Minimal on-track programme for McLaren due to rain

By on

Persistent wet weather hampered running for the majority of teams at Portimao. With much to be risked by running in the slippery conditions, the test team conducted a minimal on-track programme today, using a 2008-spec rear wing as a precautionary measure to increase downforce during the runs. Despite the weather, the team carried out a number of systems checks on the MP4-24 and will continue the programme tomorrow.
