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:

Honda speeds down memory lane with its first F1 car

Though most Formula One teams are based in the UK, they hail from places all around the world. There are teams from Russia, India and Malaysia, but in the 1960s, the idea of an F1 team coming from as far away as Japan was unthinkable in what was a predominantly European racing series. That's just the notion that Honda aimed to upset when it entered the car you see here in the 1964 Formula One World Championship.
With a 1.5-liter V12 dispensing 220 horsepower through a six-speed manual (its shifter necessitating the steering wheel mounted left-of-center), the 1964 Honda RA271 was built around an aluminum monocoque in a package that looks like a Formula Vee car you could erect in your garage, but it state-of-the-art when it was built. Speaking of which, Honda only built one, and today it's part of the Honda Collection Hall at Motegi, but the priceless racer made the trip down to Japan's capital so we could check it out at the Tokyo Motor Show. Awfully nice of Honda, we'd say. Check it out in our gallery of live shots from the show floor above.

Honda reveals three new turbo VTEC engines, including Civic Type R 2.0L

It's fair to say that in recent years, Honda has been viewed as a laggard when it comes to engine and gearbox development, seemingly missing the boat on direct-injection, forced-induction and high gear-count transmissions, among other things. But under its Earth Dreams banner, the Japanese automaker is showing new vigor, with the latest proof being this trio of just-announced powerplants.
Measuring 1.0-liters, 1.5-liters and 2.0-liters in displacement, this array of three- and four-cylinder engines boasts turbocharging and direct-injection along with the latest iteration of Honda's famed VTEC variable valve timing hardware. "Most suitable for small-to-medium-sized vehicles," the largest engine is said to be good for more than 276 horsepower and will slot into the eagerly awaited Civic Type R, iconic red valve cover and all.
Unfortunately, few other details about the hot Civic's engine or any of the others are being made public at this time, and there's no official word about the engines coming to North American in the Type R or any other model. Given that all the engines are complaint with stringent Euro 6 emissions standards, they figure to be clean enough, and Honda says that these have been developed as global powerplants, so we'd be shocked if they didn't come ashore in new or updated products over the next few years... even if they leave the CTR on the boat.
