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.

2015 Porsche Cayenne GTS proves performance is relative

The Turbo may be the most powerful model in the Cayenne range, but the GTS is arguably the enthusiast's choice. (In so far as a 4,500-pound crossover can be considered an "enthusiast's choice," anyway.) And now, after refreshing the rest of the Cayenne lineup, Porsche has revealed the new Cayenne GTS, alongside its new 911 GTS stablemate, here at the LA Auto Show. Like the new Cayenne S, the new GTS drops the previous version's atmospheric V8 for a 3.6-liter twin-turbo V6, but ups the output to 440 horsepower and 445 pound-feet of torque to propel Zuffenhausen's portliest to 62 in a scant 5.2 seconds. Alongside the power upgrade, the GTS gets a lowered air suspension and sportier exhaust, the beefier brakes from the Cayenne Turbo and an upgraded aero kit to help with the whole barn-door-profile thing. Just don't expect all that extra kit and the prestige of a Porsche badge on your crossover to come cheap, with prices starting at $95,500 (plus $995 destination).

Porsche 911 and Citro"en DS lovechild would look like this

The early Porsche 911 and the Citroën DS were two cars produced in the same era (though the DS launched in 1955, nearly 10 years before the 911), but they were vastly different from each other. The 911 was a uniquely German, pure-bred sports car, while the French-built DS had four doors and focused more on ride quality than sporting intentions. That made it all the more surprising when we came across the 911DS, a creation that binds the rear half of the Citroën to the front of an early, longhood 911.
The folks at Brandpowder are behind the creation, which we surmise was an exercise in design rather than an actual, completed project (some of the images look Photoshopped), but it's compelling nonetheless, with a turbocharged flat-six providing 260 horsepower. We hope someone builds it - though we're sure if that happened the early 911 crowd would cry afoul at one of its increasingly rare and valuable Porsches being grafted onto an old French car.
But as Brandpowder points out lightheartedly, perhaps the creation could transcend popular car culture: "The 911DS represents the effort of two countries, a genuine attempt to join their energy and talent into one thing. We hope Germany and France will be inspired by Brandpowder's story, as a metaphor for a better and greater Europe."
