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.

Porsche GT division rules out AWD, SUVs

Any German automaker worth its lap times needs a performance division. Mercedes has AMG, BMW has the M division, Audi has Quattro GmbH with its S and RS models... even Volkswagen has its R line of hot hatches. And though Porsche is a performance automaker unto itself, even it has a performance division. It's called Porsche GT, and though it's been branching outside the 911 range lately, don't expect it to wander too far. According to Car and Driver, which spoke recently with Porsche GT boss Andreas Preuninger and R&D chief Wolfgang Hatz, there are limits to what the division will do. And while those limits may have been broadened to include technologies like turbocharging and dual-clutch transmissions, they won't stretch as far as all-wheel drive. Take a look at the previous-generation 997 and what separated the 911 GT2 from the 911 Turbo was principally its all-wheel-drive system. Porsche GT isn't planning on doing a GT2 this time around – the new GT3 RS occupying that territory on its own – but the next generation (whether it wears the number 2 or 3) will likely go turbo along with most of the rest of the 911 family. The exclusion of all-wheel drive from the Porsche GT parts bin also means that the division won't be taking on the company's SUVs like the Cayenne and Macan. So the Cayenne GTS will be as extreme as it gets, taking on the likes of the BMW X5 M, Mercedes GL63 and Audi SQ5 without the help of Zuffenhausen's racing department. We can't expect the PDK to stick around though, so to speak. Though the new Cayman GT4 packs a manual transmission, the 911 GT3 and GT3 RS have dual-clutch gearboxes. Moving forward, Preuninger says they'll leave it up to prospective customers to decide which type of transmission they'll build into their most extreme performance models.

Porsche Pajun to go all-electric as Tesla rival

Porsche has been rumored to be working on a smaller counterpart to the Panamera for nearly four years now, but we have yet to see any sign of the model dubbed Pajun coming to fruition beyond a digital rendering hidden in the background of another Porsche design. Apparently Stuttgart has been having trouble making the business case in an already crowded market segment. But that doesn't mean the project is completely off the table. According to the latest from Germany's own Auto Motor und Sport, Porsche is now planning to launch the so-called Pajun (shorthand for Panamera Junior just like the Macan project was previously called Cajun) purely as an electric vehicle. With an eye evidently fixed on how dedicated hybrids and EVs are gaining traction in the marketplace (to say nothing of actual tarmac), the electric Pajun - almost certain to carry a different name to the showroom – would be different enough to distinguish itself from existing four-doors of that size like the Mercedes E-Class, BMW 5 Series, Audi A6, et al. Word has it that Porsche believes that battery technologies will advance enough over the next four years to give its four-door EV a range of nearly 250 miles on a single charge. The model's arrival would be just the latest in a series of environmental concessions made by the company with the broadest range of plug-in hybrids on the market. Aside from the E-Hybrid versions of the Panamera and Cayenne, Porsche arguably led the charge (so to speak) towards hybrid hypercars with the 918 Spyder, is downsizing many of its engines and is turbocharging almost the entirety of the 911 range.
