Most EVs offer cargo space that’s comparable to, or sometimes better than, a similarly sized gas vehicle, though how that space is arranged can differ in ways worth knowing before you pack for a long trip.
Why EV Cargo Space Is Laid Out Differently
Battery-electric vehicles don’t need an engine up front, which often frees up a front trunk, commonly called a “frunk,” as extra enclosed storage in addition to the rear cargo area. Plug-in hybrids still have a combustion engine, so this extra front storage generally isn’t available on PHEVs the way it is on all-electric models. The battery pack itself usually sits under the floor rather than intruding into the cargo area, so total cargo volume on most EVs holds up well against comparable gas models, though the shape and floor height can vary by design.
Roof Racks and Cargo Boxes Come With a Trade-Off
Adding a roof box or bike rack increases aerodynamic drag more noticeably on an EV than most drivers expect, and that translates directly into reduced highway range, sometimes a meaningful amount on a long trip. Our post on what affects EV range covers why highway speed and drag matter so much. If a trip requires more cargo capacity than the interior comfortably allows, it’s worth weighing a roof box’s range cost against simply packing lighter or splitting the load with a trailer, keeping in mind that towing capacity varies significantly by model.
What to Check Before You Pack
Cargo volume, frunk availability, and how much folding down the rear seats actually adds all vary meaningfully by model and trim, so it’s worth checking your specific vehicle’s published cargo specs rather than assuming based on its size class. A compact-looking EV can sometimes out-haul a larger vehicle simply due to how efficiently the space is arranged.
💡 Tip: If you’re planning to add a roof box or rack for a road trip, check our post on what affects EV range first, so you can build the extra charging time into your route plan rather than being surprised by it mid-trip.
