That's... fairly generous to Edmunds. There was almost a 20 degree difference in temperatures between cars.
> How does Edmunds conduct its testing? The roads [...] driving around the greater Los Angeles area
Which can exaggerate the difference between cars. Suppose Car A has just enough battery to coast over the top of Angeles Forrest Highway and then regen down the other side. Car B rolls to a stop 1 ft from the top.
Most people would say these two cars have virtually the same range, but a test on hilly public roads could turn that into a 20+ miles difference in range.
- gamblor956 6y agoThey tested all of the cars in the same geographic location, following the same course on roads, highways, and freeways, ever time, during the same month. No other brand had the same systematic issue with overstated mileage despite the temperature differences, which affected all of the Teslas, not just the one driven during the coldest days (which were still no lower than 45 degrees F). Most people would say these two cars have virtually the same range, but a test on hilly public roads could turn that into a 20+ miles difference in range. That would have benefited Tesla, as their vehicles have larger batteries than their competitors. And yet...they systemically underperformed their EPA ratings.
