Maruti Grand Vitara Mileage 2026: Petrol, CNG and Strong Hybrid Explained

Fuel efficiency is one of the biggest strengths of the Maruti Suzuki Grand Vitara, especially if you choose the strong hybrid or CNG version. The SUV is available with petrol, strong hybrid and CNG powertrains, giving buyers several options depending on their budget and daily running.

The Maruti Grand Vitara mileage ranges from 19.20 km/l to 27.97 km/l for the petrol-powered versions, while the CNG version delivers up to 26.6 km/kg. However, real-world mileage can be quite different from the official figures. In this guide, we look at the ARAI-certified Grand Vitara mileage and compare it with real-world road tests and owner-reported fuel economy.

Grand Vitara Mileage at a Glance

The Grand Vitara Strong Hybrid is the most fuel-efficient version, with an ARAI-certified figure of 27.97 km/l. The CNG version is another good option for buyers looking to keep everyday running costs low.

Grand Vitara Petrol Mileage

The regular Grand Vitara uses a 1.5-litre petrol engine and is available with manual and automatic transmission options. The official mileage is 21.11 km/l for the manual and 20.58 km/l for the automatic.

Petrol Manual Real-World Mileage

The petrol manual can deliver good fuel economy, but the actual number depends heavily on traffic and driving style.

Current user-reported figures on major automotive websites are around 18 to 19 km/l. CarWale, for example, lists owner-reported mileage of around 18 to 19 km/l across several manual variants.

In heavy city traffic, the number can be lower. On open highways, a light right foot and steady speeds can push the mileage above 20 km/l.

For everyday use, around 15 to 19 km/l is a sensible real-world range to expect from the petrol manual, depending on how and where you drive.

Grand Vitara Automatic Mileage

The 1.5-litre petrol automatic has an ARAI-certified mileage of 20.58 km/l, but controlled road tests show a much larger difference between the official figure and everyday fuel economy.

Autocar India recorded:

• City: 11.60 km/l
• Highway: 15.30 km/l
• Average: 13.45 km/l

Another road test by CarDekho returned 13.72 km/l in the city and 19.05 km/l on the highway.

These results show just how much traffic and driving conditions can affect the Grand Vitara automatic. A reasonable expectation is around 11 to 14 km/l in city driving and 15 to 19 km/l on the highway.

The automatic is therefore more about convenience than maximum fuel savings. If most of your driving involves crowded city roads, its smooth torque-converter gearbox can still make it worth considering.

Grand Vitara Strong Hybrid Mileage

If fuel efficiency is your main priority, the Grand Vitara Strong Hybrid is easily the most interesting version.

Its 1.5-litre petrol engine works together with an electric motor and battery. At low speeds and under light loads, the SUV can run on electric power for short periods. It also recovers energy while slowing down and uses that energy to recharge the battery.

The official ARAI mileage is 27.97 km/l, but even its real-world figures are impressive.

In Autocar India’s controlled test, the Grand Vitara Strong Hybrid returned:

• City: 23.77 km/l
• Highway: 20.39 km/l
• Average: 22.08 km/l

CarDekho recorded even better results, with 25.45 km/l in the city and 21.97 km/l on the highway.

Based on these tests, around 22 to 24 km/l in mixed driving is a reasonable real-world expectation, although some owners report higher numbers under favourable conditions.

Interestingly, the strong hybrid can be more efficient in city traffic than on the highway. Frequent slowing and braking allow the hybrid system to recover energy, while the electric motor can handle some low-speed driving without using petrol.

Grand Vitara CNG Mileage

The Grand Vitara CNG has an ARAI-certified fuel efficiency of 26.6 km/kg.

Real-world figures are lower and vary depending on traffic, AC use, vehicle load and driving style.

CarWale currently lists owner-reported CNG mileage at around 18.25 km/kg. Other owner reports also show considerable variation depending on driving conditions.

For everyday driving, around 18 to 22 km/kg is a reasonable expectation. Highway mileage can cross 20 km/kg when the SUV is driven at a steady speed.

The main advantage of the CNG version is its lower running cost compared with petrol. However, buyers should also consider CNG availability in their area and the effect of the CNG cylinder on luggage space.

ARAI vs Real-World Grand Vitara Mileage

Here is a simple comparison of the official figures and what you can reasonably expect in everyday driving.

These real-world numbers are not official figures. They are approximate ranges based on independent road tests and owner-reported mileage. Your actual fuel efficiency can be higher or lower.

Why Does Real-World Mileage Differ From ARAI Mileage?

ARAI mileage is measured under standardised testing conditions. Everyday driving is much less predictable, which is why your dashboard mileage may look very different from the brochure figure.

Several factors can affect Grand Vitara mileage:

• Heavy traffic and frequent stop-start driving
• Regular use of the air conditioner
• Aggressive acceleration and braking
• Driving at high speeds on the highway
• Carrying extra passengers or luggage
• Incorrect tyre pressure
• Road conditions and gradients
• Short journeys where the engine does not reach its ideal operating temperature

The effect is slightly different with the strong hybrid. Stop-start traffic gives the hybrid system more opportunities to use its electric motor and regenerative braking, which is why its city efficiency can be particularly impressive.

Which Grand Vitara Gives the Best Mileage?

The Grand Vitara Strong Hybrid gives the best overall mileage. Its official figure of 27.97 km/l is the highest in the range, and independent real-world tests show that it can return around 22 to 24 km/l in mixed driving.

The Grand Vitara CNG is worth considering if your priority is low fuel cost and you have easy access to CNG stations. Real-world efficiency of around 18 to 22 km/kg can make it economical for buyers with high monthly running.

The petrol manual is the simpler choice for buyers who do not drive enough to justify paying extra for the strong hybrid. It can also deliver impressive highway mileage when driven carefully.

The petrol automatic offers the convenience of a torque-converter gearbox, but its real-world city mileage can be considerably lower than the official ARAI figure.

Ultimately, the right choice depends on your usage. For heavy city driving, the strong hybrid makes a strong case. For buyers focused on low running costs, CNG is worth considering. For moderate use and a lower purchase price, the regular petrol remains a practical option.
