Only the aerodynamic design does not determine the performance of car, The engine and other devices (Legal and Illegal) also determine the performance. In 2014, the Ferrari SF14T had a much more aggressive design than Williams FW36 (which many people said it's just the FW35 adapted to the new rules). In addition, Ferrari had a better line-up than Williams (two world champions against two average drivers). Despite this, Williams finished ahead of Ferrari in constructors

SF14T was the infamous "aerodynamic perfomance first" car, which was designed keeping in mind the concept, that the 2014-spec cars perfomance would be depending more on the aerodynamic design and less on the PU design. It turned out that this concept was wrong. Williams beating Ferrari came down to the compatibility between the car design and Mercedes PU.
