That is definitely an improvement
So the strategy around town at this point is to accelerate with heavy throttle AND echarger? thereby nullifying the "cost" of having the electric motor turning the engine while keeping the engine in decent bsfc, but resulting in rapid acceleration?
The only question I would have then would be how much more difficult would it be to drive a wheel and what would an optimized strategy yield in mpg improvement there? How about an e-wheel that you can raise on demand as a possible next step?
