Cleanliness of Toyota Mirai fuel cell exhaust depends on air quality

Is the water vapor coming out of Toyota's first production fuel-cell vehicle drinkable? If you're driving through the Sierra Nevadas? Probably. Cruising through Beijing? Not so much. Toyota executive Seiji Mizuno discussed whether the water vapor emitted from the Toyota Mirai is safe enough to drink and, according to Automotive News, the short answer is "yes," since the slightly-acidic vapor has "fewer organic impurities" than milk. The catch, though, is that the vapor immediately gets mixed with the surrounding air. That means that there's always the chance that something funky gets mixed in with the air intake, especially if the Mirai's driving through a smog-infested city. That makes the idea of swigging off the tailpipe a slightly riskier venture, so it's best to keep that reusable bottle full of tap water handy. Toyota, which recently showed the Mirai off at the Los Angeles Auto Show, confirmed earlier this month that the Mirai would start sales in California in 2015 with lease rates starting at $499 a month. While the model's MSRP will be $57,500, federal and state incentives could bring that number to less than $45,000. Fewer than 200 Mirai vehicles will be available in the US by the end of next year.

Toyota unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

Toyota to boost its Subaru stake to more than 20%

TOKYO — Toyota Motor Corp plans to raise its stake in Subaru Corp to more than 20% from around 17% now, a deal that would also see the smaller firm invest in Japan's top automaker, two people with direct knowledge of the matter said on Friday. The deal is due to be approved at a Toyota board meeting on Friday, the people said, declining to be identified because the information has not been made public. The investment would come a month after Toyota and another smaller Japanese automaker, Suzuki, said they would take small equity stakes in each other. Such tie-ups highlight how automakers are scrambling to chase scale, manage costs and boost development. Traditional car makers, especially smaller ones like Subaru and Suzuki, are struggling to meet the fast pace of change in an industry being transformed by the rise of electric vehicles, ride hailing and autonomous driving. Toyota's investment is likely to cost more than 70 billion yen ($650 million) based on Subaru's stock market value, said the Nikkei business daily, which first reported the news. Subaru is likely to reciprocate with a stake in Toyota that would roughly equal the value of Toyota's additional investment, one of the people told Reuters. The companies have long worked together on projects such as the Toyota 86 and Subaru BRZ twins. At one time, Subaru built Toyota Camrys in its Indiana plant. Representatives for both Toyota and Subaru said the news was not something that had been announced by their companies. "The plan appears to be to ultimately make Subaru a fully owned subsidiary, to help create a 'mega Toyota.' This is the first step towards that," said Takeshi Miyao, managing director of Carnorama, a consultancy. "It's all about building scale." Subaru is particularly strong in sport-utility vehicles (SUV) and all-wheel-drive technology. The two automakers in June said they planned to jointly develop an electric sport-utility vehicle on a platform produced together, to split costs. Car markers around the world have been joining forces to slash development and manufacturing costs of new technology. Ford Motor Co and Volkswagen AG have said they will spend billions of dollars to jointly develop electric and self-driving vehicles. Toyota seems to be particularly keen to build scale now by investing in smaller, domestic automakers, rather than forging cross-border tie-ups like some of its rivals.
