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:

Average new-car fuel economy figures continue record pace

Manufacturers are making more efficient cars and trucks; we've known that to be true for some time. Nearly every new car has some sort of trick to eke a few extra miles out of every gallon of fuel. Whether that be turbocharging, active aerodynamics or hybrid technology/electrified powertrains, the fact is that our vehicles are more efficient than ever before.
Thanks to a recent study by TrueCar, we've got fresh quantitative data to support the above statements. For the fourth month in a row, we've seen an improvement in national fleet fuel economy. We Americans are 0.7 miles per gallon more efficient than we were last month, and our cars are 1.6-mpg better than at this time last year. That said, we're still down on 2013's high, which was set back in January at 24.5 mpg.
Not only does this reflect the improved technologies in our vehicles, but it demonstrates a changing mindset among consumers, who are purchasing more efficient vehicles despite the relative stabilization of fuel prices. Every fuel-efficient model sold drives its manufacturers fleet average up.

Is Fernando Alonso preparing to sit out 2016?

Things have not been going well for Fernando Alonso since moving to McLaren. In fact they've been going so poorly that the Spanish driver may end up sitting out next season if things don't improve. At least those are the rumors presently occupying the Formula One paddock. The notion was first raised by McLaren chief Ron Dennis. When asked by reporters about Alonso's near-term future with the team, Dennis said, "I have an open mind to anything, and some of the ideas have involved those sorts of considerations, yes, sabbatical years etcetera." Though far from confirmed, the basic idea would be to see how next year's car performs in pre-season testing, and if it's not up to spec, Alonso could end up sitting out a season while McLaren and Honda get their partnership up to speed, so to speak. Alonso appeared to be puzzled by the prospect his boss raised, but couldn't rule it out, either. It would be a rather unprecedented move, but could end up avoiding some frustrations as the Anglo-Japanese teething process works itself out with time. Alonso has been a constant on the grid since 2003, missing only two grands prix in thirteen seasons: the 2005 United States Grand Prix at Indianapolis when all the Michelin-equipped teams sat out the race in protest, and the Australian Grand Prix at the beginning of this year, when Alonso was still recovering from a crash in pre-season testing. Out of 254 grands prix contested to date, Fernando has landed on the podium 97 times, including 32 wins and two world championships. This season, however, he's only finished in the points once, with his fifth-place finish in Hungary. Of the eighteen races he contested this year, his car failed to get him to the finish line altogether at seven. His seventeenth place in the final standings for the season are the worst he's done since his debut in 2001 with Minardi (the team now known as Toro Rosso).
