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 expands airbag recall to 2.27M vehicles worldwide

Was your Toyota inspected under the company's recall campaign for faulty airbag inflators last year? You might have another trip ahead to have it repaired again. The automotive giant says that it found "the involved serial numbers provided by the supplier were incomplete, and did not include all of the potentially involved inflators," according to its official announcement. That means more replacements are needed.
Toyota's April 2013 inflator recall covered the Corolla, Matrix and Tundra from the 2003 and 2004 model years, the Sequoia from 2002 to 2004 and the Lexus SC 430 from 2002 to 2004. At the time, the company said it would need to inspect about 510,000 vehicles in the US but only expected to replace around 170,000 inflators.
However, the latest announcement increases that figure to about 766,300 vehicles in the US. Toyota spokesperson Cindy Knight told Autoblog that the new amount is the combination of owners who need to have their vehicle looked at again and those who didn't come in for the initial recall. The company learned about the problem when Takata, the supplier, provided it with an improved list of the faulty part's serial numbers. According to The Detroit News, the latest recall affects about 2.27 million vehicles from them worldwide. Knight said owners would receive notification of the problem around the end of the month but repairs would come in phases because the automaker doesn't have all of the necessary parts at the moment.

2020 Toyota Highlander vs other 3-row crossovers: There can only be one!

We've done quite a few spec comparison posts involving three-row family crossovers, and when included, the Toyota Highlander has always been the runt of the group. While the rest increasingly seemed to be benchmarking each other toward greater girth, the Highlander was the outlier.  That changes a bit for the 2020 Toyota Highlander, but only a bit. It's now larger and more competitive, specifically in regards to the amount of cargo space aft of the third-row seat. As you can see below, this aligns the Highlander most closely to its long-time competitor the 2020 Honda Pilot. However, let's see how it stacks up to others in the segment, which is heavily populated now, so for the sake of space, we've selected the newest entries: Kia Telluride, Hyundai Palisade, Subaru Ascent and Ford Explorer. The order in which they are presented is random.  Performance and fuel economy The 2020 Highlander is more than 200 pounds lighter than its predecessor, but has the same 295-horsepower V6 engine that was already one of the strongest in the segment. We'd say that would give it a leg up, but the Pilot and Explorer have proven to be sprinters, delivering 0-60 times in the low-6 range by some publications' stopwatches (or VBoxes, whatever). We don't expect the Highlander to beat them, but it may dip into the 6's. The heavy, less-powerful Subaru Ascent is most likely to take up the rear. It's fuel economy of 23 mpg combined also matches the Highlander and Explorer for segment-best. Remember, however, that the Explorer's turbocharged inline-four engine is likely more susceptible to differences in driving style (read: a heavy foot).  Of course, if you're really interested in fuel economy, the Highlander and Explorer are the only vehicles in the segment to offer hybrid versions. The Ford Explorer Hybrid puts a greater emphasis on performance, however, resulting in lower estimates of 25 mpg combined (AWD) and 28 mpg combined (FWD). By contrast, the new 2020 Toyota Highlander Hybrid is estimated to return 36 mpg combined.  Passenger and cargo space According to Highlander chief engineer Yoshikazu Saeki, he had a choice of two directions with the new Highlander. He could have indeed made it bigger, matching these very competitors, especially in terms of third-row and cargo space. Or, he could have maintained a smaller-than-average size. He obviously chose the latter. First, it was the size customers had come to expect. Would they be put off by something bigger?
