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 Camry Dragster takes the phrase 'sleeper' to its logical extreme [w/video]

Sometimes, looks can be deceiving. This is certainly one of those times, as Toyota successfully trolled the entirety of the media corps at the 2014 SEMA Show by rolling an innocent-looking Camry onto the floor... only to lift literally the entirety of its body to reveal an 850-horsepower, tube-framed dragster. Well, we have been asking for a more driver-oriented Toyota.
While it's designed to go fast in a straight line, the origin of the Camry Dragster's parts might be surprising. The 5.7-liter V8 engine, transmission, rear axle and electronics were plucked from the Toyota Tundra pickup. Toyota Racing Development donated a supercharger, while a wet-nitrous-injection system was also tacked on for that little extra something. Those goodies will help propel this anonymous looking monster through the quarter mile in just 9.8 seconds.
"This is the most extreme build we've ever unveiled at SEMA," said Toyota's motorsports chief Steve Appelbaum said in a statement. "The transformation from seemingly stock Camry to full-blown racecar just shocks the senses. Chuck Wade and the team at Motorsports Technical Center did a truly spectacular job executing the vision of this project."

2016 Toyota Tacoma shows its face ahead of Detroit debut

Here's your first full look at the 2016 Toyota Tacoma ahead of its debut at next week's Detroit Auto Show. No details have been released just yet, but at first blush, the revised Taco looks to be a much-needed step forward for the Japanese midsize pickup. We like the chiseled, modern face of the new Tacoma – it's pretty clean, not to mention rugged and handsome. The body sides almost look carried over from the current pickup (they very well could be), and around back, there's a new tailgate with badging stamped into the sheetmetal, as well as some fresh new taillamps. We can't yet see inside the Tacoma's cabin, though we expect it to have been thoroughly refreshed, as well – that's the place where the current truck really shows its age. As we said, Toyota hasn't released any other details, but the badging on this truck shows a V6 engine lies underhood. A four-cylinder option makes sense, as well – especially if the Tacoma wants to adequately compete with the recently launched (and well-liked) Chevrolet Colorado and GMC Canyon twins. We'll know soon if this Tacoma is a fully baked, all-new model, or if its just a thorough refresh on an existing (and old) truck. Stay tuned.
