Acura NSX GT3 racecar bares all in raw carbon

Acura slowly and dramatically revealed the NSX over a period of years. There were previews, concepts, and lots of teases before Acura finally showed us the whole thing. It's a different story for the racecar. And today, the wraps come off the FIA GT3-spec NSX to show all of its bare-carbon glory. The NSX GT3 strips away more than just the paint from the standard road car. The racecar comes sans hybrid system, meaning all the power from the twin-turbocharged 3.5-liter V6 is sent solely to the rear wheels. Modifications to the body include a large rear wing, underbody diffuser, and bigger hood vents for engine cooling. While the hybrid system may be gone, the NSX GT3 uses the same block, heads, valvetrain, crankshaft, pistons, and dry sump lubrication system as the road car. Power is sent through a six-speed sequential gearbox instead of the road car's nine-speed. The NSX GT3 will be built alongside the street version in Ohio. Honda engineers in Japan and North America shared in the development. Final GT3 homologation will be completed by the company's Honda Performance Division in Santa Clarita, CA. Related 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:

Acura touts full-line Top Safety Pick+ achievement in new ad

When a vehicle scores a Top Safety Pick+ in Insurance Institute for Highway Safety testing or a five-star rating from the National Highway Traffic Safety Administration, it's a darn big deal. But when an automaker's entire lineup earns the TSP+ honor and gets top marks from NHTSA it's a, um, well, it's never happened before. So congratulations, Acura. The premium Japanese brand is the first automaker to score top marks on the latest IIHS testing while also earning five-star NHTSA ratings across its entire range of vehicle. This, of course, is not the first time it's earned such a distinction – in 2009, and well before TSP+ existed, Acura was the first automaker to boast a lineup filled with TSP and five-star vehicles. With this new, five-vehicle lineup of TSP+ and five stars, Acura certainly has something worth crowing about. That's why it's preparing a new marketing campaign to crow about super-safe ILX sedans and MDX crossovers. Expect to see it on your TV starting on October 18. If you simply can't wait to see what Acura's up to, though, we've got a 60-second spot that features some very disturbing crash-test "dummies."
