If wondering...
 
FWD = Front Wheel Drive (only its front wheels can spin)
AWD = All Wheel Drive (all 4 wheels can spin).
 
TCS (sometimes called TC) = Traction Control or Traction Control System means that if its special "wheel sensors" computer senses 1 wheel is spinning `too much`, it automatically applies brakes to that specific "spinning" wheel. Thus, forcing its opposite drive wheel to spin - instead of allowing its single spinning wheel to continue to spin. TCS exists on either FWD (Front Wheel Drive) or RWD (Rear Wheel Drive) vehicles. When TCS exists on all 4 wheels, its called Stability Track system. And yes, TCS on the front wheels and Stability Track across entire vehicle exists on the newer technology vehicles - like my wife's new 2009 mini-van.
 
If wondering, my wife has an older technology 2003 FWD RDV (her "in town" run-about vehicle) that only has TSC on its Front Wheels. When one front wheel spins too much, that single wheel speed is forced to slowed down, thus forcing the other wheel to take more traction. From a white board perspective, vision TCS as Traction Balance System - because it balances 'drive power' delivery to the other wheel(s) - that have better traction then its single spinning wheel.
 
Being a lighter weight 2003 FWD RDV (compared to more steel parts in its heavier weight AWD version), my wife's vehicle also gets good MPGs. Not as good as some better wind dynamic 3.4L vehicles (like a mini-van with 3.4L engine) but it gets much better MPGs then an AWD RDV (with 3.4L engine).

Hope this helps...
