Toyota's future fuel cell vehicle lineup revealed?

Being an Olympic sponsor from 2017 through 2024 puts Toyota in the international limelight, and the company is preparing a fleet of efficient, cutting-edge vehicles just in time for the Tokyo games in 2020. At least eight new models could be on the way, according to Automotive News citing Best Car from Japan. Three of those might make use of the hydrogen fuel-cell powertrain developed for the Mirai. While many of these fuel cells are going into Japan-only vehicles, one of them could come here. Reiterating earlier rumors, Automotive News reports a hydrogen-powered Lexus LS is set for 2018. It could be even lighter than the current hybrid model, too. A similar version of the Toyota Crown would launch there in 2019 and possibly an FCEV Estima minivan, too. Beyond fuel cells, Toyota also intends to put the JPN Taxi Concept from the 2013 Tokyo Motor Show into production in time for the games, according to Automotive News. For 2017, the brand's flagship Century is also expected to adopt a hybrid V8 to replace the current V12, as well. Plus, many of its Japanese-market vans are also due for updates. All of this is certainly a massive undertaking to be ready in time, but Tokyo want to use the games as a chance to show the city as an innovative, international destination. Automotive News predicts Toyota could supply thousands of vehicles to haul all of the athletes and dignitaries around. In addition, the Japanese government wants 6,000 fuel cell vehicles on the road and 35 refueling stations up an running for the games. Related Video:

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.
