The 2006 STS-V epitomizes Cadillac power and performance. It carries the craftsmanship and sophistication of its STS sibling, but at an entirely different level. Designed for everyday driving, the STS-V delivers supercharged, rear-drive performance with an elegant design statement that is unmistakably Cadillac.
The 4.4L supercharged, dual overhead cam Northstar engine also powers the XLR-V, producing 469 horsepower (350 kw) at 6400 rpm and 439 lb.-ft. (595 Nm) of torque at 3800 rpm (SAE certified). Like the XLR-V, the engine delivers 90 percent of its peak torque between 2200 and 6000 rpm. Vehicle redline is 6700 rpm.
The DOHC engine has variable valve timing, enabling outstanding top-end performance while maintaining the expected refinement and quality associated with a luxury marque.
The engine's torque curve puts the STS-V in the under-5-second club for 0-to-60 time, and careful calibration of the engine and transmission enables refined shift feel. During shifts, power is instantaneously lowered, then ramped back up carefully to make gear changes virtually unnoticeable.
The Northstar V-8 SC is mated to the all-new Hydra-Matic 6L80 six-speed automatic transmission - the first use of GM's new six-speed automatic.
Exterior elements on the STS-V enable higher-performance capabilities; yet express sophisticated elegance. Exterior refinements include:Â
