You don't know if GM was talking about Hummer or Bolt when they were talking about 400 miles batter. You don't know how big (or small) the electric Hummer will be because it doesn't exist. GM didn't even show a picture and they didn't share any specs. Not to mention that Tesla's Cybertruck will be 500 miles next year, almost certainly with a battery smaller than 200 kW. No matter how you slice it, Tesla's cars are vastly more efficient today than what GM is hoping to do few years from now.
