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.

Consumer Reports no longer recommends Honda Civic

Consumer Reports annual Car Reliability Survey is out, and yes, there are some big surprises. First and foremost? The venerable publication no longer recommends the Honda Civic. In fact, aside from the walking-dead CR-Z and limited-release Clarity fuel-cell car, the Civic is the only Honda to miss out on CR's prestigious nod. At the opposite end there's a surprise as well – Toyota and Lexus remain the most reliable brands on the market, but Buick cracked the top three. That's up from seventh last year, and the first time for an American brand to stand on the Consumer Reports podium. Mazda's entire lineup earned Recommended checks as well. Consumer Reports dinged the Civic for its "infuriating" touch-screen radio, lack of driver lumbar adjustability, the limited selection of cars on dealer lots fitted with Honda's popular Sensing system, and the company's decision to offer LaneWatch instead of a full-tilt blind-spot monitoring system. Its score? A lowly 58. The Civic isn't the only surprise drop from CR's Recommended ranks. The Audi A3, Ford F-150, Subaru WRX/STI, and Volkswagen Jetta, GTI, and Passat all lost the Consumer Reports' checkmark. On the flipside, a number of popular vehicles graduated to the Recommended ranks, including the BMW X5, Chevrolet Camaro, Corvette, and Cruze, Hyundai Santa Fe, Porsche Macan, and Tesla Model S. Perhaps the biggest surprise is the hilariously recall-prone Ford Escape getting a Recommended check – considering the popularity of Ford's small crossover, this is likely a coup for the brand, as it puts the Escape on a level playing field with the Recommended Toyota RAV4, Honda CR-V, and Nissan Rogue. While Ford is probably happy to see CR promote the Escape, the list wasn't as kind for every brand. For example, of the entire Fiat Chrysler Automobiles catalog, the ancient Chrysler 300 was the only car to score a check – there wasn't a single Dodge, Fiat, Jeep, Maserati, or Ram on the list. That hurts. FCA isn't alone at the low end, either. GMC, Jaguar Land Rover, Mini, and Mitsubishi don't have a vehicle on CR's list between them, while brands like Mercedes-Benz, Volvo, Nissan, Lincoln, Infiniti, and Cadillac only have a few models each.

Editors' Picks March 2024: Refreshed Acura TLX, the Mazda CX-90 and more

This month, a wide variety of body styles and powertrain propositions earn Editors' Picks status. The brand-new Mazda CX-90 has impressed us in many forms, but that comes as no surprise. The Tonale from Alfa may not be a super-hot performance SUV like the Stelvio Quadrifoglio, but it's still captured our love.

It's a strong competitor in a big field. The available interiors put it on par with some real upscale brands. It's not perfect, but it's very good, and it's a good sign for future Mazdas."
