This is exactly what I am getting at. The small BEV uses less energy overall. But it seems less efficient in urban driving due to a smaller mass that results in a lower accelerating kinetic energy.

1) Please read #66 ( permalink )
2) Please do all the mathematics, then we'll discuss the results.
3) We'll do the hypotheticals after we have a clear numerical representation of the 2015 thesis quanta.

4) Less energy overall is what most impacts the life-cycle-cost to the consumer and planet.
5) After you have the BSFC-e for the Volvo, you'll be able to numericalize any delta- urban/ ' extra urban' cycle efficiency.
6) Your analysis of the 'penalty' of Inertia Resistance sets the stage for regenerative-braking energy capture contrast. Which I believe you'll find most interesting.
