ABU DHABI, United Arab Emirates (AP) Formula One stewards have cleared Ferrari and 2016 entrant Haas of any breach of rules limiting aerodynamic testing.
Stewards at the Abu Dhabi Grand Prix had been asked by Mercedes to clarify the rules due to fears that teams were skirting regulations that limit time spent in wind-tunnel testing and other aerodynamic development.
Mercedes did not directly accuse any team, but the complaint related to the close ties between Ferrari and U.S. team Haas. Ferrari, as a current competitor, was subject to testing restrictions, but Haas was not, because it enters F1 next year.
Stewards ruled Sunday that there is ''no evidence that competitors have not complied'' with the rules, but did recommend to the sport's governing body that future entrants be subject to the same restrictions as existing teams.
