With key fob in pocket, our STS knew of our presence, unlocking its doors in anticipation of the coming drive; the same fob permitted us to start the car with...
a push of a button. On the road, we found the STS' 3.6-liter V6 to be quiet and free of vibration, though at full throttle the sound emitted from the engine bay was somewhat coarse.
Power, on the other hand, was readily available and fuel economy proved surprisingly good, especially on long highway trips. The STS' rear-wheel-drive platform and sport-tuned suspension allowed little body roll and gave predictable handling. The STS tracked brilliantly in tight turns, though the steering response was somewhat soft and slow to react. StabiliTrak stability control proved admirable in keeping the STS from skidding off course.
