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 won't build new Mazdaspeed3 or 6 based on current models

It's sad news but not entirely unexpected: According to a Motoring interview, Mazda doesn't intend to build high-performance versions of the latest Mazda3 and Mazda6. Instead, it will wait for the next generations of those cars to arrive before applying the Mazdaspeed treatment. When the future performance models do eventually arrive, expect them to take a step upmarket compared to the last ones. In the meantime, the Japanese brand will focus its engineering resources on the next-generation Skyactiv engine family, according to Mazda's North American operations president and CEO Masahiro Moro. "Our research and development department is 100 percent focused on delivering Skyactiv generation two and if we don't have this we don't have any other derivatives," Moro told Motoring. Once the new engines arrive around 2017, Mazda's engineers can start to develop performance versions. "MPS or performance model or a sort of iconic model of the future will be a little bit later at this stage," Moro said. Moro is already thinking about the direction for the future performance vehicles. He calls the previous Mazdaspeed3 "childish" and thinks it's time to go a different way. "Mazda brand has become more mature, more upscale, more sophisticated, and we have a new transition of the brand to relate that direction," he said. Rumors last year suggested that Mazda might introduce a new Mazdaspeed3 (speculative rendering above) as a concept at the 2015 Frankfurt Motor Show. It would have reportedly used the CX-9's 2.5-liter turbocharged four-cylinder tuned to 295 horsepower and an all-wheel-drive powertrain. The vehicle never appeared, though. The current Mazda3 and Mazda6 arrived in 2014, so a new generation of each wouldn't arrive until around 2020. That would put Mazdaspeed derivatives at 2021 or later. In short, it will be a while. For customers that have the Driving Matters attitude now, Mazda still offers the award-winning MX-5 Miata as a convertible and soon with an impressive folding hardtop. Plus, Fiat will sell its own versions of the car with 160 hp. We wouldn't mind if Mazda turned up the heat a little by introducing something like the Racing concept from last year's Tokyo Auto Salon, though. Related Video:

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.
