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.

Porsche testing four-cylinder Boxster at the N?rburgring

Porsche recently introduced a four-cylinder version of the new Macan for markets outside of North America, carrying Zuffenhausen's first four-pot since the 968 ended its production run the better part of two decades ago. But you can bet the compact crossover won't be the only Porsche to get the four banger before all's said and done. These spy shots, we're told, are evidence of just that.
Spotted undergoing testing at the Nürburgring (where else), this modified Boxster, our spy photographers tell us, sounds more like a four-cylinder engine than the flat six that's powered (in displacements ranging from 2.5 liters to 3.4) every version of the little roadster since its introduction in 1996, the year after the last four-cylinder Porsche ended production.
The test mule is also wearing modified wheel arches and aerodynamic aids under the bumpers, front and rear. Just what they're doing there we're not sure, but we'll probably find out sooner or later.

Porsche recalls new 911 models over exhaust pipe issues

Porsche, though the National Highway Traffic Safety Administration, announced a voluntary recall on about 2,200 911 Carrera and Carrera 4 models built during the 2012 and 2013 model years. On cars equipped with the standard exhaust system it was found that the tailpipes could separate from the mufflers and become dangerous road debris; models that added the optional sport exhaust system are not included in this recall.
Affected vehicles were built between March and November of last year, but there have been no reports of the problem on any customer-owned vehicles. Porsche first noticed a cracked tailpipe weld on a test vehicle back in May, and since then has found similar problems on other internally owned vehicles, all with more than 25,000 miles on the clock. To fix the problem, dealers will be replacing the mufflers. Scroll down to read the official notice.
