Plug-in hybrids get plugged in more than you might think

But only if you plug it in\. And it is[often taken](https://www.caranddriver.com/features/a70290432/never-charge-plug-in-hybrid-what-happens/)as a statement of fact that plug\-in hybrid owners don’t plug in their plug\-in hybrids\. Instead, they were seduced into buying a car with far too big a battery, no doubt as a result of[generous incentives](https://arstechnica.com/cars/2023/04/these-10-evs-and-plug-in-hybrids-still-get-the-full-7500-tax-credit/), the theory goes\. And if those drivers aren’t going to plug in and therefore enjoy at least some entirely electric driving, they should have bought a parallel hybrid instead, which often delivers better efficiency than a PHEV with an empty battery, at a significantly lower price\. But what if that take is wrong? As it turns out, there’s some more evidence that PHEV drivers do in fact plug in their plug\-ins, and the latest data point is from one of the most prolific PHEV pushers: Toyota\. In the past, Toyota has[declined to provide numbers](https://insideevs.com/features/727919/phev-plugged-in-user-data/)when asked by journalists about the frequency of PHEV plugging\. But a pair of researchers at Toyota Research Institute North America have now[crunched some data](https://saemobilus.sae.org/papers/identifying-patterns-real-world-charging-frequency-a-sample-plug-hybrid-electric-vehicles-north-america-2026-01-0429), and, after looking at anonymized data from more than 6,000[RAV4 Prime](https://arstechnica.com/cars/2021/11/the-toyota-rav4-prime-is-a-pleasing-plug-in-hybrid-suv/)and[Lexus NX 450h\+](https://arstechnica.com/cars/2024/09/lexus-at-its-peak-the-2024-rx450h-is-one-smooth-plug-in-hybrid/)\(between model years 2021–2024\), the results are encouraging\.
