I'm a porsche fan, have owned many and still have one, but this is embarrassing. I bet a lot of people cancel their orders.
I can't imagine the range hit in the cold winter driving 75mph+. I bet the dealers are cringing as well. Imagine explaining to their customer that just dropped $200K+ that they should think of heat as optional in the winter if they have a 60-75 mile commute each way, a commute distance that is not uncommon on the east coast and in many other areas. And, with porsche's complete lack of charging network its all but rules out road trips.
Tesla should release the roadster ASAP, it will cost the same, have better performance and at a minimum double, up to triple, the range. That will make a statement and be an embarrassment to porsche.
So many of the "experts" keep talking about the competition, but this just proves there still isn't any.
