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:

Racy, mysterious Honda spied in Spain

The next-gen Honda Civic five-door has been spotted near the IDIADA Proving Grounds in Spain, and Pistonudos was able to snap several photos of it covered in camouflage there. However, compared to the last spy shots we saw of this body, there have been some odd changes made for the latest test car. In front, the grille still wears a similar look to the pre-refresh Acura ILX like in the last photos. Although, this version might be a bit closer to production because as in the patent drawings, the air dam now sports three lower intakes. In profile, this Civic is largely the same as the earlier shots too, but now you get a better look at the tail's shape. The big, lightweight wheels and small brake discs are certainly odd on this example, though. The rear is where things get really strange because of the three exhaust pipes right in the middle of the bumper. Making things even weirder, the center one has a smaller diameter than the others. Because the Honda Civic Concept used a single, center-mounted setup, perhaps this is a way to test that design. Taken in total, this Civic test car is a head-scratcher. The bizarre exhaust layout and big wheels suggest a performance version, but the rest of the design doesn't look aggressive enough. One possible explanation is that Honda is testing a few components for the next Civic SI here. That would explain why some bits look racy but not the whole car. Related Video:

Honda unveils new 3.5-liter racing engine

Honda is following Ford's lead and debuting the second twin-turbocharged V6 to be used by Daytona Prototypes in the United Sports Car Championship. The wait won't be long to see it on track because the new engine will debut with the Starworks Motorsport team in a Riley Gen3 prototype chassis at the 12 Hours of Sebring from March 12-15.
The new HR35TT engine is based on Honda's J35 production V6 found in a variety of its models, including the current Accord. The racing version benefits from dry sump lubrication, but is still similar to the production version with an aluminum block, direct injection and single overhead camshafts. It is fueled by 100-octane E10 fuel, but like many racing engines, exact power figures have not been released.
Starworks has had a close relationship with Honda since it won the LMP2 class at the 24 Hours of Le Mans and in the FIA World Endurance Championship in 2012 with a Honda Performance Development ARX-03b chassis and Honda engine. We can't wait to see this new mill hit the track, and see how it fairs against Chip Ganassi Racing's EcoBoost-powered Riley. Scroll down to read the press release for the full details.
