The V-8 engine powering the 2009 Cadillac DTS easily transports its occupants to their destination in comfort.
The base and luxury Cadillac DTS models are powered by a 275-horsepower engine that Kelley Blue Book describes as having an "utterly smooth response." The Performance model engine produces a whopping 292 horsepower. Many reviewers, including those at MyRide.com, note that given the "identical displacement" of the 2009 Cadillac, they find "negligible differences in [real world] power ratings." Car and Driver calls the power “adequate.” Edmunds reports, “Either way, the lone transmission is a four-speed automatic, which is calibrated for quicker response in the Performance model.” With the latter, “we've timed a DTS Performance to 60 mph in 7 seconds flat.” Motor Trend calls the transmission “effective, but somewhat old news in this world of five, six, and even seven-speeders.”
The EPA rates the 2009 Cadillac DTS at 15 mpg city, 23 highway for the standard version, with 15/22 ratings for the Performance model.
Most reviewers are not so pleased with the way the Cadillac DTS handles. Consumer Guide details all 2009 Cadillac DTS trims as handling "competently," though noting that the luxury sedan "is compromised by its size and heft." They add it "comfortably smothers most bumps," though it "allows some float and wander over large pavement humps." Car and Driver is also less than impressed with the handling. They chide the Cadillac DTS for a "vague steering feel."
