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 offers design walkthrough of Panamera Sport Turismo

The Porsche Panamera Sport Turismo was arguably the best concept car of 2012, and Porsche has been building upon that momentum by teasing us with videos of its first-ever station wagon design. After showing us some driving shots of the Sport Turismo, Porsche released a more in-depth and behind-the-scenes look at what it took to take the Panamera shooting brake from a full-scale clay model to the final product we saw on stage at the Paris Motor Show. In the video, Michael Mauer, Porsche style director, and Mitja Borkert, general manager advanced design style, both give a little insight about what went into creating the Sport Turismo Concept.
More than just a station wagon version of the Panamera, the Sport Turismo has a totally distinctive look nose to tail. Some of the key elements the designers touch on in the video include the Porsche-signature raised front fenders, the wide rear shoulders, the front wing inspired by the 918 Spyder, and even some of the car's unique touches, including the headlights and the three-dimensional "Porsche" lettering across the liftgate made from glass. One of the more exciting aspects of the concept - which is sadly just glossed over in the video - is the rear liftgate spoiler that features "variable aerodynamics" that sounds like it acts similar to the retractable spoiler on the current Panamera.
We still don't know if the Panamera Sport Turismo will make it into production, but if you want to see what went into creating this exciting concept car and see the different build phases designers went through to create the Paris show car, check out the video by scrolling below.

Porsche patent sketches show removable headrest wind deflector

While driving around in a convertible might seem glamorous, ask anyone with long hair and they'll likely tell you how it really is: the wind buffets, your hair goes everywhere and it's anything but glamorous. That's why you see so many convertibles driving with their tops up, their windows up or wind deflectors in place. But Porsche is apparently preparing to kick it up to the next level.
These patent drawings have leaked out, demonstrating what appears to be some new kind of wind-deflecting device being developed by Porsche. The mechanism is apparently fitted to the headrest itself and designed to keep the wind buffeting specifically around the head down to a minimum while allowing the car's occupants to enjoy the top-down driving experience.
No word on when it might hit the market, but we won't be surprised to see this kind of device appear on a future version of the Boxster or 911 Cabriolet. But nowhere else: despite the apparent leak, the patent drawings suggest that Porsche will be keeping this technology proprietary. Whether sister brands like Volkswagen, Bentley or Lamborghini will get their hands on it remains to be seen.
