Green self-driving cars take center stage in Tokyo

Visions of cars that drive themselves without emitting a bit of pollution while entertaining passengers with online movies and social media are what's taking center stage at the Tokyo Motor Show. Japan, home to the world's top-selling automaker, has a younger generation disinterested in owning or driving cars. The show is about wooing them back. It's also about pushing an ambitious government-backed plan that paints Japan as a leader in automated driving technology. Reporters got a preview look at the exhibition Wednesday, ahead of its opening to the public Oct. 30. Nissan Motor Co. showed a concept vehicle loaded with laser scanners, a 360 degree camera setup, a radar and computer chips so the car can "think" to deliver autonomous driving. The Japanese automaker called it IDS, which stands for "intelligent driving system." Nissan, based in Yokohama, Japan, said it will offer some autonomous driving features by the end of next year in Japan. By 2018, it said vehicles with the technology will be able to conduct lane changes on highways. By 2020, such vehicles will be able to make their way through intersections on regular urban roads. Nissan officials said they were working hard to make the car smart enough to recognize the difference between a red traffic light and a tail light, learn how to turn on intersections where white lane indicators might be missing and anticipate from body language when a pedestrian might cross a street. Nissan's IDS vehicle is also electric, with a new battery that's more powerful than the one currently in the automaker's Leaf electric vehicle. Although production and sales plans were still undecided, it can travel a longer distance on a single charge and recharge more quickly. A major challenge for cars that drive themselves is winning social acceptance. They would have to share the roads with normal cars with drivers as well as with pedestrians, animals and unexpected objects. That's why some automakers at the show are packing the technology into what looks more like a golf cart or scooter than a car, such as Honda Motor Co.'s cubicle-like Wander Stand and Wander Walker scooter. Instead of trying to venture on freeways and other public roads, these are designed for controlled environments, restricted to shuttling people to pre-determined destinations. At a special section of the show, visitors can try out some of the so-called "smart mobility" devices such as Honda's seat on a single-wheel as well as small electric vehicles.

Honda builds up new Civic Type R ahead of Geneva debut

It's been a long time coming, but it's almost here. Or almost there, we should say, because it sadly won't be coming (at least in this form) to the United States. We're talking, of course, about the new Honda Civic Type R – a hot hatch we've been anticipating for about a year and a half now through a series of prototypes and concept cars. It's finally set to bow just weeks from now, in final production form, at the 2015 Geneva Motor Show. But before it does, Honda is giving us yet another taste of what to expect with a trio of teaser images and some juicy details. That Honda's new hot hatch would be powered by its new 2.0-liter turbo four we already knew, but now the Japanese automaker is telling us that it'll produce enough juice to propel the Euro-spec pocket rocket up to a top speed of 167 miles per hour. In a hatchback. That feat will be enabled in large part by its advanced aerodynamics, elements of which we can begin to see from the teaser images – including a big front splitter, deep side skirts, a giant rear wing and an almost completely flat underbody. It'll also be kept in check by a set of Brembo brakes with 13.8-inch drilled discs clamped by four-piston calipers up front and packed into a unique set of 19-inch alloys. It'll all be wrapped for the show stand in classic Japanese racing white, and we're even given a glimpse inside the cabin, where we can see red-glowing instruments, a red center marker at the top of the steering rim and that +R button we were promised. It's all shaping up to be a rather tempting package indeed, but will have to fend off the likes of the new Ford Focus RS and ever-improving challengers from the likes of Renault and Seat to dominate the European hot hatch scene. Hopefully we won't have to wait too long to see in what form Honda brings the fight to America, too.

Comma.ai makes your car semi-autonomous for $999

At TechCrunch's Disrupt conference in San Francisco, Comma.ai founder George "Geohot" Hotz announced the launch of the Comma One semi-autonomous driving device. Hotz said at the conference that his company has worked on the Comma One for about a year, and it will be available at the end of the year for $999 and a $24 per month subscription fee. But aside from the reasonable price, which TechCrunch points out is possible thanks to off-the-shelf components, the appeal here is that it's an add-on to an existing car that can be installed at home by the car's owner. This gives people with normal cars the opportunity to have semi-autonomous features without having to buy an entire vehicle... that is, if you have a Honda or Acura with lane-keeping assist, since Comma One is currently only compatible with those vehicles. It remains to be seen if the company will add more vehicles to the list over time. The device is roughly the size of a large cell phone or aftermarket navigation system, and it has a screen on the front and a pair of cameras on the back. The computer combines information from the device's cameras and the car's radar sensors to understand what's happening and how to respond. Hotz explained at the conference that this system is similar in capability to the Tesla Autopilot system, and will be able to complete a drive, start to finish, without the driver having to touch anything. He did however emphasize that the driver must still pay attention in the event something goes wrong, comparing the experience to watching a young student driver. Hotz told TechCrunch that the device should start shipping at the end of the year. He also said that owners of compatible Honda products in the San Francisco area are eligible for beta testing, and can get involved by emailing him at george@comma.ai. So if you've been pining for a semi-autonomous vehicle of your own, but couldn't spring for a Tesla, you won't have to wait much longer. We should point out that we don't know yet how well the system works, though we hope to find out soon. Related Video:
