Big still beautiful to GM as it unveils new versions of SUVs

New Chevy Silverado & Tahoe

Despite America's growing desire to buy hybrids and fuel-efficient small cars and crossover utility vehicles, General Motors is betting many buyers still want big sport utility vehicles.

Thursday in Manhattan, the country's largest automaker took the wraps off of the new versions of its two most popular SUVs, the Chevy Suburban and Chevy Tahoe. The company also unveiled the new GMC Yukon SUVs, which will be built on the same platform as the Chevy SUVs.
