Initially, the 2006 Honda Civic Hybrid will get noticed if for no other reason that its shape is a dramatic departure from the staid three-box look of the current model. But once Honda sells its planned 160,000 DX, LX, and EX gas-engine sedans during the first year of production, the new Civic Hybrid will fade into the background. Differences between it and the “regular” sedans are limited to a subtle lip spoiler on the trunk, flat-faced alloy wheels that look like punctured pie tins, turn signals embedded in the sideview mirrors, clear front turn signal lenses, and a micro antenna affixed to the trailing edge of the roof. Oh, and it says “Hybrid” on the back.
