When it comes down to it, I think the NSX would suffer if it had IMA. Added weight, more electronics than machine, and does anyone know what type of tollerances electric motors need for reliable high rpm abuse? I'm not saying Honda couldn't do it..... I know they can. But the extreme heat and high rpm running require much more engineering than that in a Civic Hybrid or Insight. The price difference could shoot it into real exotic territory (> $150,000). Do we really want the NSX to deviate so far from its roots?
