will be very interesting a 3 month (or other duration) variables change... like real F1... not always motors are confident.... there are other choices, even price.
There are other choices but Power, Response, Economy, Rigidity & Weight are the main ones..
Cooling & Reliability don't seem to be in use at the moment, maybe they will be in play in later updates or I might not just be seeing them in action they maybe are doing something in the background.
Visual engine temperatures should be added to the car graphic in live race, So we can see the impact of weather temp & pushing to hard.
Could be similar to the tyres blue, grey & red.
Blue - under performing, lose of performance
Grey - optimise temp best performance
Red - over performing, lose of performance and may cause engine failure
