Yeah I'm not sure on best sellers, but that Cayenne came as a lifesaver for Porsche. Who thought in 2020 a luxury SUV from a sports car brand would become the most popular model and save the company
Actually, the Panamera has never been as popular as the Cayenne in Europe. The Cayenne averages at +10K a year since 2003, while the Panamera only reached once 10K of sales a year, in 2017. The Macan has been an even bigger success, with most years passing 20K of sold cars per year in Europe. On average, the 911 was selling easier than the Panamera.
