2026 GMC Hummer EV SUV — GMC’s flagship all-electric off-road SUV: 

🔋 EPA Electric Efficiency (MPGe)

Because the Hummer EV SUV is a battery-electric vehicle, fuel "economy” is expressed in MPGe (miles per gallon equivalent):

• EPA City / Highway MPGe:
  • ≈ 59 MPGe city
  • ≈ 46 MPGe highway
  • ≈ 53 MPGe combined (approximate balance of city and highway) 

EV MPGe numbers tell you how efficiently the vehicle uses electrical energy compared with gasoline energy — higher MPGe means better efficiency. City MPGe is typically higher due to regenerative braking helping recapture energy at lower speeds. 

📏 EPA-Rated Electric Range

• EPA Estimated Range:
  • ~315 miles per full charge for the standard 2X trim. 
  Other trims (like the 3X) tend to have very similar range (~312 miles) with standard wheels/tires; using off-road/mud-terrain tires can lower it into the high-200s. 

🧠 What This Means

• City driving: With frequent stopping, regenerative braking helps efficiency, so the MPGe city figure (≈ 59) will be noticeably better than highway. 

• Highway driving: At sustained highway speeds, energy consumption rises, so MPGe highway (≈ 46) is lower than city. 

• Range: Around 315 miles EPA range is a strong number for an EV SUV of this size, but real-world range can vary with speed, temperature, and terrain. 

🔌 Note: Electric vehicles don’t use gallons of fuel, so MPGe and range give a better sense of real-world efficiency and how far you can drive on a charge.

If you’d like, I can break down the charging times (Level 2 vs DC fast-charging) or compare how this SUV’s efficiency stacks up against other large EV SUVs (like the Rivian R1S or Tesla Model X).
