Real-world CO2 emissions of cars are 20% higher than indicated. For plug-in hybrids they are 350% higher.

It’s not a tupi; plug hybrids are used in real word cases with ICE much more than anticipated. In the EU, fuel consumption monitoring devices are required on new cars. They studied over 10% of all cars sold in 2021 and turns out they use way more fuel, and generate way more CO2, than anybody thought. The gap means that CO2 emissions reduction objectives from transport will be more difficult to reach. Thruth is, we need less cars, not “better” cars.

Seems to be a repeat of the misleading (and outright cheating) scam that diesel emissions turned out to be, although presumably not quite as egregious as what VW did. Although presumably part of the hybrid problem is that people aren’t actually charging them electrically most of the time.

TBH, the most astonishing reveal from the study for me was that Hybrid owners weren’t charging their vehicles. Unfortunately, the why isn’t covered in the study since it seems to just be hard math and statistical analysis.

Are they just not plugging in at night?

Too frustrated with the battery draining too quickly?

Driving too far for the battery to meaningfully contribute between charges?

Is the extra hardware mass making the ICE that much less efficient?

Laziness from having to fill both the battery and the gas tank?

I think this is the real question. From the stats you posted, I’d say that at most 10% of Plugin hybrid owners charge their vehicles.

Which is such a waste of ressources. Why does someone buy a car with 10 kWh battery and never even use it (beyond what the car charges itself)?

Especially given how much more expensive they are than conventional hybrids and the hoops you have to jump through to even grt one in my family’s experience.

The small battery capacity they have also means that any household outlet will charge them fine, so it would be really interesting to see why people are going through all the extra effort to buy one and then not use it.
