Sure, for a specific car, but Samsung isn’t making cars, just a battery that could go in a number of different vehicles. So all we’re really able to compare is batteries, not full vehicle efficiency.

If they’re intending to suggest this new battery, when fitted in an existing EV (say a Model Y) would result in a 600 mile range, then it’s interesting, but all other things (drivetrain, drag, vehicle weight) would have to remain constant.
