2014 Chevy Silverado High Country spied wearing trappings of new luxury trim

Spy photographers have spotted the new Chevrolet Silverado High Country and GMC Sierra Denali out on public streets for a little testing. From the looks of things, the Silverado will receive a much-differentiated front fascia along with special badges and those honking 20-inch chrome wheels. Expect to find a more posh interior as well. Likewise, the Sierra Denali will wear a tweaked nose with the familiar Denali bling. The one of the GMC trucks spotted here rolls on 21-inch gunmetal wheels instead of the 20-inch chrome pieces of the High Country.
Word has it both trucks will go on sale after the Texas State Fair this summer. While General Motors hasn't said for certain what we can expect to find under the hood, we'd be surprised to see anything outside of the range of engines found in the standard Silverado and Sierra models. That means buyers should be able to get their hands on the efficient, 23-miles per gallon 5.3-liter V8.

All of the Bond cars of 'No Time To Die' (caution for spoilers)

Note: The following overview of the cars in No Time To Die contains spoilers. Read at your own risk, or come back after seeing the film to make sure you caught everything.   No Time To Die picks up right around where Spectre leaves us. James Bond (Daniel Craig) and Madeleine Swann (Lea Seydoux) are driving along in Bond’s restored and iconic DB5 in Matera, Italy. Things donÂ’t stay all that cheery for long in picturesque Matera, though. As is tradition in Bond films, the first car chase hits us with an explosion of action in what's a super-long opening scene. Fourth-gen Maserati Quattroporte: The baddies in the beginning are driving a Maserati and chasing after Bond in the DB5. Specifically, theyÂ’re in a fourth-gen Quattroporte, which feels right for a chase scene in Italy. Its squared-off looks are mean enough, and its Italian growl is a good background soundtrack to the DB5Â’s inline-six. In addition to the Quattroporte, the chase scene in Matera is home to a couple of the best stunts of the entire movie, including the arch jump done with a Triumph motorcycle seen in trailers — Matera is extremely hilly. Eventually, Bond and Swann find themselves in the DB5 again together, which is where the famous gatling gun scene from the trailer commences, but not before the bulletproof windows and body of the DB5 are thoroughly tested. RIP to the first-gen Range Rover Classics and Jaguar XFs that joined the Maserati in pursuit of Bond (here's a list of other Bond cars over the years). As the DB5 escape scene concludes, we catch a glimpse of what appears to be a Ferrari from the 1970s. However, the view was far enough away that weÂ’ll need a second look to be sure of the exact model. Land Rover Series III: Next time we see Bond, heÂ’s fishing in Jamaica and driving around a blue Land Rover Series III. ItÂ’s yet another of the many Land Rover products featured throughout the film, and unlike most of BondÂ’s Aston Martins, this one doesnÂ’t seem to have any unique features. The other intriguing vehicle out of Jamaica? An old Chevrolet Bel-Air expertly and effectively piloted by Bond newcomer, Ana de Armas. Next up, we get a few shots of the new and still-not-for-sale Aston Martin Valhalla mid-engine supercar (also seen in trailers). BondÂ’s old boss M is in the scene which appears to have been shot in some secret wind tunnel of sorts. Much to our dismay, nobody ends up driving the Valhalla in the film. Could it be a teaser for what the next 007Â’s car is?

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.
