Lexus has announced that it will be premiering a new concept car at its Geneva 2015 stand this year. Absolutely no other details have been unveiled at this moment, but the automaker has shared a 3D floor plan of its stand. We’re guessing the concept is hidden behind the door next to the screen with the Lexus LFA.

So what could the carmaker be showing? There are many possibilities – some are speculating a bigger coupe than the RC, others say the fact that there’s an LFA on a screen indicates some kind of future LFA replacement. Another possibly is an “LF-RX” concept, which would preview the next-generation RX, said to be scheduled for a production unveiling in the second half of the year.

What do you think the new Lexus concept will be? Have a look at the gallery below for spyshots of a disguised next-generation RX prototype.
