Have they released what layout of the Portimao circuit they will use yet? I personally hope they use the Bahrain Turn 1/2 style layout, with the tighter hairpin at Torre Vip to aid overtaking opportunities.
I reckon they can get away with using the fast first corner because the cars will be comfortably flat-out through the final corner to the point where they can follow each other easily. Plus that chicane looks horrid, like the fiddly chicane at Fuji.
