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

Plug\-in hybrid powertrains were developed to be the best of both worlds: a combustion engine and fuel tank that can handle those longer journeys exactly the same as a non\-hybrid car, with an electric motor and a battery large enough for most or all of someone’s daily driving range\. 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\.
Audi's new RS5 is a plug-in hybrid performance car with a new electric torque-vectoring rear differential, combining a turbo V6 and electric motor for 502 hp and 50 miles of electric range.
Honda announced plans to launch 15 new hybrid models by 2030 in North America, targeting a 10% increase in fuel efficiency and 30% cost reduction, while absorbing a $9 billion loss from its EV business and converting US factories for hybrid production.
This article explains in depth the core value of hybrid cars: it is not the battery and electric motor themselves, but rather how they make the Atkinson cycle engine—which normally has poor low-end torque—practical, thereby significantly reducing fuel consumption. Taking the 2021 Toyota Sienna as an example, it elaborates on how the hybrid system achieves excellent fuel economy without compromising driving experience.
US automakers like Ford and GM are pivoting from struggling EV programs to battery energy storage systems, repurposing plants and forming partnerships to supply utilities and data centers, with Ford's new Ford Energy subsidiary driving a 13% stock surge.
GM announces that 12 of its EV models now support bidirectional charging, enabling owners to power their homes and sell excess energy back to the grid, though adoption requires costly hardware and utility partnerships.
