Series Hybrids
This type is less common, but it’s more popular now. These also use a primary drive motor that propels the vehicle using regen-collected battery energy at low speeds and scavenges energy when slowing.
Once speeds climb and that energy runs low, the engine switches on to drive a second dedicated generator that turns gasoline power into electricity to keep the battery fed.
This means their wheels are electrically driven at all speeds, so power delivery always feels smooth and seamless. The downside is that converting gasoline into electricity represents an extra step that reduces efficiency, but newer approaches make this less significant. Honda is the most recent champion of this type, which powers the latest iterations of the Civic, CR-V, and Accord hybrids.
