Race Recap: 2013 Petit Le Mans draws curtain on the ALMS [spoilers]

The 16th Petit Le Mans Powered By Mazda, in the final year of the American Le Mans Series presented by Tequila Patrón, was run on Saturday. Even though many of this year's championships had already been decided, the last ALMS race ever would be a 10-hour, 1,000-mile slog around Road Atlanta to get names in the record books and decide a few series trophies.
Since some of you will only get around to your TIVOs (or Fox Sports coverage) today, you should stop reading now if you don't want to know who did what...

Watch Porsche's 918 Spyder break a sweat while hot weather testing

With five months left until the 2015 Porsche 918 Spyder enters production, Porsche engineers are still putting the hybrid sports coupe through a battery of last-minute tests. To give us new reasons to ogle over the car - as if we needed any more - Porsche has released a short video showing the 918 Spyder undergoing shakedown tests in the hot Nevada desert. And you can't drive through Nevada without visiting Vegas, too, right?
Although there's really nothing new to see in this video, it's still fun to watch as Porsche approaches one million test miles logged on this exciting new high-performance model. One interesting part (at around the 0:37 mark) shows the car taking off under electric power and then transitioning to engine power, which results in a mix of whirs and growls as the 918 Spyder switches from a 127-horsepower electric vehicle to an 887-hp hybrid supercar. Scroll down to watch - and hear - Porsche's latest creation in motion.

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.
