As a tradition, every Turbo car Porsche makes also gets a ‘S’ version. The differences are not subtle, in Panamera’s case it’s about 50 hp more power and slightly higher top speed. But you have to have the S because if you buy the normal turbo some day at the lights an S will pull up beside you and gives you a smug look that I’m better than you, and then you have to kill yourself! Here’s a new promo video of the Panamera Turbo S in some winding roads, reflecting on the joys of driving a 550 hp luxury GT.
