It would be nice to have more than 25% solar>electricity conversion. It would be nice to have a fusion reaction that can harvest the energy in productive ways. Thorium might be a good bridge technology. The future will be amazingly unpredictable.

In order to understand the 'strange' behavior, requires an understanding of the proportionality between gains from regen, and losses due to inertial and rolling-resistance penalties.
For a delta-10% mass increase, the small suv experiences an 8.1% regen efficiency increase, while only a 1-2% loss to inertia and R-R, for a net gain of approx. 6.6%.
Aerodynamics does not participate.
