F1 journalist Dan Knutson in Barcelona: "Jolyon Palmer did only 37 laps on Monday because of software problems on the Renault.

“Disappointing first day I would say,” he said yesterday. “It’s been challenging. Usual first day issues. We would definitely have liked to get some more laps under our belt but we understood some issues, got some laps in at the end. We just need to work hard tonight and get a lot more in tomorrow.”

"Unfortunately he only completed 42 laps today before a power unit problem brought things to a halt.

"Meanwhile, Sebastian Vettel, Daniel Ricciardo, Nico Rosberg, Marcus Ericsson, Valtteri Bottas, Fernando Alonso and Max Verstappen have all done more than 100 laps today."
