Hmm. Two different systems.
TRACS
This system uses the ABS to slow down a drive wheel that has lost traction and has begun to slip. Does not affect fuel economy and has nothing to do with the transmission. TRACS can be a nuisance at times (and a help at others). System operates at speeds below 25. I turn it off during 'city' driving on rough pavement because it frequently activates which can be irritating.
SPORT (S) vs ECONOMY (E)
The Sport (S) setting holds gears longer during acceleration, and activates kickdown faster when you're already in a running gear and suddenly demand more power.The Economy (E) setting makes the car a little more sedate, or in my mind, lethargic. I get the exact same fuel economy using either setting, so I leave it in S.
WINTER (W) AND TRACS WORK WELL TOGETHER
During my daily winter commute, I have to climb a steep, winding hill that's usually icy. I have to do this after a stop sign, turning 90-degrees left, the road banking to the outside of the curve. With the car in Winter (W) mode and with TRACS on, this tough little spot is a piece of cake. Most of my neighbors drive the long way around to avoid this spot, entering the neighborhood from a more remote and inconvenient entrance.
