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 JPN Taxi Concept is a Japanese riff on an English classic

As far as beasts of burden go, New York City's new - and much maligned - Nissan NV200 "Taxi of Tomorrow" isn't a bad one. It's space efficient, reasonably economical, and its simple construction should mean it's pretty robust over the long haul, too. But it lacks panache and a sense of occasion - let alone a sense of humor - three things this this Toyota JPN Taxi Concept we found at the Tokyo Motor Show has in spades.
Unfortunately, that's about all the information we have on this cheeky London-taxi-inspired showcar. Toyota hasn't provided much in the way of details, other than to proclaim that the five-seat JPN was "created with Japanese hospitality in mind" and it "aims to enliven city streets." Japan's livery landscape has long been occupied by traditional three-box sedans - models like the Toyota Crown and Nissan Cedric. The JPN Taxi at just over 171 inches would appear to offer both a tighter footprint and added whimsy, both of which are in the automaker's favor; we hear it hopes this concept will one day become the country's own version of America's yellow Crown Vic cab.
Toyota isn't providing powertrain specifications, but we like the airy feeling of the interior (Japanese cabs typically don't have cumbersome partitions between cabbie and passengers), the minimalist driver area with three screens, and the widescreen overhead video system for passengers that bookends the panoramic moonroof.

Scion reveals iM concept ahead of LA debut

After dropping a teaser image on us a few weeks ago, Scion has revealed in full the new iM Concept it's bringing to the Los Angeles Auto Show next week. As expected, the concept is clearly a rebadged version of the Euro-market Toyota Auris, only with some "European Racing Circuit Styling" upgrades to make it look more aggressive.
Along with the Scion logos, the five-door hatch is treated to a deeper air dam flanked by angular vents with stacked fog lamps, beefed-up wheel arches linked by widened side sills and filled with 19-inch, anthracite-finish alloys on low-profile rubber. Vented brake discs and four-piston calipers join an adjustable suspension as show-worthy equipment upgrades.
The sporty treatment continues around back with a similarly aggressive rear bumper and roof spoiler. Even the wing mirrors are replaced with narrower units. Little wonder it's all done up in a shade Scion calls "incrediblue" that looks rather similar to what sister-brand Lexus would put on one of its F-branded performance models - or for that matter what corporate ally Subaru would put on an STI hot hatches like the WRX.
