Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.

Updated Mazda6 Wagon to look lovely in Geneva

For the 2018 model year, Mazda updated the Mazda6 sedan with some design and mechanical tweaks. It will take the stand for its European debut at the 2018 Geneva Motor Show. There, it will be staged alongside the Mazda6 Wagon, which will be getting its own global debut at the Swiss expo. Unless there's some sort of miracle, we won't be getting the five-door version here in the United States, which is a shame, because it's a beautiful wagon. Customers here — apart from a handful of die-hard fans and, perhaps, the entirety of the American automotive press — prefer something with a bit more elevation to it. Ask a Mazda dealer in Michigan or Arizona for a Mazda6 Wagon, and they'll probably try to sell you a CX-5 instead. That frustrates the wagon fans. "It's gorgeous," said Autoblog Associate Editor Joel Stocksdale. "It kills me that we don't get it." The Mazda6 Wagon, like the new sedan, features an updated exterior and interior design, new seating, better performance, and improved driving dynamics. The Mazda6 Wagon will be on the show floor with a number of other beautiful cars, including the Mazda Kai and Vision Coupe concepts, which bowed at the Tokyo show. Mazda will also showcase its new gasoline-powered Skyactiv-X spark controlled compression ignition, which we were recently able to test in a prototype vehicle.

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.
