|An interrupted session for McLaren at the second day of pre-season testing as Stoffel Vandoorne got behind the wheel of the MCL33 for the first time. Conditions all day have been much colder than expected, with track temperatures well below the ideal operating window for both the car and tyres.
Given the weather, the team opted to run a number of installation laps in the morning in order to gather important correlation data and perform systems checks – necessary test items that can still be completed in adverse conditions.
Around lunchtime, the team detected high temperatures under the bodywork, caused by a broken exhaust clip leading to hot air being blown back into the car and onto the wiring loom, which includes the brake line. The team opted to strip down the car to perform further investigations as a precaution.
Once happy with the investigation and subsequent repair, the car was again readied to return to the track, but the team opted not to run just before the flag dropped due to the worsening weather conditions.
Stoffel completed 37 laps and clocked the third-quickest time of the day.
