The 2005 Cadillac DeVille carries over from the previous year with no major changes. Cadillac’s Night Vision feature is available on models built early in the model year. The standard OnStar communication system gets hands-free technology.
The 2005 Cadillac DeVille has a more rounded, bulkier appearance than previous-generation models of the 1990s and before. Built on a 115.3-inch wheelbase, it measures 207 inches long overall. StabiliTrak electronic stability control is standard on the DTS trim and optional on the base and DHS models.
The 2005 Cadillac DeVille Base rides on 16-inch alloy wheels and includes intermittent wipers, a rear defogger, dusk-sensing auto-delay-off headlamps, and turn signal mirrors. The DHS upgrades the tires to chrome alloy, although it remains the same size. Rain-sensing wipers, a power rear sunshade, and power heated mirrors with reverse tilt are also standard on the DHS. The sportier DTS includes all of those features and rides on 17-inch wheels.
A 40-20-40-split front bench seat is standard on the 2005 Cadillac DeVille base and DHS model. The DTS comes with front bucket seats and a floor-mounted shift lever. Even with the front seats moved all the way back, rear legroom is ample. A trunk with 19.1 cubic feet of storage space has a low lift-over height for easy loading. The DHS and DTS sedans come standard with heated and cooled front seats and a heated steering wheel. These are available as an option on the base model. XM Satellite Radio and a navigation system are optional on all models. The base model comes equipped with 10-way power driver’s and passenger seats, leather upholstery, speed-proportional power steering, a tilt-adjustable steering wheel with built-in audio and cruise controls, three-zone climate control with air filtration, and an eight-speaker AM/FM in-dash CD player stereo system. The DHS adds multi-level heated driver’s and passenger seats with power lumbar support, wood trim on the center console, doors and dash, a wood and leather steering wheel, memorized audio and climate control setting for two drivers, and an upgraded Bose premium audio system with speed-sensitive volume control. The DTS includes front bucket seats and a heated leather steering wheel. Most features of the higher trims are available on the base model as part of a special Limited options package. A Premium Luxury Package is available for the DTS and includes rear side airbags, a power tilt/telescoping steering wheel, a wood shift knob, and a rear obstacle detection system.
Performance & Handling
Two versions of Cadillac’s 4.6-liter, Northstar V-8 engine are available on the 2005 DeVille. The engine in the base and DHS models is capable of 275 horsepower and 300 lb-ft of torque. The high-output, 300-horsepower version in the DTS model produces 285 lb-ft of torque. Both engine versions are mated to a four-speed automatic transmission that directs power to the front wheels. The engine performance is smooth and refined, and the cabin is well insulated to keep road and wind noise to a minimum.
Standard safety equipment for the 2005 Cadillac DeVille includes traction control, four-wheel anti-lock disc brakes, load-leveling rear suspension, and front side-impact airbags. Rear side airbags are optional. Standard equipment includes child seat anchors, a remote anti-theft system, rear door child safety locks, cornering lights, and a post-collision safety system. The DTS model comes with an antiskid system that’s available as an option for other models. It receives four out of five stars across the board from the National Highway Traffic Safety Administration (NHTSA). The NHTSA also gives it a five-star rollover rating.
