Honda, Nissan and Mazda recalling 3 million vehicles for airbag inflators

Three million more vehicles can be added to the worldwide tally to be repaired for the faulty airbag inflators supplied by Takata. Honda, Nissan, and Mazda have all issued recalls to replace the bad part, including about 1.2 million of them in North America. NHTSA has been investigating all three companies, plus Chrysler and Toyota, for potentially affected vehicles.
Honda is recalling roughly 1.02 million Civic, CR-V, Odyssey and Element models In North America, built between April 2000 and October 2002. Mazda needs to repair 14,794 units of the RX-8 and Mazda6, and Nissan has 228,000 vehicles in North America to be fixed.
Chrysler is also starting what it calls a "regional field action" to replace the inflators in the 2006 Dodge Charger, according to a company spokesperson. The company says that it has not yet found the problem in any of its vehicles, but it's being done "out of an abundance of caution." The final number of Chargers affected will be announced later this week.

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.

Toyota confirms C-HR crossover to debut at Geneva

With the compact crossover segment booming with new entries, Toyota soon intends to burst into the popular market with a production version of the C-HR concept. The rakishly styled, little CUV will show off its final face at the 2016 Geneva Motor Show next March, and European sales will start before summer, Autocar reports. Customers in the US will likely get to drive the angular model, too. The C-HR concept's chiseled shape is expected to make the transition to the road largely unaltered. According to Autocar, customers reportedly really dig the razor-sharp look versus a more conventional CUV design. A hybrid is also expected to be included in the production powertrain lineup, but non-electrified options could be available, too. The Japanese automaker last displayed the C-HR at this year's Frankfurt Motor Show. Underneath the avant-garde shape, the Toyota New Global Architecture provided the underpinnings, and a hybrid powertrain was there for propulsion. The concept's general design idea was actually the revival of a three-door crossover from the 2014 Paris Motor Show. In addition, the production C-HR is expected eventually to arrive in the US but likely wearing a Scion badge. Spy shots highly suggest that a crossover is already under development, and the entry would give the division a much-needed challenger to the Nissan Juke, Honda HR-V, Mazda CX-3, and plenty of others. Plus, the brand is keeping it absolutely no secret that a third, new model is on way to join the iA and iM.
