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.

New Toyota Supra may get a twin-turbo Lexus V6

We've heard endless rumors that a successor to the much loved and much missed Toyota Supra is in the works. Toyota hasn't done much to deny these conversations. On the contrary, the FT-1 concept from two years ago and the partnership with BMW have only fueled the fire. Now, talk of a new Lexus engine has led to speculation about the supposed Supra's powertrain. To be clear, this is mostly heresay. Few things have actually been confirmed, but based on what we know a few conclusions can be drawn. We know that BMW and Toyota are working on a joint product. We've seen mules testing out in the wild. In BMW guise, the possibly Austrian-built car will more than likely powered by turbocharged inline four and six-cylinder engines. Unless Toyota wants to use Bimmer power, they'll need to shoehorn one of their own under the hood. That leads us to this rumor of a twin-turbocharged V6 that will presumably power the new Lexus GS and LS. Japanese automotive publication Mag-X first reported on this engine. It was then picked up by YouWheel and Car Keys. Mag-X cites Toyota insiders and even gives an engine code, 943F. This engine allegedly will make more than 400 horsepower and more than 300 lb-ft of torque. While unconfirmed, this makes sense for Lexus. Nearly every luxury competitor has a six-cylinder engine with forced induction. While Toyota has previously had turbocharged inline-sixes, they've never produced a factory turbo V6. Every automaker is downsizing engines in an effort to meet fuel economy and emissions regulations. Toyota and Lexus will follow suit. Taking that V6 and tuning it for a performance application is a solid, if unverified, possibility. Related Video:

April Fools' Day brings Jeep Sedan, Hyundai N Roadster, Toyota Yaris pickup and more

There is one day out of the year when public relations professionals have permission to lie to journalists and to the public: April Fools' Day. Manufacturers release details about wild, weird and wacky new technology, concept vehicles and services. Some take it to obvious outlandish extremes (Jeep Sedan anybody?), while others plot to mislead with products that are just outside the realm of possibility. Check out all the "jokes" below. BMW Motorrad BMW doesn't want to exclude anybody from experiencing the thrill of high-level racing, so it is introducing 'iRace" autonomous programming on its S 1000 RR sport bike. It includes beginner, sportsman, advanced and unlimited driving modes, and stores GPS information for all Superbike world championship tracks. Hyundai Hyundai is wrong for this. The Hyundai N Roadster is the work of South Korean designer Yeonjoon Park and features a 2.0-liter turbocharged engine, rear-wheel drive and a hard convertible top. Hyundai says this is a "concept (for now)," but we think it'd make a seriously great Mazda Miata competitor. Honda Honda wins the award for the best interactive gimmick, as its press release for the '90s-inspired special-edition Pastport includes a live hotline number with a message from Fred Savage. Call 1-833-PASTPORT for more information. Jeep Put the Jeep Cherokee face on the Chrysler 300's body, and voila! The 2019 Jeep Sedan is born. We can't decide if the name or the rendering is better. Land Rover Accessibility to charging ports is of major concern to anybody with a plug-in vehicle. So, with the recent launch of the Range Rover P400e and Range Rover Sport P400e, Land Rover is putting forth an effort to install more stations around the globe. First up is Scotland's Isle of Skye. Adventurers need juice too! Lexus Australia Lexus expands its Encore service to include doggos. The new service, called Enpaw, will take pups to luxury boarding kennels in style. Toyota U.S. Toyota created the Yaris Adventure pickup for "those who want to tell their friends they own a truck but never veer off pavement." It's part Mazda 2, part RAV4, 100 percent ute and it looks ... great? Creating a new segment might be all fun and games to Toyota, but Ford is reportedly considering a Focus-based ute in a similar, albeit larger, style. Toyota Australia Toyota is launching a new HiAce van, and it's already getting a limited-edition variant called the PieAce.
