Toyota getting into 3D printing with i-Road in Tokyo

Think of it as Pimp My Ride for the Japanese green concept car set. Toyota is further publicizing its funky, really skinny, leaning i-Road electric concept vehicle by putting on a contest that, among other things, encourages folks to customize parts of the car's surface via 3D printing. Hey, it is a really small car. Toyota's Open Road Project in Tokyo, which will last about a year and will let about 100 participants work with 10 vehicles, also includes a component that lets contestants find the most creative parking spots by seeking out "small unused spaces with access to plug sockets" (we're sure Tokyo is full of them). What grabbed us, though, was the possibility of printing out panels for a three-wheeled car that's less than eight feet long and less than three feet wide. Earlier this year, we reported that Toyota would add five i-Road vehicles to a Tokyo carsharing pilot project. Toyota's unusual promotions for the admittedly unusual concept two-seater date back to early 2013, when the Japanese automaker featured a video of four i-Roads dancing their way through a sun-kissed Mediterranean village. Meantime, take a look at Toyota's press release below, and get more information on the project here.

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."

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
