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.

Honda, Hyundai top car residual value / depreciation awards list

J.D. Power announced its 2022 U.S. ALG Residual Value awards Thursday, with Honda and Hyundai topping the charts at three models apiece in the industry-standard study. The term "residual" is an industry projection of how well a car will hold its resale value three years from the original purchase date – a key metric in calculating lease costs and projecting new-car depreciation.  Award winners included several enthusiast-friendly options, including the BMW 2 Series, Dodge Charger, Subaru WRX, Mercedes-AMG GT and Toyota Tacoma. Even the Ford Bronco was recognized, beating out the Jeep Wrangler in the Off-Road Utility segment. That may seem odd given the car's issue-plagued launch, but scarcity apparently trumps quality control issues over the longer term. Here's a scrolling complete list of winners broken down by segment: “Accurately forecasting residual values in the auto industry is a key factor in assessing an estimated $225 billion lease portfolio of vehicles in the United States,” said ALG VP Eric Lyman in the company's announcement. "The brands and vehicle models that rise to the top demonstrate that they score well across the award programÂ’s criteria, including manufacturersÂ’ superior design and quality." ALG looks at several factors to determine future value, which is especially tricky with new models. For 2022, 16 different brands were recognized across 29 segments. Behind Honda and Hyundai, Audi, Kia, Mercedes-Benz, Land Rover and Subaru all managed to chart with two different models. Here's the rundown of those who won in more than one category: Honda Civic Honda Passport Honda Odyssey Hyundai Accent Hyundai Kona Hyundai Kona EV Audi A6 Allroad Audi Q3 Kia K5 Kia Telluride Land Rover Range Rover Velar Land Rover Discovery Mercedes-AMG GT 4-Door Mercedes-Benz Metris:  Subaru  WRX and  Subaru Forester Toyota Tacoma  Toyota Tundra "The award process consists of evaluating 284 models through analysis of used-vehicle performance, brand outlook and product competitiveness," the announcement said. "Eligibility for a brand award requires a manufacturer to have model entries in at least four different segments. To account for differences across trim levels, model averages are weighted based on percentage share relative to the entire model line."   Audi Honda Hyundai Kia Land Rover Mercedes-Benz Subaru Toyota

Scion iA and iM rolled into Yaris and Corolla lineups for 2017

The Scion brand may be going away, but most of its cars (sorry, tC) are living on. We'll see the 2017 Toyota 86 (nee Scion FR-S) at the New York Auto Show next week, and the automaker already confirmed that the Scion iA and iM will be rebadged as Toyotas. But instead of standing on their own, the former Scions will be rolled into existing model lines. "Yaris iA" and "Corolla iM" will be the official names of the cars, effective for 2017. It's a smart move, paring the relatively new Scion nameplates with well-known, existing Toyota monikers. Scion spokeswoman Nancy Hubbell tells Autoblog that the iA already exists as the Yaris in the Canadian and Mexican markets, so "that connection was already there." Plus, it's better for marketing. The combination of the two vehicles all under the Yaris nameplate means Toyota can focus its advertising dollars on one vehicle line, simply saying that you can now have the Yaris as a four-door sedan or a five-door hatchback. "The same goes with Corolla," Hubbell explains. She says the existing Toyota sedan and the Scion iM "paired really well," and again, it means Toyota can advertise the Corolla as having two body styles moving forward. There are benefits from a sales perspective, too. Never mind that Scion division sales were already included in Toyota's overall numbers – calling the new cars Yaris iA and Corolla iM means the company won't have to report these cars individual sales separately. It's like when Toyota made the Matrix – its technical name was Corolla Matrix, so its individual sales didn't have to be broken out. That means an extra boost in overall numbers for the Yaris and Corolla, even if the cars would have been reported under Toyota's numbers had they kept their Scion badges. View 18 Photos Related Video:
