, buyers must consider the higher purchase price, filling-station access and reduced luggage capacity. CNG suits high-distance users, while petrol remains simpler for low annual running.

Maruti Ertiga vs Maruti XL6 Price
| Model | Variants | Approximate Ex-Showroom Price |
| Maruti Ertiga | LXi to ZXi+ | ₹8.90 lakh–₹13.04 lakh |
| Maruti XL6 | Zeta to Alpha+ | ₹11.62 lakh–₹14.57 lakh |
Ertiga is significantly cheaper and comes with more trims, including cheaper low-end versions. Conversely, XL6 is a costlier option, but it has been made attractive due to the SUV shape, captain seats, larger tyre size and more comfort and convenience features. Those looking for purely practical reasons will find Ertiga more appealing. XL6 is meant for those who are willing to pay more for more luxury in the cabin and who strictly need six comfortable chairs, contrary to Ertiga’s capacity for seven chairs. Both of them share similar engine systems; hence, the additional spend for XL6 is more for stylisation, comfort and equipment instead of making a real difference in fuel efficiency.
Summary
The Ertiga is the better mileage-focused choice in most real-world situations, particularly for city driving and high monthly use. Its lighter construction helps both petrol and CNG variants consume slightly less fuel, while its lower purchase price strengthens the overall value proposition. The XL6 remains very close on the highway and even claims marginally higher manual petrol and CNG mileage on paper, but real-world conditions usually remove that advantage. Choose the Ertiga for seven-seat practicality and minimum running costs; choose the XL6 for captain-seat comfort and a more premium experience without a major highway-efficiency penalty.
