Porsche Cayman GT4 speeds back into view

We're all familiar with the succession of numbers that follow the letters GT on a hard-core Porsche 911: the GT1 that was Stuttgart's Le Mans contender in the late 90s, the GT2 that packs turbochargers but without the Turbo's all-wheel drive and excess weight, and the naturally aspirated GT3 that's the enthusiast's choice. But a GT4? That's something new, and exactly what Porsche has in store.
Spied testing in Germany once again is the upcoming GT4 version of the Porsche Cayman, set to supersede the existing GTS and take the place of the previous Cayman R at the top of Porsche's junior sports car range. This latest batch of spy shots doesn't show us much more than the last crop, but gives us a much clearer view at what promises to be the most hardcore Cayman to date.
As you can see, the Cayman GT4 packs a much more aggressive aero kit and rolling stock than any version we've seen to date. It's got a lip spoiler, big air dam and GT3-style vent in front of the hood, deep air scoops along the flanks, a set of spindly alloys packing oversized brakes, a diffuser with twin central exhaust tips around back and a rear wing that's likely to be replaced with a sleeker unit before the GT4 reaches production.

Jay Leno welcomes Emory's outlaw Porsche 356s

Classic cars can have a lot of character, but purposely passing up on some of the enormous advancements made to the automobile over the decades since those classics were made can be a difficult proposition. That's where restomodders like Emory Motorsports come in. Emory specializes in customizing Porsche 356s, modifying them to their clients' specifications and giving them an added dose of performance and refinement, all without losing that timeless appeal. The LA-based company is headed up today by third-generation Southern Californian gearhead Rod Emory. After seeing some examples of his work out on the road, Jay Leno invited Rod by the garage along with a pair of his company's custom creations. Both are based on 356 coupes from the late 1950s, but take pretty different approaches in their comprehensive restoration and extensive modification. Since classic Zuffenhausen enthusiasts are notorious for their rigid adherence to originality, Emory's modified 356s are deemed to be "outlaws" by many on the vintage Porsche scene. But they've also gained quite a following, similar to what Singer has done with 911s. Whether you're more inclined to cling to authenticity along with the purists or embrace the novelty espoused by the restomodders, after scoping out these irresistible specimens, you'll have to admit that Emory does some pretty compelling work. Watch the 25-minute video clip above to see what we mean, and check out Petrolicious' profile of the same company's work from last year for another look.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models.
