Junkyard Gem: 1990 Mazda 929 S

In the late 1980s, Toyota, Nissan, and Honda were cleaning up in the American market with the Cressida, Maxima, and Legend, respectively. Mazda wanted some of those dollars, so the HC-series Mazda Luce was modified for the US market and sold here as the 929. It had rear-wheel drive, a powerful V6 engine, and lots of luxury features, but not many were sold. Here's a rare '90 that I spotted in a San Francisco Bay Area self-service yard. In 1990, the sporty 929S version got 190 horsepower from its DOHC 3.0-liter V6. Unfortunately for Mazda, American buyers associated the marque with sensible econoboxes and screaming rotary engines, not luxury machinery, at the time. For the 1990 model year, American-market cars were required to have either a driver's-side airbag or automatic seat belts. The 929 had the automatic belts, the less said about the better. The Luce-based 929 became the Sentia-based 929 for the 1992 model year. Meanwhile, the new luxury brands from Honda, Nissan, and Toyota were kicking the crap out of 929 sales; Mazda had planned to launch the Amati brand in the United States, but didn't have the resources to follow through. The last 929s were sold in the United States for the 1995 model year. Related Video: Featured Gallery Junked 1990 Mazda 929 S View 16 Photos Auto News Mazda

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.

Toyota, Mazda partner to build EVs at new $1.6 billion U.S. plant

TOKYO — Toyota and Mazda plan to build a $1.6 billion U.S. assembly plant, the two said on Friday, as part of an alliance that will also see the Japanese automakers jointly develop electric vehicle technologies. The two will take small stakes in each other as part of the tie-up: Toyota, the world's second-largest automaker by vehicle sales last year, will take a 5 percent share of Mazda, extending its dominance in Japan's auto sector. Mazda will take a 0.25 percent share of its larger rival. The plant, something of a surprise at a time of overcapacity in the U.S. market, will be a boost to U.S. President Donald Trump, who campaigned on promises to increase manufacturing and expand employment for American autoworkers. The plant will be capable of producing 300,000 vehicles a year, with production divided between the two automakers, and employ about 4,000 people. It will start operating in 2021. The electric vehicles cooperation, meanwhile, comes as the tightening of global emissions regulations prompts more automakers to develop battery powered cars, as the industry struggles with hefty research costs and intense competition from technology companies over technology like self-driving cars. As part of the agreement, Toyota and Mazda will also work together to develop in-car information technologies and automated driving functions. Toyota, Japan's biggest auto company, has been forging alliances with smaller Japanese rivals for several years, effectively engineering a loose consolidation of the Japanese auto sector. It already owns a 16.5 percent stake in Subaru, Japan's No. 6 automaker, with which it also has a development partnership. Toyota is also courting compact car maker Suzuki to cooperate on R&D and parts supply as Toyota seeks to tap its smaller rival's expertise in emerging Asian markets. A stake in Mazda may also prevent future incursions by tech companies, one analyst said. "For a technology company which lacks the expertise in making cars, Mazda could look like a very interesting acquisition. They're very good, they're not too expensive. Maybe Toyota realizes this," CLSA managing director Chris Richter said. "By buying a 5 percent stake, Toyota takes Mazda off the table rather than having it sit out there like a free agent which could someday be used against them." COROLLA PRODUCTION SHIFT Mazda stands to gain from a deal that gives the small automaker a production foothold in the United States.
