You can also look at the example given this way to make things more clear -
"small cars that are more fuel-efficient than they were ..."
"that are more fuel efficient than they were ..." is an essential modifier to small cars. (It is in this context that I meant same copy; sorry for the confusion)
So, 'they' does not seem to have a proper antecedent.
but otherwise, your examples seem fine as the pronoun refers to the general idea/thing.
