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's new TNGA platform could boost Prius to 58 mpg

First, let's put the necessary context around the phrase, "Toyota New Global Architecture platform." The platform is important, but it is just one flowering bud sprouting from the real action, which is the production processes that will create it. It is crucial to understand that TNGA is fundamentally about a revolution in how Toyota designs and builds its cars - it even includes an overhaul of management and human resources - with one of the benefits being the new platform that the 2016 Prius will ride on. The Daily Kanban goes in depth about the changes, but integrated development for powertrain and platforms serves to reduces costs through more parts-sharing at the same time as it creates more cohesive platforms that are lighter, more compact, and have more efficient layouts. Regarding hybrids, Toyota says the new drive unit layout along with small components could raise hybrid efficiency "by more than 15 percent." That might enable the 2016 Prius to return 57.5-mpg combined - almost 59 in the city, 55 on the highway. Plus, the higher rigidity, lower center of gravity, and better suspension of the new platform will provide a better driving experience. All of these changes will be reflected in platforms for large and rear-wheel-drive vehicles, too. It is factory and build-process refinement that allows the development advances to be fully exploited. Toyota is making its lines more flexible, partly by having actual assembly lines that can easily be shortened, lengthened, or trucked somewhere else, and partly by introducing machines that can build parts for many different vehicles on the same line as needed, without using molds. The flexibility extends to capital investment, too, with much less money needed in order to switch to a new product build. Toyota says it is doing this to "improve core vehicle performance and product appeal," the overhaul making it simpler to produce new designs and features. Factory workers benefit from the flexibility as well; being able to build more types of cars means they aren't hamstrung by the sales fortunes of a small number of models.

LA Design Challenge invokes biology for 2025 concepts [w/poll]

Participants in the annual LA Design Challenge always manage to come up with edgy, wacky designs for future vehicles, but with a theme of "Biomimicry and Mobility: 2025" this year's crop of cars might be the quirkiest we've ever seen. As usual, automotive designers from around the world participated in this year's competition, and all the designs will all be unveiled next week during the LA Auto Show with a winner being announced on November 21.
Chinese automakers made a strong showing with Qoros, SAIC Motor, JAC Motors (the company responsible for the Ford F-150 clone) and Changfeng all bringing interesting takes on the biology, human intelligence and sustainability theme. One of the more innovative ideas among these automakers is the Qoros Silk Road System allows autonomous vehicles to drive in packs similar to how ants travel. Speaking of ants, the SAIC Motor Mobiliant (shown above) gets its design from the shape of an ant's body, and, like the insect, it can climb building acting as a personal elevator as well. The JAC Motors design also merges vehicle and building design, while the Changfeng LaBrea inspired by the design of muscle fibers.
Other entrants include Subaru and US-based design teams for BMW, Toyota and Mazda. BMW's duo of concepts mimic plant and animal life. The LA Subways concept acts as a submersible, single-person vehicle to take advantage of the LA river, with a shape similar to an Ocean Sunfish. The Sustainable Efficient Exploratory Device (SEED) imitates the shape of a seed pod, and uses propulsion methods inspired by a shark, dragonfly and a water bug. Mazda's Auto Adapt might be the most car-like concept of the bunch, while the Subaru Suba-Roo and the Calty-designed, Toyota e-grus are the most mind-blowingly awesome.
