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.

Will Roegge makes 4K art of Jeff Zwart's 911 build and run up Pikes Peak

Will Roegge has turned his camera on Jeff Zwart and provided another gem, this time documenting Zwart's run up Pikes Peak and BBI Autosport. Bertim Besha dropped out of high school, then worked his way up to founding his own shop, BBI, that gathers a crew of tuners who are just as fastidious about their work as the customers are about their cars.
They prepped the 991-series Porsche 911 GT3 Cup Turbo, the product of combining a 911 GT2 that was the most powerful car Zwart drove up the mountain with a GT3 Cup that Zwart thought had the best handling. Two TiAL turbos and a lot of fettling make for a 3.8-liter flat-six with 700 horsepower, 700 pound-feet of torque and a 7,800-rpm redline. Zwart drove it to a heartbreaking second place this year, finishing less than 1.2 seconds behind the Time Attack 1 class winner when his car suffered its first mechanical issue of the week.
The first video below covers Besha, BBI and the build, the second is Zwart's run. As if the visuals weren't enough, sit back and enjoy the shrieking of the "Hill Climb Special," which is what the constellation Sirius would sound like if it could bark.

Porsche Macan fails moose test, Stuttgart responds

Different countries have different safety standards, but most of them revolve around a similar set of tests: front impact, side impact, offset impact, rollover... the usual. But Sweden has its own test. It's called the Moose Test (or the Elk Test), and it's unique to Scandinavia: a car has to be able to avoid a theoretical antlered mammal on the road while traveling at 43.5 miles per hour and return to its previous course without flipping over. The Jeep Grand Cherokee ran afoul of the uniquely Nordic maneuver a couple of years ago, but even more surprising is the way the Porsche Macan has reacted.
Under testing by Sweden's Teknikens Värld, Porsche's downsized crossover - specifically the Macan S Diesel, for what it's worth - didn't flip over, but it skidded off course. In real-world conditions, it follows, the vehicle could run off the road or into oncoming traffic. The testers ran the test several times, and even removed excess weight from the vehicle, and each time it reacted the same way.
In response, Porsche has explained that the behavior is the result of its Active Rollover Protection system kicking in. When the system detects that the vehicle could drastically oversteer, flip over or lose its tire, it momentarily applies the brake on the front outside wheel, allowing the vehicle to shed the cornering forces without losing it completely.
