New Corvette Feature Keeps An Eye On Valets

Face it. If you own a luxury or sports car, whenever you hand the keys to a valet, you imagine the car going on a high-speed joyride like the Ferrari in the 1980s cult movie "Ferris Bueller's Day Off." Now, General Motors has an option on the 2015 Chevrolet Corvette that takes those worries away. The latest version of the sports car, due out in September, has a feature that records where the car goes with a camera mounted in the windshield trim. It also captures audio in the cabin as well as speed, engine revolutions per minute, gear position and G-force. That all helps the car tattle on any valet who doesn't take a slow, direct route to a parking space. GM says it's the most extensive attempt by an automaker to thwart valet joyriders, although it's not the first. The automotive website Edmunds.com says Hyundai and Mercedes offer "geofencing," a feature that sets a perimeter and then notifies the owner's smart phone if a car goes beyond it. Chrysler has a valet mode that caps engine speed and horsepower, while Audi lets owners limit engine speed for valets. With the Corvette, once the owner activates the feature with a four-digit code, the touch screen tells the driver it's in Valet Mode. But it doesn't warn the valet that he's being recorded. The feature also locks the glove box and a storage compartment in the dashboard and shuts down the infotainment system. Valet Mode started off as a performance data recorder for those who take their Corvettes on the racetrack. GM engineers quickly figured out that it had more uses. "Think of it as a baby monitor for your car," Corvette Product Manager Harlan Charles said in a statement. "Anyone who has felt apprehension about handing over their keys will appreciate the peace of mind of knowing exactly what happened while their baby was out of sight." Data and video from the valet mode can be viewed instantly by the owner on the car's 8-inch color screen when the car is parked, or it can be downloaded to a computer. The system could go into more mainstream models if feedback is good on the Corvette, GM spokesman Monte Doran said. The feature is paired with a navigation system and costs $1,795. A 2015 Corvette starts at just under $54,000. Chevrolet Technology Gadgets

Mustang, Camaro, Challenger gallop onto USPS pony car postage stamp set

Some of America's most iconic cars are about to be immortalized on postage stamps. A new set by the U.S. Postal Service will celebrate the the golden era of pony cars, featuring five classic examples of Detroit iron. Each one is beautifully illustrated in oil-on-canvas style, with subjects in motion and sunlight glinting off the chrome, and would add a nice touch to any first-class letter. The pony car segment was all about (relatively) small, sporty alternatives to the full-size land yachts of the 1960s. They typically came equipped with 6-cylinder engines or small-block V8s. The category was named after the Ford Mustang, hence  the name. Some, though, argue that the Plymouth Barracuda, which was launched a couple of weeks before the Mustang, is the first. Luckily, the Falcon-based Mustang's distinct styling generated a sales sensation, or we might be calling them fish cars. Appropriately, one of the featured cars is a Mustang. But it's not just any Mustang. The 1969 Boss 302, seen here resplendent in Bright Yellow, was created for the hotly-contested SCCA Trans-Am racing series. One of its main rivals would have been the 1969 Chevy Camaro Z/28, also created specifically for the series, and is included in the set in Fathom Green. Representing Auburn Hills in the set is a 1970 Dodge Challenger R/T in Plum Crazy, while Southfield's American Motors gets a nod with an AMC Javelin in Big Bad Orange. The Mustang's platform cousin, a 1967 Mercury Cougar XR-7, is portrayed in a gorgeous Burgundy Poly that almost looks incomplete without Neko Case on the hood. It's not the first time the USPS has honored America's rich car culture on its stamps. In 2013, it issues a series of muscle car stamps with the help of Richard Petty. That set featured a 1966 Pontiac GTO, 1967 Shelby GT-500, 1970 Chevelle SS, 1970 Plymouth Hemi ’Cuda and, of course, a 1969 Dodge Charger Daytona. Another set in 2016 featured classic pickup trucks. Going further back, a 2008 release had chroed and finned automobiles of the 1950s and a 2005 release featured sporty American cars of the same era. The pony car stamps will debut on August 25 at the Great American Stamp Show in Sacramento, California in partnership with the American Philatelic Society. The public is free to attend the dedication ceremony, but you must RSVP first. After that, they will be available at local post offices and on line at the USPS store.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.
