Toyota and Lexus recalling 235,000 hybrid CUVs and sedans over separate issues

When it rains, it pours. Toyota has announced a pair of separate but voluntary North America recalls covering approximately 235,000 vehicles built between 2006 and 2011. The larger of the two recalls targets Toyota's hybridized crossovers, the Lexus RX400h and Toyota Highlander Hybrid. 133,000 units, including 2006-2010 Highlander and 2006-2008 RX crossovers are covered in the campaign. The other recall affects 102,000 IS350 sedans, IS350C convertibles and GS350 sedans built between 2006 and 2011.
With the CUVs, the faults in the parallel circuits of the transistors can cause heat damage in the inverter assembly, triggering an abundance of warning lamps and sending the vehicle into limp mode. The Lexus sedans are being recalled due to loose bolts on the variable valve timing controller. Detected by unusual underhood sounds on startup, the issue can cause the engine to stop while driving. The inverter issue is also triggering similar recalls in Japan and Europe.
At the moment, it's unclear if any of these issues have caused any crashes or injuries. Toyota says it plans to notify owners of the recall via snail mail. Additional information for owners can be found on the recall sites for Toyota and Lexus or by calling Toyota's customer service line, at 1-800-331-4331.

Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.

Ex-Toyota Bill Reinert still in favor of hybrids, against EVs

Former Toyota executive Bill Reinert is so unsold on electric vehicles as a viable advanced-powertrain option for future transportation that he has praised – gasp – Ford, for its downsized internal combustion engines. Reinert was a key player in developing Toyota's original Prius hybrid and, in an interview published in Yale University's Environment 360 blog, said a hybrid that gets 60 miles per gallon is superior to an electric vehicle. "And that is why you will be seeing more fuel cells in the future." – Bill Reinert Reinert went on to praise the advances that automakers have made in improving fuel economy of fossil fuel vehicles, specifically namechecking Ford and its three-cylinder Ecoboost engine. He also has good things to say about both hydrogen fuel-cell electric technology as well as natural gas vehicles, but admits that limited fueling infrastructure will keep those types of vehicles in the margins for the near future. He also says that hydrogen vehicles aren't that great yet but that, "When most [manufacturers] investigate the two technologies [H2 and EVs], they see that FVCs offer more room for performance improvement and cost reduction potential. And that is why you will be seeing more fuel cells in the future." As far as pure electric, Reinert says lithium-ion batteries have "tremendous shortcomings" and talks about battery degradation, substandard performance in hot weather and, of course, limited single-charge driving range. He also says that people need to factor in the environmental impact of producing electricity for the grid to fully gauge how environmentally beneficial EVs can be. We'd like to take him and Tesla Motors Chief Elon Musk to what we think would be a spirited lunch. You can read the whole interview with Reinert here.
