Porsche announces plan to replace 911 GT3 engines

About a month back, we reported that Porsche was suspending delivery of its 911 GT3 due to reported incidents of the engine bursting into flames. A few days later, Porsche told owners of the new track-ready models not to drive their cars and had their local dealers pick up the cars in question. Just a couple of days ago, we reported that Porsche was working on a fix, and now we have the official details.
Following an internal investigation prompted by two such incidents, Porsche has confirmed that is has identified the problem as resulting "from a loosened screw joint on the connecting rod." The loose connecting rod, Porsche found, damaged the crankcase, which in turn resulted in oil leaking and then - in at least two cases - igniting.
Our source is unaware of Porsche being contacted by GT3 owners concerned about the impact of a replacement engine on their car's collectibility or resale value.

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.

Porsche reveals new LMP1 racecar testing ahead of 2014 Le Mans debut

Getting ready for its triumphant return to the premier racing class of Le Mans, Porsche has released a handful of images showing its new LMP1 racecar testing. Porsche hasn't run a car in the Prototype class at 24 Hours of Le Mans since 2009, but this racecar - still veiled in secrecy - will be expected to battle against the Audi and Toyota LMP1 Prototypes to help bring Porsche its 17th Le Mans victory.
Aside from knowing that it will use a hybrid powertrain to meet LMP1 rules, there are no other details about the car... including its name or potential sponsors. In the meantime, Porsche has set up a microsite, called Mission 2014, to share its extensive history racing at Le Mans. Also, be sure to check out some of the past videos Porsche has released as it gears up for its reborn LMP1 program.
