2013 Audi RS5 Cabriolet

The Audi RS5 is a bit of an odd duck in the brand's US lineup. At the moment it is one of only two RS models - the other being the TT RS - atop a pyramid of A and higher-performing S models. It is not, however, the brand's flagship performance model - not even close - that space being occupied by variants of the R8 supercar, specifically the V10 and GT models, and upcoming 560-horsepower RS7.
The RS5 does, however, owe its beating heart to those ten-cylinder R8s, its own 4.2-liter V8 almost identical to those engines save for two fewer cylinders. Outside of the R8, then, the RS5 is the lone bastion of naturally aspirated V8 power in a brand that once happily shoved 4.2-liter V8s under any hood that they would fit. Today, not even the giant Q7 SUV offers a V8. Lastly, the RS5 is not new, except to us, having been on sale in Europe in coupe form the last couple of years.
While Europeans were able to enjoy the hardtop two-door without us, the RS5 Cabriolet is reaching both peoples around the same time: now. We reviewed the RS5 coupe just recently, and having spent some time with the tin-top model myself as well, here is my take on the droptop version of what I consider one of Audi's most interesting models.

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.

Dieselgate defeats Audi's Le Mans racing dynasty

Referring to what the automotive press has dubbed "Dieselgate", Audi's Chairman of the Board of Management Rupert Stadler announced that Audi is pulling out of the FIA World Endurance Championship by the end of the 2016 season. This means Audi will no longer compete in the 24 Hours of Le Mans. However, that doesn't mean Audi is through with competing on the world stage. Instead of fossil-fuel-powered prototype racing, Audi will now "focus on the things that will keep (it) competitive in the years ahead", namely Formula E. Having worked together previously with Audi tuner ABT and component manufacturer Schaeffler in Formula E, the company is now turning Team ABT Schaeffler Audi Sport into a fully factory-backed outfit. Audi's DTM efforts with the RS 5 DTM will remain untouched for the time being, and the company hasn't made a decision yet as to whether its World Rallycross Championship with the Audi S1 EKS RX quattro will continue. Audi has competed in Le Mans prototype racing for 18 years, during which it secured 13 Le Mans wins. Out of 185 races contested by Audi's LMP cars, they racked up an impressive 106 wins. Audi's victory in 2006 was the first with a TDI engine, and the first hybrid-engine win was claimed in 2012. From 2000 to 2008, Audi won nine consecutive American Le Mans Series titles.
