When Hummer’s H2 thundered into showrooms across the country in 2002, its 6.0-liter V8 returned somewhere between nine and 10 miles per gallon. It was among if not the least fuel-efficient passenger vehicles on the road at the time, all while the Toyota Prius was hitting its stride. At the end of the decade the recession began to set in and gas prices began to spike, signaling the end of the H2’s seven-year run.
Resurrected with an all-electric powertrain for 2022, the Hummer remains incredibly inefficient. And based on information currently available, will retain its title as one of the least efficient passenger vehicles on the market – albeit this time when benchmarked against its electron-using brethren. However, thanks to modern electric powertrains the Hummer’s energy consumption is still less than that of the most fuel-sipping gasoline-powered vehicles. We’ll break down the numbers.
In its highest trim, the Hummer is said to have a 200 kWh battery pack capable of delivering 350 miles on a charge translating to 572 Wh per mile. For comparison the 75 kWh battery pack in Tesla’s Model 3 Long Range delivers 353 miles of range, coming in at an industry-best 213 Wh per mile. Sapping two and a half times more than the Model 3 Long Range, GMC’s Hummer is still incredibly efficient when compared to gas vehicles. Stay with us.
The EPA rates the energy within a gallon of gasoline equivalent to 33.7 kWh of energy, meaning the Hummer’s energy consumption comes in at 59 mpg equivalent. Coincidentally this figure just eclipses that of the 2021 Prius Prime Eco, which comes in at 58 mpg city.
A lot can happen in 20 years, but we’d bet nobody predicted the Hummer would ever use less energy per mile than a Prius. We’re fully on board with the trajectory things are headed and cannot wait to see what another 20 years has in store.
