2011 The The Saab 9-5

2.0T models have a turbocharged 2.0-liter inline four. Known as the LK9, this 16-valve, DOHC engine is part of GM's Ecotec family. It is all aluminum, with cast-iron cylinder liners and twin balance shafts for greater smoothness. With a compression ratio of 9.5:1 and up to 12.3 pounds of boost from its intercooled turbocharger, the LK9 produces 210 horsepower and 221 lb-ft of torque.

The Saab 9-5 design is over a decade old, but there are many changes on the horizon, especially for the power plant of the 2010 Saab 9-5. Under the new ownership of GM, Saab will be offering multiple engine options for the newest Saab 9-5. All of these new engines have been redesigned under the supervision of GM.
