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.

2017 Toyota 86 Drivers' Notes | Fun, even with an automatic

The Toyota 86 is a car that enthusiasts begged Toyota to build for decades. It's small, lightweight and rear-wheel drive. Thanks to a partnership with Subaru that resulted in the BRZ, this stylish coupe hit the streets in 2012. In the U.S., the car was originally known as the Scion FR-S but was rebadged as a Toyota after Scion was axed last year. Along with a new name, the 86 received updated styling both inside and out as well as a revised suspension and a slight bump in power, at least for the manual models. This Hot Lava-colored car doesn't feature Toyota's slick six-speed manual. Instead it rocks a six-speed automatic with paddle shifters. While some enthusiasts may look down at that, automatics make up more than half of 86 sales. Still, the bones are there, and some people don't think the automatic is all that bad. Either way, we can't encourage enough people to buy these cars, as we want Toyota and Subaru to keep building them. Senior Editor, Green, John Beltz Snyder: When I first slid behind the wheel of the 86, I was surprised to see the gear selector and paddles. It's one of those cars that you don't think of as having anything but a manual transmission. Also, in an interior where all the controls and displays are underwhelming, a set of paddle shifters stands out as one of the few tactile objects in the cabin. I ended up using the paddles quite a bit, and found that I actually enjoyed using them, so much so that I'd actually consider opting for the automatic transmission were I to buy an 86. Despite shifts that aren't as razor sharp as they could be, the car's high-revving engine means that it still feels great to use. Riding an engine like this up to its redline, filling the cabin with noise, is the sort of thing that'll give you goosebumps. Being able to keep both hands on the wheel while shifting is a good thing for engagement in this car, based on my time with it. Plus, when I got stuck in traffic, I didn't have to wear out my left leg. The other brilliant thing about the Toyota 86 is its sense of balance. I loved the way it communicated its load distribution when cornering, whether on or off the throttle or brake. The fact that the nose of this car snaps right to where you want it when you start dialing in steering angle is satisfying. And its low stance and good view out the windshield make it really easy to place on the road.

Recharge Wrap-up: Control Tesla Model S from your wrist, NASCAR's E15 milestone

Tesla Model S owners can now control their car with Android Wear. A new, free app for the Android wrist devices, called Tesla Command, allows the user to control car functions such as the locks, horn, and sunroof from outside the vehicle. The developer promises more features are coming soon. Watch the video below for a demonstration, or head over to 9 to 5 Google to read more. NASCAR drivers have raced 6 million miles on E15 fuel. The stock car series reached the milestone on July 20 at Indianapolis Motor Speedway. NASCAR has been using Sunoco Green E15 gasoline since the start of the 2011 season, which the group credits with increasing horsepower and reducing emissions. The US Department of Energy notably approved the 15-percent corn ethanol blend after 6 million miles of testing. Read more at Domestic Fuel. The Pennsylvania Department of Environmental Protection has decided to continue its incentive program for alternative fuel vehicles. Buyers of electric vehicles and plug-in hybrids with batteries larger than 10 kWh will continue to get a $2,000 rebate (until December 31 or until 500 are sold, whichever comes first). Various EVs with batteries less than 10 kWh, as well as natural gas, propane and hydrogen-powered cars, will get $1,000 back. Electric motorcycles and scooters are offered a $500 rebate. Get more details at ABC 27. Toyota subsidiary Primearth EV Energy is set to expand production of nickel metal hydride batteries for hybrid cars. Due to high demand, production capacity will ramp up from 300,000 to provide batteries for 500,000 vehicles at its Miyagi prefecture plant. The company eventually plans to be able to produce batteries for 1.4 million hybrids per year. Primearth EV Energy currently supplies batteries for the Toyota Prius and Yaris hybrids, as well as Mazda's Axela (AKA Mazda3 in the US) hybrid. Read more at Economic Times.
