2014 Porsche 911 Turbo Cabriolet spotted testing in the nude

The Porsche 911 wouldn't be the Porsche 911 unless there were twenty-something different models to choose from (note: we are not complaining), and the latest one was just spied by our trusty photographers out on Germany's Nürburgring. Feast your eyes on the 911 Turbo Cabriolet - the droptop version of the new Turbo wonder that debuted in May - looking all sorts of stealth in its black-on-black-on-black prototype scheme.
Mechanically, the 911 Turbo Cab should be identical to the fixed-roof version, meaning a twin-turbo 3.8-liter flat-six engine will live in the car's rump, putting out something like 520 horsepower. Of course, there's also the hotter Turbo S version of the coupe, and we expect that to get the droptop treatment, as well, with 560 horsepower on tap. The added weight of the folding top and additional structural supports will likely make for slightly slower 0-60 times for both cars, though considering the base Turbo will hit 60 miles per hour in 3.2 seconds, "slower" is a very relative term indeed. All that force will run to the ground via all-wheel drive, managed by Porsche's seven-speed PDK dual-clutch transmission.
The wide stance of the 911 Turbo Coupe carries over to the Cabriolet, no doubt fitted with the same (standard) 20-inch wheels. Inside, the usual luxury amenities will be on hand, along with nearly endless customization options.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.

Porsche says next Cayenne will be faster than Bentley Bentayga

Bentley and Porsche are both high-end marques under the same umbrella, and may even be collaborating on development of new models – but while they tend to take different approaches and go after different customers, that doesn't mean they can't share a bit of sibling rivalry. And that spirit of competition – even within the Volkswagen Group – looks to be coming to a head in the form of their upcoming luxury performance crossovers. For his part, Bentley CEO Wolfgang Durheimer promises that the brand's upcoming Bentayga sport-ute will (in its top spec with the W12 engine) be the fastest SUV on the market. But in speaking with Car and Driver, Wolfgang Hatz – who holds the Porsche R&D head office that Durheimer used to occupy – says the Bentley won't be king for long. Porsche just released the new Cayenne Turbo S in Detroit, touting it as the first SUV to crack the eight-minute barrier at the Nurburgring. And Hatz says that the next version will be even faster. "Our Cayenne is always very very quick. It is doing 300 km/h [186 mph]. I think if [Durheimer] is doing 2 to 3 km/h more, then why not? He's doing that with a 12-cylinder. Our car will be much quicker on the road." The next Cayenne is slated to use a new generation of engines, and according to Hatz, will benefit from the same (if not more) weight loss as the new Audi Q7 with which it will share its platform. That sounds like a winning combination to us. That is, at least, for fans of performance crossovers. For those who aren't, Porsche promises it won't be bolstering its lineup with any new ones. Apparently the Cayenne and the smaller Macan are enough. Nor will Zuffenhausen slot anything bigger than a V6 into the Macan, according to the report. While Porsche's baby crossover will surely continue to get faster with new iterations, the Cayenne will always remain the performance flagship of its SUV range.
