The everyday supercar with the roof removed. The 911 Turbo S Cabriolet fires 640 HP through all four wheels for a 0–60 of 2.6 seconds and a 205 mph top speed — numbers that shame cars costing three times as much. Drop the roof and it becomes pure theatre: savage pace, total composure, and a finish that works as well on Sheikh Zayed Road as it does at the track.
