California adapts ZEV mandate with PHEVs for smaller automakers

California is the nation's largest market for zero-emissions vehicles with over 100,000 of them estimated to be on the roads there. The state's goal is to keep that number growing every year. To that end, the California Air Resources Board is now tweaking its rules in a way that might not boost ZEVs but could mean more plug-in hybrids for the Golden State. Jaguar Land Rover, Mazda, Mitsubishi, Subaru, and Volvo asked for an exemption to the state's zero-emissions vehicle mandate last year due to their relatively small development budgets compared to larger automakers. CARB denied their request but did craft a compromise, according to Automotive News. Rather than being required to offer a ZEV in the state, companies with an annual global revenue of less than $40 billion, like those in this group, may instead sell plug-in hybrids to earn ZEV credits. The companies aren't completely off the hook, though. If these plug-in hybrids don't earn enough credits, the corporations must buy them on the market to make up the difference. Automakers with popular electric models like Nissan and Tesla have made a big business through this trading system by selling their surplus to rivals. Tesla alone pocketed $51 million in the first quarter from this part of its business, according to Automotive News. The changes to the regulations also aren't set in stone, yet. CARB is meeting in 2016 and could adjust things further at that time.

Mazda still has a team working on rotary engines

The flame still burns within Mazda to stage a rotary engine revival. Before you start getting excited, it's way too soon to start saving money for the fabled, next-gen RX-7 or RX-8. Still, company boss Masamichi Kogai confirmed to Autocar that the Japanese automaker has an engineering team dedicated to improving the Wankel. This development group has the hard task of trying to make the rotary stack up to modern internal combustion engines in terms of emissions and fuel-economy standards. Neither factor were ever exactly Wankel's strong suits. Kogai described them as working "very enthusiastically" to Autocar. The boss didn't discuss any future RX-vehicles or the size of the team, however, a report from last year indicated that there were 30 engineers in partnership with universities to update the engine's design. After problems keeping up with emissions and fuel economy, Mazda built it's last rotary for an RX-8 in June 2012. Since then, there have been intermittent rumors of a return. One possible solution was a design called the 16X that was supposed to offer more torque and better fuel economy. Another possibility was a small-displacement unit as a range-extender in an electric Mazda2. Rumors of a new RX-7 have been heard for years. In 2013, Kogai clearly said that it wasn't happening. When asked again last year, he reiterated the same point.

2014 Mazda Skyactiv Prototype looks ready for Daytona

With less than two weeks before the Mazda Skyactiv Prototype makes its race debut at the 2014 Rolex 24 at Daytona, the Japanese Zoom-Zoom brand brought its diesel-powered racer to the floor of the 2014 Detroit Auto Show.
The red prototype marks Mazda's return to prototype racing, and will campaign the inaugural Tudor United SportsCar Championship using a 2.2-liter, SkyActiv-D diesel engine. With 451 horsepower on tap and 580 pound-feet of torque, the racer should stand up well against a field of gas-powered competitors.
Should the Skyactiv win Daytona, it'll be a coup for Mazda. The racer is running an engine with over 50 percent of its parts drawn from the oft-delayed production Skyactiv-D. Head up top for our full gallery of images of the new Skyactiv Prototype. The 2014 Rolex 24 will be run from January 25 to 26.
