Well, watch for yourself as Lewis Hamilton's Australian GP pole position laps from this year and last are given the SkyPad treatment after the new season's opening qualifying session.

After claiming pole in 2016 with a lap of 1:23.837, Hamilton went 1.7 seconds faster in the new Mercedes W08 - so watch above as Paul Di Resta analyses where the 2017 car made the difference.
