2013 Porsche 911 RSR makes official debut

Porsche is ready to go racing in 2013, showing off a new 911 RSR today that is scheduled to compete in several endurance events this year. Based on the current 991 911, the new RSR will compete in the 2013 season of the World Endurance Championship and the 24 Hours of Le Mans. It will not, however, make an appearance in a North American racing series this year.
The 2013 version of the racecar has increased in wheelbase by some four inches, features a new wishbone front suspension in place of the last-generation's McPherson strut setup and boasts a new, lightweight six-speed racing gearbox. The engine, meanwhile, is an "optimized" version of last year's car, a 460-horsepower 4.0-liter boxer six-cylinder. Extensive use of carbon fiber and polycarbonate windows help the RSR shed weight, and Porsche has also balanced the weight more evenly with a lower center of gravity.
Porsche has thoughtfully dedicated some space to celebrate the 911's 50th Anniversary, with the number 50 clearly visible in the top-down view of the RSR, as well as along the doors. Scroll down to read the full Porsche press release, below.

Magnus Walker and Alex Ross stop by Leno's garage with their 997 GT2

The market is littered with Porsche 911 tuners, with names like 9ff, Gemballa and TechArt leading the field. Seldom do any two ever collaborate on a joint project, but that's just the kind of match that was made at Jay Leno's Garage. That's where Alex Ross of SharkWerks and restomodder Magnus Walker first met, sparking a collaboration that yielded the car you see here. And fittingly, they've brought it back to the garage to show off what resulted. Though Walker usually deals with older Elfens, this time he applied his eye for style on a more contemporary 2008 997 GT2, decking it out with grey stripes, orange bumpers, gold wheels and decals and a tartan-upholstered interior. He left the mechanical bits to Ross and company, who dropped the suspension and increased output to 650 horsepower at the wheels (775 at the crank), surpassing the stock GT2 and even the later GT2 RS. The result is pretty hard-core and old-school, but you'll want to watch the video above to see for yourself.

'Faster. Farther.' dives into the history of Porsche racing tech

No doubt, Porsche has produced some of the best endurance racecars around, such as the turbocharged, slant-nose 935 of the 1970s and the ground-effects-enhanced 956 and 962 of the 1980s. But the company's most famous racecar, its first overall winner at the 24 Hours of Le Mans, was the 917.
The 917 embodied many of Porsche's technological achievements up to that point, such as the company's first 12- and 16-cylinder engines (the flat-16 was never used in competition), fiberglass bodies that implemented early aerodynamic practices and the use of new, exotic materials, such as magnesium and titanium.
The racecar was commissioned by the head of Porsche Motorsports, Ferdinand Piëch, to win overall at the 24 Hours of Le Mans in 1970, after he realized a loophole in the rules that allowed cars to compete with engines up to five liters in the Sport category if they were also production models. Piëch saw opportunity: the top prototype class was restricted to three liters; the production minimum to compete in Sport was 25 cars. And so, with much effort, Porsche assembled 25 "production" 4.5-liter 917s and had them parked in a neat line for the race inspectors to verify their legitimacy. It didn't take long before people realized the new Porsches were much faster than the prototype racers, with a top speed approaching 250 miles per hour.
