It's purely because the car was already winnable in a previous event. It's for the reason already mentioned above, FM doesn't want players to win the car with a set of upgrades, then be able to complete the new LTS with those same upgrades.

It's not just the MP4/4 either. The Agera R and MP4-X will also require more than 3's in their LTS's in this update as well. Only the new cars with LTS's require all 3's to complete their LTS's (at least in this update).

On a related note, SE's can be repeated, coming back as Flashbacks, but LTS's are basically never repeated (though the Corvette C7.R LTS was run twice, but the rewards were reduced the 2nd time, though the required PR remained the same).
