Porsche suspends 911 GT3 deliveries amidst fears of spontaneous combustion

Seeing pictures of Italian supercars burst into flames by the side of the road, as our compatriots at Axis of Oversteer point out, has become something of a usual sight. But a Porsche? Surely those meticulous German engineers have got that taken care of, right?
Not necessarily. Reports coming in from Europe indicate that no fewer than five 911 GT3 coupes have "spontaneously combusted" in the past few weeks, prompting Porsche to launch an investigation. In the meantime, they've reportedly ceased deliveries of the new GT3 while they try to determine what the problem is and work to rectify it.
We wouldn't be surprised to see a recall issued once the problem is resolved, but for now, we'd encourage existing owners to be extra vigilant behind the wheel - or better yet, leave their cars in the garage for the time being. You wouldn't want to drive a 475-horsepower rear-drive sports car through a Polar Vortex, anyway, right?

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.

'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.
