The H1 could deliver an average of 10 mpg. Rather, the H1 was built to provide exceptional off-road performance. This isn’t a big deal because the H1 was basically a military vehicle in civilian garb. However, most H1s were diesel-powered and delivered low mileage on the pavement. The 95 and 96 model years introduced gasoline-powered Hummers. The first trucks featured a naturally aspirated diesel engine while later models came with Turbo diesel motors. The Hummer H1 had the longest production run. Like its military cousin the Humvee, it is normal for the Hummer to be a gas guzzler. Considering the capabilities of the vehicle, there is no way to cut corners regarding its fuel consumption. In fact, the H3 delivers impressive fuel economy as we shall see in this article. But if you compare similar-sized trucks and their fuel efficiency, it’s easy to see that the Hummer is not an outlier. People marvel at the exceptional off-roading capabilities of the Hummer but complain about its fuel consumption.

If you are driving it at high speed, a Hummer H1 or H2 requires more fuel and oxygen to crank out higher horsepower. It is like driving a brick box and the vehicle experienced tremendous drag. They required a powerful engine to move their bulk and defeat daunting terrains. The Hummer, including the H1 which weighed over 8,000 pounds and the tamer H2s and H3s were heavy vehicles. Why Did the Hummer Have to Use So Much Gas? Achieving high speeds in such a truck requires the engine to burn more fuel to deliver the torque you need to reach your preferred pace. The truck is big and has a box-like design that creates a lot of drag. The slower your pace, the higher the number of miles you can get on a Hummer. Your driving habits can also affect the miles you can get from your Hummer. However, your fuel economy will improve with time. If you are keen on cutting fuel expenses, the Hummer is not the ideal vehicle for you because it’s size demands that the truck consumes a lot of gas. In fact, the few gas H1s have a lower range because of their smaller fuel tanks. There is no big difference between gas and diesel H1s regarding gas mileage.

The H1 gets around 10 mpg, the H2 a low 10-12 mpg while the H3 can deliver up to 14 mpg on average.
