Listen to the publicity blurbs, and you would think that the 9-5 is a brand-new vehicle. Uh, no. This is a pure refresh, incorporating 9X concept car styling, a modestly updated interior, and a range of upgraded engines that include more power for the top-line Aero, now making 256 hp, and a BioPower engine that can run on any mixture of ethanol and gasoline. Saab says that the 9-5 Sedan and SportCombi (wagon to us) have vastly improved chassis dynamics, but that would take a miracle given how long in the tooth the 9-5 truly is.
