Exactly why it's a given.
Very much doubt that they will replace the LC500 in Super GT, especially if an LC F is going to be brought to market. Also, considering the work done with the development of the RC F GT3, I doubt that the Supra will replace it. Maybe they will build GTE and GT4...
I really prefer their approach that makes proper F models of cars that make sense, rather than throwing the F at every car in the line up. That being said, an awd 2.0 Turbo hybrid CT F would have been nice.....
Commentators speaking at the end of the race spoke about the A90. Development car testing for motorsports suitability, possibly GT4, they said it was prepped in Cologne*
They seemed impressed by it's performance for what it is.
* Cologne/Koln is where TMG headquarters is located in Germany...
