So it starts snowing yesterday night in Maryland yesterday so I decided to just take the Explorer out to whip it around in the snow because the roads were extra slipper with about a half inch of snow. I have the 4WD so I wanted to test out all the terrain management settings. Normal Mode: Very spot on, even though I didn't have it in snow mode, I would turn and I didn't even feel the car slipping at all and the traction control fired perfectly. No understeer or oversteer and easily kept the vehicle where I wanted to go. I did this multiple times whipping the car faster and faster as I go moderating the accelerator. Snow mode: Controls my accelerating so nicely and no slippage whatsoever. I tried punching the gas but the car controlled the throttle perfectly. Kept my inputs well controlled and really prevents any lead foots from screwing you over. Much improvement from traditional 4WD systems in my opinion. Sand Mode: For the heck of it, I wanted to see how sand mode would perform since it provides killer torque and power. You can really notice the difference from having traction control to no traction control. You'd be in so much trouble with the car whipping around. I understeered like crazy and the car wouldn't stop. It kept going straight wherever I turned. I would only put sandmode in if I was driving over like 10 - 12 inches of snow like I did last year to get out of a situation where I got stuck. The vehicle electronics are dead on accurate in this car,much better than the traction control on my friend's 2007 Cadillac CTS which you would feel the body slipping for about 1 - 2 seconds before it responds. Also much better in keeping the vehicle in control than the traditional 4WD. I did this on pavement that hasn't been plowed or salted yet.
