Jolyon Palmer was left gutted after spinning out from 10th place at the Hungaroring.
Palmer was set to score the first points of his Formula One career but lost the rear of his car going into Turn 4 with just 21 laps remaining. He lost two positions and eventually finished 12th.
Renault had shown good pace all weekend but was caught out by the wet weather which meant both Palmer and teammate Kevin Magnussen were knocked out of Q1.
The 2014 GP2 Series champion is unsure what caused the spin.
“I’m gutted as my first points in Formula One were there for the taking,” he said.
“The car was good and I was driving well within myself in P10. I turned in the same as normal at turn four — I wasn’t hanging everything out and I was looking after the tyres — but for some reason I lost the car in a massive snap. I need to look at everything with my engineers to see if there is anything we could have done to prevent it.”
