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.

Fewest vehicles ever found eligible for Most American survey

Once again, the most American car on the market is from an American brand. The Ford F-150 retained its number one spot in Cars.com's annual survey of the most American vehicles, trumping the Toyota Camry, which remains at number two.
Ford taking the top spot is small consolation, though, as the Detroit Three aren't too well represented here. General Motors scored a win at number seven, with the Chevrolet Corvette, while Chrysler squeaked in at number ten, with the Dodge Viper. Outside of those three vehicles, Toyota and Honda dominate the top ten.
What's most remarkable, though, is that there were so few cars available for this year's list.

Toyota will race C-HR CUV in 2016 Nurburgring 24 Hours

There won't just be traditional racecars competing in the 2016 Nurburgring 24 Hours; Toyota Gazoo Racing will take the bizarre route of prepping the C-HR crossover for the grueling event. The squad will enter more conventional machines, too, including a Lexus RC and RC F for the race that will run from May 26-29. Details about the C-HR Racing are scant at the moment. "We decided to take on the new challenge of creating ever-better cars using a crossover rather than a pure sports car," the company's announcement said. It makes no mention of the vehicle's specs, but the included photo show the CUV with a more aggressive front fascia, vents along the hood, and a big wing at the rear. The driver lineup includes Masahiko Kageyama, Kumi Sato, and another person to be announced later. Toyota will reportedly introduce the production version of the C-HR at the Geneva Motor Show, and the final one will allegedly carry over the current rakish shape and hybrid powertrain. The company also showed it with Scion badging at the 2015 LA Auto Show to suggest a likely arrival in the US. This year will mark a decade of Gazoo Racing's competition in the 24 Hours of the 'Ring. The squad notably raced the LFA there for several years, but it showed a willingness to bring weirder vehicles too like a Lexus CT 200h in 2011. Nothing has been quite as odd as racing a crossover there, though. Toyota GAZOO Racing Celebrates Decade of Participation in the 24 Hours of Nurburgring with Triple Entry for 2016 Race Toyota City, Japan, January 15, 2016-Toyota GAZOO Racing announces the entry of three vehicles-a Toyota C-HR Racing*, a Lexus RC, and a Lexus RC F-in the 44th 24 Hours of Nurburgring endurance race to be held in Germany from May 26 to 29, 2016. The 24 Hours of Nurburgring plays an important role in Toyota's motorsports activities for building ever-better human resources and vehicles under intense racing conditions. Beginning in 2007, the 2016 event marks the 10th year of Toyota's participation in the race under the banner of GAZOO racing. When asked to look back over the last ten years, team representative Akio Toyoda said, "I remember GAZOO Racing first taking on the challenge of the Nurburgring in 2007 in an Altezza like it was yesterday. There are so many memories running through my mind–the interaction with the roads of the Nurburgring, whose characteristics seem to change with each shift in the weather, the meeting and parting with new and valuable friends.
