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.

Recharge Wrap-up: Big Oil fails at renewable fuel, scientists study air with EVs, plug-in Panamera sales

Big Oil companies help keep renewable fuels out of your tank, a new report shows. No surprise there, right? The Renewable Fuels Association published a report card grading the country's largest retail gasoline chains on fuel offerings like E85 and E15. The report gave failing grades, with less than one percent of stations offering E15 or E85, to "Big Five" companies Exxon, BP, ConocoPhillips, Chevron and Shell, among other oil company and convenience/grocery store brands. The only major oil companies that didn't get an "F" were Valero (D), Cenex (B), and Marathon (A-). The eight companies that scored an A+ had at least 25 percent of their stations offering E85 or E15.

Beginning July 4, University of Leicester researchers began driving electric vehicles kitted out with special sensors to monitor air quality throughout the city (similar to how California does it). Now their emissions-free daily driving duties double as data collection for their studies. "By monitoring air quality as a seamless part of our daily transport system, we are providing a cost-effective way to help inform future policy and operational systems," says the University's Dr. Roland Leigh.

"There is no doubt electric cars are the future." – Nissan's Andy Palmer Nissan is exploring the idea of taking its Leaf EV to India, but a lack of charging options is an obstacle. According to Nissan's chief planning officer Andy Palmer, "There is no doubt electric cars are the future. The product is there, what we need is infrastructure. Charging is a big challenge." Though Nissan stopped short of saying it (this time), this could possibly mean working with Mahindra, which said it is open to collaborating with other companies concerning EVs. Learn more in this article from the Hindustan Times and know that India is rolling out a plan to encourage the production and adoption of EVs. The National Electric Mobility Mission Plan will get over $2 billion in funding, and some of that will go toward creating a charging infrastructure (you hear that, Nissan?). This is good news for EV manufacturers, India's economy and people who enjoy breathing clean air.

Porsche 911 Cabriolet refresh may hide new engine

If we learned nothing else from our recent frolic through Porsche's secret museum, it's that the automaker goes to incredible lengths to disguise future products during initial testing. Just as a number of cars in that Stuttgart bunker hid the true identity of developmental mules (like the Audi-V8-powered 911), such could very well be the case with these spy shots showing what, on the surface, appears to be simply a facelifted 991 911 Cabriolet.
Similar to what we saw last month on a 911 coupe, this Cabriolet has obvious styling modifications made to the front and rear fascias suggesting that the 911's still-fresh appearance is already set to get a few tweaks. The big news here is at the rear of the car. The additional vents on the lower edge of the fascia and the mocked-up vent above the engine leads our spy photographer to believe that a new engine could be tucked under the body work - likely a smaller-displacement, turbocharged flat-six focusing more on improving fuel efficiency and reducing exhaust emissions rather than performance.
We last heard rumblings of such a detuned 911 back in August, but could this be our first look at said new model? Have a look for yourself, and let us know what you think - either about this mule specifically or the idea of a "green" 911, in Comments below.
