It all depends on what the ICE engine is designed to do. An BMW i3 with a 3 cyl engine and maybe 4 gallons of gas and a 35 MPG ICE if far different from a Prius Plus (the plug in Prius) or the Porsche racecars.
The Panorama Hybrid actually ended up in Motor Trend's top 6 sedans for 2018. Go look at its stats. The Boxster/Cayman didn't. (They tested the S and balked at the price and made the usual engine sound comments.)
