The prototype captured here on the Nurburgring wears a substantial amount of camouflage although the production version is unlikely to waiver from typical Saab styling.
These images also reveal the much shallower rear roofline, giving the new 9-5 a more coupe-like silhouette - with the car taking many of its styling cues from the 9-4X BioPower concept.
The new 9-5 is likely to gain some extra weight, with a greater length and height than the current model as well as a longer wheelbase, making it a closer competitor to models such as the Mercedes-Benz E-Class, Cadillac STS and Volvo S80.
The prototype in these images uses a turbocharged 2.0-litre petrol engine making 160kW, while a 2.8-litre V6 will be available in the European market with the US getting an even bigger 3.6-litre V6.
A diesel model is also a given along with a hybrid model, with its first public unveiling scheduled for the Frankfurt Motor Show in September.
