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.

LaFerrari, McLaren P1, Porsche 918 and Agera R take to Assen

It's the show-down (sort of) we've all been waiting for. The battle of the hybrid hypercars from the performance powerhouses of Europe: Ferrari LaFerrari, McLaren P1 and Porsche 918 Spyder. No one publication has managed to get their hands on all three just yet, but this video has - and with a Koenigsegg Agera R thrown in for good measure.
The video was shot by our (unrelated) Dutch compatriots at Autoblog.nl at the TT Circuit Assen in the Netherlands. The track has played host to Champ Cars and all manner of racing bikes, but this could be the ultimate grid of actual production machinery that's ever lined up behind its start/finish line. Shame the weather was rainy and this unsurpassed array of supercars weren't really racing - more showing off for the crowds. But what a show it was. Scope out the footage in the video below.

Petrolicious details why the Porsche 911 is something special

The Porsche 911 is a special car, if for no other reasons than it's been continuously produced since 1964, with nearly every generation regarded as being at or near the top of its class. But why the rear-engined icon has done so well among enthusiasts and regular drivers alike can't always be explained easily. To truly understand the 911, you have to experience the whole package, and that means driving one.
While just about every publication has raved about the Porsche, commercial director, race driver, photographer and 911 owner Jeff Zwart explains to Petrolicious why he was drawn to the legend as a young child, and why he still loves them today.
Zwart's professional and personal life are inextricably linked to the 911, and hearing him talk about the car and its history makes for fascinating viewing. Watch the video below to hear Zwart's story and see him drive a couple examples from his collection: an early 911 and the 964-generation Carrera 4 he won Pikes Peak with for the first time - a car that happens to be equipped with the 959 Paris-Dakar's fascinating torque-split transmission. Enjoy!
