Audi races ahead with new R8 LMS [w/video]

The biggest news from Audi at the Geneva Motor Show may very well be the reveal of the all-new, second-generation R8 supercar. But the road-going version isn't the only one it's rolling out at the Swiss expo, where it's joined by the new competition-spec R8 LMS. Set to hit race tracks around the world next season, the new Audi R8 LMS picks up where the current one leaves off, having taken 26 GT3 Championship victories and seven 24-hour race wins between 2009 and 2014. That's a heck of a mantle to assume, but the new model looks like it'll be up to the task. Based on the new road-going R8, the new LMS is built to 2016 GT3 regulations and in many ways even exceeds them. In fact, Audi says it meets the more stringent crash requirements for the LMP1 class, and includes its state-of-the-art Audi Protection Seat PS 1 from the R18 E-Tron Quattro. It also incorporates the emergency hatch Audi built in to its DTM racers. Of course, there's more to the new R8 LMS than safety. Despite the addition of those features, the whole package is a good 55 pounds lighter than the outgoing model, thanks to the lightweight spaceframe chassis and the increased use of carbon-fiber components – all the while offering more torsional rigidity. Power still comes from Audi's celebrated 5.2-liter V10 engine producing 585 horsepower, but is now mated to a new six-speed sequential gearbox and benefits from an entirely new electrical system, improved airflow and optimized aerodynamics. All that and more ought to help the new R8 LMS and its customer racing teams achieve the success they're after once it makes its competitive debut at the Nurburgring 24-hour race in mid-May 2016.

The new Audi R8 LMS is lighter and safer than ever before. It features even more race car technology, clearly improved aerodynamics and, as a result, provides customers with an efficient concept. Back in spring of 2014, Audi began testing the new R8 LMS that is following in big footsteps.

Audi R8 V10 Plus takes on Ducati Diavel in straight line

The classic car-versus-motorcycle comparison is put to the test as Autocar pits a 2013 Audi R8 V10 against the Ducati Diavel in a run from 0-150-0 miles per hour. While you might expect the 162-horsepower Ducati weighing just 515 pounds to blow away the 542-horse, 3,500-pound Audi, this particular test measures the acceleration and braking of both high-performance machines.
Drag racing an Audi R8 against a Ducati on a long, flat stretch of concrete sounds fun to us, and Autocar documented the whole test for our viewing pleasure. We don't want to spoil the fun for you, so let's just say that a Volkswagen-owned brand wins. Scroll down to watch the video for yourself.
