Impala crashes into Land Cruiser... to hide from a cheetah

What would you do if a wild animal jumped into your vehicle through an open window during an African safari? What if said animal was an impala being chased by cheetahs? Though the scenario seems unbelievable, that's just what happened to a group of tourists in Kruger National Park in South Africa, and it was all caught on video.
With the tour groups stopped, a motorist with a video camera handy happens to catch the unlikely sight of a herd of impalas (not that kind of Impala) jumping over the tarmac while being followed, quickly of course, by two cheetahs. The feline predators thought they had cornered one impala and were closing in for the kill when it jumped through the open window of a Toyota Land Cruiser Prado - South Africa's version of the Lexus GX. Fortunately for the occupants of said vehicle, the cheetahs did not follow.
A short while later, one of the occupants in the Toyota fearlessly opens a door to let the poor animal out. It must have been its lucky day, because the cheetahs didn't take pursuit. Check out the circle life get interrupted by this traffic jam in the video below.

Toyota wants half its vehicles in Japan to be hybrids

The Toyota Mirai hydrogen fuel cell vehicle could signal the future of motoring with a somewhat accessible price and cutting-edge green technology, but there's no guarantee for the model actually spearheading a revolution in the marketplace. In the meantime, the Japanese brand is continuing to focus on its hybrid powertrains and actually plans to build even more of them. As soon as next year, half of Toyota's sales in Japan could be electrically assisted. According to the Nikkei Asian Review, Toyota is pushing to sell 760,000 hybrids in Japan in 2016, compared to 684,000 last year. That figure would account for half of the company's sales in that country, and the company plans to increase overall production of its gas-electric models. The automaker could build 1.32 million of them next year, which would be about 30 percent more than in 2014. There's actually a financial incentive for Toyota to try this green strategy. Japan's rules for tax breaks on efficient models are about to get more stringent. According to the Nikkei Asian Review, only about half of all new models are expected to meet the guidelines for the incentives, compared to over 80 percent now, and the change could cost buyers as much as 100,000 yen ($840) more. With the impending debut of the next-gen Prius and heightened hybrid production, Toyota can position itself as an attractive choice to customers.

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.
