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. Read more in the press release below. 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 has two all-new 8-passenger SUVs in the works, and one's a Lexus

Toyota announced yesterday that its Princeton, Indiana, manufacturing plant is getting a big $803 million infusion of cash. The reason? Toyota casually dropped that it will soon build “two all-new, three-row SUVs” there. TheyÂ’ll be “designed with the active Gen Y American Family in mind,” which is another way of saying that Toyota is targeting Millennials. In case you missed it, Millennials are in their late 20s and 30s now! That means they have growing families and need more space to put them. Both new SUVs will seat up to eight passengers. The other big reveal is that both will be electrified. WeÂ’re going to assume that means theyÂ’ll be regular hybrids in ToyotaÂ’s case, though thereÂ’s every possibility for a PHEV “Prime” version, too. Both will have semi-automated driving systems, advanced enough that they will “allow for hands-free driving in certain conditions.” Plus, there will be a remote parking system that allows “the driver to park and unpark outside the vehicle using a smartphone.” The last nugget of tech Toyota is sharing with us is that both will use a new “digital key” that turns your smartphone into a quasi key and allows you to share it digitally with others. Another bit of information concerning these two is that one will be a Toyota, and the other will be a Lexus. What these two models will be named is not yet clear. Seeing “three-row SUV,” our minds instantly go to Sequoia. That model is as old as it gets these days, and is deeply in need of a redesign — the current generation launched all the way back in 2008. However, Toyota does not explicitly say that this news pertains to the next-gen Sequoia. In fact, previous reports of the Sequoia shifting its production location to San Antonio lead us to believe that this news has absolutely nothing to do with a potential next generation of the SUV. Coincidentally, the Sequoia is currently built at the Princeton, Indiana, plant thatÂ’s getting this investment — that official switchover to Texas is reported to happen sometime in 2022.  ToyotaÂ’s language in this press release, plus the knowledge that Sequoia is leaving Indiana, all indicates that these two three-row SUVs might not be rough-and-tumble body-on-frame off-roaders. TheyÂ’re likely going to be plenty capable (hitting that “active lifestyle” market), but the focus toward families suggests that comfort could be paramount.

Toyota rolls out all-new HiLux pickup Down Under [UPDATE]

Never heard of the Toyota HiLux? That could be because it's not sold in America. But it's been around in other markets for 47 years now, over the course of which it has sold over 16 million units. Suffice it to say, then, that the HiLux is a vital product for the Japanese automaker, so the introduction of the new model you see here is a big deal on a global scale. The eighth-generation HiLux is the first all-new one in a decade, and benefits from some substantial improvements. It's touted as tougher and more capable than the ten-year-old model it replaces, but also safer and more comfortable. It boasts more interior space, a larger fuel tank and greater hauling capabilities. In the right spec, it'll tow more than 7,700 pounds and carry up to 2,700. There's a staggering array of configurations to choose from: 31 in all, resulting from two drivetrains, two transmissions, four engines, three cabin sizes and three levels of trim (in Australia at least - see update below). The top 4.0-liter V6 carries over and the 2.7-liter four has been upgraded for higher output and efficiency, but there are two new common-rail turbo-diesels on offer: a 2.4 with 164 horsepower and 295 pound-feet of torque, and a 2.8 with 174 hp and 332 lb-ft. They're mated to new six-speed manual and automaker transmissions, and buyers in the many markets where the HiLux contends will also be able to select a new Hi-Rider model that combines two-wheel drive with the ride height of the 4x4. The new HiLux is being introduced today in both Thailand and Australia, which are hardly random choices for the new model's debut. Though the truck is manufactured in six countries around the world, the Thai plant alone accounts for 70 percent of its production. And in Australia, the HiLux has not only been the top-selling commercial vehicle for the past 17 years running, but stands as the country's most popular vehicle of any kind – making it Oz's equivalent to our Ford F-150. UPDATE: While the HiLux is clearly a vital product for Toyota in the land Down Under, that's not the only place where it will be sold - and the details listed above will change from market to market. "Specs will differ across the globe, including engine availability," a spokesman for Toyota in Europe told Autoblog. The company's Australian PR rep confirmed that "Each region has its own unique requirements. Engine specs change based on emissions requirements for instance.
