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.

Ford Fiesta ST in startling track battle against Toyota GT86

On the surface, there's very little that the Ford Fiesta ST and Toyota GT86 (or the Scion FR-S that is sold in the US, or the largely similar Subaru BRZ) share in common. One is a hatchback with power coming from a turbocharged engine routed to the front wheels. The other is a coupe with power coming from a naturally aspirated four-cylinder boxer engine routed to the rear wheels.
Thing is, both of them are reasonably priced performance cars aimed at a similar segment of the automotive marketplace, so a comparison isn't out of the question. It is with all of this in mind that we direct you to the video below, in which the blokes from Evo pit the two manic little machines against one another on a race track. The result? Well, it can be summed up this way: Fast versus fun.
See how the track battle goes down in the video below.

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.
