Grand Vitara Mileage 2026 is one of the biggest reasons buyers consider Maruti Suzuki’s mid-size SUV. The Grand Vitara is available with petrol, CNG and strong-hybrid powertrains, giving buyers different options depending on their driving requirements.
According to the latest available mileage data, the Grand Vitara Strong Hybrid delivers an ARAI-certified 27.97 km/l, making it the most fuel-efficient version in the current range. The CNG version has a claimed efficiency of 26.6 km/kg, while the petrol variants deliver around 20.58–21.11 km/l, depending on the transmission.
Grand Vitara Mileage 2026: Variant-Wise Figures
| Grand Vitara Version | Fuel | Transmission | Claimed Mileage |
|---|---|---|---|
| Petrol Manual | Petrol | 5-speed MT | 21.11 km/l |
| Petrol Automatic | Petrol | 6-speed AT | 20.58 km/l |
| CNG Manual | CNG | 5-speed MT | 26.6 km/kg |
| Strong Hybrid | Petrol + Electric | e-CVT | 27.97 km/l |
These figures are ARAI-certified or manufacturer-claimed figures and should not be treated as guaranteed everyday mileage.
1. Grand Vitara Strong Hybrid Mileage
If maximum fuel efficiency is your priority, the Grand Vitara Strong Hybrid is the most interesting option.
It combines a 1.5-litre petrol engine with an electric motor and lithium-ion battery system. Maruti Suzuki officially lists 27.97 km/l mileage for the Strong Hybrid. The system can also operate in electric mode under suitable conditions, helping reduce petrol consumption in slow-moving traffic.
In real-world driving, mileage depends heavily on traffic, air-conditioner use, road conditions, driving style and battery assistance. Autocar India’s testing data says the Grand Vitara hybrid returned 22.08 km/l in its real-world test.
2. Grand Vitara CNG Mileage
The Grand Vitara CNG is another attractive option for buyers who want lower running costs.
Maruti Suzuki lists a claimed mileage of 26.6 km/kg for the CNG version. The CNG powertrain uses the 1.5-litre engine and is available with a manual gearbox.
However, real-world CNG mileage can be lower than the claimed figure because of traffic, tyre pressure, passengers, AC usage and driving habits.
3. Grand Vitara Petrol Mileage
For buyers who prefer a conventional petrol SUV, the Grand Vitara’s petrol-manual version has a claimed mileage of approximately 21.11 km/l, while the petrol automatic version is rated at around 20.58 km/l.
Autocar India’s real-world test of the petrol automatic returned 13.45 km/l. This shows why buyers should distinguish between ARAI figures and actual daily-use mileage.
Which Grand Vitara Gives the Best Mileage?
If we compare the three powertrains, the ranking is straightforward:
Strong Hybrid → 27.97 km/l
CNG → 26.6 km/kg
Petrol Manual → 21.11 km/l
Petrol Automatic → 20.58 km/l
Therefore, the Grand Vitara Strong Hybrid is the best choice for maximum claimed fuel efficiency, while CNG can be attractive for buyers focused on running costs.
Grand Vitara Mileage: What Can You Expect in Real Life?
Actual mileage will vary from driver to driver. City traffic usually reduces fuel efficiency compared with controlled ARAI testing. Frequent acceleration, heavy traffic, high-speed driving and continuous air-conditioner use can also increase fuel consumption.
For example, Autocar India’s testing recorded 13.45 km/l for the petrol automatic, while its real-world hybrid test returned 22.08 km/l.
Therefore, prospective buyers should look at both claimed mileage and independent real-world tests before making a purchase decision.
Is Grand Vitara Good for High-Mileage Driving?
Yes. The Grand Vitara offers one of the broadest fuel-efficiency choices in its segment. The Strong Hybrid is particularly suited to buyers who drive regularly in cities and want to reduce petrol consumption.
The CNG version can also make sense for high-kilometre users, provided CNG availability is convenient in their area.
Final Verdict
The Grand Vitara Mileage 2026 range is impressive. The Strong Hybrid leads with 27.97 km/l claimed mileage, followed by the CNG version at 26.6 km/kg. Petrol versions offer around 20.58–21.11 km/l claimed mileage, although real-world results can be considerably different.
For maximum fuel efficiency, the Strong Hybrid is the standout choice. For lower running costs, CNG is worth considering, while petrol remains the simpler option for buyers who prefer conventional powertrains.
Mileage varies according to traffic, driving style, vehicle load, tyre pressure, weather, AC usage and road conditions.
