The Haas F1 Team will not take part in Formula 1's second in-season test scheduled right after next week's Hungarian Grand Prix.
The two-day test will take place at the Hungaroring on July 31 and August 1 and will feature all teams, with the exception of Haas, and several F1 development drivers.
Haas team boss Guenther Steiner invoked F1's recent concentrated calendar of events which included five races over six weeks as the reason for which the US outfit will begin its summer break earlier than its rivals.
"Instead of participating in the test in Hungary, Haas is using the time to analyse the data it received from its recent Pirelli tyre test at Silverstone, from past Grands Prix and from our simulator work," said Steiner.
"Between the data our drivers have been able to gather that is directly applicable to their driving styles in our cars, and this current run of five races in six weeks, we determined our time was best spent at the factory."
If Haas had decided to stay on at the Hungaroring it would have run F2 racer and Haas development driver Santino Ferrucci.
The young American was banned recently by the FIA for two races for his antics at Silverstone two weeks ago and subsequently fired from his F2 team Trident.
Haas has yet to decide whether Ferrucci will remain with the US squad.
"Haas F1 Team remains committed to gathering all of the facts and having in-person conversations with all the individuals involved in the situation," Steiner said in a statement to Sky Sports F1.
"We are being diligent, but our priority is the last two races before the summer shutdown."
