It's that time again - time to unveil our annual Top Picks, the best automotive choices in 10 different categories. Consumer Reports introduces our new Overall Score, incorporating not only road test results from our track, but also reliability, owner satisfaction, and safety scoring. We discuss the changes needed to do this, and what effect it will have on scores in the future. (Hint: They'll change a lot more often.) We then run through the Top Picks, discussing why each car earned its place on our list.
