Porsche testing four-cylinder Boxster at the N?rburgring

Porsche recently introduced a four-cylinder version of the new Macan for markets outside of North America, carrying Zuffenhausen's first four-pot since the 968 ended its production run the better part of two decades ago. But you can bet the compact crossover won't be the only Porsche to get the four banger before all's said and done. These spy shots, we're told, are evidence of just that.
Spotted undergoing testing at the Nürburgring (where else), this modified Boxster, our spy photographers tell us, sounds more like a four-cylinder engine than the flat six that's powered (in displacements ranging from 2.5 liters to 3.4) every version of the little roadster since its introduction in 1996, the year after the last four-cylinder Porsche ended production.
The test mule is also wearing modified wheel arches and aerodynamic aids under the bumpers, front and rear. Just what they're doing there we're not sure, but we'll probably find out sooner or later.

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.

Updated J.D. Power APEAL study shines on VW Group, Chevy

J.D. Power has just revealed the results of its 2013 APEAL Study, which looks at which brands have the most appealing cars based on sales figures, dealer inventory, brand loyalty, transaction and trade-in prices. The study was revamped for 2013, and places a larger focus on the new tech and infotainment options available to customers. All told, study participants gauged their vehicles on 77 different attributes, delivering a score out of a 1,000 points.
The Volkswagen Group had the greatest success of any corporation, topping the APEAL rankings with the Audi Allroad, Porsche Boxster, Porsche Cayenne, VW GTI and Passat. Chevrolet had the highest number of awards for a single brand, though, with the Avalanche, Sonic and Volt all taking home a prize.
The best brand overall was Porsche, which scored 884 out of a possible 1,000 points. The top Japanese brand was Lexus with a score of 847, while the top American brand was Cadillac, at 841. The best mainstream brand was Ram, which received a very respectable 817. The industry average for this year's study was 795, with 16 brands, all of which were mainstream, falling below the average.
