There are no details for the concept at this stage, although Lexus says the car will preview "a new design direction embraced by Lexus".
Lexus has released a teaser image to whet our appetites, revealing a complex collection of curves and corners that could belong to a new coupe - or even, dare we say it, a successor to the LFA supercar.
The concept could also offer a first look at a new third-generation IS sedan. That could be a stretch; any production version of this car is likely to be considerably more restrained than the detail of this image suggests..
As a preview of the carmaker's next styling evolution, we can likely expect to see a new take on the "spindle" grille design that has grown stronger with more recent Lexus releases - particularly on the all-new GS large sedan.
Watch for more details in the coming weeks.
