These new photos show additional details about the car's exterior and interior design.

Several new high quality photos of Saab's upcoming 2010 9-5 sedan have surfaced.

Like the first batch of leaked photos, these new images show additional details about the car's design. The 9-5 features unique exterior mirrors which consist of three different sections: body color, integrated LED turn signals, and blackened upper trim (like the A-pillars). Other interesting design traits include chrome detailing on the lower front quarter panels and attractive LED taillights.

Inside, the cabin appears tastefully decorated with high quality plastics, a center console-mounted ignition, and aggressively bolstered leather seats. This adds up to a cockpit that is easily recognizable as a Saab, despite featuring a few pieces from the GM parts-bin.

Petrol power will likely be provided by three turbocharged engines including a 1.6-liter four-cylinder with 160hp, a 2.0-liter four-cylinder with 210hp, and a 2.8-liter V6 with 300hp. On the diesel side, we can expect two turbocharged units which will produce 160hp and 190hp. Future variants may include a petrol-electric hybrid and a biofuel model.

As we have previously reported, the 2010 9-5 rides on a "sportier" version of GM's Epsilon II platform which also underpins the Opel Insignia and Buick LaCrosse. The new platform allows for additional interior room and optional all-wheel drive.

Expect the new 9-5 to hit European showrooms in April 2010, with a base price around €35,000.
