Set to compete with models such as the BMW 5-Series Touring and Audi A6 Avant the model is said to bring a 'distinctive, alternative choice to the premium large estate segment'.

The model features the same AeroX-inspired looks as the saloon and features an extended, falling roof-line which culminates in a steeply raked rear screen flanked by signature Saab ‘wraparound’ window glazing. 

'The launch of the 9-5 SportWagon is a much-awaited next step in the roll-out of our new product offensive,' said Saab Automobile CEO Jan Åke Jonsson. 'It will take Saab back into the large estate segment where we have established a strong presence in many key markets with our previous offering.'

Boot capacity details haven't been released but Saab says the SportWagon will feature an adaptable multi-fold floor, flexible U-rail load space configuration and under-floor stowage with a sealed wet storage compartment. A programmable, powered tailgate is also available.

The all-turbo petrol and diesel line-up will be the same as saloon and the model will also include features such as Saab's XWD all-wheel-drive system, DriveSense adaptive chassis control, adaptive cruise control (late 2012), Bi-Xenon SmartBeam adaptive lighting, keyless entry and starting, tri-zone air conditioning and a Head-up Display.

The model is available to order from the spring, with first customer deliveries to follow from September. Prices have not been announced.
