Employing next-generation Integrated Motor Assist (IMA) technology, the 2006 Honda Civic Hybrid is more powerful, more fuel efficient, and meets strict AT-PZEV Tier 2 Bin 2 emissions regulations. Honda claims this IMA system can motor along on the batteries under certain low-load, steady state cruising conditions. We managed a 47.1-mpg average in a drive that covered two-lane country road, an 80-mph blitz down the freeway, and rush hour city driving.
