1. Qualifying could be crucial: The whole podium in Santiago last year came from the first two rows of qualifying. Sam Bird came from fourth on the grid to win and Pascal Wehrlein and Daniel Abt held on to their second and third spots from qualifying. The 2018 race had the three top places on the grid taking podium spots.
2. It's a circuit that can be tough on cars: Eight cars failed to make it to the end of last season's Santiago race and six ended with a DNF next to their name in 2018. In addition, Santiago's hairpin has caused plenty of awkward moments for drivers. Sebastien Buemi, who led the race from pole last season, had to to retire after hitting a wall. Throw in expected track temperatures of 45C and you have a race to be reckoned with.
3. It's a good track for Sam Bird: The Brit will fancy his chances of improving on his current third place in the championship when he returns to the Chilean capital. Bird won last year's race with a patient drive and took 11 points from the 2018 race for fifth place and the fastest lap.
4. Home advantage means little: The two previous editions in Chile have seen just two of four drivers from South America score points - and only 10 points in total. The best was Nelson Piquet Jnr's sixth-place finish in 2018, with Jose Maria Lopez managing ninth last season. Other than that, Felipe Massa had a DNF last year and so did Lopez and Lucas Di Grassi in 2018. Surely their luck must change?
