Mazda and Toyota formally announce plans to 'make cars better'

Following Monday's report that Toyota and Mazda could be expanding their cooperation, the two Japanese automakers have made it official, issuing a joint press release announcing a "mutually beneficial long-term partnership" that will "make cars better." The two companies will set up a joint committee to figure out the strengths and weaknesses of each party. As we explained yesterday, that likely means Mazda will benefit from Toyota's plug-in-hybrid and fuel-cell tech, while the world's largest automaker can take advantage of the Zoom-Zoom automaker's line of efficient Skyactiv engines. "I am delighted that our two companies can share the same vision and work together to make cars better. I can think of nothing more wonderful than showing the world – together – that the next 100 years of cars will be just as fun as the first," Toyota President Akio Toyoda said in the attached joint statement. Mazda President and CEO Masamichi Kogai echoed that sentiment, saying: "I hope that by working together to make cars better, we can raise the value of cars in the eyes of consumers while also enhancing the manufacturing capabilities of our home, Hiroshima, and all the communities we are involved in as well." Scroll down for the official joint press release. Toyota and Mazda Team Up to Make Cars Better Tokyo, Japan, May 13, 2015-Toyota Motor Corporation and Mazda Motor Corporation today entered an agreement to build a mutually beneficial long term partnership. By leveraging the resources of both companies to complement and enhance each other's products and technologies, the partnership will result in more appealing cars that meet the diverse needs and tastes of customers all over the world. A joint committee will now be set up to evaluate how best to utilize each company's respective strengths. The committee will encourage broad and meaningful collaboration across a range of fields, including environmental and advanced safety technologies. Marking the agreement, Toyota President Akio Toyoda said: "As evidenced by their SKYACTIV Technologies and KODO-Soul of Motion design, Mazda has proven that it always thinks of what is coming next for vehicles and technology, while still managing to stay true to its basic carmaking roots. In this way, Mazda very much practices what Toyota holds dear: making ever-better cars. I am delighted that our two companies can share the same vision and work together to make cars better.

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.

Mazda6 diesel delayed until April

Diesel enthusiasts waiting on the new Skyactiv-D-powered Mazda6 will have to wait a bit longer. The shapely fuel-efficient four-door has just had its North American launch pushed back to April, due to delays in emissions testing. Mazda had originally planned to launch the Mazda6 diesel before the end of this year, making the four- to five-month delay a rather serious one.
Mazda's senior vice president of US operations, Robert Davis, told Mazda employees in a letter obtained by Automotive News that, "final certification testing - the results of which are looking encouraging - is taking longer than we had initially expected." Following this letter, Mazda made an official announcement:
"The on-sale date for Mazda6 SKYACTIV-D clean-diesel has been moved to late-Spring 2014, to accommodate final emissions testing and certification. We are pleased with the ongoing development and are excited to launch this much-anticipated vehicle in North America. 2014 Mazda6 sales continue to exceed both our expectations and our production abilities, and supplies of the car are short at dealers across the U.S. More information on the SKYACTIV-D clean diesel Mazda6 will be available closer to the on-sale date."
