24 Hours of Le Mans an on-and-off love affair

There was little usual about this year's 24 Hours of Le Mans - intermittent rain in the weeks before the race meant cars didn't get on track as much as they wanted, and intermittent rain during the race meant cars went off track a lot more than they wanted. The race started with a wet track, and one of the records broken because of the random downpours was the number of times the safety car led the field - 11 times this year - although the record of two hours and 53 minutes of lapping behind the safety car, set in 2011, was not eclipsed.
None of that served to dampen the action. With little more than an hour left in the race there were cars still only a few seconds apart fighting for position, leads still changing because of pit stops and everyone drafting anyone they could.
Things didn't go the usual way up front, either - well, not exactly...

Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.

Porsche rules out Macan, 911 hybrids

Believe it or not, between the 918 Spyder, the Cayenne and the Panamera, Porsche offers more plug-in hybrid models than any other brand. Yes, Porsche. But don't expect that trend to continue. At least, not in the immediate future.
According to Top Gear, the E-Hybrid powertrain in the Cayenne and Panamera is too big to fit into the smaller Macan. A future hybrid system could be small enough to fit, but with the current technology still fresh, that'd still be some ways down the twisting road.
It stands to reason, then, that if the system wouldn't fit in the Macan, it wouldn't fit in the Boxster or Cayman, either. But what of the 911? Surely Porsche would like to stick it to BMW and its new i8, and proved it could do a hybrid 911 when it rolled the GT3 R Hybrid (pictured) out onto the race track over four years ago. But Zuffenhausen is reportedly in no rush to put that idea into production - not for the current 911 and not for the next one, either.
