Mazda heads to Daytona with fierce-looking Mazda3 TCR race car

Hatchback lovers rejoice, Mazda has turned its stunning five-door into a race car. The Mazda3 TCR will participate in the 2020 IMSA Michelin PilotChallenge and will first debut in January 2020 during the Rolex 24 weekend in Daytona, Florida. Mazda is set to return to touring-car racing (TCR) with an adaptation of its popular compact car. The Mazda3 TCR has a lot of exterior changes that make it visually different from its road car brethren, and a whole lot more performance alterations we can’t see. A massive wing stands tall at the rear, and itÂ’s matched with a bulbous widebody kit with cooling vents behind the front and rear wheels. The new dress also has a front splitter, side skirts, and rear bumper aero. Further enhancements include a new hood, a single centered exhaust pipe, and new wheels and tires. Under the hood, the Mazda3 TCR has a turbocharged four-cylinder engine that makes 350 horsepower. It pairs with a six-speed transmission with paddle shifters. Mazda collaborated with the same company that manufacturers the Global Mazda MX-5 Cup Car, Long Road Racing, to develop the TCR. It is homologated for global racing in 36 TCR championships, and it will make its debut at the four-hour Endurance Challenge at the Daytona Rolex 24.  

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.
