Battery electric vehicles lose their spark in Europe as hybrids steal the show
Analysis of the average real-world fuel consumption and electric driving share of PHEVs in Europe, with an emphasis on WLTP type-approved vehicle models.
That’s news to me considering the EPA-rated fuel economy of vehicles with both hybrid and pure ICE drivetrains is universally higher for the hybrid versions.
An ICE vehicle needs a much larger engine than is truly necessary due to the inefficiencies and limitations of mechanical transmissions, whereas a hybrid can have a much smaller, more efficient engine.
A hybrid can potentially act like a ‘perfect’ transmission, capable of taking in power from an engine running at its single most efficient RPM and, with the aid of battery storage, produce any combination of speed and torque that has an average power less than the output of the ICE.
But it doesn’t. PHEVs can still regenerate during braking though. ICE only vehicles can cut fuel when off throttle, but that’s not going reclaim the heat lost to braking.
PHEVs should still be more efficient overall especially in cities and stop and go traffic.
If we had ICE only vehicles with tiny engines maybe your point could work, but we don’t anymore at least not in the US.

Because they make certain assumptions. Fortunately the EU mandated that cars measures those things since various years. That caused a review of those hybrids. They’re usually not charged.
Nothing in that comment discussed plugin hybrids though.
A non plug-in hybrid will be more efficient than a full gas vehicle because of the efficiency you can gain through minimizing the engine and tuning it for a more limited rpm range.
This ideally carries over to a plug-in hybrid in the same way even if it’s never plugged in, if all the gas engine does is charge the battery it can be more efficient than a gas only car due to reduced engine size requirements.
