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: Porsche adds third 919 Hybrid for Le Mans, Audi to heat factory with geothermal

Porsche will be running a third 919 Hybrid LMP1 car in the 2015 24 Hours of Le Mans endurance race. The extra Porsche will race in the six-hour May 2 WEC race at Spa-Francorchamps as a lead-up to the legendary 24-hour race on June 13 and 14. Porsche hasn't announced the driver lineup for the third 919 Hybrid, but drivers will remain the same for the other two cars. Including the third car is meant to help further test performance and efficiency as part of development for future hybrid systems. Read more at Green Car Congress. BMW i Ventures is investing in Zendrive, a driving focused data and analytics company. The cooperation of the two companies is meant to help advance safety and efficiency by making the "in-car mobility experience even smoother by optimizing commuting and driving patterns," according to BMW i's Ulrich Quay. The venture capital arm of BMW's i brand also invests in JustPark, Chargepoint, Life360, Chargemaster and MyCityWay, and says it will have more strategic investment announcements in the coming months. Read more in the press release below. The Audi Hungaria factory in Gyor, Hungary will soon be getting geothermal energy from a nearby plant being constructed in Per. When the facility is finished, Audi expects to source 82,000 megawatt hours of geothermal energy per year from it, or about six percent of its total heating needs. The clean energy helps Audi move "step by step along a path to developing a CO2-neutral production plant," says Audi's Dr. Hubert Waltl. "The mobility of the future must be CO2-neutral – and that applies not only to the use of our vehicles, but also to their production." Read more in the press release below. Supporters have begun a petition drive for the passage of an E15 ordinance in Chicago. Despite pushback from oil companies, the city council is close to passing the "Chicago Clean Air Choice Ordinance," which includes the requirement by retailers to sell the 15-percent ethanol gasoline blend in the city. The ordinance includes an exception for stations selling less than 850,000 gallons of fuel per year. More than 4,000 people have signed the petition so far, with others leaving messages to voice their opinion on the matter in opposition to Big Oil's attempt to block it. Read more at Domestic Fuel.

Magnus Walker turbocharges his love for the Porsche 911

He's had his fill of early, long-hood Porsche 911s - he owns at least one from each model year, from 1964 to 1973 - so Magnus Walker, a fanatic of the Stuttgart, Germany-based automaker, recently set his sights on the early Porsche 930, as documented by this XCAR video called 'Turbo Fever.' Let us translate: pretty soon Walker will own all of the earliest, non-intercooled 911 Turbos - at least one from each model year, starting at 1975 and ending at 1977 (though the 1975 911 Turbo Carrera never officially was imported to the US by Porsche, so it'll be tougher to find one Stateside).
Any Porsche enthusiast can tell you why they love their car, and it often comes down to the small details that differentiate one model year from another. One of many examples is the mid-'80s 928. They look similar, but the basic difference between a 1984 Porsche 928 S and a 1985 928 S (US-spec) is two camshafts and 54 horsepower, though each car's V8 has its own pros and cons. We'll let Magnus Walker tell you all about the 930 and what makes the first three years special, as he's becoming quite the expert on early, air-cooled 911s. When the nearly 15-minute mini-documentary was filmed, which you can view below, he already had added four early 930s to his collection!
