It caters to large families, fleet operators, and anybody seeking a 7-seater car that is economical to run. Many potential buyers want to know how the Ertiga handles real-world mileage situations, especially with increasing fuel expenses.
In this blog, we will discuss the Maruti Ertiga’s real-world mileage along with its performance in mixed conditions, highway cruising, and city traffic. We will also examine the engine and transmission options, cover important factors affecting Ertiga mileage, compare variants, and offer tips on improving fuel efficiency.
Maruti Suzuki Ertiga Engine and Transmission Options
The Ertiga comes with several engine options tailored for different user demands. The table below highlights the Maruti Suzuki Ertiga Engine and Transmission options.
| Engine Type | K15C Smart Hybrid |
| Displacement | 1462 cc |
| Max Power | 103 PS |
| Max Torque | 139 Nm |
| No. of Cylinders | 4 |
| Valves Per Cylinder | 4 |
| Transmission Type | Automatic |

Depending on transmission type and fuel system, these engine choices deliver different real-world actual fuel efficiency. Though practical, petrol automatic models usually deliver slightly less mileage than manual ones, especially in city driving. High-mileage users love the CNG version for its great running cost advantages.
Claimed vs Real World Mileage
The Maruti Suzuki Ertiga’s mileage always astounds, regardless of whether it is the manual or automatic petrol version or the SCNG variant.
Maruti Suzuki Ertiga now has the NextGen 1.5 L K15C engine available in either SCNG technology or smart hybrid technology. Both automatic transmission (AT) and manual transmission (MT) options of the car are available in petrol. Regarding fuel economy, the Ertiga offers 20.51 kmpl (MT) and 20.30 kmpl (AT) in its petrol versions. The SCNG variation, by contrast, provides 26.11 km/kg. Let’s examine the claimed vs real-world Ertiga mileage.
ARAI-Certified Mileage
| Variant | ARAI Mileage |
| Petrol Manual | 20.51 km/l |
| Petrol Automatic (6AT) | 20.30 km/l |
| CNG Manual (Petrol mode) | 20.51 km/l |
| CNG Manual (CNG mode) | 26.11 km/kg |
These figures are tested under ideal test conditions; however, they do not accurately represent real-world events, such as traffic, terrain, or driving style.
Real-World Mileage Feedback
Here is a more realistic perspective based on ownership evaluations, long-term test results, and vehicle forums:
| Driving Condition | Petrol MT | Petrol AT | CNG(CNG mode) |
| City | 12-14 km/l | 10-12 km/l | 18-20 km/kg |
| Highway | 16-18 km/l | 14-16 km/l | 22-24 km/kg |
| Mixed Driving | 14-16 km/l | 12-14 km/l | 20-21 km/kg |
For most consumers, the petrol manual version offers the best balance of power and efficiency, although the CNG version provides the best cost per kilometer.
What Affects Ertiga’s Mileage in Daily Use
Several driving and environmental factors have a huge impact on real-world mileage:
- City Traffic: Mileage is reduced by stop-start circumstances, frequent idling, and slow-speed driving.
- Transmission Type: Automatics burn more fuel in traffic, especially in older torque converter systems.
- Fuel Type: CNG burns cleaner and costs less, but it might cause engine performance loss and requires careful tuning.
- Tyre pressure: Underinflated tyres increase drag and lower mileage.
- AC Usage: Particularly in urban settings, AC use can lower mileage by up to 1.5 km/l.
- Driving technique: Rash acceleration and regular gear changes consume more fuel.
- Vehicle Load: A fully loaded MPV with luggage adds weight, therefore lowering efficiency.
- Road Gradient: Inclined and hilly roads lead to higher fuel usage.
- Maintenance: Fuel efficiency is affected by postponed servicing, clogged air filters, or incorrect wheel alignment.
Variant-Wise Mileage Comparison
Here’s a simple breakdown of how each Ertiga variant fares in real-world mileage:
| Variant | Fuel Type | Mileage | Transmission |
| LXi | Petrol | 20.51 km/l | Manual |
| VXi | Petrol | 20.51 km/l | Manual |
| VXi CNG | CNG | 26.11 km/kg | Manual |
| ZXi | Petrol | 20.51 km/l | Manual |
| VXi AT | Petrol | 20.30 km/l | Automatic |

| ZXi AT | Petrol | 20.30 km/l | Automatic |
| ZXi Plus AT | Petrol | 20.30 km/l | Automatic |
Verdict
- Best mileage: Ertiga CNG
- Best petrol efficiency: Manual versions
- Most practical, but less effective: Petrol Automatic
