Most EV owners use Level 2 chargers at home, which typically add about 20–30 miles of range per hour. Full charges usually take 6–10 hours overnight, depending on your battery size and starting point. The Hummer EV, with its massive battery, may take closer to the 10-hour range, while the Sierra EV will likely be a bit faster.
Quick tip: You don’t have to charge from 0% to 100% every night — most owners just “top off” like you do with a smartphone.
Absolutely — the Sierra EV and Hummer EV are designed with towing in mind. Both offer strong towing capacities (up to 9,500 pounds for Sierra EV and up to 7,500 pounds for Hummer EV). However, towing reduces range — usually by about 30-50% depending on weight, terrain, and speed.
Real world example: If you normally get 300 miles of range, heavy towing might cut that down to 150–200 miles, so you’ll plan for a few more stops if you’re taking long trips.
Yes, but it’s manageable. Cold weather can temporarily reduce range by about 15–30%, because batteries work less efficiently at low temps and because cabin heating draws extra power.
Good news: Both the Hummer EV and Sierra EV have battery pre-conditioning features. That means if you plug in at home, your EV can warm up the battery before you hit the road, minimizing cold-weather range loss.
Pro tip: Precondition your EV while it’s plugged in — it uses power from your house, not your battery.
