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-Piech buy 10% stake in VW's holding company

In August, 2009, as the scuttled merger of Porsche and Volkswagen had gone bad and Porsche was backed up against the ropes, Porsche Automobil Holding SE (PAHSE) relinquished a ten-percent stake in itself to Qatar Holdings as well as options it held on 17 percent of VW shares. The sale meant that, for the first time since the founding of the company 61 years before, an entity outside the Porsche and Piech families had a say in the running of PAHSE.
Buying that ten-percent stake back returns full ownership to the two families, the holding company's sole possession being ownership of 50.7 percent of VW's common shares. The price paid wasn't disclosed, but at market rates the purchase would be worth close to $1.25 billion. Qatar intends to hold onto the 17-percent stake it has in Volkswagen.

Porsche kicks off Macan production at revamped Leipzig plant

After over two years of construction and roughly 500 million euros ($684 million at current rates) invested, Porsche finally opened its Leipzig, Germany, factory expansion on February 11. The improvements to the plant are dedicated to building the Macan and include a new body shop, paint shop and assembly line that are advancing Porsche's goal to sell 50,000 Macan's per year. The company believes that the new model is going to push it to over 200,000 annual sales 3 years ahead of schedule, and the enlarged branch can support even more Macan production, if there is demand.
"We are totally convinced in the qualities of this location and that the Macan will be a marketing success," said Porsche Chairman Matthias Müller during the opening celebration. The company opened its Leipzig factory in 2002 to build the Cayenne and added Panamera production in 2009.
The Macan models are due to launch in the US this summer with prices starting at $49,900. Scroll down to learn all of the details about the Macan's Leipzig assembly plant.
