An Anniversary Edition of the otherwise carryover 9-5 sedan is the only major change in lineup for 2007. An Aero package also replaces last year's Sport package. All versions, including the base 9-5 2.3T, have a 260-horsepower turbocharged 2.3-liter four as standard equipment. A five-speed manual gearbox is standard, with a five-speed automatic available as an option. Other stock gear includes a sunroof, leather seats, and 17-inch alloy wheels; a six-CD, in-dash changer also comes standard in the 9-5, along with XM satellite radio and an input jack for MP3 players. All models feature a cooled glovebox to keep drinks chilled as well as leather-trimmed interiors with dual-zone climate control and can be ordered with the latest version of GM's OnStar concierge system with voice recognition.
