Not just in their own category, but among all new 2021-22 cars tested.
Some caveats: there are a lot of vehicles that were not tested for various reasons. The EV6 and Ioniq 5, for example, were only released after AAA's cutoff date of 1/1/22. And they didn't review any Teslas, for whatever reason. (Maybe Tesla didn't submit any vehicles for testing? I dunno.) But overall I think the ratings are pretty good and accurately reflect my opinion of the P8. (I never test drove a Mach-E because I didn't care for its looks and wanted the higher ground clearance of the Volvo.)
