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.

Chevy rolls out Silverado HD High Country

It's been a good week for heavy-duty truck buyers. First, Ram revealed the Black Package for its HD trucks, then it rolled out its new Power Wagon, and now Chevy's getting in on the action with its Silverado High Country HD. Okay, so it may not pack quite the attitude of Ram's latest 2500-series offerings, but the High Country HD will come as a welcome addition to the Chevy Trucks range to those looking to pull their horse, boat or other trailer without skimping on creature comforts.
Rolled out a little under a year ago, the High Country trim is Chevy's answer to the likes of the GMC Denali, Ford King Ranch and Ram Longhorn. It has until now only been offered on the light duty, 1500-series Silverado, but now extends to the 2500 and 3500-series HD models, as well.
So what sets a High Country pickup apart from lesser Chevy trucks? You'll be able to pick it out based on its chrome horizontal grille, body-color bumpers, 6-inch tubular side steps, 20-inch chrome wheels (18-inch on the 3500 and 17-inch on the dualie) and, of course, plenty of special badging. But it's inside where the High Country makes its mark, with a cabin decked out in saddle brown perforated leather, seats that are both heated and cooled, eight-inch touchscreen with full MyLink suite, Bose audio and park assist functions front and rear to keep those color-keyed bumpers looking fresh. (Though Chevy hasn't yet showed us the interior of the HD model, it'll presumably look mostly the same as the cab in the 1500 High Country in the gallery below.)

Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.
