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.

Toyota GT86 14R-60 shows how to do lightweight at a steep price

Toyota is finally making good on its Griffon concept from last year with this limited-edition 14R-60 that basically hops through the Toyota Racing Development catalog to imagine the ultimate lightweight GT86 (the continental relative to the Scion FR-S/Subaru BR-Z). Unfortunately, it's not coming stateside, and even if this modded Toyobaru were coming here, you might not want to pay the rather steep price.
Like the concept, the 2.0-liter boxer engine still makes the same 197 horsepower and 151 pound-feet of torque. However, the drivetrain isn't entirely untouched thanks to a new air filter, engine oil cooler, a reinforced clutch, lightweight flywheel, and mechanical limited-slip differential from TRD. The six-speed transmission is also tweaked, with different gearing in first and second and an altered final drive ratio.
To keep things planted the suspension gets a new coilovers, a V-shaped tower brace in the front and another in the rear. Improved deceleration comes thanks to upgraded brakes. There also are even more goodies on the outside, including a complete body kit that includes a carbon-fiber roof and massive rear spoiler. The stock wheels are replaced with 18-inch forged magnesium units, as well.

Toyota announces GT86 CS-R3 rally car

Toyota Motorsport GmbH has developed cars for all manner of racing, up to and including Formula One and Le Mans. But it got its start back in 1979 in rally competition, winning four drivers' and three manufacturers' titles in the World Rally Championship. And now it's announced a new rally car.
Based on the Toyota GT86 (better known to us as the Scion FR-S), the CS-R3 rally car isn't built to contest the top tier of the WRC, but is being developed to conform to the lower R3 class. That means a six-speed sequential gearbox, limited slip differential and upgraded engine, brakes, aero... the works. It'll retain the road-going model's rear-drive setup, joining the front-drive Yaris R1A in TMG's portfolio of customer rally cars.
Further details are set to be revealed "in the coming months", but the GT86 CS-R3 will benefit from the experience TMG accrued in developing the GT86 CS-V3 (pictured above) for the Nürburgring-based VLN endurance racing series.
