The remodelled Zandvoort circuit is due to reopen on Friday next week following the completion of construction work at the track.
The specifications of the revised Zandvoort circuit will not be withheld from teams in an effort to create more unpredictability when F1 returns to the track this year.
Formula 1 drivers say Zandvoort is going to be a “massively quick” circuit for their cars next year, but are concerned overtaking will prove difficult.
Zandvoort circuit director Jan Lammers says some corners will be eased to aid overtaking at the 2020 Dutch Grand Prix but they won’t change “our Eau Rouge”.
The Dutch Grand Prix will return to Formula 1 next year at Zandvoort, 35 years since the race was last held at the seaside circuit.
