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.

NHTSA closes probe into 2011 Porsche 911 coolant leaks

The National Highway Traffic Safety Administration has announced that it will end its investigation into rapid coolant loss in 24,635 Porsche 911s built between 2001 and 2011. The models affected included the standard 911, GT2, GT3 and Turbo, as well as their variants (GT2 RS, GT3 RS and Turbo S).
NHTSA was investigating for "rapid coolant loss caused by coolant pipe-fitting failure, allegedly resulting in vehicle disablement and/or loss of vehicle control due to reduced traction for the affected vehicle or following traffic," according to the regulators website. "Most of the leak complaints did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked," said NHTSA's statement.
There were 63 complaints and 336 warranty claims, although the investigation was initiated after ten complaints from customers. There have been no reports of crashes or injuries attributed to rapid coolant loss.

Hot Wheels goes Outlaw with Magnus Walker Porsches

Magnus Walker, of Urban Outlaw fame, insists his story is just like that of any kid. But instead of becoming a fireman or an astronaut, Walker's childhood dream was to have a specific car. A Porsche 911 Turbo just like the one he fell in love with at the 1977 Earls Court Motor Show in London, to be exact. Today, he's famous both for having an eye-catching collection of 911s, as well as a compelling story behind them. Walker collaborated with Hot Wheels so a new generation of kids can find their dream, just like he did with that Porsche. Today, Walker and Hot Wheels will unveil the line of diminutive Porsches he helped to create, starting with the company's beginnings: a Porsche 356A. "There was something about this car, the Porsche," Walker told Autoblog last week in his Downtown Los Angeles garage. "You either had the Ferrari Boxer on the wall, a Lamborghini Countach on the wall, or a Porsche Turbo. There was something that attracted me to this car. That dream never went away." Jun Imai, Design Manager at Hot Wheels, said Walker's story and ties to the Porsche name were a match for the maker of toys that are commonly found on a living room rug. "All Hot Wheels cars have a story, just like all the cars in his collection," Imai said. The partnership with Waker, Imai said, is a product of the way Hot Wheels now gauges the pulse of car culture, with inspiration coming from what's parked out on the streets, printed in magazines and being shared on the internet. There was something that attracted me to this car. That dream never went away. "Up until five years ago, we were a V8 muscle car brand," Imai said. "Now it's, 'What is the modern hot rod?' It could be a Porsche or an E30 BMW. Everyone's into something different, so we take that into consideration." Imai said that Walker's collaboration is just that, rather than slapping his name onto a new series of products. "We're not just doing replicas of his car, that's almost obvious and easy," he said. "We thought, let's have him come in, let's have him actually design graphics for the cars where he's an integral process." For Walker, though, the Hot Wheels cars reflect the growing accessibility of car culture. Despite the modern popularity of video games - Magnus made an appearance in the latest Need for Speed game - Walker says the appeal of Hot Wheels spans from the youngest budding enthusiasts to people older than the original 356.
