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.

2018 Technology of the Year Award | We chat with Lexus about the LC 500h's hybrid system

Every year, Autoblog editors test dozens and dozens of the newest vehicles available, sometimes even before they're available. From those vehicles, we select the ones we think provide the most innovative technology in the industry. Then we pare the list down to the very best, test them again, and vote on our winner for Technology of the Year. This year, Lexus's multi-stage hybrid system — as tested in the LC 500h — came out ahead of the rest of the finalists. We chose the 2018 Detroit Auto Show to hand over the award to Lexus Group Vice President and General Manager Jeff Bracken. He was kind enough to sit down with Autoblog Senior Editor Alex Kierstein and Green Editor John Snyder at the Lexus stand to talk about the hybrid system, what it does, and what it means for the future of Lexus and Toyota. Check out the video above, and follow along for all our coverage from the 2018 North American International Auto Show in Detroit, where we are taking a look at all of the new cars and technology that we'll see in the near future. Perhaps the next winner of Autoblog's Technology of the Year award is sitting somewhere on the Detroit show floor.

5 highlights from the 2018 Petersen Automotive Museum Auction

From the avant garde exterior design to the collection of vehicles between the walls, the Petersen Automotive Museum in Los Angeles is one of the coolest car museums in the U.S., and possibly the world. Among several others, the Petersen has two featured exhibits, The Porsche Effect and Legends of L.A. But the museum has a different type of viewing coming up at which you could touch, or even buy, a variety of special vehicles. After hosting its SoCal auction on the coast in Santa Monica for several years, RM Sotheby's has moved the event to the more central location of the museum. In addition to several works of art, the auction which takes place the weekend of December 7, will show several dozens of blue-chip vehicles, chosen by RM Sotheby's 30 car specialists. After sorting through lots that range from microcars to new-age supercars, here are five of the highlights that caught our eyes. 1956 Ferrari 290 MM by Scaglietti Projected Value: $22,000,000-$26,000,000 Without question, this is the crown jewel of the entire show. As the eldest and most experienced of the 11 total Ferrari lots, its estimated value of $26 million is more than five times the values of the other five cars listed below combined. From the jump, Ferrari threw the 290 into the line of fire. Starting its life with a four-cylinder 860 Monza engine and a Tipo 520 chassis, its first race was the Mille Miglia. Peter Collins was behind the wheel and racing photographer Louis Klemantaski was his copilot. Ferrari took the top five spots in the race, with this car, chassis No. 0628, finishing second. It went on to see multiple races and took on multiple forms, including a V12 swap at one point. After switching through the hands of multiple owners, it was sent to Ferrari Classiche in Maranello, where it was restored to its form at the time of the 1957 12 Hours of Sebring. It retains its original chassis, original bodywork, and original transmission, and houses the V12 from its 290 MM spec. The restoration was completed in 2015, and the car remains in incredible shape today. 1971 Lamborghini Miura P400 SV by Bertone Projected Value: $2,100,000-$2,500,000 Simply put, the Miura is one of the most significant supercars, and therefore one of the most important cars, of all time. Its two-seat, mid-engined configuration seismically shifted what a performance could and should look like, and its V12 gave it the power to be the fastest car in the world when it debuted.
