Red Bull has been embroiled in a technical controversy about its engines, which stewards said last week could give the team additional aerodynamic grip and help reduce wheel spin.
In Hungary, the team will have to revert to a torque setting used earlier in the season. But Sebastian Vettel downplayed its importance to Red Bull's performance.
"It's not as if the car doesn't work anymore," Vettel said. "I'm quite confident that nothing will change."
Vettel is also confident Red Bull will be able to catch Alonso.
"We still have a lot of races to go," Vettel said. "The season has been unpredictable so far and there's no sign it should be different in the next couple of races."
Red Bull holds a commanding lead in the constructors' championship despite Vettel being demoted from second place to fifth in the German Grand Prix at Hockenheim last week after being penalized 20 seconds for an illegal passing manoeuvre.
