That's the inefficient approach.
In a vehicle like the Zing, it'd mean the engine would be unnecessarily bigger, which makes it less efficient and in turn negatively affects vehicle weight, complexity, and size.
It's the main problem of the Volt / Ampera.
The very small generator approach is the best range-extender option as it doesn't add too much unnecessary stuff because it's still driving the vehicle using its intended, optimised electrical drive train, only putting out the lowly average load while not being sized for the peak loads.
