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.

GM will no longer remove parts from trucks to calculate curb weights

Following last week's mild uproar after it was discovered that Ford and General Motors were removing some optional parts from their pickups to lower the curb weight and consequently increase the maximum payload, GM has come out and committed to a base curb weight for its upcoming Chevrolet Colorado and GMC Canyon compact trucks (although it has yet to publish them) and its current Silverado and Sierra. The company will do the same for its heavy duty offerings, although those numbers have not been finalized yet.
"This will make our curb weight and payload specs more consistent with those of most other truck makers, making it easier for customers to compare vehicles," GM spokesman Tom Wilkinson told Autoblog in an emailed statement.
As GM notes - and as every manufacturer has noted since this story broke - customers still shouldn't take max payload ratings as gospel. Instead, they should refer to their truck's Tire and Load Label, like the one shown at the inset, which will offer detailed information on max payload, specific to their truck.

2015 GMC Canyon is a Chevy Colorado in Sierra clothing [w/video]

Ford may not offer the Ranger in America anymore, nor Dodge (or Ram) its Dakota. But General Motors - not unlike Toyota with its Tacoma and Nissan with the Frontier - isn't about to give up on the midsize pickup market. Less than two months ago, it revealed the new Chevrolet Colorado, and now it's following up with its mechanical twin, the 2015 GMC Canyon.
Launched today ahead of its reveal at the Detroit Auto Show, the Canyon slots into the GMC lineup (and differentiates itself from its Chevrolet twin) with styling that closely apes the larger GMC Sierra 1500 and Sierra HD, only a size or two smaller. Oh, there are visual differences, like a subtly different grille treatment and lower fascia, but it still maintains its big brother's square-jawed good looks and rectilinear flared fenders.
Two aluminum-block engines with direct injection and variable valve timing are available: a 2.5-liter inline-four comes standard with 193 horsepower and 184 pound-feet of torque, and a 3.6-liter V6 is available with 302 hp and 270 lb-ft. Buyers will also be able to choose between three bodystyle configurations, three trim levels and either two- or four-wheel drive. A six-speed automatic transmits the power to the road, but a six-speed manual is available on the base model with the 2.5 and 2WD, and there's an All Terrain package available on SLE models. A diesel is expected later.
