Lewis Hamilton set the quickest time of a heavily disrupted first practice at Zandvoort.
Red Bull’s Max Verstappen was second, 0.097 seconds behind his championship rival.
Aston Martin’s Sebastian Vettel experienced an issue with his power unit, which forced the German to stop on track and triggered a lengthy red flag period.
The session experienced a 33-minute delay due to the engine failure as the marshalls tried to clear away the Aston Martin, but were cautious due to concerns about the voltage of the car.
Thousands of Dutch fans poured into the circuit to witness Formula 1’s first visit to The Netherlands for 36 years but weren’t able to see much action due to the lengthy stoppage.
Before the red flag, most drivers opted for the hard tyres, but with limited time remaining after the delay, all went out on softs.
Ferrari was an impressive third and fourth, with Carlos Sainz heading Charles Leclerc.
Hamilton’s Mercedes teammate Valtteri Bottas was fifth, ahead of the Alpine’s of Fernando Alonso and Esteban Ocon.
Alfa Romeo’s Antonio Giovinazzi was eighth, with the other Aston Martin of Lance Stroll in ninth.
Pierre Gasly completed the top 10 in his Alpha Tauri.
Lengthy delay hurts teams
It’s been 36 years since F1 last visited the Zandvoort circuit, and since then, the track has had a major facelift.
Two heavily banked corners have been added and many other turns have been reprofiled.
Most drivers have raced at the circuit in junior categories, except for Yuki Tsunoda who has never raced at Zandvoort before and was eager to learn the track quickly, but became the first spinner of practice in the Alpha Tauri.
With much of the grid being unfamiliar with the narrow and twisty Dutch track, a lengthy stoppage will have done them no good.
F1 practice sessions were shortened this season to just one hour, rather than the previous 90 minutes the teams received for first and second practice last year.
