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.

2014 Porsche 911 Targa

I've watched the electro-hydraulic roof panel open and close about 73 times in the past hour, but its fascinatingly complicated operation still has me mesmerized. I've concluded that only a German automaker - Porsche, to be more specific - would go through the trouble of engineering a roof system that essentially lifts the entire greenhouse off a vehicle, rearranges its components like a sliding-tile puzzle, and then reassembles all of them seamlessly (sans roof panel) to accurately recreate one of its most famed bodystyles.
The 2014 Porsche 911 Targa is a near-perfect modern interpretation of the automaker's 1965 911 Targa, a semi-convertible bodystyle that represents nearly 13 percent of all 911 models sold since production started 50 years ago. While the early car's roof was purely manual in operation - that's the period-correct way of saying that the driver did all of the muscle work - today's Targa is a completely automated transformation that requires only that the driver hold down a cabin-mounted switch for a mere 19 seconds to let the captivating show run its course.
After studying the Targa's elaborate roof operation at its launch at the Detroit Auto Show earlier this year, I was sufficiently intrigued. To that end, I traveled one-third of the way around the planet to southern Italy, hoping that the Mediterranean climate would reveal a bit more about the reintroduction of the automaker's iconic sports car.
