A complete redesign for 2006, the STS is a rear-wheel-drive full-size luxury four-door sedan with five-passenger seating capacity. The base engine is the 3.6Liter 24 valve with variable-valve-timing that produces 254HP, or the optional 4.6Liter Northstar V8 that generates 320HP. The STS is also available with all-wheel-drive configuration. The 6L50 six-speed automatic transmission with driver-shift offers clutch less shifting using a 32-bit transmission controller.
