This is a working table of all unlock years for the various components in the game, without the use of techpool (which is used by car companies to unlock technologies earlier). Options unlocked beyond 2020 require techpool to use.
Items marked with an asterisk (*) denote options or revised unlock dates that are currently only available in the Light Campaign 4.3 open beta.
