Audi considering other variants, turbo V6 for R8

More details from the Audi R8 event at Spain's Ascari circuit have met the Internet, and they provide more intel on the supercoupe will evolve over the second generation. First, they note some small differences in stance with this new car, being wider than the current car and sitting 30 millimeters (1.18 inches) lower. Compared to its Lamborghini Huracan brother, it gets three extra centimeters in the wheelbase. Filling out the power numbers, the 'entry-level' V10 engine at launch rolls out 540 horsepower and 399 pound-feet of torque, does the 0-60 mile per hour dash in 3.5 seconds, and hits a top speed of 200 mph. The V10 Plus model rocks 620 hp and 412 lb-ft, which slices 0.3 seconds off that acceleration time and adds five more mph to the top speed. They'll transfer their power through a seven-speed S-tronic that shifts faster than before, and it will in turn send power through an electronically-controlled clutch at the front axle and a constantly variable limited-slip differential at the rear axle. The power split is said to default to 42/58 front-to-rear, but 100 percent of the torque can be sent fore or aft. Benchmarked against the 991-series Porsche 911, driving sensations travel through an electromechanical steering setup that can be had with a variable rack if preferred, leading to standard 19-inch wheels with the option of 20-inchers and tires developed specifically for this car. A Performance setting offers dry, wet, and snow modes; that first setting turns the ESC off except for situations of impending doom, and Audi racer and test driver Frank Stippler told Top Gear that understeer is reduced, to which TG added "it oversteers at will." Stippler said it's "a lot closer to the GT3 race car than ever before," and even though it's "a lot" less intense than the Huracan, it's just as fast on the track. His estimate is that the new R8 will lap the Nurburgring between ten and 15 seconds faster than the current car. R8 technical lead Roland Schala said the new chassis opens up new avenues of development because "there's no problem to change it," mentioning models like a Clubsport or Superleggera as no longer forbidden. Differentiation could come from a wider engine mix, too. Markets like China need smaller displacements, so Audi's twin-turbo V8 is expected to join the line-up at some point, bringing 500 horsepower.

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.

Audi, McLaren to bring winning cars back to Le Mans

Now gearing up for its 83rd running, the 24 Hours of Le Mans is as much about history as it is about racing forward. So this year, two key outfits in the event's history are celebrating by bringing back the cars with which they dominated in years past. Audi has been a force to be reckoned with and the team to beat at Le Mans in the modern era. It still may not have topped its sister brand and chief rival Porsche's record 16 wins, but Audi's 13 have all come in the past fifteen years since the turn of the millennium. That's one heck of a winning streak, which the German outfit will highlight by bringing every single one of its winning prototypes back to La Sarthe this year. From the R8 that kicked it all off in 2000 through the diesel R10 TDI to the R18 E-Tron Quattro that won last year. Ingolstadt won't be alone in racing down memory lane. McLaren announced it will be bringing back all five F1 GTRs that dominated the race in 1995. The quintet that finished first, third, fourth and thirteenth overall will lead a parade lap around the French circuit, joined by the new P1 GTR that will be making its dynamic debut as well as the customer examples of the special edition 650S Le Mans. What's more, winning drivers from '95 – Yannick Dalmas, Masanori Sekiya and JJ Lehto – will be on hand to participate in the parade lap as well, further highlighting the occasion.

Since 2000, the brand has won the race 13 times. This year, Audi has assembled all of its Le Mans winning models for a group photo for the first time. Every single one of them represents 'Vorsprung durch Technik.' The string of victories began with the Audi R8 in 2000. "Following a year of learning and gathering experience at Le Mans, we started the 2000 season with a completely new design," says Head of Audi Motorsport Dr. Wolfgang Ullrich.
