Exterior

The 2009 Cadillac STS was redesigned in 2008 and its exterior design remains unchanged for 2009. The front end is dominated by Cadillac’s signature wire mesh and chrome grille and the wire mesh air intake below the front bumper. It also features Cadillac's vertically-arranged headlights. A small spoiler is situated on the rear deck lid; the vertically placed taillights follow the stacked look.

2009 Cadillac STS standard exterior features include variable intermittent wipers, a rear defogger, power heated mirrors, a remote anti-theft alarm system with engine immobilizer, daytime running lights, fog lights, and auto delay off dusk-sensing headlights.

Additional options include dusk-sensing Xenon HID (High-Intensity Discharge) headlights, high pressure headlight washers, head-up display, GM's Magnetic Ride Control (MRC) adaptive suspension system, and 18-inch wheels.

The Performance Handling package adds upgrades to the wheels, tires, and brakes.

Interior

The interior of the 2009 Cadillac STS is luxurious and elegant. This year, wood trim is optional; it complements the alloy trim throughout the cabin. The STS is replete with high-tech gadgets; controls are within reach, and gauges are easy to read. Adaptive cruise control and keyless ignition features are available. Head-up display lets drivers keep their eyes on the road without missing out on vital vehicle stats and information.

2009 Cadillac STS standard interior features include power door locks, power windows, tire pressure monitoring, eight-way power driver and passenger seats with height adjustment, bucket front seats, rear ventilation ducts, folding center armrest with pass-through, keyless ignition/entry, cruise control, speed-proportional power steering, 12-volt power outlet, rear parking sensors, leather-wrapped tilt/telescoping steering wheel with audio and cruise control functions, interior air filtration, dual-zone climate controls, wood/alloy interior trim, auto-dimming rearview mirror, tachometer, trip computer, external temperature display, compass, pre-wired for cell phone use, OnStar telecommunications service, Bluetooth connectivity, and AM/FM/CD/Satellite Bose premium audio system with eight speakers and radio data system. The seats are upholstered in leather, and are well-bolstered and comfortable. Back seat leg room is adequate, even on long rides. The premium Bose audio system can fill the cabin with music.

Additional options include a sunroof, adaptive cruise control, lane-departure alert system, blind-spot alert system, and heated and ventilated front seats, a navigation system, and a Bose audio system with surround sound.

2009 Cadillac STS V-8 standard equipment includes eight-way power heated driver and passenger seats with power lumbar support and height adjustment, heated rear seats, heated steering wheel, memory settings for two drivers, and a six-CD changer with the Bose premium audio system.

The memory settings are challenging to set, as it's now controlled via the navigation system’s LCD touchscreen. The STS offers 13.8 cubic feet of cargo space in the trunk. The rear seats do not fold down, but the center armrest has a pass-through for longer cargo items.

Performance & Handling

The V6's 3.6-liter, 302 hp, V-6 engine is spunky and may be more than enough power for some drivers. The V6 was clocked at 6.5 seconds in zero-to-60-mph sprints. A Performance Handling package includes Brembo brakes with four-piston calipers is available for the V6 with RWD.

The V8's 4.6-liter, 320 hp, V-8 engine has been clocked at 6.3 in zero-to-60-mph sprints.

Both engines are fast, and the buyer will have to consider whether it’s worth the additional money to get the V-8 engine.

Handling is especially impressive with the optional Magnetic Ride Control suspension. The driver can select from Touring or Sport modes to determine the smoothness of the ride quality.

In Performance mode, handling is sharper but road bumps are felt more.

Braking is strong, taking 120 feet to stop from 60 mph.

Safety

2009 Cadillac STS’s standard safety equipment includes independent short and long arm front and multi-link rear suspensions, front and rear stabilizer bars, a four-wheel anti-lock braking system (ABS), emergency braking assist, electronic brake force distribution, stability control, traction control, front and rear head airbags, dual front side-mounted airbags, and full curtain airbags. A lane-departure and blind-spot alert systems are optional.

In government crash testing, the 2009 Cadillac STS received four stars out of five possible stars in frontal-impact tests and five stars for rear impacts.
