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 finally moving ahead with flat four engine

When Porsche released the first Boxster in 1996 and the first Cayman in 2005, the idea was to create an entry-level model for the German automaker's sports car range. The latest iterations of both closely related models, however, have begun to encroach dangerously on the 911's territory, particularly in their newest GTS specifications. That could be about to change, however, with the introduction of a four-cylinder engine for the compact mid-engined coupe and roadster.
According to Automotive News, Porsche is finally preparing to launch a new boxer four engine in the Boxster and Cayman, following years of speculation. The engine would be based on the same architecture as the company's famous flat six, but with two fewer cylinders to cut weight. Don't expect it to cut much in the way of performance, however: Porsche chief Matthias Muller indicates that the new engine could produce as much as 395 horsepower - significantly more than even the 340hp flat six in the Cayman GTS, suggesting that the engine could even find its way into the 911 as well.
It's no more clear which markets would get the four-cylinder engine, either. But wherever it is offered and in whichever form, it wouldn't be the first time we'd see a Porsche with a four-pot engine. Not by a long shot. Both the classic 912 and 356 were powered by boxer fours, as was the 914 - not to mention the 718 pictured above and the iconic 550 Spyder. The front-engined 924, 944 and 968 packed inline-four engines, but the last of those were discontinued in the 1990s. The prospect of a four-cylinder Boxster/Cayman has been rumored for many years now, most recently joined by the possibility of a four-pot Macan as well.

Porsche LMP1 to use 4-cyl hybrid powertrain [w/poll]

With the Formula One season - and indeed his entire F1 career - now behind him, Mark Webber took advantage of his early release from Red Bull Racing to try out the new LMP1 which Porsche is developing, undertaking the final test session of 2013 before Porsche throws it head first into the FIA World Endurance Championship next April. The session - which followed previous tests at Magny-Cours, Monza, Paul Ricard and the Eurospeedway at Lausitz - was held at the Algarve circuit in Portimão, Portgual, in collaboration with Michelin, which is developing the tires for the car. But that's hardly the news here.
No, the news is the first confirmation we've seen on the type of powertrain Porsche has developed for its new Le Mans prototype: a gasoline-burning four-cylinder engine with direct injection and two energy recovery systems. This contrasts sharply with the V6 turbodiesel and single electric motor used by Audi in the R18 e-tron Quattro (or at least the outgoing version) or the naturally-aspirated V8 and single electric motor found in the Toyota TS030. Flexibility in the rules set down by the FIA and ACO give the manufacturers that kind of latitude, prompting F1 teams like Ferrari and Renault to consider developing their new engines for Le Mans prototypes as well.
At this point Porsche isn't saying how large its four-cylinder engine is or how much power it will produce. But it'll be interesting, to say the least, to see how it fares against the Audi and Toyota in next year's championship and at Le Mans when it'll be piloted by Webber, former Lola LMP1 driver Neel Jani and Audi's own 2011 Le Mans-winning pair of Romain Dumas and Timo Bernhard.
