Less happy with how the day had gone was Penske's Will Power, who had several offs in the car during the early part of the day and then had a small fire in the engine bay of the Verizon #12 car in the afternoon which he put out himself. Even so, he insisted that "I was really happy actually, the times we were putting up on really old tyres were really good."
Simona de Silvestro had a misfire problem with her car that saw the HVM car taken to the hauler while the team tried to resolve the wiring issue that was leaving the Lotus engine with only five cylinders.
"I think it was a difficult day for HVM Racing and for Lotus, but I hope we'll come back strong tomorrow," she said at the end of the session. "We have a lot of work ahead of us and we just need to go through the process. I think we see that we are a little bit behind, but if we keep improving."
But the driver with the biggest problem was Lotus Dragon Racing's Sebastien Bourdais, who was left unable to get out on track at all after his Lotus engine failed to make it to the raceway in time to take part in the track activity. It was unclear exactly why this was the case, with some media reports talking about unconfirmed contractual problems between Dragon and Lotus.
Bourdais is now expected to take part instead in the second block of testing on Thursday and Friday with his team mate Katherine Legge. The other 14 cars scheduled to take part in that test include all four Ganassi cars and all three KV Racing Technology cars, including the newly signed Rubens Barrichello.
Before that, the current ten cars will have a second day of testing on Tuesday. The Wednesday will see the track handed over to the Firestone Indy Lights team for their own pre-season test session.
