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.

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 planning to put its fullsize pickups on a big diet, too

General Motors is just coming off a complete redesign of the Chevrolet Silverado and GMC Sierra for 2014, but in the US fullsize truck market, there is no rest for the weary. According to Reuters, plans are already unfurling for both trucks to drop pounds from their curb weight over the next few years, but this will unlikely be able to keep pace with the 700-pound diet targeted for the next-generation Ford F-150, a truck expected to debut late next year.
The biggest weight reduction for these trucks might not be available until the next full redesign, which will likely happen around 2019, but the article says that smaller updates could shave pounds in the meantime. Two examples given include an "aluminum-intensive" version of the Silverado that could shed 250 pounds and debut around the same time as the lighter-weight, aluminum-bodied 2015 Ford, and there is also talk of reducing weight for driveline components such as axles and driveshafts. These changes are all part of an attempt to meet strict new fuel economy standards coming in 2017, targets which will get even tougher in 2025.
