NHTSA closes probe into 2011 Porsche 911 coolant leaks

The National Highway Traffic Safety Administration has announced that it will end its investigation into rapid coolant loss in 24,635 Porsche 911s built between 2001 and 2011. The models affected included the standard 911, GT2, GT3 and Turbo, as well as their variants (GT2 RS, GT3 RS and Turbo S).
NHTSA was investigating for "rapid coolant loss caused by coolant pipe-fitting failure, allegedly resulting in vehicle disablement and/or loss of vehicle control due to reduced traction for the affected vehicle or following traffic," according to the regulators website. "Most of the leak complaints did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked," said NHTSA's statement.
There were 63 complaints and 336 warranty claims, although the investigation was initiated after ten complaints from customers. There have been no reports of crashes or injuries attributed to rapid coolant loss.

'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.
