Chilton was ninth on Day 3 in Jerez.
“I’m really pleased with how my second day in the car has gone and I’m happy to have been able to reveal a little more of the car’s potential,” he said.
“Obviously these are very early days for all of us, but there are some very positive signs and I’m excited about that”.
“The race runs went very well and we’re starting to understand how the 2013 tyres are going to wear. Having completed the long run work we needed to, it was nice to have a new tyre run at the end of the day to explore more of the car’s performance. What we found was very encouraging and this has given the Team a nice boost at this early stage of the MR02’s development.”
Team principal John Booth praised his young charger.
“Credit to Max for another great day’s work. It hasn’t been easy for either driver so far, but Max has responded well. He clearly appreciates the highs and lows which go with testing and he has applied himself well as the Team worked to resolve the teething issues,” he said.
Luiz Razia tests for Marussia tomorrow.
