The Maruti Suzuki Grand Vitara is one of the most fuel-efficient midsize SUVs available in India. One of the biggest reasons for this is the wide range of powertrain options available. Buyers can choose between a regular petrol engine, petrol automatic, ALLGRIP four-wheel-drive version, S-CNG and a strong-hybrid powertrain.
But which Grand Vitara gives the best mileage? And is the strong hybrid worth choosing over the regular petrol model if fuel efficiency is your main priority?
Here is a simple breakdown of the Grand Vitara mileage and fuel-efficiency ratings across different models.
Maruti Grand Vitara Mileage at a Glance
| Grand Vitara Model | Claimed Fuel Efficiency |
|---|---|
| Petrol Manual | 21.11 km/l |
| Petrol Automatic | 20.58 km/l |
| Petrol ALLGRIP | 19.20 km/l |
| Strong Hybrid | 27.97 km/l |
| S-CNG | 26.6 km/kg |
The figures above are claimed fuel-efficiency ratings. Actual mileage can be different depending on traffic, road conditions, driving style, air-conditioning use and the number of passengers in the car.
Grand Vitara Petrol Manual Mileage – 21.11 km/l
The regular petrol-manual version of the Grand Vitara offers a claimed fuel efficiency of 21.11 km/l.
This version uses the 1.5-litre K15C petrol engine with Maruti Suzuki’s Smart Hybrid technology. The system helps improve efficiency through features such as brake energy regeneration, torque assistance and idle start-stop.
For buyers who prefer a traditional manual gearbox, this version offers a good balance between purchase price, everyday performance and fuel economy.
The petrol-manual model may be a practical choice for someone who drives regularly on highways or has a mixed city and highway driving routine. It also offers better claimed mileage than the petrol automatic.
In simple terms, if you want a Grand Vitara with the familiarity of a petrol engine and manual gearbox but still want respectable fuel efficiency, the 21.11 km/l-rated petrol manual is worth considering.
Grand Vitara Petrol Automatic Mileage – 20.58 km/l
The petrol automatic version has a claimed fuel efficiency of 20.58 km/l.
This means the difference compared with the petrol manual is not very large on paper. The automatic version is especially suitable for buyers who spend a lot of time in city traffic and do not want to deal with frequent gear changes.
Of course, real-world mileage can vary considerably. In recent road testing by Autocar India, the petrol automatic returned 13.45 km/l under its test conditions, showing why buyers should treat official mileage figures as a benchmark rather than an exact guarantee for daily driving.
If driving comfort is more important to you than getting the highest possible mileage, the petrol automatic can make sense. However, buyers focused mainly on reducing fuel costs may find the strong-hybrid or CNG versions more attractive.
Grand Vitara ALLGRIP Mileage – 19.20 km/l
The Grand Vitara is also available with the ALLGRIP all-wheel-drive system on selected versions. Its claimed fuel efficiency is 19.20 km/l.
The lower mileage compared with the regular petrol versions is understandable. An all-wheel-drive system adds extra mechanical components and capability, which can affect overall efficiency.
However, the ALLGRIP version is aimed at a different type of buyer. It is more suitable for people who want additional traction and better capability on difficult roads or during occasional trips beyond regular city and highway driving.
So, while 19.20 km/l is the lowest claimed figure among the main Grand Vitara powertrain options, the ALLGRIP model offers something the other versions do not: the added benefit of an all-wheel-drive system.
If maximum mileage is your priority, the strong hybrid is the better choice. If you value extra driving capability, the ALLGRIP version could be worth the compromise in fuel efficiency.
Grand Vitara Strong Hybrid Mileage – 27.97 km/l
The Grand Vitara Strong Hybrid is the clear winner when it comes to claimed petrol fuel efficiency. It delivers a claimed 27.97 km/l, making it one of the most fuel-efficient SUVs in its category.
This version combines a petrol engine with an electric motor and battery. Unlike the mild-hybrid system in the regular petrol model, the strong-hybrid setup can use electric power to assist the vehicle more extensively and can operate in electric mode under suitable conditions.
