Do our cars have TCS and VDC? If they do also have TCS, how do I turn it off?

 

just VDC. Vehicle Dynamic Control, which encompasses the traction control.

 

dude read your manual,

 

To the left of the sterring wheel and around the knee area are a cluster of buttons. The furthest to the left marked VDC; push it and a "VDC OFF" light will pop up on you gauage cluster.

This does not turn the VDC off, rather it reduces its intervention to almost non-existent (so I've read in reviews).

Push the button again to turn off the warning light and turn VDC back on.

 

There's a button right next to your trunk release on your left side that says VDC off, and a light should go on in your dash saying that the VDC is off.

 

Both according to http://www.infiniti.com/g_coupe/spec...ons/index.html

Vehicle Dynamic Control (VDC)
A change in traction can affect your car's stability during cornering. VDC[1] uses an array of sensors to help determine your steered path and to help keep you in control. If your vehicle begins to understeer (plow forward) or oversteer (fishtail), VDC applies appropriate brake pressure to individual wheels and/or reduces engine output to help keep both ends in line.

Traction Control System (TCS)
G37 Coupe's integrated Traction Control System (TCS) senses wheelspin while accelerating and automatically reduces engine output and/or brakes the spinning wheel to help regain traction.

 

like people said, both and you can only lower the vdc sensitivity. pulling your fuse is the closest to disabling traction control.
