Launch Control (Track
Mode Only)
A Launch Control feature is
available, within Competitive Driving
Mode (except Z51 with Magnetic
Selective Ride Control) or
Performance Traction Management
(Z51 with Magnetic Selective Ride
Control), on all vehicles to allow the
driver to achieve high levels of
vehicle acceleration in a straight
line. Launch Control is a form of
traction control that manages tire
spin while launching the vehicle.
This feature is intended for use
during closed course race events
where consistent zero to
60 and quarter mile times are
desirable.
Launch Control is only available
when the following criteria are met:
. Competitive Driving Mode is
selected (except Z51 with
Magnetic Selective Ride Control)
or any of the Performance
Traction Management modes
are selected (Z51 with Magnetic
Selective Ride Control). The
TCS light comes on the
instrument panel and the
appropriate DIC message
displays.

I believe that it is standard on all C7's but not entirely sure of that.

EDIT:. just checked and it appears all C7's have launch control, both auto and manual, both base and Z51.
