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.

Jeremy Clarkson chooses his top 10 cars for 2015 and 2016

Jeremy Clarkson is well-known for his role as co-host on the old Top Gear. But the frontman of the upcoming Amazon Prime Show, The Grand Tour, also has a standing column for The Sunday Times in the UK where he reviews the latest cars. With fall nearing, Clarkson put out a list of his top-10 cars from this year and 2015. Some on the list will surprise you, while others represent everything we've come to love about Clarkson. In order to make his list of star cars, the vehicles must offer what co-host James May calls "the fizz." The vehicles, Clarkson claims, have something that is out of the ordinary. Whether it's the car's looks, the way it gets up to speed, or its high-tech gadgets, Clarkson's top-10 list is made up of items that are more than just tools for getting from point A to B. So which ones made the list? Head over to the column in The Sunday Times.

2016 Mazda MX-5 Miata configurator fulfills your droptop dreams

The first batch of 2016 Mazda MX-5 Miatas are already at dealers, but Mazda is finally launching a configurator for its completely revised sports car. Even if pricing doesn't come as a surprise, you can still have some fun creating one to your own specific tastes. The major equipment changes on the Miata happen between the Sport, Club, and Grand Touring trims, and options are generally kept light. The real standout is the Brembo/BBS package for $3,400 that's exclusive to the Club version. It adds Gunmetal 17-inch BBS wheels, Brembo front brakes with red calipers, side sill extensions, a rear bumper skirt, and keyless entry. On the Sport and Grand Touring, $1,200 buys the Appearance Package with a front air dam, side sill extensions and rear bumper skirt. There's also keyless tech for $130 on them. Mazda also offers a few items to dress up the convertible's looks. There's a choice of a black or body color rear lip spoiler for $350, and Soul Red Metallic paint adds $300. For protection, clear film for the front and rear paint is $125, all-weather floor mats go for $90, and wheel locks cost $55. Finally, a cargo net is $50. We ticked every applicable box on the Club trim above to make its $28,600 base price leap to $33,790, after the $820 destination charge on all models. Happy building. Related Video:
