About the 2009 Cadillac DTS
Single DTS generation (2006-2011), fourth model year, late-cycle pre-refresh/pre-discontinuation period.
Cadillac positioned the DTS as its traditional full-size luxury sedan: a roomy, quiet, front-wheel-drive car built around comfort, V8 power, and an easygoing highway ride. The core appeal was straightforward American luxury rather than sport-sedan sharpness. Compared with rivals, the DTS leaned on generous passenger space, a large trunk, soft ride quality, and familiar controls instead of chasing newer high-tech or performance-focused formulas.
The 2009 DTS is a traditional full-size luxury sedan focused on quiet highway comfort, generous passenger room, and V8 power rather than sporty handling. The Base trim has leather seating, xenon headlights, dual-zone automatic climate control, remote start, and 17-inch aluminum wheels.
