CARB uses tricked-out RAV4 EV to measure air pollution in California

The old-school Toyota RAV4 EV you see above is the California Air Resources Board's version of a non-participant observer. The all-electric vehicle cruises around the state measuring airborne pollution. Since it's powered by batteries, there are no tailpipe emissions created as CARB tries to get a handle on how dirty the roadway air is. The problem, CARB says, is that it is difficult to measure air pollution levels, "during calm conditions at night and in the early morning." There are over 250 stationary air monitoring sites in California today, but the Board wanted a way to expand where and when it can test for things like ultrafine particles, carbon dioxide and nox. The original plan for the Mobile Monitoring Platform – as the RAV4 EV is officially called – was to "Investigate Spatial, Diurnal and Seasonal Pollution Gradients" on California's highways and ports. The RAV4 EV was originally expected to cost $280,000 (see pages 11-12 in this PDF from 2009), but a new report in the Modesto Bee says it had a total of $300,000 just in monitoring equipment. Michael Benjamin, CARB's chief of air monitoring, told the Bee that the MMP, "paints a thorough picture about what air quality is in any given community." More importantly, the stationary and mobile testing equipment can tell CARB when and where the air is getting cleaner. Which is the whole point, after all.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.

No diesels in the running for 2016 Green Car Of The Year

It's a new era for the Green Car Of The Year. In the past, the theme of the award was to take a broad look at alternative powertrains and pick the best among them. "Clean diesels" from the Volkswagen group were often among the finalists and won the award twice. For the 2016 edition - which will be handed out at the LA Auto Show next month - not a single diesel made the list. There's little wonder why. Green Car Journal, which names the winner with a panel of experts, had to strip two VW brand vehicles of their past wins. The 2009 VW Jetta TDI, which won in 2008, and the 2010 Audi A3 TDI, which won in 2010, have both lost their titles now that the world knows about the "defeat devices" that VW installed in many of its TDI vehicles around the world. So, what does that leave us with for 2016? Two plug ins, a hybrid, and two gas vehicles. The two electric vehicle are the Audi A3 e-tron and the Chevy Volt, while the all-new Toyota Prius (which will come with a plug-in version later) is the lone pure hybrid. Rounding out the pack are two efficient gas models: the Hyundai Sonata and the Honda Civic. This is the tenth year for the Green Car Of The Year, and it will be interesting to see if diesels can come back into the award's good graces (for the record, no diesels were among the finalists in 2013, either) in the future. For now, we'd like to know who you think should win. You can read more about the finalists in the press release below and then cast your vote in our poll.
