Did Ferrari and McLaren decide that a N/A engine with electric motors unfeasible?

If I read the quote from Porsche engineers correctly, a combination of N/A engine and electric motors would require a smaller and reduced hp engine. With the smaller engine and additional weight, wouldn't acceleration and sound be impacted? Maybe Nick can chime in and tell us what it is like with his 918.
