how bad is the gas mileage on a 2005 hummer h2?

Question

Accepted Answer

Not great, honestly—but you probably expected that with a 6.0L V8 pushing over 6,400 pounds of truck!

Here are the official numbers for the **2005 Hummer H2 SUT**:

**EPA Ratings:** **10 MPG city / 13 MPG highway**

**Real-world data:** Based on tracking from actual H2 owners (nearly 200k miles of fuel-ups), you're looking at about **10 MPG combined** in the real world—some folks see as low as 9 MPG, others might touch 12-13 on a long highway cruise.

**What that means practically:**
- **Range:** ~320 miles city, ~415 miles highway on a full 32-gallon tank
- **Fuel cost:** About **$0.40 per mile** at today's ~$4/gallon prices
- **Annual cost:** Roughly **$4,800/year** if you drive 12,000 miles

To put it in perspective, that's about **4-5x the fuel cost** of something like a Toyota Camry Hybrid. But hey, nobody buys an H2 for the MPGs—they buy it for the presence, capability, and that unmistakable Hummer attitude!

The 6.0L V8 (LQ4) in your SUT is a stout, proven GM truck engine, so it's reliable, just thirsty. For a weekend toy or occasional duty, the fuel costs might be totally manageable. For daily driver duty... well, let's just say you'll get to know your local gas station attendant pretty well!

Want me to show you some more fuel-efficient alternatives, or are you committed to the H2 lifestyle? I can also pull up similar H2s if you want to compare pricing!
