Hummer Gas Mileage : Here’s Fuel Economy & Everything You Need To Know About

Hummer Gas Mileage : Here’s Fuel Economy & Everything You Need To Know About

Since the years it was produced, Hummer gas mileage has had a reputation of its own. Its iconic features made it a popular choice among SUV (Sport utility vehicle) enthusiasts.

The one downside of this utility vehicle is that it’s not fuel-efficient and consumes too much fuel as this car possesses a gas-guzzling engine.

Emphasizing upon the mileage of Hummer, it generally depends on various parameters that influence its mileage.

These factors include the production year, model, type of engine, driving ethics, the road it is plying on. The latest version of this brand, H3, can deliver an average mileage of 14 mpg.

The previous versions have much less mileage than the newer ones. The later variants of Hummer are also better in terms of lower friction rates and better torque.

Still, the gas mileage of these iconic cars is being criticized since the very inception of their launch in the USA and other countries around the globe.

Nevertheless, if you are brilliant at the wheels, you will feel that your Hummer is slowly improving upon its fuel efficiency and hence the mileage.

Hummer does not encourage rush driving as your driving speed will automatically lower the mileage. Slow but steady wins the race!

What’s the average hummer gas mileage?

Although the mileage of Hammer is solely dependent upon several factors, an approximate average mileage will help its consumer to buy the vehicle of their choice.

Well, H1 has an average mileage of 10 miles per gallon (4.25 kilometers per liter). The Hummer H2 is slightly better at 12 Miles per gallon (5.10 kmpl).

The hummer H3 delivers a mileage of up to 14 mpg (5.95 kmpl). The Hummer H2 has a mileage of about 3.5 kilometers per liter in the city street to break down the mileage more in detail.

This car delivers a mileage of about 4kmpl along the highways. When it comes to hummer H3, it provides a mileage of 3.5 kmpl in the city and about five kmpl along the road.

Looking at the statistics, it is evident that this car is not a fuel-friendly off-roader.  Apart from gasoline, the diesel version is also available.

Yet, there is barely any difference between a gasoline-driven Hummer and a diesel-driven Hummer. Either way, it is incapable of saving your money if your eyes are all set on getting this SUV and driving in some offbeat terrains.

If you are not a car enthusiast, going for a Hummer must be considered a wrong choice. You are advised to go for a car that suits your fuel budget.

Hummer is for those who are genuinely passionate about off-road driving and taking their driving skills a notch higher than the rest of the crowd.

Do hummers take up a lot of gas?

Due to its heavyweight (around 7000 pounds on average) and bulkiness, it naturally needs a powerful machine to pull itself into rugged terrains.

Hummer is an absolute off-roader, and it’s unexpected for an off-roader to be highly fuel-efficient and not to take up a lot of gas. Due to its high performance and offbeat driving features, it lags a bit into fuel consumption.

Few drivers commented on its not-so-enriched aerodynamics. Poor dynamics are limited to the previous versions of the SUV, i.e., H1 and H2. The H3 is a lot more fuel-efficient and delivers a smooth driving experience too. It requires less oxygen to propel high horsepower.

If you are determined to cut your fuel costs, then Hummer is not the perfect car to fulfill your daily commuting needs.

Your fuel economy will gradually improve with time and constant driving habits. Sometimes, your driving behavior affects the fuel efficiency of your vehicle.

Achieving speed by reckless driving often results in the burning of more fuel and premature damage to the engine.

Why are hummers so bad on gas?

Weight and poor aerodynamics ruin its possibility of retaining its fuel. The friction makes the entire scenario even worse.

Since aerodynamics is a vital decider for mileage, its poor aerodynamics can never lead to less fuel consumption.

At around 7 feet breadth, it’s a huge car for the engine to pull. Hence, the pulling takes a lot of gas in the first place. In case you prefer speed, this utility vehicle is a pure piece of disappointment.

As soon as you start accelerating, it starts guzzling the gas at a high rate. A specific modification of the engine and the other essential parts to reduce its friction would have made Hummer a bit more reliable in its gas consumption.

But yes, with the new models, the manufacturers are paying attention to this defect and constantly working on improving its fuel efficiency.

If you divert your focus from this mileage feature for a while, you will find out that Hummer is a great car compared to the other off-road vehicles.

Its off-roading performance is truly unique. But this slightly negative aspect of poor fuel efficiency makes it a poor choice for investing in a perfect SUV.

Hummer H2 fuel economy

The Hummer H2 is slightly smaller than the H1. Naturally, the size of the engine is smaller and occupies less space due to its compact design.

Although its engine is quite impressive, it fails to influence the customers regarding its fuel consumption role.

A survey was done among the Hummer H2 users in the USA. It was later found that the vehicle has a mileage of around 11 mpg.

This may go up to approx. 12.5 mpg based on the production year. There is no comprehensive data available on the mileage it delivers.

With slight modifications on H2, the manufacturer came up with the H2 SUT. It had an average mileage of 12 mpg for an extended period of the journey.

This vehicle is hefty and 6000 pounds. It’s unlikely it will ever be considered a fuel economy car in the modern automobile market.

