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.

Production Porsche 918 Spyder images leak out of Chinese patent office

A few images of what looks to be the production Porsche 918 Spyder are here to say hello, courtesy of a patent office in China. If these provide an accurate look at what the hybrid supercar will look like, there are a few differences between it and the latest examples of the pre-production prototypes our spy shooters have seen.
The jerry-rigged turn signals inside the headlight enclosures and on the front fenders on the prototype are replaced with more polished units inside the headlamps located underneath the main beams. Behind that, the door handles have been swapped from horizontal latches on the door to vertical openings located just behind the door shutline.
We've also seen a Martini-liveried version of the 918 Spyder that has extra carbon elements that don't appear on this car. It was at the Nürburgring with carbon lips on the front fenders and another carbon element that hung from the rear fenders and ran down to the rear diffuser. When we saw the car on our Deep Dive piece, the front lips were gone but that rear piece remained, and we can't tell from the brochure and options sheet that we've seen so far what it comes with. The wheels from the concept and the green brake calipers, minus the polycarbonate covers, should be the standard fitment while the ten-spoke magnesium wheels will be a 29,750-euro (about $39,000 US) option.

2015 Porsche 911 Carrera GTS [UPDATE]

UPDATE: An earlier version of this story referenced the 911's six-speed manual transmission, but of course, Porsche uses a seven-speed manual in this car. The text has been changed to reflect this. There are no fewer than 19 different models in today's Porsche 911 series. While each appeals to the enthusiast, the race-bred GT3 is the pinnacle of the automaker's rear-engined lineup. Unfortunately, and despite the GT3's racing circuit prowess, its rigid track-tuned persona is too grating for many as a daily driver. To satisfy those who put sporty driving dynamics at the top of their list, but don't want to compromise comfort, Porsche has introduced the 2015 911 Carrera GTS. Raising its performance quotient, the GTS model boasts a handful of standard features that elevate it above its Carrera S siblings. Mechanically, it features an enhanced 3.8-liter flat-six bolted into the tail of the widebody platform (shared with the Carrera 4 and GT3). Other goodies include Porsche Torque Vectoring (PTV), Porsche Active Suspension Management (PASM), a black-tipped Sport exhaust system and centerlock 20-inch 911 Turbo S wheels (five-lug wheels are a no-cost option). Cosmetically, the GTS is differentiated by its darkened lights, painted black wheels, Sport Design front spoiler, Sport Design exterior mirrors, black engine grille, rear black louvers (or lights on all-wheel drive models) and a 'GTS' logo on the lower doors. Inside the cabin are standard Sport Plus seats, Alcantera upholstery throughout with contrasting stitching, black gauges and anodized black aluminum trim. Offering us an excellent opportunity to put the second-generation GTS through its paces on a variety of roads, Porsche tossed us the keys in the LA Basin and pointed us towards Willow Springs Raceway, in the Mojave Desert. Driving Notes The GTS is offered in coupe or Cabriolet body styles, each with a choice between rear- and all-wheel drive. Buyers are also offered a choice between a traditional seven-speed manual gearbox or Porsche's seven-speed dual clutch transmission (PDK). The GT3, meanwhile, is only offered as a coupe with PDK. We grabbed the keys to a Guards Red rear-wheel drive coupe with PDK for our outbound drive, and a GT Silver Metallic all-wheel drive Cabriolet with a seven-speed manual for our return trip. Finding another 30 horsepower from the naturally aspirated 3.8-liter flat-six required some old-fashioned tricks.
