GMC, which markets only pickups and SUVs, was one of only four brands to survive General Motors' 2009 bankruptcy restructuring. Because all of its models are based on Chevrolets, GMC found itself on the chopping block until GM showed the division's financials to President Obama's Automotive Task Force, and the brand was saved. Simply put, it makes money. GM says the brand's "Professional Grade" image appeals to different buyers than Chevrolet attracts, and if GMC models were discontinued, their buyers wouldn't necessarily buy Chevys instead.All of the GMCs offer more power, more features or more luxury than their Chevrolet counterparts, or some combination thereof. The GMC Terrain compact crossover is based on the Chevy Equinox. The Canyon compact pickup truck comes from the Chevy Colorado. The GMC Acadia crossover, with up to eight seats in three rows, is related to the Chevy Traverse. The GMC Sierra pickup truck lineup is based on the Chevy Silverado. The Yukon and Yukon XL full-size SUVs are based on the Chevy Tahoe and Suburban, respectively. The Yukon is available as a hybrid. GMC also markets the Savana cargo van, based on the Chevy Express.In the wake of its bankruptcy, and pending an initial public offering of stock, GM is privately held predominantly by the U.S. Treasury, which owns more than 60 percent. The Canadian government owns roughly 12 percent, and bondholders from the now-defunct GM (Motors Liquidation Co.) hold about 10 percent. More than 17 percent belongs to a United Auto Workers health care and pension trust that the union accepted in lieu of earlier cash commitments. The UAW will sell its interest to fund the trust once the company goes public.
