Engines tend to over-consume at very low speed and at very high speeds.
The optimum of specific consumption is at full load and mid-speed.
In summary, the engine gives you the most kWh per gram of fuel burned when you put it to 2000 / 3000 rpm and full air intake.
Hence the interest of a small engine running stationary at full load and mid-speed to recharge a battery pack.
The transmission of power to the wheels and its modulations is much better managed by an electromechanical chain.
