Basically "SD" mode is in between "Normal" and "Steptronic". in SD the car still is in full automatic mode but the difference lies in the way the computer holds the RPMs higher in the band to allow for better power delivery specially at lower speeds or from standstill.

When you move the gear selector to "SD" you notice immediately that the computer is holding the RPMs higher (Around 3K and up) at all times to give you better response in that region of the power band. When you switch back to normal, you'll notice that the computer will hold the RPMs at a much lower range (Between 900 and 1100 RPM on idle and 2K to 3.5K at driving speed).

So yeah when you get into the nuts and bolts of it, your CVT has 3 distinctive programs that output 3 different behaviors. This is what makes the CVT truly special.
