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.

Consumer Reports says infotainment systems 'growing first-year reliability plague'

The Consumer Reports Annual Auto Reliability Survey (right) is out, and the top two spots look much the same as last year's list with Lexus and Toyota in first and second place, respectively. However, there are some major shakeups for 2014, with Acura plunging eight spots from third in 2013 to 11th this year, and Mazda replaces it on the lowest step of the podium. Honda and Audi round out the top five. This year's list includes six Japanese brands in the top 10, two Europeans, one America and one Korean.
Acura isn't the only one taking a tumble, though. Infiniti is the biggest loser this year by dropping 14 spots to 20th place. Other big losses come from Mercedes-Benz with an 11-place fall to 24th, and GMC, which declines 10 positions to 19th.
Perhaps unsurprisingly, it's not traditional mechanical bugs hauling down these automaker's reliability scores. Instead, pesky problems with infotainment systems are taking a series toll on the rankings. According to Consumer Reports, complaints about "in-car electronics" were the most grumbled about element in new cars. Problem areas included things like unresponsive touchscreens, issues pairing phones and multi-use controllers that refused to work right.

Car technology I'm thankful and unthankful for

The past few years have seen a surge of tech features in new vehicles — everything from cloud-based content to semi-autonomous driving. While some of it makes the driving experience better, not all tech is useful or well thought out. Automakers who are adept at drivetrains, ride quality and in-cabin comforts often fail at infotainment interfaces and connectivity. From testing dozens of vehicles each year and in the spirit of gratitude, here are three car tech features I'm thankful — and a trio I could live without. Thanks Connected search: This seems like a no-brainer since everyone already has it on their smartphones, but not all automakers include it in the dashboard and as part of their nav systems. The best ones, such as Toyota Entune, leverage a driver's connected device to search for a range of services and don't charge a subscription or require a separate data plan for the car. I also like how systems like Chrysler Uconnect use Yelp or other apps to find everything from coffee to gas stations and allow searching via voice recognition. Apple CarPlay and Android Auto: It took two of the largest tech companies to get in-dash infotainment right. While they have their disadvantages (you're forced to use Apple Maps with CarPlay, for example), the two smartphone-integration platforms make it easier and safer to use their respective native apps for phoning, messaging, music and more behind the wheel by transferring a familiar UI to the dashboard — with no subscription required. Heated seats and steering wheels: I really appreciate these simple but pleasant features come wintertime. It's easy to get spoiled by bun-warmers on frosty mornings and using a heated steering wheel to warm the cold hands. I recently tested a 2018 Mercedes-Benz E400 Coupe that also had heated armrest that added to a cozy luxury experience. Bonus points for brands like Buick that allow setting seat heaters to turn on when the engine is remotely started. No thanks Automaker infotainment systems: Automakers have probably poured millions into creating their own infotainment systems, with the result largely being frustration on the part of most car owners. And Apple CarPlay and Android Auto coming along to make them obsolete. While some automaker systems, such as Toyota Entune and FCA's Uconnect, are easy and intuitive to use, it seems that high-end systems (I'm looking at you BMW iDrive and Mercedes-Benz COMAND) are the most difficult.
