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.

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's new twin-turbo V8 will power Audis

Porsche unveiled a new twin-turbo V8 engine at the 37th International Vienna Motor Symposium yesterday. According to a report from Car and Driver, the engine will see use in future V8 applications across the VW Group and could find its way into various Audis, Bentleys, and even the Lamborghini Urus. We expect to see it first in the 2017 Porsche Panamera. The engine makes 549 horsepower and 567 pound-feet of torque, or 21 hp less than the 4.8-liter twin-turbo V8 in the Panamera Turbo S. Welcome to the brave new world in which Porsche is a more-integrated part of the VW group. While the new engine puts out impressive numbers, it likely means that the Porsche-exclusive 4.8-liter is headed for the history books. Component sharing is nothing new - Porsche already uses other VW Group engines in its lineup - but it means the flat-four and flat-six engines in the 718 Boxster/Cayman and 911 will be the only unique powerplants remaining in the Stuttgart automaker's offerings. According to C/D, the new engine features cylinder deactivation and is optimized for future hybrid applications. It also consumes 30 percent less fuel than its predecessor, and will mate to both an 8-speed automatic and ZF's dual-clutch 8-speed. Along with the next Panamera, Porsche is also likely to use this engine in the Cayenne. A representative of Porsche North America was unable to provide any official information to Autoblog.
