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.

Watch this Koenigsegg CCX hit 211 mph on a runway, outpacing McLaren's P1

Vmax200 in in England organizes events where those who care to show up with a supercar can run them down the two-mile runway at Bruntingthorpe Proving Ground. Evo attended the latest event, bringing an impressively green Lamborghini Aventador to test its girth and gaping vents against other precious metals like the McLaren P1 and F1, Ferrari F12 Berlinetta and Enzo, a Porsche Carrera GT and enough 911 Turbos to start a dealership. Speaking of those Porsches, nine of the top ten slots in the top speed competition are claimed by modified 911 Turbos.
A monochrome Swede ruled them all, though, a black-and-white Koenigsegg CCX setting fire to the speed trap run after run, hitting 211 miles per hour at its quickest. It was followed by, surprise, a 911 GT2 modified by 9E that did 210 mph. You can watch the EVO video below, GT Spirit has a bigger breakdown of the day, and we've included another vid showing the tandem launch of the CCX and McLaren F1.

1973 Porsche 911 Carrera RS takes center stage with Petrolicious

Today, one of the most exciting track toys available is the Porsche 911 GT3. Its forbearer, though, was an altogether different beast that was every bit as exciting. Yes, we're talking about the old 911 Carrera RS that blessed the early 1970s. With a mere 1,580 cars built, meant specifically to satisfy the FIA's homologation requirements, the RS is one rare pre-Malaise era cars.
Complete with a 2.7-liter flat-six engine, this RS of Mark Haddawy is one of the earlier examples of the breed (later cars received a larger, 3.0-liter engine). Still, it can scamper to 60 miles per hour in a very respectable 5.6 seconds and will happily hit 150 mph in a straight line. Sporting Porsche's iconic duckbill rear spoiler, the equally iconic Fuchs wheels, as well as slew of options, as Haddawy points out, each of the nearly 1,600 RS models is its own unique iteration on the Porsche performance formula.
Take a look below for the latest video from the crew at Petrolicious.
