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.

Who sold the most heavy-duty pickups in 2012? PickupTrucks.com investigates

Domestic manufacturers enjoyed a good year for heavy-duty pickup sales in 2012. PickupTrucks.com has taken a close look at exactly how those sales broke down between each manufacturer and between three-quarter and one-ton pickups. Ford sold some 67,786 F-250 Super Duty models last year with the Chevrolet Silverado 2500 HD falling just behind at 56,359 units. The Ram 2500 HD came in third at 41,918, while the GMC Sierra 2500 HD earned itself fourth place with 27,616 deliveries. While Ford held onto the top spot in the one-ton market, Ram easily nailed down second place by selling more 3500 HD models last year than General Motors sold Silverado 3500 HD and Sierra 3500 HD trucks combined.
So, did GM manage to sell more trucks than Ford with its two brands? Very nearly. Ford sold a total of 119,338 heavy-duty pickups to GM's 111,555. Ram, meanwhile, moved a distant 77,583. But perhaps more interesting is the diesel take rate in this segment. PickupTrucks.com says 80 percent of all domestic one-ton trucks roll from the dealer lot with a turbo-diesel under the hood.

GM 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.
