Best and worst car brands of 2022 according to Consumer Reports

It's that time again, Consumer Reports this morning lifting the curtain on its 2022 Annual Car Brand rankings and its 10 Top Picks in the car, crossover, and truck category. Drumroll, please: This year, Subaru climbs two spots to claim the winner's circle, having come third the last two years. Last year, Mazda climbed three spots from 2020 to take the crown. This year, Mazda slipped to second, BMW taking the last spot on the podium, also a one-spot drop from 2021. Six automakers in the top 10 hailed from Japan, which is one more than last year, and five luxury makers occupied the top 10, which is two more than last year. And South Korean representation didn't crack the top this year, after Hyundai managed tenth last year. The seven makes after BMW are: Honda, Lexus, Audi, Porsche, Mini, Toyota, and Infiniti.  The magazine and testing concern says its Brand Report Card "[reveals] which automakers are producing the most well-performing, safe, and reliable vehicles based on CR’s independent testing and member surveys," and that "Brands that rise to the top tend to have the most consistent performance across their model lineups." The domestics also took steps back among the 32 OEMs ranked on the 2022 card. Chrysler and Buick were the domestic carmakers who made last year's top 10 in eighth and ninth, respectively. This year, Buick dropped to eleventh, Chrysler to thirteenth. Dodge went from fourteenth to sixteenth. CR continues to ding Tesla's yoke steerer, the not-exactly-natural handhold responsible for the electric carmaker going from sixteenth last year to twenty-third this year.

Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.
