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.

2021 L.A. Auto Show roundup | All the reveals, reviews, pictures

The L.A. Auto Show took place this week for the first time since the onset of the pandemic. It was a show packed with news and reveals, which hasn't really been the case with other shows we've seen this year, and Autoblog was on the floor covering every minute of it. Well, Riswick and Stocksdale were, anyway. The rest of us were sitting at home in our sweatpants, but hey, we'll take credit anyway. Let's get to it. Hyundai Seven Concept This is the Hyundai Seven Concept, and it’s meant to act as a preview for an incoming electric SUV for the Ioniq brand. It leans more toward the concept side of the spectrum than a production car, but expect the final SUV to take design cues from the Seven Concept. Kia Concept EV9 The Hyundai Seven counterpart isn't the only big, bold electric SUV at L.A. this year. Kia has its own take, and it's a modernized version of the traditional boxy utility vehicle called the Concept EV9. It also previews one of the next production electric cars for the brand, which should look right at home next to things like the Telluride. 2023 Kia Sportage HEV As promised, the 2023 Kia Sportage HEV has been revealed. The hybrid powertrain makes the compact SUV the most powerful version available, and it goes on sale next year. The engine is a turbocharged 1.6-liter four-cylinder paired with a 44-kW electric motor. Total output is 226 horsepower. The company didn't give a torque number, but it should basically be the same as the Sorento HEV that has the same basic powertrain: 258 pound-feet. Those numbers are a healthy step up from the 187 horsepower of the base 2.5-liter engine. 2022 Range Rover If you noticed how extra smooth and suave the new Range Rover looked during its recent reveal, Autoblog's James Riswick got a design tour that revealed some of the technological secrets to its success. "Less is more" is harder to achieve than it looks. Fisker Ocean Fisker has brought the new Ocean EV to the L.A. Auto Show, with a public preview at Manhattan Beach and a presence at the show itself. You can watch the public show reveal above, and see more shots from the show floor below. Fisker says the Ocean will start at $37,499 before incentives. That entry model would be the Sport trim with a single, 275-horsepower motor driving the front wheels and 250 miles of estimated range. It also has a 0-60 time of 6.9 seconds. 2023 Toyota bZ4X This is the 2023 Toyota bZ4X, due to hit U.S.

Toyota investing $750M, adding 600 jobs at 5 U.S. plants

BUFFALO, W.Va. — Toyota on Thursday announced it is investing an additional $750 million at five U.S. plants that will bring nearly 600 new jobs, including the production of two hybrid vehicles for the first time at its Kentucky facility. It marks yet another expansion of the Japanese automaker's U.S. presence, bringing to nearly $13 billion the amount it will spend by 2021. The latest investments are at facilities in Alabama, Kentucky, Missouri, Tennessee and West Virginia. Those same facilities were part of a 2017 announcement by Toyota for a $374 million investment to support production of its first American-made hybrid powertrain. Toyota Motor North America CEO Jim Lentz said the latest investments "represent even more examples of our long-term commitment to build where we sell. By boosting our U.S. manufacturing footprint, we can better serve our customers and dealers and position our manufacturing plants for future success with more domestic capacity." Toyota's Georgetown, Kentucky, facility will get a $238 million infusion to produce hybrid versions of Lexus ES 300 sedans starting in May and the Rav4 SUV starting in January 2020, the company announced. It also includes $288 million to increase annual engine capacity at Toyota's Huntsville, Alabama, facility. The plant will add 450 jobs to accommodate new four-cylinder and V6 engine production lines. Last year Toyota and Mazda announced plans to build a $1.6 billion joint-venture plant in Huntsville that will eventually employ about 4,000 people. Toyota also is spending $62 million on equipment to boost production of Toyota and Lexus cylinder heads at its Bodine Aluminum facility in Troy, Missouri, as part of its cost-saving New Global Architecture production strategy to share common parts and components among different vehicles. A $50 million expansion and equipment upgrade at its Bodine plant in Jackson, Tennessee, will add 13 jobs and produce engine blocks while doubling the capacity of hybrid transaxle cases and housings. And Toyota will add 123 jobs and spent $111 million to expand its plant and purchase equipment in Buffalo, West Virginia, to double the capacity of hybrid transaxles. Previously, Toyota also announced a $600 million investment at its Princeton, Indiana, plant to increase the capacity of its Highlander SUV and to incorporate the new production strategy, and $170 million to launch the 2020 Corolla on a new production line in Blue Springs, Mississippi.
