After struggling with the power steering system on last year's Lotus T128, Trulli was delighted to find that that, and other areas, had been improved.
“For me, there are a couple of real positives from today," he confirmed, "I hadn't used KERS before and, despite the extra buttons it means on the wheel, it's pretty simple to get used to it quickly. I think we'll see the benefits of that more and more as we keep learning how to get the most out of it.
"Also, for me, the car felt balanced pretty much straight away. The power steering is good – we can keep fine tuning it, but I think it's basically a good package with a lot of potential for us to work on. A good way to start the season.”
Caterham Group CEO Riad Asmat was equally encouraged, but sounded a note of caution, aware that the rest of the field would be pushing just as hard to refine their packages ahead of the opening round in Melbourne in five weeks time.
“Jarno ran another very impressive number of laps today and, when you look at the total mileage we have accumulated here, we have clearly started the season with a good, reliable car," he noted, "We know there is pace to come, but we also know we have a lot of work ahead of us to make sure we arrive in Australia in the strongest possible position.
"This week, we have had the best start to a season yet in our three short years, so we will move on to Barcelona in good spirits, with more new parts to come and in good shape to keep unlocking this car's potential.”
