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:

Vehicles awarded IIHS Top Safety Pick awards skyrockets for 2015 [w/video]

By practically every measure, passenger vehicles in the US are continuing to get safer. With the year rapidly coming to an end, the Insurance Institute for Highway Safety is releasing its annual list tallying of the scores for the latest vehicles to see how they compare to last year. Judging by the agency's evaluations, the numbers look quite positive. According to the institute, 71 vehicles earned either the Top Safety Pick or Top Safety Pick+ rating so far in its testing for 2015. Among the latest winners, there have been 33 TSP+ awards and 38 TSP medalists. That's a healthy increase over the 22 TSP+ and 17 TSP grades in 2014. The figures appear even more impressive when you consider that it keeps getting harder to earn the + designation. In the latest round of testing, a vehicle must offer some form of front crash prevention automatic braking to get the mark. Previously, just a warning to drivers was necessary. This list also illustrates the ways that automakers adapt to new testing procedures. In 2013 there were 117 TSP ratings and 13 TSP+ awards. Then, the IIHS mandated that to be a safety pick, a model had to score Good in the institute's four crash tests, plus a Good or Acceptable in the small overlap front test. That brought a plunge in 2014 to just 17 TSP grades. With the numbers climbing again, companies apparently have deciphered how to perform better. Some brands especially stood out on this year's list. The IIHS praised Volvo, Mercedes-Benz and Acura for offering standard front crash prevention systems on some models. Subaru received at least one of the awards for all seven of its models. Toyota also had seven, and the Honda brand did too – though the institute counts the two- and four-door versions of the Civic and Accord separately. Check out the full announcement below and a video about this year's winners. The full list can be viewed, here. Safety gains ground: More vehicles earn top honors from IIHS The number of vehicles earning either of the Institute's two awards has jumped to 71 from 39 this time last year, giving consumers more choices for optimum protection in crashes. The number of winners in the top tier - TOP SAFETY PICK+ - has increased by 11 for 2015, despite a tougher standard for front crash prevention. "This is the third year in a row that we are giving automakers a tougher challenge to meet," says IIHS President Adrian Lund.

Turbo Honda S2000 could battle Miata and 124 Abarth

Rumors are again swirling that Honda could have a new sports car under development to slot below the forthcoming NSX. Autocar claims the model would revive the S2000 name, but offer 1.5- and 2.0-liter turbocharged units at the front to drive the rear wheels. Autocar alleges this info comes from unnamed "company insiders," and asserts the new S2000 could have a base model with a 1.5-liter turbo that makes about 180 hp – almost 60 hp down from the original convertible. However, a hotter version – possibly with Type R badging – would reportedly have a detuned form of the 306-hp 2.0-liter in the Civic Type R. Both trims would have a six-speed manual. Competing rumors contend that Honda could be developing two different performance models. Patent images suggest the company might have a smaller version of the NSX under consideration in addition to the rumored S200 revival. The mid-engine coupe would allegedly use a hybrid powertrain based on the Civic Type R's engine to make a total of about 400 hp. However, Autocar claims the S2000 successor has the higher priority of the pair, but it doesn't mention where the info comes from. The Honda S660 kei car on sale in Japan shows that the brand is willing to dabble in new sports cars, but that convertible isn't practical for the US market, according to the automaker's bosses. Dealers meanwhile continue to beg a performance model in the lineup, so it's possible one of these rumored projects eventually could arrive in showrooms. Related Video:
