Im with you 100% on the get rid of the throttle/pumping losses, but I have yet to see anything that approaches 98% efficiency in terms of cvt or "electric transmission" under a wide range of vehicle speeds.
Not to totally hijack here, just wondering if there is a source (link) that someone has actually solved the myriad number of issues with %98 efficient transformation/storage of power to keep the engine happy under a wide range of vehicle speeds and loads.
My beef is that the engine being at/near happy bsfc in this scenario seems to require a vaporware transmission and storage scheme (vs an honest to goodness real driver).