The system can switch between petrol power, electric power or a combination of both, depending on the driving situation. It also recovers energy while slowing down and braking.
This is particularly useful in city traffic. Frequent braking and low-speed driving can allow the hybrid system to make better use of electric power, helping reduce petrol consumption.
According to a recent real-world test by Autocar India, the Grand Vitara hybrid returned 22.08 km/l on average. While this is lower than the official 27.97 km/l rating, it still highlights the strong hybrid’s significant efficiency advantage in everyday conditions.
The strong-hybrid model is therefore the best option for buyers who cover high monthly kilometres and want to save on petrol costs over the long term.
Grand Vitara S-CNG Mileage – 26.6 km/kg
For buyers looking to reduce running costs, the Grand Vitara S-CNG offers a claimed fuel efficiency of 26.6 km/kg.
It is important to remember that CNG efficiency is measured in km/kg, rather than km/l. Therefore, its figure should not be compared directly with petrol mileage in terms of the exact amount of fuel consumed.
The S-CNG version is a good option for people with easy access to CNG filling stations and a high daily running requirement. CNG generally offers lower running costs compared with petrol, although buyers should consider their local CNG infrastructure before making a decision.
The Grand Vitara S-CNG is available with a manual gearbox. Maruti Suzuki states that the model uses a 1.5-litre engine and offers the 26.6 km/kg claimed fuel-efficiency figure.
For buyers who drive extensively and have convenient CNG availability, this could be one of the most economical versions to own.
Which Grand Vitara Model Offers the Best Mileage?
The answer depends on what type of fuel you prefer.
For the highest petrol mileage: The Grand Vitara Strong Hybrid is the best choice with a claimed rating of 27.97 km/l.
For lower running costs with CNG: The Grand Vitara S-CNG offers a claimed 26.6 km/kg.
For a balance of simplicity and good mileage: The regular petrol manual delivers 21.11 km/l.
For city driving convenience: The petrol automatic offers 20.58 km/l while making stop-and-go driving easier.
For extra traction and driving capability: The ALLGRIP version delivers 19.20 km/l and adds all-wheel-drive capability.
What Affects Grand Vitara’s Real-World Mileage?
Official fuel-efficiency ratings are achieved under standardised test conditions. In real life, your Grand Vitara may deliver higher or lower mileage depending on several factors.
Heavy traffic usually increases fuel consumption, especially in a regular petrol car. Frequent hard acceleration and sudden braking can also reduce efficiency. Constant use of the air conditioner, steep roads, carrying heavy loads and low tyre pressure can further affect mileage.
On the other hand, smooth acceleration, maintaining proper tyre pressure and avoiding unnecessary idling can help improve real-world fuel economy.
The strong-hybrid version can be particularly effective in slow-moving city traffic because its electric system can support the petrol engine and recover energy during braking. Maruti Suzuki explains that its hybrid technology is designed to operate using petrol power, battery power or a combination of both, depending on driving conditions.
Final Verdict: Which Grand Vitara Is the Most Fuel-Efficient?
The Maruti Grand Vitara Strong Hybrid is the most fuel-efficient petrol model in the lineup, with a claimed rating of 27.97 km/l. It is the best option for buyers who want to maximise petrol savings, especially if they drive regularly in city traffic.
The S-CNG version, rated at 26.6 km/kg, is another strong option for reducing day-to-day running costs, provided CNG stations are easily accessible.
Meanwhile, the petrol manual and automatic versions remain practical choices for buyers who want a simpler ownership experience. The manual delivers a claimed 21.11 km/l, while the automatic is rated at 20.58 km/l.
Ultimately, the right Grand Vitara depends on your driving pattern. If you drive long distances or cover high monthly kilometres, the strong hybrid or CNG version could help save more on fuel. If you want lower upfront complexity and a conventional petrol experience, the regular petrol models still offer competitive efficiency for a midsize SUV.
Before making a buying decision, it is also worth checking the exact mileage figure for the specific variant you are considering, as fuel efficiency can vary depending on the engine, transmission and drivetrain. The current official Grand Vitara range includes petrol, strong-hybrid, CNG and ALLGRIP options with different claimed ratings.
