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 finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

Recharge Wrap-up: Audi to build Q6 e-tron in Brussels, Boris Johnson test drives Toyota Mirai

Audi will build the Q6 e-tron at its factory in Brussels, Belgium. Production for the electric vehicle - which will be based on the concept car from the Frankfurt Motor Show in September - is slated for 2018. Its expected driving range of about 311 miles should help make it competitive against the Tesla Model X. Audi's Brussels plant is also where the A1 is made. It employs about 2,500 workers and produced about 115,000 vehicles in 2014. Read more from Automotive News Europe. During a visit to Toyota Headquarters, London Mayor Boris Johnson confirmed that Transport for London will be the UK's first Toyota Mirai customer. Mayor Johnson traveled to Japan on a three-day trade mission, and took a test drive of the fuel cell vehicle. "By embracing this technology of the future, we aim to consolidate hydrogen's role as a practical alternative fuel for the 21st century and beyond," says Johnson. "I am sure that Transport for London will provide the ideal environment for us to see everything Mirai can do and, in doing so, take another great step towards improving air quality in our city and protecting the health of Londoners."

The South Coast Air Quality Management District (SCAQMD) has delivered 12 electric commercial lawn mowers to government and nonprofit organizations in San Bernardino County. The donation of the electric mowers is part of a demonstration program to promote zero-emissions equipment. At prices ranging from $3,000 to $20,000, the electric mowers cost about 25 percent more than their gas-powered counterparts, but their lower operating costs can make up for the price difference in about two years. In addition, they produce about half the noise, and save about 600 pounds of harmful emissions per year. SCAQMD plans to deliver five more of the mowers as part of the same program.
