			It would be nice if, rather than the car be one chassis that accepts different components, it was a family of subassemblies that all came together to make a car. For example, four "suspension" subassemblies could be bolted onto a [[Power Cube]] to make a 4-wheeler, or the same four "suspension" subassemblies could be bolted onto a couple Power Cubes and a cabin to make a car, or even bolted onto a flatbed to make a light pickup truck.

	The current plan is for the car to be a reverse trike with two wheels up front and one wheel in back. The benefits to a reverse trike are: less weight due to one less wheel, less variable cost due to one less wheel, and better aerodynamics due to the tapered rear end that can be achieved. Federal regulation requirements are much less onerous for a three-wheeled car than a conventional car which allows for a much lower cost to develop the vehicle. Many state regulations might also be avoided since many/most states treat a three-wheeled vehicle as a motorcycle (Need to research this.) Using a three-wheel design would allow for the back wheel to be directly driven which would obviate a differential, shafts, etc. See the Aptera for an example of a car with a shape that fully exploits the reverse trike configuration: www.aptera.com.
