The triplets
Amid the hoopla of the three cars' debut, GM's vice chairman, Bob Lutz, called the concepts the "triplets." A troupe of dancers heralded the unveiling, and the audience was encouraged to throw colored balls--each corresponding to one of the cars--onto the stage to express a preference. Chevy is likewise encouraging people to vote for their favorite cars in an online poll.
