How big is the trunk of the Lexus NX 350h?
The trunk behind the NX 350h’s rear seats holds about 16.7 cubic feet of cargo space, with roughly 53.7 cubic feet available when the second row is folded flat. These figures reflect the current-generation NX (introduced for the 2022 model year) and can vary slightly by year and trim depending on floor configuration and whether a spare tire kit is included.
In practical terms, that space supports multiple suitcases and grocery runs for most families, while the expanded setup suits longer items such as camping gear or a set of skis when the rear seats are down.
Cargo space measurements
Exact figures for the NX 350h typically show 16.7 cubic feet of space behind the rear seats, increasing to about 53.7 cubic feet with the second row folded. In metric terms, that’s roughly 473 liters behind the seats and about 1,520 liters with the seats down. Note that these numbers can vary slightly by model year and trim due to the arrangement of underfloor storage or the presence of a spare tire kit.
What affects cargo capacity
Two main factors can influence usable trunk space: the presence of an underfloor storage compartment and the spare tire kit. Some trims place tools or a temporary spare under the floor, which can slightly reduce load height or floor depth but keeps the overall cubic capacity similar. If a repair kit is installed instead of a full spare, the floor may be flatter and the usable height higher, affecting ankle clearance but not materially changing volume.
Practical takeaways for buyers
For everyday use, expect to fit two large suitcases or several grocery bags in the NX 350h with the rear seats up. For larger items like a couple of mountain bikes or long boards, folding the rear bench is typically sufficient, though you’ll want to measure any particularly long items to ensure a comfortable fit. If you frequently haul bulky cargo, test fitting in person is recommended because the floor height and boot opening width can influence ease of loading.
Bottom line
The Lexus NX 350h offers about 16.7 cubic feet of trunk space behind the rear seats, expanding to around 53.7 cubic feet with the seats folded. The numbers are consistent across recent model years, with minor differences arising from trim, spare tire configuration, and underfloor storage choices.
Summary: The NX 350h provides roughly 17 cubic feet of space behind the back seats and about 54 cubic feet when the rear seat is folded, making it a practical choice for everyday hauling with some flexibility for larger items depending on year and configuration.
