No changes were made to the Cadillac STS-V for model year 2009.
The 2009 Cadillac STS-V is based on its STS counterpart. To distinguish itself as the sport sedan in the STS family, the STS-V sports a polished stainless steel wire mesh grille and a mesh-covered intake vent below the front bumper. Additional chrome molding, a lip spoiler, and 10-spoke alloy wheels with 18-inches in the front, 19-inches in the rear, hint at the combination of performance and luxury that the STS-V provides. The raised hood makes room for the supercharger.
Standard exterior features include variable intermittent rain-sensing wipers, rear defogger, power heated mirrors, power sunroof, remote anti-theft alarm system with engine immobilizer, daytime running lights, fog lights, high pressure headlight washers, and auto delay off dusk-sensing Xenon HID (High-Intensity Discharge) headlights.
The interior of the 2009 Cadillac STS-V offers hand-wrapped leather upholstery and olive ash burled wood and tasteful aluminum interior trim throughout the cabin. The cabin is elegant and refined; seats are leather-covered and offer suede fabric inserts. They’re well-bolstered and comfortable, even on long trips. The back seat is roomy, and the Bose audio system’s surround sound fills the cabin, thanks to its fifteen speakers.
Standard interior features include power door locks, power windows, eight-way power heated driver and passenger seats with power lumbar support and height adjustment, leather/suede upholstery, bucket front seats, rear ventilation ducts, cruise control, front console with storage, speed-proportional power steering, universal remote transmitter, 12-volt power outlet, rear parking sensors, leather-wrapped tilt/telescoping steering wheel with audio and cruise control functions, interior ail filtration, dual-zone climate control, leather/wood interior trim, heated steering wheel, auto-dimming rearview mirror, memory settings for two drivers, keyless ignition/entry, tachometer, trip computer, external temperature display, head-up display, DVD-based navigation system with eight-inch LCD touchscreen and voice activation commands/real-time traffic reporting, pre-wired for cell phone, Bluetooth connectivity, OnStar telecommunications service, and AM/FM/six-CD/Satellite premium Bose audio system with 15 speakers, subwoofer, surround sound, and radio data system.
The trunk offers 13.8 cubic feet of cargo space, which is smaller than other vehicles in its class.
Performance & Handling
The STS-V’s 4.4-liter, supercharged V-8 engine generates 469 hp and 439 ft-lb of torque. It has been clocked at 5.1 seconds in a zero-to-60-mph sprint.
The engine sits lower in the STS-V than in the STS. This placement creates a lower center of gravity for the STS-V, which helps stabilize the vehicle when cornering. StabiliTrack stability control and all-speed traction control are responsible for the STS-V’s impressive handling ability. High-performance Brembo disc brakes and ABS provide adequate stopping power when you’re putting the STS-V through its paces.
The six-speed automatic transmission with Driver Shift Control (DSC) offers clutchless manual shifting. ZF Servotronic power-assisted rack and pinion steering and sport-tuned suspension are also standard.
Active steering helps to improve maneuverability. A small actuator between the steering wheel and the front wheels works in conjunction with the electronic stability control system and adds up to 12 degrees of steering input in adverse conditions.
DSC lets the driver quickly switch from automatic to the clutchless six-speed high-performance manual transmission. When the driver moves the gearshift lever into DSC mode, a quick tap on the lever results in smooth upshifts or downshifts. The Transmission Control Module (TCM) monitors vehicle speed and torque to determine if shifting is appropriate. It also has coast clutches to provide engine braking in any gear.
Drivers and passengers who are used to riding in a regular luxury sedan may find the ride quality a bit rough due to the sport-tuned suspension.
2009 Cadillac STS-V’s standard safety equipment includes rear limited slip differential, four-wheel 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, front and rear ventilated disc brakes, electronic brake force distribution, stability control, traction control, tire pressure monitoring, blind-spot alert system, rearview camera, and lane departure warning system, and a full complement of airbags. OnStar service can alert authorities if assistance is needed due to an accident.
In government crash testing, the 2009 STS-V received four out of five possible stars in frontal impact tests and five stars for side-impact tests.
