Engine problems stemming from two incidents of Porsche GT3 models burning in Switzerland and Italy has Porsche CEO Matthias Mueller possibly pulling back on the planned deliveries of the 2015 Porsche 911 GT3 RS. Apparently, Porsche wants to cover all its bases to ensure that the engine is working perfectly before committing to any launch dates.

Mueller made hints that the company is looking to delay the launch of the 911->ke282 GT3 RS in a conversation with Auto Motor und Sport. He didn't give out a specific date as to when the launch is going to happen, although he did make it clear that it won't happen until the company is sure that the engine has no more problems.

Mueller placed the blame on two screws coming loose in the engine as the reason for the fire, causing Porsche->ke1 to recall 785 911 GT3 models that are already in dealerships.

"The problem was, in the broadest sense, an engine problem," Mueller told Auto Motor und Sport.

"We now know why this happened, and now working out measures to prevent this in the future."

It's a smart move by Porsche, and one that it has every reason of doing. It'd be a shame if the 911 GT3 RS -- a car that's high in the wishlist of a lot of Porsche fans -- falls flat on its face when it hits the road.

The Porsche 911 GT3 RS is the perfect sports car->ke506 for those looking for true racetrack performance in a street car.

The RS version will be the next logical step after the new 911 GT3 is revealed sometime in 2013, and while the new standard GT3 will deliver somewhere in the neighborhood of 480 horsepower, the RS version reportedly carries at least 500 horsepower under its hood.

If that number has any validity to it, you can expect the 911 GT3 RS to be quick off the block, capable of hitting 60 mph in 3.2 or 3.3 seconds to go with a top speed of 196 mph.
