Toyota reveals Tokyo Motor Show concepts

Toyota is getting ready for the Tokyo Motor Show later this month, and to tease us, the Japanese automaker has released photos and information about the concept vehicles it'll be bringing to the show. In all, there'll be five world premieres from Toyota (six if you split the Voxy and Noah minivan concepts), including some vehicles that'll be released in the near future, and others that need more time to incubate.
Let's get the world premieres out first. Toyota is a pioneer of gasoline-electric hybrids, but it's also pursuing hydrogen fuel cell-powered vehicles. The clearest indication of this is the FCV concept, a hydrogen-powered sedan in the same vein as the the FCV-R that will bow at the auto show. (Read more about the FCV, here.)
Other world debuts include the FV2 concept (pictured), a unique, one-seat future vehicle that emphasizes the "Fun to Drive" philosophy; the JPN TAXI concept, a next-generation taxi concept designed with Japanese hospitality in mind; and the Voxy and Noah concepts, next-generation minivans that differ most in exterior design cues and are scheduled to launch in the Japanese market in early 2014.

Toyota announces two recalls affecting 1M Corolla, Matrix and Lexus IS models

The recall bug strikes Toyota again. The automaker has issued a voluntary recall of three models that, in total, represent more than one million units. Around 752,000 2003-2004 Toyota Corolla and Matrix models are being recalled for airbag concerns, while a windshield wiper issue is causing the recall for close to 270,000 Lexus IS sedans from the 2006-2012 model years.
Completely unrelated to the small airbag-related recall issued earlier in the week, the Corolla and Matrix recall is caused by a faulty airbag control module that could potentially short circuit, which could lead to the front airbags or seat belt pretensioners deploying. The Lexus recall is due to a wiper arm nut that wasn't tightened properly, which can cause the wipers to not work when trying to clear heavy buildup such as snow.

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. Read more in the press release below. 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.
