Audi commits two R18 E-Tron Quattros to final Sebring race for LMP1 cars

We were baffled a few weeks back when the American Le Mans Series and Grand-Am Rolex Sports Car Series announced new classes that will make up their combined racing program in 2014. Gone from the list is the Le Mans Prototype class, otherwise known as LMP1. The LMP1 class has long been the top dog of endurance racing, both in Europe and the US, so we couldn't figure out why this newly minted racing series was jettisoning it like yesterday's donuts.
It appears as if Audi is confused by the move as well. The German brand has announced it will participate in this year's ALMS opening round, the famed 12 Hours of Sebring, as it does every year, and bringing two Audi R18 E-Tron Quattro hybrid race cars with which to compete. Unlike every other year, Audi is treating this year's race as its potential swan song in this famous Florida race.
There's a good reason that Audi is so fond of the 12 Hours of Sebring, as it debuted the gas-powered R8R there in 1999 that kicked off its participation in the upper echelon of endurance racing. The R8R preceded the R8, which debuted at Sebring in 2000 and won that race, starting an amazing career for that car that included five more wins at Sebring. The R8 was followed by the R10, then the R15 and R18, and finally we wind up at today's R18 E-Tron Quattro - all winners, all dominant, all exciting to watch.

For Audi, Quattro name means something for hydrogen cars, too

Forget Dueling Banjos. Audi is proposing "Dueling Motors" for its Audi A7 Sportback H-Tron Quattro concept vehicle. All in the name of appropriate pickup, of course. The German automaker, which showed off the concept sedan at the Los Angeles Auto Show last month, is pairing a plug-in electric motor with a hydrogen fuel cell powertrain. Each motor powers two wheels, maintaining the Quattro's all-wheel-drive pedigree. The car's 8.8-kWh lithium-ion battery can drive the car as far as 31 miles on battery-power alone. After that, the water-vapor-spewing fuel-cell engine kicks in. Audi executive Ulrich Hackenberg told Automotive News Europe that the unusual set-up is necessary because the hydrogen fuel cell powertrain alone would only power two wheels while providing an insufficient 136 horsepower. Not exactly sport-sedan material, especially for a car that weighs about 4,300 pounds, even if it is a zero-emission ride. Combined, the two engines give the sedan 231 horsepower as well as a combined single-charge/full-tank range of almost 350 miles. What it all means is that the A7 can go from 0 to 60 miles per hour in less than eight seconds and has a top speed of about 112 miles per hour, and can still dash through the snow.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.
