Saab's 9-5 is alternately characterized as the savior of the brand or its final death knell; excitingly retro-modern or achingly bland. Whether you love it or hate, however, you can know learn all about it. The full spec sheet for the U.S. 2011 Saab 9-5 is out (and yes, it's billed as a 2011 model), courtesy of General Motors.

The information was dug up by the community at GM Inside News, with a direct link to the full specification sheet, including standard features, options and packages. While it's a bit too detailed to cover in full, suffice it to say that the base spec explains the expected slighty-sub-$50,000 starting price.

Four different models will be available, including the Turbo4, Turbo4 Premium, Turbo6, and Aero XWD. The prime powertrain specs: the 2.0-liter turbocharged four-banger gets 220 horsepower and 258 pound-feet of torque, while the turbo 2.8-liter V-6 gets 300 horsepower and 295 pound-feet of torque. Those figures put the V-6 on even ground with BMW's 35i models and Mercedes' new V-6s, while offering a (presumably) more efficient four-cylinder option otherwise not found in the full-size luxury sedan segment in the U.S.

In terms of suspension, the 9-5 gets the HiPer Strut treatment in the six-cylinder models (Turbo6 and Aero XWD), while the four-cylinders get a standard MacPherson strut system. A special "F45" package upgrades the Aero XWD to a continuously-variable, real-time damping suspension with comfort, sport and "intelligent" settings.

All models come standard with a full complement of airbags, a nine-speaker audio system, and other goodies like climate control and ambient lighting. The base Turbo4 gets 17-inch alloy wheels standard, while the Turbo4 Premium and Turbo6 get 18x8" wheels with a 14-spoke "turbine" design. The Aero XWD gets 18x8" wheels, too, but in a five-double-spoke configuration.

In addition to the spec sheet, the GM Inside News thread indicates some buyers are being told the new 9-5 will be on dealer lots within two to three weeks. Start putting together those financing packages and getting ready to trade in if you want one, as volumes are likely to be limited at first.
