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.

Full 2016 Mazda MX-5 Miata pricing released

Take heart, roadster fans. The first 2016 Mazda MX-5 Miatas due for the US are now in production. To go along with that milestone, the Japanese automaker has finally released full pricing for the fourth-generation Miata. As previously revealed, the 2016 Miata in the base Sport trim starts at $24,915 (plus $820 destination), and for that outlay buyers get a 2.0-liter four-cylinder making 155 horsepower and 148 pound-feet of torque that's matched to a six-speed manual. The convertible comes standard with features like LED lighting and a Bluetooth-equipped audio system. For $1,075 more on all models, customers can spec a six-speed automatic gearbox, and keyless entry is another $130 but standard with the auto 'box. One rung up is the Club trim for $28,600, and it improves things with 17-inch wheels, a more aggressive body kit and a seven-inch touchscreen infotainment system. Order the manual trans, and the roadster gets a limited-slip differential, Bilstein dampers and a shock-tower brace. There's also a $3,400 package to make this version of the convertible even sportier with 17-inch BBS wheels, Brembo front brakes, side sill extensions and a rear bumper skirt. Among the regular trims, the top rung is the Grand Touring for $30,065 that adds luxuries like heated, leather seats, automatic climate control, rain-sensing wipers, and adaptive headlights. Mazda's i-Activesense is also standard and includes blind spot monitoring, rear cross-traffic alert and lane-departure warning. Finally, there's the Launch Edition, which is limited to 1,000 units, and it sells for $30,495 (or $31,570 for an automatic). All of them come in an exclusive combo of Soul Red with Sport Tan leather, and buyers get all of the Grand Touring's kit, plus standard keyless entry. The order site for these special roadsters opens on May 5, but hopefuls can pre-register now for a reminder. The first 2016 Miatas should hit dealers in late summer. That should provide some time for top down driving fun before it gets too cold.

Recharge Wrap-up: BlaBlaCar raises $100M, NASA launches CO2 satellite

BlaBlaCar, a ridesharing startup in Europe, has raised $100 million in a funding round led by Index Ventures. After recently growing to 12 countries and 8 million users, BlaBlaCar plans to us the funding for even more aggressive growth throughout Europe. The ridesharing service pairs drivers and passengers, allowing passengers to catch rides between cities while allowing drivers to save money on fuel on road trips. Drivers are not allowed to make a profit, and are only allowed to charge enough to break even after BlaBlaCar takes its percentage, to keep costs low for everyone involved. BlaBlaCar doesn't currently have plans to break into the US. Read more at The New York Times or at Gigaom. NASA has launched its Orbiting Carbon Observatory-2 into space to keep track of carbon dioxide in Earth's atmosphere. After being delayed on Tuesday, the Delta II rocket equipped with an instrument to measure CO2 launched from Vandenberg Air Force Base in California at 5:56 am on Wednesday. It is ultimately headed for a polar orbit to watch how CO2 levels rise and fall throughout the seasons, in part to try to figure out if the land and oceans will continue to be able to absorb half of carbon emissions. The mission will last two years, and should give further insight into climate change. Learn more in the video below, at NASA or at New York Times. Mazda is likely to release a plug-in version of its Mazda2 hatchback with a rotary range extender, reports Australian site Motoring. The electrified Mazda2, and any other future Mazda EVs and hybrids, will likely be limited to markets with government subsidies for such vehicles (which doesn't include Australia) says Mazda Australia Managing Director Martin Benders. "As the best possible fuel economy at an affordable price hybrid doesn't make sense, because the fuel economy gain isn't that great unless half of all sales are hybrid, which won't happen without big tax breaks like in the Netherlands," said Benders. That doesn't rule out the US, though. A prototype version of the range-extended Mazda2 featured a 0.33-liter rotary engine to provide power to the lithium-ion battery pack when depleted. A 2.6-gallon gas tank essentially doubled the electric Mazda2's driving range to 250 miles. Read more at Motoring. Zap plans on selling 1,000 Urbee EVs per month to SunRa for distribution in China.
