400hp V6 using E85 and lambo sort of doors and most likely awd, thats pretty much all is known.
Saab concepts have usually been quite good when it comes to looks and realistic.
What comes to Saab customers they are desperate for more sporty cars, like 2-seater ones. Turbo technology changed core customer base to be more performance oriented than it used to be. Less tweed professors and more younger high educated people, mostly engineers.
Sadly Saab needs to focus its bread and butter cars first, next 9-5, crossover, entry model and that sort of things.
After those are pretty much rolling then comes time and money for "halo" car.
Expectations for this car are of course enormous from everyone. Most likely it will meet majority of these.
