Toyota sells off Tesla shares, too

The incredible rise of Tesla's stock price has done little to now stop two major shareholders from ditching their stake in the American EV manufacturer. First, Daimler, parent company of Mercedes-Benz, ditched its four-percent stake, and less than a week later, Toyota is doing the same thing, selling off an undisclosed bit of its Tesla investment.
The move comes as Toyota winds down sales of the RAV4 EV, which gets its batteries and electric motor from Tesla at the company's Fremont, CA factory.
"We have a good relationship with Tesla, and will evaluate the feasibility of working together on future projects," Toyota spokesperson Kayo Doi told Bloomberg via email.

Successor to the Toyota 86 is on the way

Until now, Toyota and Subaru have been mum on the prospect of a follow up to the Toyota 86 and Subaru BRZ. Although both cars received mild refreshes and even milder power bumps, they're both essentially the same cars that hit the market nearly five years ago. It appears a successor is indeed on the way, as Autocar confirms that Toyota is developing a next-gen 86. Karl Schlicht, executive vice-president at Toyota Motor Europe, said that the 86 will live on past the current generation. "The car serves a big purpose," Schlicht said. "We are not getting out of that business. Sporty cars go through their phases. It's our intention to continue with that car." Toyota seems to be back in the sports car business, as the company has partnered with BMW on a new Supra. Like the current Toyota 86, it seems likely that the successor will be co-developed with Subaru. Schlicht says that to get the low center of gravity and the handling characteristics that come along with it, a horizontally opposed engine is a necessity. He admits that there is no firm confirmation of a commitment from Subaru. While no Schlicht gave no details about the new car, he did nix any possibility of a convertible variant. "We wouldn't do it on the current model," he said. "That doesn't mean dealers wouldn't like one, but there are so many other priorities that I don't think we've got spare capacity for that."

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.
