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:

Fernando Alonso expects to retire after McLaren-Honda

When Fernando Alonso was three years old, his father gave him a model of a McLaren-Honda grand prix car. That's where his path to Formula One started, and it's where he wants his career to end as well. Speaking with Autosport, the two-time world champion indicated that he intends to retire after he's done at McLaren, rather than switch to another team. Of course, he didn't indicate just when that would be, but as far as he's concerned, the road ends in Woking. The highly rated and immensely successful Spanish driver has been on the grid for fourteen years now. He started out with Minardi (precursor to Toro Rosso) in 2001, then spent four seasons with Renault, where he scored back-to-back world titles. He then switched to McLaren for one year, where he won four races, then back to Renault for another three where he and the team fell off their form. Fernando subsequently switched to Ferrari where he spent the last five seasons, thrice finishing second in the world championship but never quite managing to clinch an elusive third title. This year he's back at McLaren but has had a bumpy start. After crashing during a pre-season test session, he sat out the season opener, and failed to finish the second round in Malaysia. He's now in Shanghai preparing for this weekend's Chinese Grand Prix. Like this writer, he'll be turning 34 in July, making him the fourth oldest driver on the grid this year. So he's still got a good few years in him, and will likely want to see the troubled rekindling of the McLaren-Honda partnership through to winning form. But while nobody can tell what the future will bring, it looks like any other team that hopes to lure the champ away could end up disappointed.

Honda finds new Green Path to reduce CO2 emissions

In the wake of the Volkswagen diesel scandal, it's impossible to hear an automaker talk about its overall environmental efforts and not think to yourself, "for real?" Still, we're willing to listen. And Honda representatives gave it their best shot yesterday in Marysville, OH as they introduced a small group of journalist to the company's expanded initiative aimed at cutting CO2 emissions and the total life-cycle environmental impact of Honda products. Called Green Path, the initiative now includes a $210-million expansion at Honda's Marysville, OH manufacturing plant to install a better, cleaner paint shop. Speaking at the facility yesterday, Honda representatives said that the plant room is not only better for the environment (it uses limestone dust instead of water to capture paint particles, for example, reducing water usage by about 2 million gallons annually. Overall, the new paint shop will have 60 percent less VOC emissions and reduce CO2 emissions by 18 percent), it also makes the cars look better. That's whey the two-step temperature curing process will initially only be used on Acuras to differentiate them from the competition. Honda will fire up trials in late 2017. There's more to Green Path than the new paint show, of course. The company wants to reduce - in some cases eliminate - what it calls substances of concern (SOCs), things like lead and mercury. There are also new wind turbines in Ohio to supply power to Honda plants, the Environmental Leadership Program for independent dealerships to make their own green moves, and swapping out fluorescent light bulbs for LEDs, among other efforts. In the Marysville Auto Plant, for example, the Assembly department has over 10,000 task light bulbs. The fluorescent ones used to need to be replaced every three years, but the new LEDs have a life span of 16 years. Honda says that calculating up the impact of all of these little changes will remove an average of 3.822 kilograms of CO2 from the production tally of each car it makes. The company's stated goal is to reduce its total greenhouse gas emissions by 50 percent (compared to 2000 levels) by 2050. You can find out more in Honda's press release and video, below.
