2006 Cadillac STS-V

The 2006 Cadillac STS-V is General Motors most intense expression of Cadillac power and performance. Designed for everyday driving, the STS V has been developed to deliver supercharged, rear-drive performance with an elegant design statement that is unmistakably Cadillac.

At the heart of the STS V is a new, 4.4-liter version of the Northstar engine outfitted with a positive displacement intercooled supercharger. The dual overhead cam (DOHC) V-8 engine delivers the highest horsepower rating of any production Cadillac engine to date. Called the Northstar V-8 SC (supercharged), the engine produces 440 horsepower (328 kW) at 6400 rpm. The Northstar V-8 SC generates 120 horsepower (90kW) and 115 lb.-ft. (156 Nm) of torque more than its naturally aspirated counterpart, while its specific output of 100 horsepower per liter makes it one of the world's highest specific output production V-8 engines. The DOHC engine includes variable valve timing that enables outstanding top-end performance while maintaining the expected refinement and quality associated with a luxury marque.

The aggressive torque curve enabled by the choice of a supercharged engine gives the STS-V acceleration capable of placing it firmly in the under-5-second-club for 0-to-60 time. The refined shift feel is enabled by careful electronic calibration of both the engine and transmission. During shifts, power is instantaneously lowered, then ramped back up carefully to make gear changes virtually unnoticeable. The all-new Hydra-Matic 6L80 – the only transmission offered on the STS-V – is one of the most technologically advanced automatic transmissions in the industry, using clutch-to-clutch operation and an advanced integrated 32-bit transmission controller to deliver smooth and precise shifts.

The vehicle has track-capable acceleration, braking and cornering abilities. This is due, in part, to increased tire sizes, increased brake rotor diameters, larger pad areas, and larger calipers; increased stiffness stabilizer bars and suspension springs; a faster steering ratio and chassis tuning aimed at delivering high performance without punishing the driver.

Exterior elements on the STS-V enable higher-performance capabilities; yet express the sophisticated elegance associated with the STS name. The interior of the STS-V reflects craftsmanship with the addition of more leather-wrapped surfaces to promote a high-quality, tactile feel and distinctive, crafted appearance.

GM is the only automotive manufacturer committed to offering a full range of vehicles with safety protection before, during and after a collision. All OnStar-equipped vehicles come with Automatic Crash Notification. Additionally, the 2006 STS-V will offer the GM-exclusive Advanced Automatic Crash Notification system.

The STS-V was engineered and executed by GM's Performance Division, an in-house center designed to explore potential enthusiast-oriented versions of production models. No engineering, design or assembly functions were outsourced – the vehicle is truly an original equipment offering.
