General Motors will unveil the all-new 2016 Chevrolet Volt plug-in hybrid at the North American International Auto Show in Detroit in January, but will there be a surprise behind the curtain with it when it does? This past August, the automaker applied for a trademark on the name Crossvolt, which was published for opposition on Dec 23rd. The filing offers no details as to what GM's intention for the name is, other than "automobiles."
