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.

JLR shares backstage 'No Time to Die' Range Rover Sport SVR carnage

James Bond's latest adventures will take him to Norway and Scotland, as seen in the trailer for the upcoming "No Time to Die." Somewhere along the way, the British spy encounters a pair of Range Rover Sport SVRs, the ultimate high-performance SUV from JLR's Special Vehicle Operations division in one of the movie's centerpiece car chases. Now, the company has given us a behind-the-scenes look at its filming, and the automotive carnage that ensues. The filmmakers wanted to take a Bond action sequence off-road, and chose the Range Rover Sport SVR as the the bad guys' pursuit vehicle. Armed with a JLR product placement deal (Bond drives a new Defender in another part of the movie) the henchmen had no qualms picking one of the most expensive things on the menu. Unfortunately, that also makes is a bit hard to watch when machines that start at $115,000 are totaled as they careen through the air or roll onto their roofs. The SVRs share a 5.0-liter supercharged V8 with the Jaguar F-Type SVR and are the most powerful vehicles in the Land Rover portfolio. With 575 horsepower and 516 pound-feet of torque on tap, translating to a 0-60 time of 4.3 seconds, they're the perfect weapon for chasing a super-spy down a dirt road. As for Bond himself, 007 makes his escape in a decades-old yellow Toyota Land Cruiser Prado. Specifically, it's a 90-series, a smaller version built from 1996 to 2002 that was never sold in the U.S. but remains popular in other parts of the world. The most powerful engine had just 190 horsepower from a 3.4 liter V6 shared with the similar-era 4Runner. Despite the power discrepancy, Bond manages to dispatch the Range Rovers in spectacular fashion. Wait, this is a Range Rover promo, right? "All the stunts are for real, there's nothing that's CGI'ed," said Neil Layton, the film's action vehicle coordinator. "So to make the cars more dramatic on the screen, we had to turn off a lot of safety feature aids that's on there." Interestingly, another non-JLR product shows up in the video as well. The camera car is a blacked out (to minimize reflection in other cars) Ford F-150 Raptor outfitted with a massive rooftop boom. "No Time to Die" is hits the screens on October 8.
