The 2013 Buick Verano Turbo is a premium compact car with a dirty little secret: it's fast. Buick does let on that the nicest, newest version of its smallest car has a version of the Regal GS's turbo four cylinder and that it will go from zero to sixty in 6.2 seconds. But the brand is bashful, if not quite embarrassed about all this. "I don't think want to play in the 'GS' space with this car," warns Verano chief engineer Gary Altman. "I don't think the customer is looking for it."
