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.

Petrolicious studies the purity of a Porsche 911 2.7 RS

Water-cooled Porsches are superior to the old, air-cooled models. This really isn't up for debate, despite the mob of Porsche purists, with pitchforks and torches in hand, currently descending on the Autoblog offices. Water-cooled models are more powerful and easier to live with, two factors that make modern Porsches just so darn amazing.
And while we won't hear arguments on anything we've written above, we will say that the old air-cooled models, while not superior, are just, somehow, better. They sound better - a lot better. They're simple, elemental and wildly entertaining things, that just beg for more and more. They rev in a way that forces drivers to work to unlock their power, rather than just push their right foot down. Part of the appeal of air-cooled Porsches, in addition to what we just listed, are the gorgeous cars they're slotted into, like the subject of the latest video from Petrolicious.
Starring a 1973 Porsche 911 Carrera 2.7 RS, this video is a bit shorter than recent ones, but it's no less exciting. This 911, complete with it's sweet-sounding exhaust is the kind of simple, entertaining thing we can watch over and over. Scroll down for the full video.

Techart modified Porsche 911 Turbo S packs 620 hp, 0-62 in 2.8 seconds

Considering how many absolutely ridiculous tuner cars are featured in Geneva (stay tuned to see plenty, as our coverage continues), it's often refreshing to see some of the more modestly modified cars, like this new Porsche 911 Turbo S from the folks at Techart. Visually, there's a subtle body kit, new wheels, a new spoiler, and some lame decals on the front end, but it basically ends there. That's because Techart's mission is really about higher performance. Increased dynamism, as the Germans say.
An ordinary 911 Turbo S produces 560 horsepower and 516 pound-feet of torque. But the Techart kit adds 60 hp and 96 lb-ft to those already high numbers, for a coupe that dishes out a total of 620 hp and 612 lb-ft. Techart says that, in Sport Plus mode, its modified 911 Turbo S will accelerate to 62 miles per hour in just 2.8 seconds, and the top speed has been increased to 204 miles per hour. Crazy stuff.
To further drive its performance upgrades home, Techart has fitted this 911 Turbo S with a sport exhaust system with valve control, for a more robust exit interview, at the push of a button. We imagine it sounds awesome. Have a look at the Techart Turbo S in the gallery, above.
