Yeah, and if you’re doing a lot of highway driving at high speeds, expect the range to drop even more. Wind resistance is no joke with something this big!Hummer EV range it's a tricky one! GM says 300+ miles but that's in perfect conditions. How you drive really changes things. Off-roading, towing, or fast driving will eat up the battery. Cold weather also takes a toll. Most owners are seeing around 250-300 miles in normal driving but it varies a lot. Remember it's a huge heavy EV, so it uses a lot of power.
