It is a big issue for me here in sunny and sometimes hot New Mexico. Some normal auto's a/c cannot keep up with the temps. Porsche has a history of poor a/c performance, I guess because they don't face the same weather in Germany? I really don't understand how the heat is going to be removed from the cockpit and doubt that the a/c can keep up in extreme temps. That issue is my only concern and I too am looking for unbiased reporting on it.
