NHTSA investigating 561k Toyota Prius hybrids for possible steering shaft defect

The Detroit News is reporting that the National Highway Traffic Safety Administration will investigate some 561,000 Toyota Prius models for potentially defective steering shafts. The affected hybrid models are from the 2004-2009 model years. The story indicates that NHTSA is weighing whether or not to grant a defect petition, which claims that Toyota incorrectly assembled the hatchback's steering linkage.
As of this writing, there is no recall. However, a recall based on the Prius steering shaft would be the third related to steering issues for the model since 2006. Seven years ago, Toyota recalled 170K Prius models for potential cracking of the intermediate shafts, and in November of 2012, the automaker recalled 670K units to replace the steering shaft extension assembly.
We'll be monitoring NHTSA's signals to see if this investigation turns into a full-fledged recall. For now, stay tuned.

Toyota Camry to go turbo

As automakers strive to meet regulations, turbocharging is rapidly becoming the norm whether looking at pickups, sports cars or family sedans. However, Toyota remains a stalwart to the changing tide, and for the time being a trip into one of the brand's dealers shows nary a hint of forced induction – probably not for long, though. With models like the Lexus NX 200t and forthcoming IS 200t pointing the way, a big shift is afoot for one of the Japanese automaker's most popular products. Obviously, Toyota is no stranger to forced induction for performance applications like the turbocharged models of the Supra and MR2 in the '90s. But rather than reducing lap times, the latest application is more about improving emissions and fuel economy. According to Automotive News, the Camry is getting a 2.0-liter turbo four-cylinder in the near future as a replacement for its V6 engine option. The 3.5-liter six currently in the venerable sedan already makes 268 horsepower and 248 pound-feet of torque, versus 235 hp and 258 lb-ft in the NX 200t or 241 hp and 258 lb-ft in the IS from the new four. The base four-cylinder also might receive some upgrades. It could grow larger and run on the Atkinson cycle to find improvements, according to Automotive News. There might be a move towards CVTs, as well. Toyota is hardly alone in the shift towards forced induction. Honda is known to have a 1.5-liter turbo mill on the way for the next-gen Civic. In addition, that engine might find its way into the Accord and CR-V as well, according to Automotive News. Among the major Japanese automakers, only Nissan is taking a more measured approach towards forced induction in mainstream models. Rather than going all-in on turbos, the company is expected to shift more of its engines to direct injection to go after fuel economy gains.

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.
