However, time wasn’t kind to the original Hummer models. The original Hummer H1 of the 1990s was an 8,000 lb monster that only got 10 MPG. But despite that reputation, the Hummer garnered a loyal fanbase, leaving many drivers devastated when it was discontinued. Even before fuel costs were making front-page news, the Hummer models of the past were under harsh scrutiny for how little mileage they got out of a tank of gas. When GMC decided to revive the Hummer, it knew the challenge would be shattering the stigma around this gas-guzzling giant.
