Fernando Alonso's sweat and effort to push his car back to the pits in Q2 came to naught due to what he called a "strange" rule.
The double World Champion made it into Q2 at the Hungaroring and had hoped to secure a solid qualifying position.
However, that hopes were dashed when his MP4-30 suffered an electrical problem causing him to stop out on track.
Despite the heat and humidity, Alonso pushed his car back to the pit lane, his efforts eventually getting some help from track marshals.
But, once he was back with McLaren, he was informed that his qualifying was over and not because of the car.
"I got lucky because I had some help, but when I arrived to the garage they told me I was not allowed to go back out again," he told Autosport.
"The rules say the car has to arrive by itself into the garage, so it was a lot of effort for nothing.
"It's a little bit of a strange rule because we've seen so many times a car arriving on a crane and starting again the session.
"For me, [the car problem] was the wrong time, the wrong moment.
"It was something electrical, some connector, the power went off and that was a shame.
"We've been quite competitive all weekend, more or less in the top 10 in all the [practice] sessions, so it had been a good weekend for the team."
