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.

2022 Lexus IS 500 F Sport Performance brings back the V8

The 2022 Lexus IS 500 F Sport Performance revives the dormant IS F formula, bringing V8 power back to the compact luxury Japanese sport sedan for the first time since 2014 and confirming rumors of a new series of V8-powered performance (small p) cars from Lexus. Very little surprises us these days, especially in the luxury segment, but if you'd told us a month ago that we'd be confirming a V8-powered Lexus IS and a new, all-four-cylinder lineup for the Mercedes-Benz C-Class in the same week, we'd have called you crazy. Parent company Toyota's presence in Texas may have rubbed off on Lexus, though, because after a years-long hiatus, the V8-powered IS sedan returns. That's right. A V8. In a brand-new compact sport sedan. In 2021.  The new sport sedan will pack a 472-horsepower, 5.0-liter V8 with 395 pound-feet of torque, making it the spiritual successor to the discontinued Lexus IS F. For those keeping track at home, yes, that's the same V8 Lexus has utilized elsewhere in recent years. It currently powers the RC F coupe and, until last year, was also found under the hood of the larger GS F sedan. Like the BMW M3 it matches for power, the Lexus will come standard with rear-wheel drive and a limited-slip differential, making it a true performance machine. Power will go to the rear end by way of the same eight-speed automatic Lexus uses elsewhere as well. Sorry, folks, there's no stick, but hey, the IS F didn't have one either, so let's not get too picky. The original IS F also offered just 416 horsepower and 371 lb.-ft. of torque, so remember, this is all upside here. The original also launched without the LSD, if you'll remember; that came later.  2022 Lexus IS 500 F Sport Performance View 26 Photos The other significant edge the IS 500 F Sport Performance will have over its two-generations-removed predecessor will be the benefit of almost a decade's worth of interior development. While the IS platform was not significantly overhauled for the 2021 "re-imagining" (as Lexus puts it; we prefer the term "remodel"), the interior was, and the IS 500 F Sport Performance will benefit from all of the base sedan's upgrades, including a thoroughly overhauled infotainment system, which is night-and-day better than what was offered previously.

Toyota aims to build autonomous car around 2020 [w/videos]

The race is on to get increasingly sophisticated forms of autonomous driving technology on the road, and brands like Tesla are bringing these solutions to some drivers now. But as one of the world's largest automakers, it's no surprise to see Toyota competing in the field, as well. By 2020, the company thinks a person could be largely unnecessary for freeway trips. With a suite of tech called the Highway Teammate, a modified Lexus GS is already showing what's possible. Using a combination of millimeter wave radar, LIDAR, and cameras, the GS gets a full view of the road, and software processes all of the info to make decisions. The result is a ride on the freeway without human interaction. The system can merge, change lanes, make passes, take curves, and maintain a safe distance from other vehicles. Accurate map data is a necessity to make this work, so the system currently only being tested on Tokyo's Shuto Expressway. While Highway Teammate might not be the best name, it accurately communicates the way Toyota thinks of the tech. The company is making big investments in artificial intelligence to assist drivers, not completely replace them. You can see the system in action in the video below, and the second clip's gravely serious narrator explains the company's idea of having a fully connected road someday.

New Toyota Test Vehicle Paves the Way for Commercialization of Automated Highway Driving Technologies Toyota City, Japan, October 6, 2015-Toyota has been testing a new automated driving test vehicle called Highway Teammate, with the aim of launching related products by around 2020. In addition to demonstrating the capabilities of next-generation safety technologies, the vehicle represents Toyota's view of the evolving driver-car relationship in the age of artificial intelligence. Toyota believes that interactions between drivers and cars should mirror those between close friends who share a common purpose, sometimes watching over each other and sometimes helping each other out. Toyota refers to this approach as the Mobility Teammate Concept, and Highway Teammate represents an important first effort to give form to this concept.
