#1 - Ferrari (16)
Who else could've been but these guys? Ferrari have been a part of Formula 1 since day 1, entering the championship in all of its 69 seasons of existence.
Their first driver's title came in just the third season, Alberto Ascari triumphing in 1952, but the constructor's championship wouldn't arrive until to 1958. Phil Hill became the first of three men with that surname to win the driver's and constructor's championship with Ferrari, and since then, 15 more followed, with legends such as John Surtees, Niki Lauda, Jody Scheckter, Gilles Villeneuve, Kimi Raikkonen and of course, Michael Schumacher.
They are the most successful team of all time in every category, championships, wins, podiums, poles etc... and have also been Mercedes' closest challenge in recent seasons and have the best chance of them knocking the silver arrows off their golden perch.
