This is an incredibly misleading article They conveniently left out the fact that GM's proposed battery for their 400 mile car is double the size of the battery Tesla currently uses to get 390 miles. GM said that they will offer a 200 KWh battery that will give their vehicle 400 miles of range at some point in the next year or two. You can buy a Tesla today with a 100 KWh battery that get 390 Miles of range. This isn't a positive thing for GM it means their cars are going to be more expensive for the same range.

Maybe, but GM is also planning to use that battery for their electric Hummer, which is a significantly bigger car than any Tesla. Teslas have weird, non-mainstream shapes to boost efficiency. I’d also note that Tesla EPA range is extremely aggressive (they set their own dyno multipliers) while other EV manufacturers are more conservative. That means roughly 75% range for Teslas in the real world.

  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.

  To second this, on a closed loop track at constant 75mph, Car and Driver found that the Taycan Turbo S (EPA 192mi) and Model S Performance (EPA 326-346 mi) had similar range in real-world testing. You can probably argue with the methodology but achieving Tesla's 70% EPA range advantage would not have been realistic in that test.

    The Taycan is double the cost of the Model S so even if they are the same range under this one use case which is probably not typical driving for many mean the Taycan is over priced for it's capabilities at best.
