I have a question about the tense to use for the phrase "carry over". Suppose we are talking about a new model of some product:
Some of the features of the new model are/were carried over from the previous model.
Should the past tense or present tense be used? The past tense seems to be the right one, because the act of taking the features of the old model and putting them into the new model is one-time event during the product-design phase. But, a google search shows that the present tense is more common than the past tense. What do native speakers think?
