Porsche has apparently released the first photos of the 2014 911 GT3 RSR, ahead of its racing debut at the World Endurance Championship season-opener in Silverstone on April 14th.

Based on the new 911 (codename 991), the GT3 RSR prototype was recently tested at the Sebring International Raceway by Porsche works drivers Richard Lietz (Austria) and Patrick Pilet (France). Both men will compete in the World Endurance Championship along with Marc Lieb (Germany) and Joerg Bergmeister (Germany).

According to Porsche’s Head of Motorsport, Hartmut Kristen, “We are very pleased with how the testing has gone so far. Our goal is to be well prepared for the challenges of the very strong GTE class in the WEC and at Le Mans." Kristen went on to say "Until the season kicks off in Silverstone, we will conduct some final tests on other race tracks so that our new 911 RSR is well and truly ready for the World Endurance Championship season.”

Porsche hasn't released any technical specifications, but the prototype features an aerodynamic body kit with modified bumpers, a ventilated hood, revised side skirts and a prominent rear wing. There's no word on what will power the car, but the outgoing model has a 4.0-liter boxer engine with 460 HP (338 kW).
