Essentially a convertible version of the GT 86 coupe, the Open Concept features a multi-layered canvas hood incorporating a glass rear window.
This folds electronically behind the fixed rear seats, and the 2+2 seating layout remains.
The show car offers a bright white exterior and contrasting navy blue canvas roof. On the inside, bright white seats are held together by yellow stitching to match the yellow carpets.
The Open Concept uses the 197bhp 2.0-litre four-cylinder boxer engine from the coupe – the reigning Auto Express Performance Car of the Year.
Toyota says the GT 86 coupe was designed from the start to be easily converted to a soft-top, and that the amount of engineering to add a cabrio to the line-up “is not expected to be great”.
