Ex-F1 driver Mark Webber has tough life, shakes down Porsche 911 GT3 RS

It's good work if you can get it, and Mark Webber has got it. The works driver for the Porsche World Endurance Championship Team was apparently asked to moonlight in a video shoot for the company's new 911 GT3 RS at the Nurburgring Nordschleife, and what do you know, he complied. They don't appear to be going too quickly, and a racing driver asked to rein in what will be one of the most blistering cars we'll see this year must be very serious work, because Webber doesn't appear to be smiling at all. We'll guess there's a big smile on the inside, though, and some tales to tell to his Porsche teammates at the next WEC race. Maybe the next time we see the 911 GT3 RS at the 'Ring, it will be doing the timed lap we're all waiting for. Related Video:

Porsche Cayman GT4 looks sexy, rapid in the nude

Porsche doesn't officially have a name for its more hardcore version of the Cayman, yet. The speculation is that the coupe is called the GT4 as a little brother to the 911 GT3. However, the German sports car maker apparently is not interested in keeping the model's looks much of a secret because these latest shots show it without a hint of camouflage to speak of. The GT4 reportedly takes the GT3's ethos of more power, less weight and stickier-than-glue handling and brings it all to the Cayman. As these photos show, there's a much lower air dam up front with a cooling vent at the tip of the hood. Larger wheels are another obvious addition and are likely shod with some very sticky rubber. At the back, there's a double spoiler combining a wing and a ducktail. The power and gearbox for the GT4 remains a mystery, though. The rumor is that it uses a tuned version of the 3.4-liter flat-six in the Cayman S and GTS to make between 370 and 400 horsepower. A similar overhaul of the Boxster might be on the way, as well. A version of the convertible wearing some of the Cayman GT4's goodies was recently spotted testing. That one even had a manual transmission to make the prospects behind the wheel even more exciting.

Volkswagen reportedly to name Matthias Muller CEO

Porsche chief executive officer Matthias Muller is expected to be named CEO of Volkswagen AG, the Wall Street Journal and other sources reported Thursday morning. Muller, 62, has led Porsche since Oct. 1, 2010, and jumpstarted the sports-car brand's expansion around the world. He replaces Martin Winkerkorn, who stepped down Wednesday amid the company's worsening diesel scandal. At least three more executives are also expected to be fired, including Volkswagen's US chief and the heads of Audi and Porsche research and development. Both brands are divisions of VW. A US spokesman wouldn't confirm the reports. An official announcement is expected at VW's board meeting on Friday. Muller's ascension caps a stunning week of turmoil for Volkswagen, which manipulated software to make its diesel-powered vehicles appear cleaner during testing that they are in real-world driving. The charges were revealed last week by the EPA, which cited the work of researchers at West Virginia University. About 482,000 vehicles are affected in the United States, which will be subject to recall, and VW estimates about 11 million of its vehicles around the world have the rigged software. The well-regarded Muller was viewed as a front-runner for the job even before Winterkorn stepped down. Before helming Porsche, he oversaw all vehicle projects globally for VW from 2007-2010. Previously, he was in charge of the Audi and Lamborghini product lines, and earlier in his career was responsible for the Audi A3 program in the 1990s. He joined Audi in 1977. He's trained as a toolmaker and studied information technology in Munich. His last name is sometimes spelled Mueller in English. Muller faces immediate challenges as he takes over VW's sprawling 78-year-old industrial empire, including recalls and regulatory actions around the world. In the US alone, the company faces a fine of up to $18 billion. VW, an industrial symbol of Germany, is also far larger than any unit Muller has run in his career. While Porsche sold 189,849 vehicles in 2014 globally, it's one of many VW brands. Collectively they sold 5.04 million vehicles through the first six months of this year, making Volkswagen the world's largest automaker. Related Video:
