McLaren Formula 1 racing director Eric Boullier has downplayed the recurring issues that caused the team to suffer three on-track stoppages during th🐷e ope🔯ning day of the second pre-season test in Barcelona on Tuesday, saying the team is "not overly concerned".

Stoffel Vandoorne suffered two electrical issues in the morning session before a hydraulic leak sidelined him for a third time ꦯlater in the day, forcing McLaren to end its programme two hours early🎃.

Vandoorne managed a total of 38 laps through the day, putting McLaren just 10 laps ahead of its total at this point last year in pre-🍷season testing, but Boullier is not concerned.

"Today wasn’t the day we had hoped for on track, ♕but, despite this, we aren’t overly concerned about th🅷e issues that we’ve faced today," Boullier said.

“It’s obviously not the productive day we had planned, but the problems – a ba✨ttery issue and a hydraulic leak – are the types of niggles that we almost hope and expect tဣo face during testing, in order to prepare us properly for the season ahead.

“We are here to test, and today is what sometimes happens in testing. I🍨t’s not ideal, and we would have liked more track time,🏅 but we’re working on it, we’re learning from it, and we’ll return to the track tomorrow armed with more information."

Renault chief technical officer Bob Bell confirmed the French manufacturer🌞 was responsible for the battery issues that hit McLaren and fellow engine customer Red Bull.

"Those problems could have ෴affected any of the three teams, so of course it's an issue for us," Bell said.

"But the reason we do this testing of those componenᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚts before going to Melbourne is to find the ones that have got problems, so that w✅hen we go to Melbourne we have a stock of batteries that we are completely confident in.

"It's the right thing to do, we have found some that are🌼 not fit for purpose and that's great."

"Today was challenging because of the issues we had which interrupted our running for today. We had a few stoppages on track, and we’ve been working through each one to make sure we’re fully prepared for tomorrow," Vandoorne said after losing the bulk of his t🐽rack time on Tuesday.

“The kinds of issue we’ve had werenꦚ’t particularly serious, but have taken a relatively long time to fix, so we weren’t able to run as much as we planned. The conditions this afternoon were quite tricky due to the wind, so the 🌞running we did wasn’t so representative.

“We’re hopeful the issues have been fixed and we ca🗹n have a more productive day tomorrow."

Fernando Alonso will tak𓂃e over for Wednesday's runnin🦩g in Barcelona, due to start at 9 a.m. local time.
