Lorenzo, like his partner and stepbrother, is completely average in every aspect. He tends to whine and complain about almost everything, believing he can do better. Lorenzo's biggest rival was his stepbrother Chet, whom he became forced to live with after the marriage of their parents one year ago. Their parents decide to sign them up for the race as a last-ditch effort to inspire cooperation between the two. Despite being untalented, Lorenzo has confidence in himself in spades and fully intends to win the competition to humiliate his brother, Chet. As the race progresses, Lorenzo and Chet realize they have a lot in common and finally settle their differences, become good friends and accepting each other as stepbrothers and family.
