“ The researchers attributed most of the gap to overestimates of the “utility factor” – the ratio of miles travelled in electric mode to the total miles travelled – finding that 27% of driving was done in electric mode even though official estimates assumed 84%. ”
Perhaps the rav4 prime @ 41ml max ev range is a better system than all the other low range PHEVs like it, and has better real world usage data than them. I doubt it though, but I don’t have the data on just the rav.
So if you are too lazy to plug it in every night or your day to day driving exceeds the battery range you shouldn't buy one.
One of my neighbours has one but nowhere to plug it in. I have no idea why they bought it.
This wouldn't stop me from buying one.
0 mention of rav4 in this article which seems to be about European cars.
European registered cars. The RAV4 PHEV is a popular car in Europe so is assuredly well represented in this data set of 800,000 phevs.
It's an interesting article - thanks for sharing! The original report is worth reading too. [1]
I agree with the premise. The "utility factor" used to estimate fuel efficiency for PHEVs does not line up with real-world data, which effectively creates a loophole to avoid emissions regulations and keep selling gas guzzlers. This is a problem, and should be fixed.
In regards to which cars are most to blame:
> Volkswagen, Mercedes-Benz and BMW account for the lion’s share of fines avoided over the past three years, together responsible for 89% of the total.
This is a recent trend where luxury carmakers are using PHEVs to circumvent emissions regulations. The latest BMW M5 [2], for example, is a PHEV with a monster 4.4L V8 engine. Car enthusiasts actually hate it compared to the old model because the hybrid system increased the weight by 1000 lbs. But making it a PHEV is probably the only way that BMW is still able to sell a V8. It seems kind of stupid all around.
The RAV4 PHEV is also a big, heavy (4,500 lb) car with a large (by European standards) 2.5L engine. But I would hesitate to lump it in with luxury cars from BMW, Mercedes, Land Rover, etc. I would also hesitate to apply findings from a European study to the US market, where large gasoline cars are currently very popular (not that every discussion needs to be about the US - but the RAV4 is the best selling car in the US so it's important to that market). Not saying you're wrong about RAV4 PHEV emissions relative to the gasoline RAV4, just that the study you linked doesn't really support making any specific claims about that model. The report only mentions Toyota once, where it is lumped into an "others" category on a chart along with Ford, Hyundai, JLR, Kia, Mazda, Mitsubishi, Nissan, and Suzuki.
