I don't think they will. If an engine is smaller than a Miniature Live steam engine, then they cannot be Sentient. Point is, you won't want your toy cars to be alive, wouldn't you?

For me, if a vehicle is unpowered and it's not a piece of rolling stock, it cannot be sentient. If it's powered and can carry people, it can be sentient, but powered vehicles that cannot carry people (Such as Mowers, Model trains and RC Cars) cannot be sentient. Cranes, Owen, Annie, Clarabel, Henrietta, Judy, Jerome, Rocky, Toad, Bradford and the Troublesome trucks are exceptions to these of course.
