lol Andre, no one knows that my M5 has been bought back by the dealer, I am kinda in the middle now, either to buy 2013 M5 again or go family guy way and get a cayenne turbo. I'd hate to have Porsche again, but its the best offer on the table right now.
Is the Powerkit available yet? I think it will be the same as the Panamera Turbo Powerkit was: 540 hp and 800 Nm with Overboost. 0-200 km/h? The stock Cayenne Turbo with 500 hp managed 14,9 s in AutoZeitung's test, so...
DeDe, I went back to that thread, you were suspecting that the model under test was a powerkit one. The weird part is really a cayenne was keeping with me 100+ Km/h few weeks back ! I got surprised really.
