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.

Andrew Gilleland is new VP of Scion, Murtha moves to Toyota

Scion is getting some fresh blood at the top as Andrew Gilleland (pictured above) becomes the new vice president to take over for Doug Murtha. Gilleland is no stranger to the division, and served as the national field operations manager early in the brand's launch. Murtha moves to take leadership of corporate strategy and planning for Toyota in North America. "Now it's Andrew's charge to spread the message of the style and value of the iM and iA, as well as a third new vehicle that will be added to the lineup," Toyota division group vice president Bill Fay said in the announcement. Gilleland moves up from being general manager of Toyota's central Atlantic regional office. He takes the reins at Scion at a potential turning point for the division. Sales volume for the year through August is down 22.1 percent to 32,691 vehicles, but some big changes are afoot. The long-lived xB is likely about to bow out, and the brand is launching two new products with the iM and iA. They're getting some celebrity advertising, too. Spy shots also suggest the FR-S might get a refresh soon. Plus, the third model Fay teases is expected to be a compact crossover, possibly with styling inspiration from the Toyota C-HR concept. Scion could get a big boost by having an entry in that booming segment. New Products, Previous Player - Scion Introduces New Vice President Andrew Gilleland Returns to Youth Brand September 24, 2015 TORRANCE, Calif. (Sept. 24, 2015) – In the early days of Scion, when xAs and xBs were flying out of dealers' showrooms, Andrew Gilleland was the National Field Operations Manager for the youth brand. He was responsible for working with dealers to ensure they embraced the new products and processes Scion offered. Now, Scion is entering its teen years, and Gilleland is back as Vice President of Scion, once again encouraging dealers to sell its new models and investigate new methods to attract young buyers. "Scion has sold nearly a million vehicles since I left in 2005 and I'm excited to be back leading this team," said Gilleland. "The iM 5-door hatchback and iA sports sedan arrived at dealerships earlier this month and the response has been great.

2020 Honda CR-V Hybrid vs other hybrid crossovers | How they compare on paper

The long-anticipated 2020 Honda CR-V Hybrid was announced yesterday, and although we don't have every spec available (including the all-important official fuel economy figures), Honda provided enough that we can piece together a comparison of powertrain specs and dimensions. The same can be said of the 2020 Ford Escape Hybrid, which we just drove for the first time.  Together, they represent a significant increase in the number of compact crossover hybrids, as the current total is one: the 2019 Toyota RAV4 Hybrid. The old Nissan Rogue Hybrid has been discontinued, leaving the subcompact Kia Niro Hybrid as the only other vehicle in the ballpark. As you'll see below, its size and performance are much different than the others, but its fuel economy and price are superior.  Performance The RAV4 Hybrid is the performance champ of the group, but both it and the new CR-V Hybrid are actually more powerful than their respective gas-only siblings. Although the added weight of its battery pack negates much of that horsepower advantage, the RAV4 Hybrid's subsequent acceleration is indeed a smidge quicker than the gas-only version. It will be interesting to see if that's the case with the CR-V. By contrast, the Ford Escape offers a 250-horsepower 2.0-liter turbo engine, meaning the hybrid variation is most definitely not the Escape's highest-performance offering. Nevertheless, the Hybrid does produce more power than the base 181-horsepower 1.5-liter three-cylinder. The Niro, meanwhile, brings up the rear in terms of performance, but Kia estimates a perfectly acceptable 0-60 time of 8.6 seconds. The others are likely in the mid-7-second range. Fuel economy This is ultimately an open question since we don't have official figures for the CR-V and Escape. Based on Honda's estimate of the CR-V Hybrid being 50% more efficient in the city than the gas-only version, our calculators say it should get 43 mpg in the city. Then, based on information provided on the Escape Hybrid first drive and some more calculation, our best guestimate for it is 40 mpg. Either way, given how mpg is calculated, any potential differences between them in terms of actual fuel burned should be negligible.  On the other hand, most Kia Niros sold get 51 mpg in the city and 49 mpg combined. According to the EPA, that translates to an annual average fuel cost of $750. The RAV4 Hybrid, by contrast, is $900.  FWD vs AWD Note that the CR-V and RAV4 come standard with all-wheel drive.
