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.

Buy a Toyota GT86 and your wife will hate you

Marketing can be a very strange business. Convincing a man or woman (or child, really) that they absolutely cannot live without the latest, greatest new bit of technology oftentimes takes a unique approach. In the "online film promoting the Toyota GT86" you'll see below, created by agency Happiness Brussels, men are reverse-psychologied into thinking a new sports coupe will make them more masculine by getting their loved ones to hate them. Or something like that. We think.
In any case, we suggest you watch the video below to see how much fun men can have with a GT86 - or Scion FR-S or Subaru BRZ, presumably - at the expense of their significant others. Fair warning: There's a potential Not Safe For Work moment in the ad: beware of a brief male butt shot about 44 seconds in.
Marketing. Gotta love it. Unless you're married to a man. Or something like that. We think. Whatever, just watch.

This first-gen Toyota Celica is one mean mother

Brian Karasawa's gen-one Toyota Celica is, in a word, badass. As a long-standing fan of the marque, the doting owner has tried to both restore and improve his Celica keeping period-correct modifications in mind. The 20R/22R mashup engine is outputting roughly 185 horsepower and graced with a lot of JDM-specific parts and modifications. Clearly, the exhaust has been upgraded from stock, as clips of the orange Toyota in motion are accompanied by one hell of a nice sound.
Tastes clearly vary, and there's not as much love for the first-wave of Japanese metal as there is for similar era American-iron, but we're pleased to see these cars finally getting more time in the spotlight. Scroll down below to see why we're stoked, and consider cruising your local Craigslist for late 1970s and early 1980s Japanese coolness (before we get there first).
