Next Toyota Prius may get optional all-wheel drive

We've been hearing rumors about the next generation of the Toyota Prius for the last couple of years on a pretty regular basis. From the expectation of lithium-ion battery packs with more capacity for electric-only miles to wireless charging and more emotional styling, there's been no shortage of talking points for the car that's expected to see its first light of day at the very end of 2015 (we hope). But one thing we've yet to hear about, until now that is, is all-wheel drive. According to a report from Automotive News, Koei Saga, senior managing officer in charge of powertrain development of the Prius, said in an interview last week, "I think we will possibly do [all-wheel drive]" for the car's next generation. There isn't any further indication on how the AWD system would work, but we'd put our money on something similar, at least in principle, to the E-Four system that just debuted on the 2015 Lexus NX 300h, which uses an electric motor mounted at the rear to power the car's back wheels when the front wheels lose traction. The AN report also repeats a rumor we've heard before – that Toyota may offer two different battery pack options in its next Prius, one using lithium-ion chemistry and one using the nickel metal hydride technology that the Prius has featured from its very beginning. While the automaker has yet to talk efficiency, it's natural to expect more capacity for EV driving from newer lithium-based technology over that of nickel-based packs to go along with what we'd also expect would be a somewhat higher price. We're sure you're just as curious about the next Prius as much as we are, and so we'll leave you with these words, again from Saga: "The batteries will be renewed. Everything will be revised. And I think we will come up with a fuel economy that will surprise everyone."

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.

Mazda CX-5 named Japan's Car of The Year, Subaru BR-Z wins "Special Award"

The Mazda CX-5 stamped its Kodo design and SkyActiv technology authority all over the Japan Car of the Year awards, taking the top prize ahead of the Subaru BRZ/Toyota GT 86. It is Mazda's second victory in the last ten years, the 2005 MX-5 claiming the same trophy, and the fourth time the Hiroshima company has won.
The award is decided by 60 local "automotive experts and journalists," and open to any passenger car released in Japan from November 1, 2011 to October 31, 2012 that has sold more than 500 units. Each judge gets 25 votes, his or her top vote getting 10 points, the rest of the points being spread among the judge's choice for the next best four cars.
The second-place getters were the Toyobaru twins with 318 votes, the surprise being they didn't beat or get any closer to the crossover. The Subaru BRZ did claw some mojo back, earning the Special Award given to cars that have made "an exceptional impact." The BMW 3 Series was third overall and won the Import Car of the Year award with plenty of room between it and the second place Range Rover Evoque.
