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 918 Spyder gets tiny recall for rear control arms

As the recent US recall of a single Koenigsegg Agera shows, even low-production supercars aren't immune from safety campaigns. Now, there's another example that even the fastest cars can have their faults. The Porsche 918 Spyder is a pretty fantastic vehicle for its ability to mix hybrid fuel economy and incredible amounts of power, but Porsche has a problem on a few units of its halo model.
According to the recall document from the National Highway Traffic Safety Administration, Porsche needs to inspect and possibly repair five 918s in the US because the rear axle control arms may break, which could cause a loss of control while driving. In the full defect notice, Porsche says that it first noticed the problem on June 26 when the parts failed during "heavy duty durability testing (extreme race conditions)" at the Nardo test track in Italy. It transported the components back to the company's lab for inspection, and on July 18 it issued a stop-sale to inspect the suspension parts on the supercar. The automaker also contacted owners by phone to warn them not to use the car on track, until repaired.
The affected 918s will be inspected, and if the cars have the bad parts, the control arms are will be replaced. Obviously, this will be done at no cost to owners. According to a Porsche spokesperson speaking to Autoblog, in addition to the five US cars potentially affected, there were 45 worldwide. All of the cars have now been checked.

Recharge Wrap-up: Tesla Model X towing drag race, Porsche 918 salvage auction

Watch an Alfa Romeo 4C drag race against a Tesla Model X towing an Alfa Romeo 4C. The ridiculous (or, perhaps more appropriately, ludicrous) race appeared in MotorTrend's Instagram, which was then shared on Facebook by Tesla Motors Autopilot Program Director Sterling Anderson, along with the comment, "Fun fact: many high-performance cars cross the quarter mile line faster when towed by a Model X than they do on their own four wheels." While we can't quite see the actual results of the drag race in the video, it appears to be a close one. Check it out in the video above, and read more from Electrek. A Porsche 918 Spyder has gone up for auction. Unfortunately, it's a salvage auction, and said performance plug-in hybrid is totally mangled. The gut-wrenching photos reveal an even sadder detail, as the car's odometer shows it only logged 92 miles before being involved in what appears to have been a terrible wreck (though the listing describes the miles as "not actual"). The current bid on the Copart auction site is up to $106,000, and the listing shows a $600,000 repair estimate. The very expensive hunk of metal and carbon fiber is located in Long Island. Check out the listing for yourself, or read more at MotorAuthority. GKN Driveline says that German drivers are more interested in plug-in hybrids (especially with all-wheel drive) than conventional hybrid cars. In a poll of more than 1,000 drivers commissioned by GKN, 75 percent preferred PHEVs to standard hybrids, while 61.2 percent said that 50 kilometers (31 miles) of electric range is enough for their daily driving duties. About 81 percent are "wary of hybrids," most believing them to be a poor value. 52 percent said their ideal car would combine a plug and all-wheel drive. "We believe that plug-in hybrids with all-wheel drive make sense," says GKN Automotive President of Engineering Peter Moelgg, "and the public's positive response to vehicle programmes that offer this combination – like the Volvo XC90 T8 Twin Engine, BMW i8, and Porsche 918 Spyder – can only continue to grow."
