Ideas have been percolating.

A few questions.

-Generally, a large ICE running at low rpm uses more gas than a small ICE running in the BSFC sweet spot. Does this happen with electric motors as well? If I get a 25hp motor for the get-up-and-go, will it use more energy at a cruising speed than a, say, 15hp motor? I ask because perhaps the instant torque would allow the car to accelerate faster than a comparably powered ICE.

-I was planning on mounting an optional range extending single cylinder engine atop the rear wheel, behind the driver's head. This would allow it to drive for extended highway journeys (much like a Volt) instead of being limited by range. Let's say something like 150-200 mpg? A few days ago I learned about aptly named generator trailers. They haul the generator behind the vehicle, and while being better for packaging, they carry the obvious aero and RR penalty that will be hard to surmount in a car with such a small wake. Would the extra drag likely cancel out much of the vehicle's inherent efficiency?
