Every once and a while an automaker takes the steps to trademark a name that may be used for products or models without giving details about its actual future. Sometimes the names turn out to be a large part of the brand's upcoming plans, but other times, they don't get used at all. With this in mind, it's hard to say what Chevy was thinking when they recently decided to trademark the names 'Chevrolet Bolt' and 'Bolt,' which are surprisingly similar to their 'Volt' trademark. Filed to be used as car names, they stir up a lot of speculation as to what Chevy's future plans entail, but as of now, they remain a mystery.
