Probably the ones with the shortest head tubes that place the bars lower and rider in the most aerodynamic position (i.e., a true flat-bar road bike). The 2010 Fuji Absolute fits this description but I don't know if there are any of these left. Most people buy hybrids for a more comfortable/relaxed position compared to a road racing bike.

Generally speaking, if the stock manufacturer's photo shows the bars level with the seat it's probably designed to be fast. Gearing doesn't really matter IMO as long as there's a double or triple crank.
