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.

McLaren boss' exclusive Porsche 935 Street is worth three 911 Turbos

McLarens may be exclusive, but there are still hundreds - if not thousands - of people out there who can say they own one. Mansour Ojjeh is one of them, but he doesn't just own a McLaren - he owns McLaren. As in, the company that makes the racing and exotic supercars. Or 25 percent of it, anyway. As the head of Techniques d'Avant Garde, Ojjeh is one of the British outfit's largest shareholders, previously having owned Heuer watches (before selling it to luxury giant LVMH) and engineered Porsche's most successful foray into Formula One - winning the world drivers' championship three times in a row and the constructors' title twice with Alain Prost and Niki Lauda behind the wheel of McLarens with Porsche engines developed and branded by TAG.
In short, he probably could get any McLaren he wanted at the drop of a hat, but also had strong ties to Porsche in the 80s, and this is the car he wanted. It's called the Porsche 935 Street, and it's the only one ever made. Inspired by the 935 racer that won Le Mans and over 120 other races, Ojjeh contracted Porsche Exclusive when it was still in its infancy to make him one for the road. So they took a 930 bodyshell, slotted in the 3.3-liter turbo flat-six from the 934 but cranked output up to 375 horsepower, and gave it the brakes, suspension, BBS wheels and wide-body aero from the 935 racer. They painted it a deep metallic red and trimmed the interior with cream leather and wood veneer.
When all was said and done, a total of 550 modifications were performed, detailed on a seventeen-page invoice and costing as much as three new 911 Turbos at the time. Ojjeh only put 12,000 miles on the odometer, running up and down the French Riviera, and has now put it up for sale at the upcoming Bonhams auction at Spa where it's tipped to fetch upwards of 300,000 euros - equivalent to $410k at today's rates, or, once again, the price of about three new 911 Turbos.

Which is quicker in the standing mile, a Subaru WRX STI or a Porsche Cayman?

The 2015 Subaru WRX STI and 2014 Porsche Cayman are both saddled with unfair reputations. The STI with its huge wing and gold wheels has the title of the ultimate boy-racer. On the other hand, Porsche brand snobs look down on he base Cayman as just a wannabe 911. In reality, they are both pretty fantastic performance cars. But what would happen if the two of them lined up at a stoplight, and maybe the guy in the suit in the Cayman started throwing some revs at the young man in the STI? Automobile decided to find out in a recent video pitting the two stereotyped hot rods against each other in a standing-mile drag race.
In terms of raw numbers, they are surprisingly close. Both use flat engines and six-speed manual transmissions here, but the Subaru has more power and torque. However, the Porsche makes up for it with 300 pounds less weight. Neither should have a problem with traction either thanks to the STI's sophisticated all-wheel-drive setup, and the Cayman's mid-engine, rear-wheel-drive layout.
The comparable specs certainly show themselves in the real world for the race. We're not going to give away the winner here because it's too exciting, but let's just say the finish is very, very close. Scroll down to watch both of them shrug off their stereotypes and show off their real performance.
