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

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Mazda returning to top-tier racing with diesel-powered prototype in USCC

Mazda has unveiled its latest challenger in the top flight of endurance racing, a diesel-powered prototype that will campaign the inaugural, 2014 Tudor United SportsCar Championship. The new Skyactiv-D-powered car will make its race debut at January's Rolex 24 at Daytona.
"This is the most significant step Mazda has taken towards returning to the global racing stage since our overall victory at Le Mans in 1991," said the director of Mazda Motorsports, John Doonan. That historic racecar, the rotary-powered 787B, has grown to become one of Mazda's many, well-known racers.
More recently, the Japanese brand has been making waves in the Grand-Am series, campaigning RX-8s and, most recently, running diesel-powered Mazda6 sedans in the GX-class. Mazda will campaign two factory-backed prototypes at Daytona. Driver lineups will be announced closer to race day.
