The new Insight includes Honda's fifth generation of its Integrated Motor Assist (IMA) hybrid system. This system mates an internal combustion engine with an electric motor mounted directly to the engine's crankshaft between the engine and transmission. Honda states that this configuration is less complex, lower cost, and compact enough to accommodate a wide range of vehicle sizes when compared to competing hybrid powertrains. Honda has used previous generations of this IMA system on all of its production hybrid vehicles including the original Insight, Civic Hybrid, and Accord Hybrid. Advanced development has allowed the Insight's IMA system to be 19 percent smaller and 28 percent lighter than the previous generation IMA used in the existing Civic Hybrid.