Still, it has to be admitted that the company is modifying its features with each new launch.

Hence, we foresee a Hummer that ticks all the right boxes shortly. Despite being a gas guzzler, it is still a favorite among passionate off-roader enthusiasts.

Hummer H3 fuel economy

Hummer is constantly trying to improve to retain its buyers by focusing on the fuel economy aspects with each variant.

Compared to H2, it weighs much less. At around 4700 pounds, the aesthetic of this off-roader started impressing its consumers with its fuel efficiency.

The modifications indeed won back its buyers with improved aerodynamics, less friction with the road, and a smaller engine that does not consume too much gas.

As stated earlier, Hummer is always better and more impressive than its previously launched cars. With a smaller engine and better aerodynamics features, Hummer H3 is an absolute head turner as it always has its aesthetics to draw the prospective buyers.

The grille design, interior, and other features compensate for its lack of fuel efficiency.

Mileage should not bar you from getting a Hummer H3 if money is no bar for you. Just hit the road with this stunning SUV, and your driving is going to be worth every penny.

Hummer H2 gas tank size

Hummer H2 has a tank with a fuel capacity of 32 gallons or approximately 121 liters. Almost all H2 vehicles are powered by gasoline and cover over 400 miles when the tank is full.

Its size and its not-so-modified aerodynamics could not hamper it from delivering a decent mileage. Amidst all the complaints, it is still getting buyers because of the other features, which are incredibly satisfying and worth owning this vehicle.

Hummer H3 gas tank size?

With a smaller fuel tank, hummer H3 holds about 23 gallons (88 liters approximately). A full tank will cover a distance of a little less than 400 miles. With an average mileage of 15 mpg, it might be considered a good SUV.

After Hummer H2, this utility car has retained its consumers because it modified engines, aerodynamics, and other features responsible for its excessive fuel consumption.

How much does it cost to fill up a hummer tank?

The cost of filling a Hummer tank depends upon two factors. One is the size of the fuel tank, and the other factor is the price of gasoline (or your preferred fuel).

Considering the current rates of gasoline, it would cost around $108(8000 INR approx) to fill up a hummer H2 tank to the brim.

Whereas the H3 has a low fuel capacity of 23 gallons, it would cost around $78(5700 INR approx) to fill the tank.

It’s crystal clear that the fuel cost is pretty high compared to the mileage of these cars.

Ways to improve mileage

Sad but true, if fuel efficiency is what you are looking for in a car, Hummer will not satisfy your driving needs.

Although H3 might appear a tad different in the mileage segment, it is not unusual that it will not do justice to your fuel consumption expectation. If you are a lover of off-the-beaten-track driving, you ought not to focus on these cons.

Yet, the SUV fanatics with a soft corner for Hummer will find a way out to improve its mileage. Here are a few helpful tips just for you:

  • Lower your driving speed: It’s needless to say that you will easily be able to drive more miles without having to worry about refueling the tank by lowering your wheel rate. Well, yes, this might not be an easy tip to follow for those who prefer to hit the road at a relatively higher speed. The Hummers fuel co0nsumption is directly proportionate with its engine’s thrust for power. If you are still driving H1 or H2, you must pay extra attention to this golden rule. Its relatively poor aerodynamics makes it mandatory to move slowly to save some penny on gas.
  • Change the fuel: You might be bothered about your Hummer’s fuel consumption and not fining any specific cause of it. The culprit, in this case, could be your fuel. Certain additives present in power may limit its performance. You may need synthetic fuel to enhance your vehicle’s all-around performance, including excellent mileage.
  • Pump your tires at regular intervals: You can easily add a couple of miles of driving simply by keeping your tired inflated most of the time. It reduces friction, hence eats less gas.
  • Modify your SUV: A good quality exhaust will promise a smooth fuel-efficient drive for your favorite car. Removing the spare tire also contributes to the fuel-saving purpose as it reduces the weight of the vehicle. You may also get rid of the crossbars and other accessories that increase the car’s weight while at the same time having your safety in mind.
  • Switch to two-wheel drives: By saying yes to two-wheel enterprises, you reduce the load the engine has to bear by disconnecting certain parts of the car from the engine. Lesser the pack, the greater the mileage!

With these tips handy, you will always be able to add a few miles to your journey. But, in the long run, these tricks will not help you make a big difference.

Once you set your eyes on Hummer, you have to be a little considerate with the fuel consumption issue. If you are not going to part with the fuel economy feature of your car, you must go for a different SUV altogether.


Hummer gas mileage has been a cause of concern for many years. It is evident for car owners to bother about this particular feature before buying their favorite car.

Compared to the first two variants of Hummer, H3 is pretty decent with the fuel though it should not be a tempting factor for you to own the car.

The weight, heavy design, engine, and bulkiness contribute to its extra fuel consumption. With a few tricks, you may add up a mile to your journey, but that will not satiate your goal of saving money on fuel.

Overall, gas mileage cannot be a bar to define the car’s otherwise fantastic off-road features that attribute to its popularity among off-road fanatics.
