Fernando Alonso manages 32 laps on day three, but is forced to stop running again due to power unit issues.
McLaren and Honda enjoyed a more encouraging day in Jerez today, despite engine issues bringing proceedings to a premature halt half way through.
The car had run only six laps on Sunday and again on Monday – without recording a representative time – but this morning Fernando Alonso was able to log 32 laps before he was forced to stop. The track was damp for much of his running, so his ultimate lap times meant little.
The team noted via Twitter: “We've had a loss of cooling water pressure & have removed the power unit for inspection. That’s a long process, so it ends today's running.
“We can replace those components ahead of running tomorrow. The issue was promptly spotted by Fernando on an out lap – so quick to trace.”
Later Alonso tweeted "Big step forward," adding the hashtags #progress and #proud.
Jenson Button will take over the car once more for the final day of running on Wednesday.
