With the McLaren more suited to the Hungaroring due to the circuit putting less emphasis on outright power, Alonso ended FP2 in eighth place, just ahead of the two Williams drivers. However, with Force India sitting the session out after a component failure in the morning, Alonso believes McLaren could drop back in qualifying.
"We have seen on Fridays that some people are not showing their potential," Alonso said. "Williams on Friday sometimes run quite heavy and slow and then on Saturday they are very competitive. Force India didn’t run today in FP2, so there are some cars that will potentially be in front of us tomorrow.
"I’m happy with the performance of the car and it’s a little bit better every race. It was a trouble-free Friday for us and both cars completed the programme without any issues. It was a positive start for us, but the important thing is tomorrow in qualifying and especially in the race."
Despite his words of caution, Alonso is still encouraged by the start McLaren has made in Budapest.
"I think it’s a combination of circuit characteristics that are just slightly better for our car. Obviously the car keeps improving and every week it’s getting better and better and it has been a good Friday. But the weekend is long and we need to see tomorrow how competitive we are and especially on Sunday where we can finish the race and hopefully score some points."
