The Civic hybrid has a 20 kW battery that weighs 48 lbs according to Honda. That comes out to 2.4 lbs/kW. The battery in the current Civic hybrid is significantly lighter, smaller and has a longer range than the old hybrid version.
I would agree that it completely depends on what kind of hybrid system Toyota would want to put in the FT-86/FRS.
