Beyond that, the luxury automaker has said precious little, leaving it open for us to speculate wildly about what this car might be.

A Japanese media report published around the time of the international LS launch indicated Lexus would pull the covers off a high performance variant, to be known as the LS F, at the Tokyo show.
Unlike the 3.5-litre twin-turbo V6 LS500 and the V6 Multi-Stage Hybrid LS500h, which we've driven and reviewed, the LS F will reportedly feature a twin-turbo V8 engine.
If this car shows up in the Japanese capital, it's unknown if it will be presented in production guise or as a concept car preview.

Should rumours and reports prove to be correct, the new ES will be based on the new front-wheel drive Toyota New Global Architecture, but will have sportier looks and disposition. In addition to replacing the current ES, the new car is thought to be a replacement for the GS sedan as well.
