While most hybrids are said to use one to two litres of fuel per 100km, a study claims they need six litres on average
Plug-in hybrid electric cars (PHEVs) use much more fuel on the road than officially stated by their manufacturers, a large-scale analysis of about a million vehicles of this type has shown.
The Fraunhofer Institute carried out what is thought to be the most comprehensive study of its kind to date, using the data transmitted wirelessly by PHEVs from a variety of manufacturers while they were on the road.
. . .
According to the study, the vehicles require on average six litres per 100km, or about 300%, more fuel to run than previously cited.
The scientists of the Fraunhofer Institute found that the main reason for the higher-than-stated fuel usage was due precisely to the fact that the PHEVs use two different modes, the electric engine and the combustion engine, switching between both. Until now it has been claimed by manufacturers that the vehicles used only a little or almost no fuel when in the electric mode. The studies showed that this was not in fact the case.
It depends on the use case, and they base thier claims on the best case scenario: living in flatland and only driving the EV only range most days.
I got 2l/100km fairly easily when most of my trips were just within the ev range, but when I moved to suburbia I got 5l/100km, while using less petrol in total(the shops I drove to were closer, so the trips to the shops had less effect on the average).
Makes sense to me. You include both a gas engine and everything needed to be an electric car with battery and the weight has increased a lot over just having one or the other.
Batteries are heavy and a hybrid doesn’t need very much battery because its gas tank is its real battery. If you’re planning to run EV-only, then buy an EV, that’s not the car’s fault.
This is because PHEV and hybrid in general use a gas motor to turn the wheels.
The solution is called EREVs Extended Range EV
A gas generator that kicks in when the batteries are low
Thats wrong. PHEVs only use an electric drive motor.
A gas generator that kicks in when the batteries are low
doesn’t fix anything
Also wrong. PHEVs still harvest energy from hills, coasting and braking, and the gas motors only run at one efficient speed and don’t idle.
Lemmy knows fuck all about cars.
Because the generator runs at its ideal RPM all the time, it can burn the fuel much more efficiently (and thus is slightly cleaner too). It’s the same as diesel-electric locomotives, which is like, all of the locomotives. So, it fixes a little tiny bit. Not enough, but every little bit helps.
It’s 60% less fuel use over a pure ICE car the same size.
