General Motors finally unveiled the redesigned Chevrolet Tahoe, Suburban and GMC Yukon variants. A 5.3-liter V-8 is standard in all but the Yukon Denali models, which get a 6.2-liter V-8 rated 420 horsepower and 460 pounds-feet of torque.
The new big SUVs will hit the showrooms in the first quarter of next year as 2015 models.
