GM 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.

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.

Mysterious white powder discovered at GM Orion Assembly

Workers at General Motors Orion Assembly Plant in Orion Township, MI uncovered a mysterious white powder in two different parts of the factory earlier this week, raising concerns about worker safety. "We can confirm that an unknown substance (white powder) was found on the floor outside of Gate 6 at Orion Assembly on Monday, August 29. On Tuesday, August 30, we had a second report of a bottle containing a similar substance found inside the plant," GM spokesperson Dayna Hart told The Oakland Press via email. GM stressed that incident didn't disrupt operations at the plant, and that the company was taking steps to ensure the safety of the sprawling factory's workers. That did include, an anonymous worker told The Oakland Press, closing off parts of the factory for two full days, as drug-sniffing dogs and crews in haz-mat suits descended on the area. "A sample of the substance has been sent to a laboratory for identification and results are expected later this week," Hart said. "All findings and actions have been shared with our employees." Orion Assembly currently builds the Chevrolet Sonic and Buick Verano, and will eventually be responsible for production of the new, all-electric Chevy Bolt early next year. Related Video:
