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.

5 highlights from the 2018 Petersen Automotive Museum Auction

From the avant garde exterior design to the collection of vehicles between the walls, the Petersen Automotive Museum in Los Angeles is one of the coolest car museums in the U.S., and possibly the world. Among several others, the Petersen has two featured exhibits, The Porsche Effect and Legends of L.A. But the museum has a different type of viewing coming up at which you could touch, or even buy, a variety of special vehicles. After hosting its SoCal auction on the coast in Santa Monica for several years, RM Sotheby's has moved the event to the more central location of the museum. In addition to several works of art, the auction which takes place the weekend of December 7, will show several dozens of blue-chip vehicles, chosen by RM Sotheby's 30 car specialists. After sorting through lots that range from microcars to new-age supercars, here are five of the highlights that caught our eyes. 1956 Ferrari 290 MM by Scaglietti Projected Value: $22,000,000-$26,000,000 Without question, this is the crown jewel of the entire show. As the eldest and most experienced of the 11 total Ferrari lots, its estimated value of $26 million is more than five times the values of the other five cars listed below combined. From the jump, Ferrari threw the 290 into the line of fire. Starting its life with a four-cylinder 860 Monza engine and a Tipo 520 chassis, its first race was the Mille Miglia. Peter Collins was behind the wheel and racing photographer Louis Klemantaski was his copilot. Ferrari took the top five spots in the race, with this car, chassis No. 0628, finishing second. It went on to see multiple races and took on multiple forms, including a V12 swap at one point. After switching through the hands of multiple owners, it was sent to Ferrari Classiche in Maranello, where it was restored to its form at the time of the 1957 12 Hours of Sebring. It retains its original chassis, original bodywork, and original transmission, and houses the V12 from its 290 MM spec. The restoration was completed in 2015, and the car remains in incredible shape today. 1971 Lamborghini Miura P400 SV by Bertone Projected Value: $2,100,000-$2,500,000 Simply put, the Miura is one of the most significant supercars, and therefore one of the most important cars, of all time. Its two-seat, mid-engined configuration seismically shifted what a performance could and should look like, and its V12 gave it the power to be the fastest car in the world when it debuted.

Watch a Cayenne Turbo S, Range Rover SVR, and Cherokee SRT drag race

We live in a weird world where high-performance SUVs could win a 60-mile-per-hour sprint against sports cars from just a few years ago. Here, Top Gear sets up a three-way drag race against the Porsche Cayenne Turbo S, Land Rover Range Rover Sport SVR, and Jeep Grand Cherokee SRT, and the results show just how quickly these high-riding models can cross the quarter mile. The Cherokee SRT is the patriotic choice among the three, but it's down on power in this fight. Meanwhile, the Range Rover's menacing growl sounds the best, and the Cayenne Turbo S has the most horsepower. You'll have to watch the video to see which SUV will win this battle. Related Video:
