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 offering new tire option for Carrera GT

Let's face it: finding new tires for older cars can be challenging if tire manufacturers have stopped carrying the right sizes (this writer went through Hell to find a set of 205/60-13s). But what about tires for low-volume supercars, which use sizes that often won't fit on high-volume production vehicles? The Porsche Carrera GT isn't that old and tires are still available in the correct sizes, but the German automaker has shown its support of keeping them on the road by working with Michelin to give owners yet another tire option. Enter the Carrera GT-specific Pilot Super Sport.
It's common knowledge that tires are one of the most important pieces of the performance puzzle, and Porsche claims that the PSS tires, sized 265/35ZR-19 front and 335/30ZR-20 with Porsche's "N0" rating, will improve the Carrera GT's handling and stability all the way up to its claimed top speed of 205 miles per hour. That's important for a car with razor-sharp handling characteristics. They'll also net drivers a 10-percent increase in fuel economy on regular roads and up to 20 percent on racetracks, Porsche says.
The PSSs use cutting-edge tire technology to harness the Carrera GT's 610-horsepower. They have a dual-compound tread that's different from the inside of the tire to the outside, which, Porsche says, helps steering precision and increases maximum grip. Aramid fibers, which are lightweight but just as strong as steel, are used in the tire's belt to reduce unsprung weight.

Infiniti cribs new US boss from Porsche

Just weeks before he was supposed to become CEO of Porsche Cars Australia, Infiniti has apparently offered Porsche COO and Executive Vice President Michael Bartsch a deal he couldn't refuse. Thus, Bartsch has join the company as Vice President of Infiniti Americas, the luxury marque's top North American post. Bartsch replaces Ben Poore, who has been with the automaker since 2008, having led both a 22-percent sales surge in 2012 and the brand's current sales slough, Automotive News reports.
Bartsch, Porsche's No. 2 US executive, has held the COO and Executive Vice President positions at Porsche since 2005 and was scheduled to become CEO of Porsche's Oz division on September 1. Infiniti has experienced a number of recent personnel changes in the past week: it named Vincent Gillet, formerly an executive for Starwood Hotels & Resorts, to lead its marketing efforts worldwide and Simon Cox, a former designer for automakers including Ford and Peugeot, to head a new design studio in London.
Poore reportedly will pursue other interests outside of the auto industry. Read more about the personnel change in the press release below.
