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.

Porsche 5 Series fighter may be electric

We know that Porsche is developing a seventh model range for its lineup thanks to the March announcement from company boss Matthias Muller. The actual identity of this future vehicle remains a mystery, though. Autocar is coming down firmly on the side of the smaller Panamera, codenamed the Pajun, and speculates the new entry might be available in battery electric and hydrogen fuel cell versions based on recent patent filings. Porsche is famous for sticking with the rear-engine layout on the 911 for decades, even as the company moves the powertrain forward in other models. According to Autocar, the EV version of the Pajun might mark a return to these roots. The German brand is reportedly preparing a modified version of Volkswagen Group's MSB platform for the new vehicle. Called eMSB, the setup puts the batteries and electric motors at the back, and each rear wheel would receive power separately to allow for torque vectoring. The system is estimated to generate 420 horsepower, which is on par with the all-wheel-drive Tesla Model S 85D. The fuel cell Pajun would join the lineup later. The Pajun is rumored to take on the likes of the BMW 5 Series and Mercedes-Benz E-Class, but any luxury EV of that size must count the Tesla Model S as a competitor, too. According to Autocar, the styling takes cues from the Panamera Sport Turismo concept (pictured above) and could launch around 2018. Rumors of Porsche's Tesla-fighter were swirling for months before Muller's announcement, and talk of the Pajun has gone on even longer. Previous reports have suggested the possibility of a 300-mile range and an all-wheel-drive layout with 600 hp. While the actual design has remained ambiguous beyond the potential link to the Panamera, the model was possibly spied last year at the Porsche Design Tower in Florida.

Xcar considers the Porsche 911 GT3's PDK

Porsche ruffled some feathers when it unveiled the latest 911 GT3 a couple of years ago with a dual-clutch transmission instead of an old-school manual. The rationale was (and remains) that the PDK makes the enthusiast's Elfen faster than it would be with a stick. The purists scoffed, but Zuffenhausen held firm – and even did the same with the even more hardcore GT3 RS. In its latest video, the boys at Xcar set out to find out if the GT3 with its fancy automated gearbox is as good as the previous model (or as good as the current model could be) with a manual – and took in some of the track toy's other trickery while they were at it. Check out the video above to find out what conclusion they reached.
