Lewis Hamilton and Kevin Magnussen will start from the pits after both encountered trouble during qualifying for the Hungarian Grand Prix.
Mercedes confirmed Hamilton will have to race with a new chassis, engine and gearbox following an engine fire as a result of a fuel leak.
Magnussen meanwhile will also require a new chassis due to a Q3 crash which damaged the carbon-fibre tub beyond repair.
The Danish driver was caught out by the sudden shower, sliding off track at turn one and into the tyre barrier.
“It was completely dry at the last corner until the straight, so I braked a little bit early – like 20 metres – and it was just wet. I locked up and didn’t stop really. Unfortunate,” he said.
He had qualified 9th in his McLaren whilst Hamilton qualified 21st.
