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.

Can a Corvette really be compared to a 911 with options costing more than the Chevy?

In this latest video from Drive, Chris Harris asks straight away, "Can you still compare a base Corvette to a Porsche Carerra?" That's an particularly interesting question in this film, as the 911 in question is a 400-horsepower Carrera S model that's been fitted with $60,000 in options. Base price of a Corvette Stingray? $51,995. Harris' tester features an automatic and some other goodies that push it right up to that $60,000 range. So yes, the options on the Porsche cost as much as this entire 460-hp Chevrolet.
Harris stresses that this isn't a full review, but he does exercise both cars in a more composed manner before reverting to his traditionally exuberant driving style. The impressions are, as always, spot on, with Harris favoring the pointy nature and V8 power of the Stingray, while enjoying the gearbox (Porsche's exceptional PDK transmission) and just about everything else on the 911.
Take a look below for the latest video from Drive, and let us know if you agree with Mr. Harris' views on these two sports cars.

Porsche 919 Hybrid revives Porsche's factory Le Mans efforts

After months of teasing with camouflaged testers, Porsche has finally unveiled its prototype entry for the 2014 World Endurance Championship, the 919 Hybrid. Porsche, you may recall, hasn't had campaigned a factory team at Le Mans in years, so the 919 is nothing less than their recommitment to endurance racing.
Combining a 2.0-liter V4 (yes, a V4) that revs to 9,000 rpm, the 919 produces around 500 horsepower with a pair of energy recovery systems. The first system recovers the heat energy from exhaust gasses as they pass through an electrical generator, while the second system is a bit more familiar. Using a setup similar to what is found on the production 918 Spyder, a generator on the front axle recovers kinetic energy from the brakes, which is subsequently stored in a battery system. That power can then be sent to the front wheels at the driver's command, effectively turning the 919 into an all-wheel-drive racecar.
Despite these various forms of motivation, Porsche doesn't claim to be seeking outright power supremacy, with Chairman Matthias Müller saying, "In 2014, it will not be the fastest car that wins the World Endurance Championship series and the 24 hours of Le Mans, rather it will be the car that goes the furthest with a defined amount of energy. And it is precisely this challenge that carmakers must overcome. The 919 Hybrid is our fastest mobile research laboratory and the most complex race car that Porsche has ever built."
