The new 9-5 will play an important role in moving the Saab brand forward under its new owners Koenigsegg which plans to complete its purchase of the brand from GM shortly.
"This car is the start of a new era for our brand," said Saab Managing Director Jan-Ake Jonsson.
“We have created an advanced and very distinctive product by leveraging the power of our roots in key areas, such as progressive Scandinavian design, sporty driving and responsible performance.
"The new 9-5 delivers in all these respects, as will every future product from Saab,” Mr Jonsson added.
Saab says the new 9-5 is the most technically advanced car it has yet made and offers an array of high-tech features including an aircraft-inspired head-up information display, Bi-Xenon adaptive headlights, adaptive cruise control, parking assistance and all-wheel-drive.
The car will be offered with petrol, diesel or E85 (bio-ethanol) four-cylinder turbocharged engines.
The new 9-5 shares GM's Epsilon 2 platform (think Opel Insignia), but the Saab version has a longer wheelbase and its own unique muscular, low-slung exterior styling and unique interior.
The current 9-5 has been on sale for 12 years and its sales have declined as the car has aged. Over the course of its life time the existing 9-5 sold 93,000 units globally.
Engine outputs and specifications for the new 9-5 are as follows:
The new 9-5 makes its public debut at the 2009 Frankfurt International Motor Show on September 15.
