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:

McLaren MP4-X concept shows innovation won't die in F1's future [w/video]

Despite things like turbocharging and kinetic-energy recovery, today's Formula One cars look more or less like the ones that lapped the world's race tracks 20 years ago. Sure, they're much more aero intensive, but the basic look is the same. McLaren, which probably had some serious free time this season considering its misfortunes, has imagined a futuristic F1 car that adopts many innovative and somewhat controversial additions. It's called the McLaren MP4-X, and the most obvious change is the closed cockpit. The death of Jules Bianchi, the accidents involving Maria De Villota and Felipe Massa, and even the death of Ayrton Senna could have all potentially been avoided by adopting a strong closed-cockpit design, like the one advocated here by McLaren. It's also worth pointing out that this design is a boon for aerodynamics. Inside that cockpit, drivers would enjoy an augmented reality display system, sort of like that used by F-35 Lightning II fighter pilots. There'd also be an independent head-up display that McLaren claims could be used to transmit info about race position and flag status. So basically, the kind of data you'd get playing Forza Motorsport or Gran Turismo. Speaking of safety, the MP4-X's entire chassis, beyond the closed roof, would be far safer thanks to the use of "negative-stiffness material structures." Essentially, these materials can soak up the force of an impact and then bounce, for lack of a better term, back into shape. And if you're thinking like we are, this sounds like McLaren wants 900-horsepower bumper cars. Of course, 900 hp is speculation on our end. McLaren is deliberately vague on the powertrain of this concept. Advanced hybrid powertrains aren't surprising, although the team's mention of inductive, wireless charging on tracks sounds like the stuff of Formula E's dreams. In a move that McLaren says "tears up the rulebook," the MP4-X would see a return of ground effects. The underbody would feature enormous venturi tunnels to suck the car to the track. Alongside active aerodynamics that tweak the its shape for turns and straights, this concept McLaren would be both more slippery and offer more downforce than today's cars. There's a lot more on the MP4-X concept than we can talk about here, so head over to McLaren Honda's official website for all the nitty gritty details on this car's advanced systems, including solar cells, advanced tire sensors, and even virtual logos. It all sounds very, very cool.

Car Club USA: CleanMPG Northwest Rally

Car Club USA heads to Los Angeles for the CleanMPG Northwest Rally, where a group of like-minded hypermiling enthusiasts led by Wayne Gerdes attempts to drive from Los Angeles, CA, to Bend, OR, on one tank of fuel. For this challenge, Wayne tapped some of the most accomplished hypermilers in the world, including Guinness World Record holder Bob Winger and Mike Sefton, "the most fuel efficient driver in all of Canada." It doesn't take long for the competition to get heated. "They're not aggressive enough, and it's not going to save them anything by being soft right now," says Gerdes as the group attempts to navigate the Interstate traffic. "Driving in Los Angeles is a hyper miler's nightmare," says Winger. The trip will challenge both car and driver, while putting the latest fuel-efficient tech to the test. Wayne is piloting the Volkswagen Golf Sportwagen TDI, Sefton drives the Audi A3 TDI, and Winger attempts the trek in a Honda Accord Hybrid. It's diesel versus hybrid tech on this fuel-efficient trip of a lifetime. Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.
