Haas boss Guenther Steiner says everyone in Formula One's tight midfield should be considered a threat in the second half of the season due to the unpredictable nature of the fight so far.
Williams, Toro Rosso, Haas and Renault -- occupying fifth to eighth position -- are split by 15 points in the championship, with McLaren a further 15 behind after a strong result at the Hungarian Grand Prix. McLaren is expecting to make steps forward after the summer break with Honda, while Renault's latest upgrades showed a clear improvement at Silverstone and Budapest.
Haas' results have been inconsistent, with two scoreless races following strong outings in Azerbaijan and Austria.
