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:

J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

Recharge Wrap-up: Honda Legend Sport Hybrid launching in Japan; driving cross-country on chicken fat

Honda will begin sales in Japan of the Legend Sport Hybrid SH-AWD in January. The Legend is Japan's answer to the Acura RLX Sport Hybrid sold in the US. Up front, the new flagship sedan uses a 3.5-liter V6 with cylinder deactivation and a seven-speed, dual-clutch transmission with integrated electric motor. In the rear, a dual electric motor unit supplies power to the wheels. The three electric motors are also used for generating electricity during deceleration. The car has three drive modes, including EV Drive, Hybrid Drive and Engine Drive. The result is a fuel economy rating of 40 mpg, according to the JC08 cycle.

While Jay Leno explains how marketing early electric cars toward women caused them to lose out to internal combustion, the same can't be said about the current era of EVs. Leno says that early EVs, like Leno's beloved Baker, appealed to women because they were quiet, clean, and didn't require cranking to start them. This led to accessorization marketed toward women, causing men - who had more buying power than women at the time - to shy away from EVs. This time around, though, EVs target a broader audience in a different culture from the early 20th century. See Leno explain the early EV culture while driving his Baker Electric in the video below and read more at Hybrid Cars. GKN's two-speed eAxle allows EVs to make the most of both acceleration and top speed. Single-speed transmissions must sacrifice top speed for acceleration, or vice versa. In addition to improving performance at all speeds and increasing range, the GKN's eAxle also performs well in terms of NVH, providing seamless shifts and low gear noise. In order to package the eAxle in the BMW i8, the unit is just 12.8 inches by 22.1 inches by 12.3 inches and weighs 60 pounds. Read more at Green Car Congress. An alternative fuels researcher at Middle Tennessee State University will drive a truck powered by chicken fat biodiesel across the country. Professor Cliff Ricketts is driving a converted 1981 Volkswagen Rabbit pickup from Key West, FL to Seattle, WA to demonstrate the viability of chicken fat as a fuel. Ricketts admits, though, that the truck's exhaust stack is loud and smells like French fries. Read more at Domestic Fuel. This content is hosted by a third party.
