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 911 with VW turbodiesel prepares for LeMons assault

LeMons racing is a wonderful example that setting limits can actually breed creativity. The series mandates that all entries must cost $500, not counting safety equipment, and that cap forces teams to be ingenious in how they build a racecar. Take for example this diesel-powered Porsche 911, which its creators have dubbed Ferkel the Nein-11, that will be racing in the Sears Pointless race this weekend in Sonoma, California.
This Frankenstein combines a 911 chassis that was originally bought just for its European powertrain and a Volkswagen TDI diesel engine mounted in the rear. After deciding the shell could still be of some use, the team decided to go racing. "We began brainstorming what replacement drivetrain to use for maximum offense and there was really only one answer: a diesel," said Philipp von Weitershausen, one of the team captains, to Jalopnik. They bought a 1998 Jetta TDI on the cheap and started figuring out a way to hack the engine into the bay. To pay respect to the donor, the VW's trunk was highly modified (and drilled) and grafted onto the back of Ferkel.
This team isn't a newcomer to LeMons. Its last car was a classic VW Beetle with a Subaru engine and dual controls, named Ferdinand the Bug, which could be driven from the left or right side. It's quite a sight.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models.
