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.

Toyota nudges US sales projections up to 2.25M

Toyota has raised its expectations for 2013's US sales for the third time since the end of 2012. The new target rests at 2.25 million units, when sales of Toyota, Lexus and Scion are taken as one. Subtracting Lexus, Toyota is still expecting to move over two million vehicles in the US by the end of 2013.
According to a report from Automotive News, the sales expectations came from Bob Carter, senior VP of automotive operations for Toyota USA, during a dealers during a meeting in Atlanta. The heightened expectations go along with Toyota's predictions for the US market as a whole, which it expects to grow to 15.5 million units by the end of 2013.
Besides an overall, national uptick in new vehicle sales, Toyota is also expecting a big push as it puts the next-generation Corolla to market during the second half of this year, along with the Tundra pickup truck. Meanwhile, dealers were shown images of a refreshed Camry, set to arrive in 2015, and reported that it's "more than a nip and a tuck," according to the AN report.

2013 Toyota Tacoma TRD Sport

"Oh yeah, Toyota still makes the Tacoma." Admit it, that's what you just said to yourself. It's a perfectly natural reaction, but the Tacoma has been quietly anchoring its segment for years, outselling every other compact pickup without making too much of a fuss. Toyota hasn't neglected the Tacoma - it was updated in 2012 with a revised nose and interior as the most noteable changes.
In a world awash with high-value fullsize pickups all vying for your attention, the Tacoma still charms more than a few buyers out of their cash. I hooked a Tacoma for a week to see whether it still has enough to recommend it.
