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.

KBB 2013 Brand Image Awards has some obvious and oddball winners

The sixth edition of the Kelley Blue Book Brand Image Awards have crowned a wide range of winners - in a couple of cases the recipient of the laurels might say more about KBB users than they do about the actual winner. Compiled from the responses of more than 12,000 shoppers on KBB.com over the past year, there are 13 categories broken into non-luxury, luxury and truck segments "representing the combined wisdom of the American car-buying public."
The award categories have been revamped this year, with some dropping off, some new ones appearing and at least one other given a new term. What isn't surprising is that Honda won Most Trusted Brand for the second year running, Best Value Brand for the third year in a row and took Best Overall Brand, which wasn't on last year's list of awards.
On our own shores, in the non-luxury categories Chrysler got Most Refined Brand and Buick took Best Value Luxury Brand. Neither one of those marques won anything in last year's Brand Image Awards, while Cadillac, which won Best Interior Design Brand and Best Comfort Brand last year - those awards disappeared this year - went home without a single accolade.

2015 Toyota Camry set to circle NASCAR track near you

Toyota recently introduced the all-new 2015 Camry for the street, so it follows that it should want to promote its new bread-and-butter sedan by putting it out on the racetrack as well. And that's just what it's done here with the release of the new Toyota Camry for the NASCAR Sprint Cup Series.
The new Camry represents the first reskin of the standard stock car chassis since the Gen-6 model was introduced in 2012. Toyota's Calty Design studio worked closely with series organizers to determine which parts could be redesigned to more closely resemble the new production model, and what you see here is the result. Since it is based on the same control chassis as all the others, the Camry's skin is applied over a steel tube frame and powered by an old-school 5.86-liter pushrod V8 mated to a four-speed manual gearbox.
Although the idea of a Japanese automaker in American stock car racing didn't initially get the warmest reception from some of the good ol' boys when it first entered the series back in 2007, it has by now become a staple of the NASCAR circuit. After all, it's hard for even the most patriotic of racing fans to argue with the US-built Camry's ranking as one of the most American cars by content on the market.
