Sebastian Vettel is a strong believer in imitation being the sincerest form of flattery after seeing a number of Ferrari design elements pop up on rival cars this year.
After going 20 races without a victory in 2016, Ferrari turned its fortunes around over the winter and under 2017's new technical regulations delivered a car capable of winning four of the opening 11 races this season. Vettel went into F1's summer break with a 14-point lead over title rival Lewis Hamilton after claiming victory at the Hungarian Grand Prix last month and says Ferrari should be proud of what it has achieved so far this year.
