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.

Average transaction prices climb to a record $36,270 in January

The automotive sector made a hash of the numbers last month, a mess of pluses and minuses clogging the transaction-price charts according to Kelley Blue Book. The overall industry rose one percent, even though buyers bought fewer cars and light vehicles in January 2018 vs 2017 using the selling-day adjusted rate. Due to January transaction prices rising to $36,270, a record for January, the value of new vehicles sold climbed more than $1 billion compared to January 2017. KBB's transaction prices don't include customer incentives, which changes the complexion slightly; average incentive spending rose to just over ten percent. The average transaction price in December 2017 was $36,756, so January dropped a bit - nothing unexpected, with the month annually blamed for "January doldrums." More revealing is the fact that the average transaction price in January 2017 was $34,910. This year's plumped-up figure came courtesy of the continued shift to crossovers, SUVs, and light trucks, which shouldn't surprise anyone who's read an automotive blog in the past 20 years. That category comprised nearly 70 percent of new vehicle sales for the month. Some manufacturers profited more than others, though. Fiat Chrysler managed 12.8 percent fewer sales in January compared year-on-year, but the company's vehicles sold for $1,300 more. The Ford brand suffered a 6.3-percent dip in sales, but brand transaction prices increased $2,000, while a Lincoln sold for $8,700 more on average. General Motors sold more cars and sold them for more money; overall GM transaction prices rose four percent, or $1,270, while a GMC traded hands for seven-percent more than in January 2017 and a Cadillac got $2,300 more on average. Of KBB's listed automakers, the Volkswagen Group got the most of out its customers, transaction prices rising at the German automaker by 5.6 percent to $42,243 in January 2018 compared to a year earlier. American Honda followed with a 4.3-percent increase to $28,991, GM in third at 4.1 percent to $40,313. Find your next car at Autoblog using our new and used car listings or the Car Finder tool. Broken out by segment, minivans rocked the table, transaction prices leaping by 7.9 percent to $35,380 compared to January a year earlier. Luxury cars boasted the next-highest rise, at 3.6 percent to $58,533.

Recharge Wrap-up: Control Tesla Model S from your wrist, NASCAR's E15 milestone

Tesla Model S owners can now control their car with Android Wear. A new, free app for the Android wrist devices, called Tesla Command, allows the user to control car functions such as the locks, horn, and sunroof from outside the vehicle. The developer promises more features are coming soon. Watch the video below for a demonstration, or head over to 9 to 5 Google to read more. NASCAR drivers have raced 6 million miles on E15 fuel. The stock car series reached the milestone on July 20 at Indianapolis Motor Speedway. NASCAR has been using Sunoco Green E15 gasoline since the start of the 2011 season, which the group credits with increasing horsepower and reducing emissions. The US Department of Energy notably approved the 15-percent corn ethanol blend after 6 million miles of testing. Read more at Domestic Fuel. The Pennsylvania Department of Environmental Protection has decided to continue its incentive program for alternative fuel vehicles. Buyers of electric vehicles and plug-in hybrids with batteries larger than 10 kWh will continue to get a $2,000 rebate (until December 31 or until 500 are sold, whichever comes first). Various EVs with batteries less than 10 kWh, as well as natural gas, propane and hydrogen-powered cars, will get $1,000 back. Electric motorcycles and scooters are offered a $500 rebate.

Due to high demand, production capacity will ramp up from 300,000 to provide batteries for 500,000 vehicles at its Miyagi prefecture plant. The company eventually plans to be able to produce batteries for 1.4 million hybrids per year. Primearth EV Energy currently supplies batteries for the Toyota Prius and Yaris hybrids, as well as Mazda's Axela (AKA Mazda3 in the US) hybrid. Read more at Economic Times.
