Honda Performance Development reveals new ARX-04b LMP2 coupe

Make no mistake about it: Honda is big in racing. It was the first Japanese automaker to enter Formula One, remains the most successful and is set to return as an engine supplier next season. It's powered more IndyCar race winners and champions than any other manufacturer, hands down. Honda has won races and titles in Super GT, WTCC, even motorcycle racing. Just about everything this side of NASCAR, really. And that includes endurance sports car racing.
In fact Honda Performance Development prototypes claimed over 70 victories and numerous titles in the American Le Mans Series, and took the first LMP2 title in the FIA World Endurance Championship. And with sportscar racing in the US now grouped together into the United SportsCar Championship, Honda is back with a new chassis design.
Called the ARX-04b, it's Honda's first closed-cockpit LMP2. Like previous LMP2 and IndyCar projects, it's a joint development between HPD and Wirth Research, and packs Honda's HR28TT engine - a 2.8-liter twin-turbo V6 based on (and using many of the same components as) the J35 engine you'd find in a contemporary Acura. Designed to exceed the latest safety regulations, the ARX-04b features low-drag bodywork, quick-change front and rear panels, the same locking fuel filler system that Honda pioneered for Indy, top-exit exhaust to meet noise regulations, a 75-liter fuel tank and a gearbox that can easily be optimized for individual circuits.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum

Acura to roll out NSX Prototype for Mid-Ohio IndyCar race

Acura will tease us yet again with its next-gen NSX when it makes an appearance at Mid-Ohio Raceway before the circuit's IndyCar race early next month. To be fair, the car's in-motion debut won't take the form of a production model - that's still a ways off - the vehicle will be a prototype. It'll be sporting custom graphics and an eye-catching paint (wrap?) job to draw the attention of the spectators, but really, we just want to hear this thing rounding the legendary road course at full chat.
The NSX prototype doesn't look to be much different from the various showcars we've seen over the last couple of years, with the same mid-engined, hybrid V6 power and all-wheel drive all present and accounted for.
The display will take place before the Honda Indy 200 IndyCar Series on August 4. The race itself starts at 3:00 pm and will be shown on NBC Sports Network.
