Perhaps Chevrolet wanted to focus all its attention on its new Corvette, which will be unveiled at a special event on Sunday night, before the doors to the auto show open. Corvette only sold 14,132 units in 2012, but "anytime there's a new Corvette, it's a big deal," Hellwig said. "It's not a high volume car, but it's a halo car for GM and a showcase for GM technology. Everybody knows the Corvette name." Speaking to reporters, something he rarely does, at a gathering in Detroit on Wednesday, GM CEO Dan Akerson said of the new Corvette: "I think (it) will be one of the beautiful cars ever made."
