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.

Are you the 2014 Corvette Grand Sport?

When are stripes more than just stripes? Follow up question: Is the product development team at Chevrolet really cocky enough to hide the next C7 Corvette variant in plain sight? This very recently spotted, and ostensibly obscured C7 asks a lot more questions than it answers, but there's at least some evidence to support that it might be the next Corvette Grand Sport.
The first and most obvious tip-off that something is up with this 'Vette revolves around those silver stripes. Obviously the stripes themselves don't necessarily denote a new model. However, when Chevy recently launched its "colorizer" website for the Stingray, there was no provision made for racing stripes - solid colors only.
Grand Sport exhibit number two is actually an incriminating lack of badges. The production Corvettes we've seen to date have all carried Stingray badges on their fenders, just behind the vent. The car seen in these images has no such badges, which is an intriguing omission on an car that looks like a production-spec vehicle otherwise.

Official USPS Muscle Cars stamps coming to a mailbox near you

As much as our digital lives have cut down on our trips to the post office, there are still times that sending "snail mail" is necessary. With us car lovers in mind and philately in their hearts, the good folks at the United States Postal Service will introduce a new stamp design called "Muscle Cars" starting on February 22.
Designed by artist Tom Fritz, the new collection of stamps consist of five classic muscle cars: 1969 Dodge Charger Daytona, 1970 Chevrolet Chevelle SS, 1967 Shelby GT-500, 1966 Pontiac GTO and 1970 Plymouth Hemi 'Cuda. In addition to just the stamps, the USPS is also commemorating the new series with plenty of collectable memorabilia. Previous car-related stamps include 50s Sporty Cars from 2005 and 50s Fins and Chrome from 2008.
