Fourth generation (GR, 2020-present) · Supermini / small MPV-hatchback
The Honda Jazz has 298 L of boot on the standard car and 304 L on the Crosstar. Its Magic Seats flip their bases up against the seatback, giving a tall, flat floor from footwell to boot that suits a bicycle or tall plants, so choose an organiser that is easy to take out when you need that space.
Sixth generation (RS, 2023-present) · Family SUV / D-segment 4x4
The sixth-generation Honda CR-V is a five-seater only in the UK, with 579 L of boot on the e:HEV AWD and 617 L on the 2WD. The rear bench slides fore and aft and reclines, so the boot figure depends on its position; size an organiser to where you leave the bench, and check its straps against the factory tie-down points.
Three products we would look at first in this category. Fit for your Honda still comes first: check the compatibility list on the listing against your exact model and year, and read the model guide above.
