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?
