An issue with the engine in his Williams FW33 meant that Rubens Barrichello completed only 52 laps on the first day of pre-season testing in Barcelona.
A damp track in the morning meant a late start for the team, and track time was further limited as the Cosworth engine was changed midway through the day.
“We didn’t have enough set-up time today,” explained technical director Sam Michael. “The track was moist to start and didn’t start ramping up until late morning, at which point we encountered an issue with the engine. Over the break, we changed the engine and did just one proper run at the end of the session. All of our running was carried out on the medium compound tyre.
“Despite the downtime, we actually tested and measured quite a few aero and systems items in the background. Tonight, we will re-activate KERS in preparation for tomorrow's running.”
Barrichello was pleased to get a chance to try out the new Pirelli intermediate tyre but was ultimately disappointed not to get more laps under his belt.
“We did some laps in the wet this morning which was good as it allowed us to get a feel for the car on intermediate tyres,” said the Brazilian. “Unfortunately, we didn't get much running in the dry. I had a short run after lunch, but we had to make a precautionary engine change so my day was cut short.”
Barrichello will be back in the car on Saturday.
