Renault driver Jolyon Palmer says his car “just let go” as he crashed in Friday practice after losing the back at the Australian Grand Prix.

Palmer was on his best lap of the day when his car span at the final corner coming onto the pit straight.

The Renault slammed into the barriers causing a red flag as Palmer’s damaged car sat helplessly in the middle of the track.

Mechanics are now working overtime in the Renault garage to get the car ready for tomorrow morning’s final practice session.

"I just turned it in, had a bit of understeer and the car really let go on the rear,” he said.

"It caught me massively by surprise. I was on a tidy lap and attacking the last corner, didn't think too much of it, and the rear just went.

"I had no chance. It's the first time I've had that sort of problem in this car. It just let go."

Palmer completed just ten laps in FP1 and FP2 combined and could only produce a time of 1:27.549 in his short spell on the circuit.

"I was feeling good with the car, that's the sad thing really about today," Palmer said. "The few laps I did, I felt really comfortable and that we were in a good place

"That's why in FP2 I felt the confidence to go and attack straight away, and the lap I was doing was going to be pretty sensible as well.

"Losing a lot of time now puts me on the back foot. I think I can recover it, tomorrow I need to have a really good FP3."

Palmer’s teammate Nico Hulkenberg did provide a silver lining for the team as he broke into the top ten with a time of 1:25.478.
