Marussia team principal John Booth believes that his team can take the fight to the midfield runners.
Jules Bianchi and Max Chilton finished fifteenth and seventeenth respectively in last weekend's Australian Grand Prix.
"The out-of-the-box reliability and performance of the MR02 has been very pleasing to see, especially as the car is quite a significant evolution of the MR01 and we have had to make the necessary modifications to accommodate KERS for this season," said Booth.
"Having said that, one race does not make a season and we will need to work hard, particularly in these early races, to continue to take the fight to the midfield, which we have shown to be a target realistically within reach. Up and down the field, every team will be aiming to make progress and keep developing their package, so we need to maintain our current momentum."
Lead driver Bianchi says he is looking to learn from an impressive debut race.
"This week I have had the chance to think everything through - what I have learned and where I need to go from here. I had a good debrief with my engineering team and I feel very comfortable, so now I start to think about Malaysia," said the Frenchman.
"I’ve done some work in the simulator and I think Sepang is a circuit I’m going to enjoy. I know the challenge it brings in terms of the heat and humidity, so I’m prepared for that. Although my debut went well, there are some areas that I need to work on and where I can improve – as you would expect – so this race we will have a little more time and experience to think about what we need to do to keep pushing forward."
