The Mk4 Jazz (GR, 2020-onwards) is UK-hybrid-only, and its signature feature is the Magic Seats bench: the rear seat bases flip UP against the seatback cinema-style, giving a tall flat cabin floor from footwell to boot. That trick works only if the rear floor is clear - a rear liner that wraps up the seat base defeats the flip.
The standard Jazz has a bare roof and sits at normal ride height. The Crosstar variant adds factory roof rails and sits 30 mm higher; that changes the sill height and rocker panel geometry, but the passenger cabin footwells are identical between them. Same front and rear mats fit either body.
Trim variance is minor here - Elegance, Advance and the Crosstar Advance share the same seat rails and floor pan. Nothing about the trim badge affects mat fit; the only real check is that the mat set is Mk4-specific and not left-over Mk3 stock, since Honda’s floor hook pattern changed between generations.
Frequently asked questions
Do the standard Jazz and Crosstar share the same floor mats?
Yes. Both share the GR platform footwell, seat rails and retention hooks. Only the ride height and roof rails differ.
Will a rear liner block the Magic Seats mechanism?
If the liner is flat and does not wrap up the seat base, no. If it has a raised rear edge that follows the seat base contour, then flipping the base up rolls the liner forward. Buy a flat rear liner for Jazz specifically, not a generic “raised-edge” one.
