    Now I’m confused, WLTP is measured at a certain temperature. Since the Polestar and the Tesla made it the same distance, shouldn’t they have the same WLTP range?

    Does the Polestar just perform better at lower temperatures? Does the Polestar also exceed its rated range in summer then?

        Is the WLTP range not checked by any authority?

        Since the testing environment is pretty clear I would have assumed that there is a central authority that tests the claims and reprimands the manufacturer if the claims are off by too much.

            I don’t know many car-related EU and national authorities that can be ignored by the manufacturer without consequences. Otherwise we would have manufacturers that lie about the size, weight, capacity, speed limits and acceleration of their cars to pad their numbers.

                Did you forget the whole diesel emissions scandal? A ridiculous amount of car manufacturers were caught after it turns out they were lying on the tests for years at that point.

                That’s different. They were not just lying, they were cheating. If they had given them the wrong emission values in the first place they would not have been allowed to sell their cars in the EU.

              The car manufacturers have to publish results from standardized tests for range, fuel economy, battery capacity, etc.
              The regulations for those test regimes are largely written by “industry experts” (i.e. lobbyists employed by the car manufacturers).
              Then they program the engine management chips in their cars to recognize when the car is on a test stand and go into extreme efficiency mode.
              There was a scandal about this a couple years ago with VW and they got some flak for it. By now it’s come out that all manufacturers do this, but the outrage is gone, it’s accepted as just another fact of big business.
