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 offers design walkthrough of Panamera Sport Turismo

The Porsche Panamera Sport Turismo was arguably the best concept car of 2012, and Porsche has been building upon that momentum by teasing us with videos of its first-ever station wagon design. After showing us some driving shots of the Sport Turismo, Porsche released a more in-depth and behind-the-scenes look at what it took to take the Panamera shooting brake from a full-scale clay model to the final product we saw on stage at the Paris Motor Show. In the video, Michael Mauer, Porsche style director, and Mitja Borkert, general manager advanced design style, both give a little insight about what went into creating the Sport Turismo Concept.
More than just a station wagon version of the Panamera, the Sport Turismo has a totally distinctive look nose to tail. Some of the key elements the designers touch on in the video include the Porsche-signature raised front fenders, the wide rear shoulders, the front wing inspired by the 918 Spyder, and even some of the car's unique touches, including the headlights and the three-dimensional "Porsche" lettering across the liftgate made from glass. One of the more exciting aspects of the concept - which is sadly just glossed over in the video - is the rear liftgate spoiler that features "variable aerodynamics" that sounds like it acts similar to the retractable spoiler on the current Panamera.
We still don't know if the Panamera Sport Turismo will make it into production, but if you want to see what went into creating this exciting concept car and see the different build phases designers went through to create the Paris show car, check out the video by scrolling below.

1974 Porsche 914 EV conversion still looks good

Looking through the pages of the EV Album is a great way to learn about the breadth and depth of the electric vehicle community. Branching well beyond the three dozen or so electric vehicles that are currently sold by major automakers in the US, EV Album showcases lots of DIY conversions of all types. A 1995 Fiat Cinquecento? Check. A 1992 Kewet Eljet 2? No problem. The site's old-fashioned looks (it was started in 1997) show just how long people have been passionate about their EVs. Many of the cars are throwbacks to a previous time and we found a prime example of that, a converted 1974 Porsche 914 (EV Album page here) this week. Now powered by a Prestolite MTC4001 Series Wound DC motor and some flooded nickel-cadmium batteries, the 914 has a top speed of 80 miles per hour and a range of 35 miles. But only "if you are taking it easy," of course. The motor has a peak output of 60 horsepower and 25 hp continuous. Converted over 600 hours (!) to electric power at a cost of $10,000, it is now owned by Charlie Garlow of Maryland. The car is on display at the Washington Auto Show this week and serves as a great reminder of what most EV drivers used to have to do to drive emissions free.
