2016 Acura NSX grows into its updated styling for the 2015 Detroit Auto Show [w/videos]

It's not immediately clear at first glance, but the Acura NSX as it appears on the floor at the 2015 Detroit Auto Show is a far cry from the concept from the 2013 show. These days, the NSX packs a twin-turbo, longitudinally mounted V6 with over 550 horsepower on tap and nine-speed dual-clutch gearbox. Although, the three-motor hybrid setup remains with two units at the front and one for the rear axle. The numerous slashes and scoops make the design look much more aggressive than the earlier concept, but the changes go much deeper than the new skin. There's an inch of extra width and 3.1-inches more overall, including 0.8-inches extra length in the wheelbase. Underneath it all, is a carbon fiber floor and aluminum-intensive chassis to provide strength to harness all of its power. Unfortunately, Acura isn't specifically announcing engine output, the weight or the design's drag coefficienct yet, so there are still questions to answer. However production starts in fall 2015 with the order books opening in the summer. Pricing is among the factors that the Japanese brand isn't discussing, but it likely costs about $150,000 to park the company's latest supercar in your driveway. In the meantime, enjoy admiring this upcoming entry in the hybrid supercar market. Related Video:

Ford driving Alaskan maniac rams toddler-carrying SUV

A couple from Anchorage had a frightening traffic encounter when they were followed and repeatedly rammed by a stranger in a pickup truck. Grace Bernert, her boyfriend, and his two-year-old daughter were returning home from a trip to downtown Anchorage when they noticed a blue, 2001 Ford F-150 following closely behind them. "The guy was so close, we couldn't see his headlights," Bernert told KTVA. Bernert, who was riding shotgun, pulled out her phone to record the truck when it struck the rear end of their Acura SUV. That's when she called 911. Bernert's boyfriend tried to lose the F-150 in the Sullivan Arena parking lot, then drove to a local Ford dealer's parking lot where he drove through a maze of new Ford pickups in an attempt to shake their assailant. "We started doing circles around the brand new Fords because we thought the truck wouldn't be able to turn as fast as we would," said Bernert. "We were right, but the guy didn't care. He just kept hitting the new fords and backing up, coming after us." The truck continued to follow them, ramming the Acura again and again. Bernert estimates that F-150 driver struck their SUV between five and seven times, and hit numerous new trucks in the dealership parking lot. Eventually, they ducked into a nearby neighborhood where they managed to lose the F-150 and called 911. Bernert told KTVA that she believes they were targeted but doesn't know why. "The guy was either some random sick person who didn't care, or somebody who knew us and didn't care there was a kid in the car," she said. Anchorage Police arrived shortly after the couple escaped the F-150 and filed a report about the incident. They are currently investigating. Recent Video:

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:
