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 names new motorsport chief

Though it may have expanded into crossovers and sedans, Porsche is still a company with racing at its heart. You might even argue that Cayenne and Panamera sales only serve to fund the company's motorsports activities. Competition-spec 911 coupes still make up a large portion of the grid in any GT racing series, and those activities are presided over by the Porsche GT division (separate from its LMP1 program), which has just announced a changing of the guard.
Porsche's GT unit - which is responsible both for racing models like the 911 RSR and road-going models like the 911 GT3 - has until now been steered by Hartmut Kristen (pictured above, left) in his capacity as Vice President of Motorsport at Porsche AG. During his ten-year tenure, Kristen gave birth to the RS Spyder that competed in the American Le Mans Series and the pioneering 911 GT3 R Hybrid. He also fostered what Porsche characterizes as "arguably the most comprehensive youth development program in motor racing" and saw the marque return to Le Mans last year with a dominant 1-2 class victory.
Kristen, now 59 years old, is leaving the German automaker, but will remain an advisor to the company's R&D department. Taking over as VP of Motorsport will be Dr. Frank-Steffen Walliser, who has until now been head of the 918 Spyder project (a responsibility he will continue). Walliser (pictured above, right) was previously Porsche's general manager for motorsport strategies and will now be responsible for Porsche's GT projects on and off the track, while Fritz Enzinger continues at the helm of the LMP1 program in pursuit of better results next year than the 919 Hybrid achieved at Le Mans last month.

Despite premium carmakers going downmarket, luxury auto sales stick at 10-11%

According to research conducted by global information company IHS Automotive, the leporine birthing of new models by luxury manufacturers over the past six years hasn't increased their market share in the US. Even as car sales reached 15.6 million units, IHS says what's happened instead is that luxury buyers are merely moving from one brand to another, moving from larger luxury vehicles into hot segments like compact luxury crossovers or leaving the market at the same rate as other buyers enter.
Whether broken out by makes or by segment, market share has rollercoastered inside a narrow band from 10.5 to 11.5 percent since "at least" 2008. Closer investigation reveals the shifting boundaries in the aspirational pond, with brands like Mercedes-Benz and Audi gaining territory as Lexus and Lincoln lost it, and Saab and Hummer were buried, dead, under it. One neat note is that Tesla has gone from a share of zip to .12 percent.
The subcompact and compact crossover segments show growth, with those little high-riders jumping from .3 percent to 1.16 percent of overall industry sales. Their rise, though, is concomitant with the decline of four other segments: compact and midsize cars and fullsize cars and SUVs. We think the next few years that will tell if the small-car expansion can overcome the large-car retraction, with a phalanx of smaller offerings like the CLA only recently hitting the market and others like the GLA, Macan and Q1 doing so in the near future.
