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.

GM thinks Colorado and Canyon midsize trucks will lure crossover buyers

The invitation to come out and sample product at the General Motors Proving Grounds in Milford, MI is rarely dull, and after spending this morning driving preproduction versions of the Chevrolet Colorado and GMC Canyon all we can say is... under strict embargo. Sorry, America, we were as excited as many of you are to learn more about GM's new midsize truck range and take note of how they go down the road, but it's going to be September before we're allowed to share that with all of you. Here's to sweet suspense.
While we might not be able to talk about refinement or handling yet, we did find some of the product positioning and marketing statements from GMC and Chevy officials on hand at the program to be pretty interesting.
Of course, we all know that the literal competitive set for Canyon and Colorado is comprised of two comparatively ancient Japanese midsize trucks: the Toyota Tacoma (which currently owns this segment) and the Nissan Frontier. The Frontier's bones are as old as the 2005 model year, with 2009 marking the last time the truck was updated. The Taco was also launched in 2005, though it did see a freshening for 2012. The point remains that, in every facet from powertrain to dash plastics, the GM midsize truck twins are going to look positively space age by comparison when they hit the market for MY 2015.

GM confirms 2015 Silverado, Sierra to get 8-speed automatic

When viewed alongside the next Ford F-150 and the Ram 1500, there is one thing that seems to be missing from the Chevrolet Silverado and GMC Sierra. Where the F-150 will rely on turbocharging and aluminum architecture and the Ram sports an eight-speed automatic and an air suspension, the General Motors twins lack a big, calling-card feature. They're very good, very refined trucks, but one could argue that they're not terribly innovative.
And while it might not be as flashy a feature as air suspension or a lightweight skin, the Silverado and Sierra will get their own eight-speed automatic for 2015, a transmission that will be paired with the company's Ecotec3 6.2-liter V8. The new cogswapper will also find its way into the GMC Yukon Denali, but for now, there's no indication why the Cadillac Escalade, Suburban, Tahoe and standard Yukon are being left out.
According to GM, the new gearbox is about the same size and weight as the current Hydra-Matic 6L80 six-speed. By the time the new powertrain combination enters production late this year, the EPA will almost certainly have gotten around to certifying the vehicles' fuel efficiency. Until then, feel free to speculate. The current Silverado with the 6.2 and six-speed auto returns 14 miles per gallon in the city and 20 on the highway. How much do you think the eight-speed will improve those figures? Scroll down for the official press blast from General Motors, and then head into Comments.
