That's correct , but its possible that the time has come when narrow-band-efficiency is an appropriate technology.
A "typical" car with a piston engine directly mechanically connected to the wheels needs an engine with a wide rpm and power output range.
A hybrid electric drivetrain doesn't necessarily need that - if a motor that could run at 60% efficiency but only at 8725 +- 15 rpm existed, it'd be useless for a traditional car, but it'd be easy to integrate that into a hybrid electric vehicle...
