What is the trackpad on a P17 G2?

Thinking about buying one, yet still trying to decide mainly because Im worried the trackpad may not be very good?

Im writing this on a T480, the trackpad I will say is barely acceptable. Does the P17 use the same one, or is it any better? Same size?

The reason for going with the P17 is simply I need a bigger screen, 16 does not really do it for me. That leaves out the P16s and the P1s...

Also, would it be possible to upgrade it to something better?

It seems Lenovo is really trying to improve their trackpad game with the newest Sensel ones, lets hope they put out a 17 inch model with one soon.
