According to the luxury car maker, the new concept car will illustrate new design trends with bold and emotional execution.
The teased image shows a high hood line which is expected to preview a new Lexus SUV "coupe", that could rival BMW Group's Mini, and Audi A1.
The image also shows the lack of exterior side view mirrors which is similar to the LF-A concept debuted in 2004, reported Car and Driver.
The LF-SA concept is expected to go on sale in 2018, with production model only offering hybrid powertrain, reported Automotive News.
Lexus said: "In a future world which many people see as increasingly influenced by technology and virtual experiences, the LF-SA concept is also a driver-focused vehicle, reflecting Lexus' vision that real experience will remain ultimate luxury."
