What is the boot capacity of the Lexus UX 300h?

The boot capacity of the Lexus UX 300h varies by market and rear-seat configuration. In the United States, you get about 21.7 cubic feet (614 liters) behind the rear seats, expanding to about 41.0 cubic feet (1,161 liters) with the rear seats folded. In Europe and other markets, Lexus lists about 320 liters (11.3 cubic feet) with the rear seats up, and roughly 1,100–1,200 liters (38.8–42.5 cubic feet) when the rear seats are folded.


Market-specific cargo space


Below are the official cargo figures by market, illustrating how space changes when you fold the rear seats.



  • United States (UX 300h): 21.7 cubic feet (614 liters) behind the rear seats; 41.0 cubic feet (1,161 liters) with the rear seats folded.

  • Europe and other markets: 320 liters behind the rear seats; approximately 1,100–1,200 liters (38.8–42.5 cubic feet) with the rear seats folded.


These figures reflect standard configurations and assume the typical 60/40 split rear seats where available. Exact cargo volume can vary slightly by trim level, optional equipment, and measurement conventions used by different regions.


Notes on measurements and practical considerations


Boot measurements are published in liters for Europe and in cubic feet for the U.S., with rear seats up and then folded to show maximum cargo capacity. The UX 300h’s compact footprint means the boot is modest for a crossover, but folding the rear seats significantly increases usable space for luggage, groceries, or longer items.


Summary


For buyers evaluating cargo space, the UX 300h offers a European spec of about 320 liters with the rear seats up and roughly 1,100–1,200 liters with seats folded. In the U.S., the figure is about 21.7 cubic feet behind the rear seats and around 41.0 cubic feet with the rear seats folded. Always check the local spec sheet for the exact numbers tied to your market and trim.
