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.

Five cursed and haunted cars

Any kid lucky enough to grow up in Detroit is familiar with the Henry Ford Museum. It's huge, full of shiny things and a great place to take a child and let them burn off some energy. After several field trips and weekend outings however, the dusty concept vehicles and famous aircraft tend to lose their punch for youngsters. As a fifth grader, I was already gazing on the museum's many gems with glassy eyes. On yet another school trip, we made our way to John F. Kennedy's death car, a gleaming black Lincoln limo. The aging volunteer docent told our little group something I had never heard before. "You know, this car is haunted. Several employees have reported seeing a gray presence right here," he said, pointing to the back passenger side seat. I perked up. Now here was something I had never heard before. A haunted car? Sure, it happened in Goosebumps, but this was real life. It made sense, in a way. Cars can be violent, emotional places. That's certainly the case with JFK's limo, as well as the other four cars on this list. And maybe those gut-wrenching deaths can permanently doom a car. 5. Archduke Franz Ferdinand's Graf & Stift Death Limo World War I tends to be a forgotten war, despite being pretty terrible in its own right and setting the stage for the entire 20th Century. The French forces, for instance, lost more lives in the first month of WWI than the US did in the entire Civil War. Everyone who has been through a freshman world history course knows the conflict started when Archduke Franz Ferdinand and his wife were shot by a Bosnian anarchist. The crazy thing is, Ferdinand had already avoided an attempt on his life that day, and was actually on his way to the hospital to comfort those who had been injured in the crossfire. One of the would-be assassins simply walked out of a cafe and saw his intended target sitting in front of him where the open-air limo had stalled. The archduke and his wife were shot through their heads and throats. Their deaths would not be the last caused by the limo. Throughout the war and into the 1920s, the limo was owned by fifteen different people and involved in six accidents and thirteen deaths, not counting the 17 million or so killed in the war triggered by the Archduke's assassination. The first person to own the car after the Archduke was an Austrian general named Potiorek, who went insane while riding in the car through Vienna.

700 horsepower Porsche GT2 RS is the wildest 911 ever

The Porsche 911 comes in a variety of flavors, each filling a certain taste for a certain customer. Sitting atop the range is the new 911 GT2 RS. In previous generations, the GT2 had a bit of a reputation as a widowmaker, a 911 with massive power that could snap and bite with the slightest agitation. Porsche says the new model has been civilized, but with 700 horsepower going to the rear wheels, we're sure it's going to be as mad as ever. Power comes from a highly massaged version of the 3.8-liter flat-six from the 911 Turbo S. The rear-mounted engine makes an outrageous 700 horsepower and 553 lb-ft of torque. Like we previously reported, the new car will use water injection to help keep things cool. The only transmission is Porsche's PDK. While enthusiasts may lament the loss of the manual, the RS models have always been about performance above all else. Simply put, the PDK is the better performance option. All that power translates to a 0-60 mph time of 2.7 seconds and a top speed of 211 mph. The engine makes 80 more horsepower than the previous model. That makes it the most powerful road-going 911 ever built. In fact, the 887 horsepower 918 Spyder is the only road-going Porsche that makes more power. The fact that Porsche trusts all of that power to go to the rear is both thrilling and terrifying at the same time. In order to manage traction, the GT2 RS gets a number of upgrades. Rear-wheel steering has become commonplace in the 911 lineup, so it's no surprise to see it here. Sticky tires with 265/35 ZR 20 section rubber at the front and 325/30 ZR 21 section rubber at the rear keep things planted. That comically large rear wing adds downforce, adding to stability. The car gets standard carbon ceramic brakes. While some people prefer traditional rotors for the street, like the PDK, this is all about performance. A number of intakes and outlets complement the rear wing and maximize aerodynamic efficiency. It's a bit of a surprise that with all the focus on downforce, the GT2 RS still manages to top out at 211 mph. The hood, front wings, wheel housing vents, door mirrors, side air intakes, parts of the rear end, and a number of interior components are all made from carbon fiber. The roof has been made of magnesium. If you want to drop any pretense of civility and comfort in the pursuit of speed, Porsche is offering a Weissach package that shaves off another 40 pounds from the already impressive wet weight of 3,241.
