Toyota GT86 CS-R3 rally car presages for-sale customer racecar

Rallying may enjoy a very strong association with all-wheel drive, but it wasn't so long ago that the World Rally Championship was populated by cars that slipped and slid across gravel and tarmac using rear-wheel drive. One of those was the Toyota Celica. While the little Celica eventually joined the gravel-spewing masses with an all-wheel-drive rally car, Toyota is returning to its rear-drive rally roots with a modified version of the critically acclaimed GT86.
Called the CS-R3, the new model boasts all the necessary changes to turn the diminutive twin of the Scion FR-S and Subaru BRZ into a car capable of tackling the tough, twisting paths that are so routinely conquered by the world's rally cars. That means, of course, the CS-R3 has gotten a power bump.
Expected output sits between 240 and 250 horsepower, thanks to a new racing exhaust and manifold, as well as other changes. The ECU has been replaced with an item a bit more suited to racing, while the compression ratio has also been adjusted to boost the output.

Krafcik says US Gov. shutdown is slowing Oct. auto sales

The government shutdown is eroding consumer confidence in the auto market, says John Krafcik, CEO of Hyundai's US sales unit, and could lower October sales by as much as 10 percent, Automotive News reports. "It's that anxiety that keeps customers, potential buyers, on the sidelines when making a big purchase like an automobile," Krafcik says, adding that industry sales could be off by five to 10 percent in October compared to September.
The fourth quarter, which started October 1, usually consists of increased auto sales as dealerships clear their lots to make room for the next year's models. Leading up to the fourth quarter this year, the auto industry was doing well in the fragile, recovering US economy, although September deliveries decreased by 4.2 percent, due in part to this year's Labor Day sales being recorded for August.
To help its customers, Hyundai announced it is deferring new-car loan and lease payments for furloughed federal workers until they're called back to work and also offering them a three-month payment deferral if they buy a new Hyundai in October. "We have already had requests from over a thousand people to have their payments deferred," Krafcik says.

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.
