Misleading article. Someone reading this may think that a PHEV will have higher fuel consumption than claimed. When it reality it should be clarified that fuel efficiency is based on roughly 75% electric drive share.

I see the point where they should adjust that down based on real.world usage.

But… if you are expected to drive 75% electric based on battery range and your usage, you will hit the manufacturers claims, give or take

How is it misleading?

Manufacturers make claims about fuel consumption. Based on studying real-world data, fuel consumption is significantly worse than claimed. The study authors say that internal combustion engines are active much more frequently than claimed. They propose that manufacturers and regulators use real-world data because it’s more accurate. Is that such a bad idea?

plug in hybrids are impossible to properly quantity fuel usage. because unlike normal cars where you estimate highway/urban use, now you have to also consider EV/ICE use.

if you rarely use the engine, then your fuel usage is negligible. while if you mostly drive it like s hybrid and never charge it, it’ll be just as good as a comparable hybrid.

Statistics exist, taking a sample of thousands of PHEV drivers and examining fuel consumption is exactly what we can do to quantify fuel usage. And the reality is that, on average, they use up more fuel than my 2006 diesel I got for 2000€. For the vast majority of people, PHEV are just a scam

acreage is meant to give you an estimate of how much is it going to cost you, if it is off by 20% based on you doing now highway than the average, that’s fine.

but if it’s off by 100%? that’s useless.

also, averages only works if the data falls under a normal distribution. if you have people charging their cars at night, and others who don’t, that is not a normal distribution amd averages are useless
