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.

A closer look at the 2015 Subaru Legacy

The Subaru Legacy might not have been the hottest debut at the recent Chicago Auto Show, but for the Japanese automaker, it's hugely important. Much as we'd love to focus on Subaru's more engaging WRX, STI and BRZ models, the truth is, its the mainstream Forester, Outback and Legacy that make up the vast majority of the brand's sales, not to mention the Impreza and XV Crosstrek.
This new Legacy looks to gain a lot more traction in the mainstream market than its predecessor, with handsome, if familiar, styling, standard all-wheel drive, and more efficient powertrains. Under the hood, customers can choose between a 2.5-liter boxer-four, or a more powerful six-cylinder engine. Subaru says that the four-cylinder setup actually boasts class-leading fuel economy for all-wheel-drive vehicles in the Legacy's class.
West coast editor Michael Harley stopped by the Subaru stand for a closer look at the 2015 Legacy. Check it out in the video below.

Is Subaru close to ditching 6-cylinder engines?

Despite niche outliers like the 6.2-liter supercharged Hellcat V8 and 7.0-liter V8 in the Chevrolet Camaro Z/28, we live in an era where small-displacement, turbocharged engines are becoming the norm. In many model lineups, a boosted four-cylinder now holds the place that a six might have just a few short years ago. At least in some markets, Subaru could be the next automaker to follow this path by axing its 3.6-liter boxer six-cylinder. Granted, that's not as much of a leap for Subie as some other automakers because the Japanese brand is already closely associated with turbocharged four-cylinder engines. The company's six-pot boxer is currently only offered in the Legacy and Outback in the US. Australian website CarAdvice spoke with Subaru deputy general manager of engineering Yoichi Hori about the company's future powertrain plans at least for Down Under. "Our research said the six-cylinder model is decreasing in the world. So that's why probably the future, many companies take the smaller displacement with a turbocharger, or diesel, or hybrid," said Hori to CarAdvice. He was also specific about which engine he had in mind. "In terms of the body size, a 2.0-liter with a turbocharger is enough, I think," he said. Hori said that the automaker stuck with the boxer-six for so long because of the turbocharged four-cylinder's higher maintenance costs. Slotting Subaru's 2.0-liter turbocharged boxer four-cylinder into the Legacy and Outback seems easy to imagine. After all, the mill already does duty in different tunes in the Forester and WRX in the US. Keep in mind, though, that Hori's words are aimed at the Aussie market. A rumor from earlier this year speculated the company's midsize models might get a smaller displacement six and the turbo four for some trims.
