Next-gen GM SUVs caught wearing new boxy bodies [w/video]

We recently drove the brand-new 2014 Chevrolet Silverado and found it to be vastly improved compared to the outgoing model. And now that The General's pickup trucks have been squared away, it's time to focus our attention onto their passenger-friendly companions, the Chevrolet Tahoe and GMC Yukon (above).
Our spy photographers have passed along a huge smattering of photos (and a video), showing the new SUVs out testing. Both the short- and long-wheelbase models were spied, and while the overall shape of the vehicles hasn't changed all that much, we expect the updates to be substantial. In addition to new powertrain options, like GM's new small-block V8, we expect the interiors of both SUVs to get massive makeovers, providing better materials throughout their cabins and quieter, more refined environments. We even hear that some trick new suspension developments may be in store for upper-end models.
Visually, these spy shots allow us to see a couple of new details on the SUVs' front and rear fascias, including LED running lamps on the Yukon and some interesting LED taillamp treatments. Of course, the obvious third party missing from this set of photos is the Cadillac Escalade, but as we reported earlier, GM is working to further differentiate the 'Slade from the rest of the fullsize SUV lineup, and is working to make the new model "much less ostentatious."

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.
