The Saab 9-5 engines and trim levels are unchanged for 2005. Arcs get a restyled wheels, and a DVD-based navigation system is now optional on all trims. The mid-size Swedish sedan is otherwise unchanged.

The same three trim levels are available in 2005, although the base Linear style is only available with the wagon. The wagon is offered in all three styles, while the sedan is available in the Arc and Aero trims. Each trim has a different power supply, but all models are powered by turbocharged 2.3 liter four cylinder engines. Horsepower increases with price.

The Linear Wagon's 2.3 generates 185 horsepower and 207 pound-feet of torque, while the Arc's mill delivers 220 horsepower and 228 pound-feet of torque. The flagship Aero includes the most potent power plant, producing 250 horses and 258 pound-feet of torque. All engines are matched with a five-speed manual transmission, while a five-speed automatic is optional.

One of the strongest selling points for both the 9-3 and 9-5 Saabs is fuel economy. EPA estimates are 21/29 mpg with the manual and 19/28 mpg with the automatic. According to owners and reviewers, the 9-5 offers an enjoyable driving experience. Despite a slight throttle response delay due to the turbo, acceleration is fairly brisk on all models. The Arc and Linear models offer a smooth ride on most reasonably groomed surfaces, but the Aero's sport-tuned suspension may be a bit too stiff for some.

The 9-5 offers class-leading cargo room in the wagon, with 73 packable cubic feet. And the sedan, which loses 16 cubic feet, compensates with one of largest trunks of any mid-size sedan.
