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.

Watch MotorWeek review the last great air-cooled Porsche 911

These days air-cooled Porsche prices are blasting through the roof, and the 993 gets much of that love among collectors as the last generation before the 911's switch to water-cooled design. MotorWeek's latest Retro Review now looks back at the 1996 911 Targa. The coupe came from a brief period when the 911s were the only models in the brand's lineup, but the company made sure those cars were perfect. The point of Porsche's Targa models is to combine the open-air driving of a convertible with a security of a coupe. In this case, the engineers came up with a massive glass panel that slid into the roof at the touch of a button. The design still allowed for rearward visibility but created a giant opening to allow the sunshine in. The solution isn't as awe-inspiring to watch as the Transformer-like metamorphosis of the latest 911 Targa, but it gets the job done in a very unobtrusive way. As air-cooled values continue to creep upward, it's fascinating to hear how contemporary reviewers critique the cars. In this case, the 993 lives up to the promise of being the ultimate evolution of the original idea behind the 911. MotorWeek even calls the coupe "simply one of the best road cars ever made." Check out the video to find out why. Related Video:
