2010 Porsche Panamera The moral of the story is simple. If you have a thoroughbred at your dispense you don’t walk it to the barn. You run it in the open! And that’s exactly what we did with Porsche’s all-new stable mate – call it the Panamera – on German’s infamous Autobahn. There, we were able to surpass 178 mph in the Turbo (a few mph shy of its top speed of 188 mph) all while our driving companion napped in the comfortable back seat. Yes, a Porsche sports car that seats four uncompromised! Welcome to the future ladies and gentlemen.
