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.

Driving the new Prius Prime, Lordstown goes bankrupt and the march to NACS | Autoblog Podcast # 787

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Road Test Editor Zac Palmer. They start the show by talking about the cars they've been driving. Zac spent time in the 2023 Toyota Prius Prime and 2023 Jeep Compass, while Greg chats about his week in the 2023 Cadillac CT5-V and 2023 Hyundai Santa Fe Calligraphy. Next, they hit the news and chat about Lordstown's bankruptcy, Volvo (and others) adopting Tesla's NACS port and the revealed presence of a BMW M5 Touring. Finally, they conclude with the Spend My Money segment where a listener is looking for help finding a new EV or PHEV.

10% of Toyota China dealers may drop due to losses

News about the auto industry in China is usually positive thanks to booming sales and an ever-increasing number of factories across the country. But in some cases, it appears that the dealers with the job of actually selling all of those vehicles are having trouble finding buyers. The result is cars piling up on lots and showrooms resisting against automakers. Japanese automakers already face a tough road to success in China, but the FAW-Toyota joint venture is especially struggling this year. According to Bloomberg, as many as 10 percent of the dealers might have to close or stop selling the brand because they just can't make money selling the vehicles on their lots. Also, 95 percent of the showrooms are reportedly losing money. The issue facing FAW-Toyota sellers is mostly a case of supply and demand. Automakers in China mandate the number and types of vehicles that dealers sell. However, the inventory from all makes is at its highest level since August 2013, according to Bloomberg. The situation leaves dealers with packed lots, and cars often require discounts to move. Making matters harder is that showrooms have annual sales targets, which are linked to bonuses. This money can account for over half of the sellers' annual profits, according to Bloomberg. The FAW-Toyota dealers are pushing back by asking Toyota for 2.2 billion yuan ($355 million) to pay for costs associated with the extra inventory. It also lowered sales targets by six percent earlier this year and has requested no increase in the numbers for 2015.
