Caterham team principal Cyril Abiteboul says that their season is developing as expected, despite currently sitting in last place in the championship.
Abiteboul conceded that the Canadian Grand Prix was underwhelming for Caterham, but most other events have met with expectation.
"It’s fair to say our last race in Canada was disappointing, but looking at the season overall we’re probably about where we thought we would be," Abiteboul told The Official Formula 1 website.
"But that does not mean that we are where we want to be! We started the season with a hybrid 2012/2013 car which we’d always planned to use for the first four races. We were able to bring forward some of the 2013 package to Bahrain and saw an immediate improvement there, and then again another step forward in Spain when both cars had additional 2013 parts."
"The simple truth is 2013 was always going to be a tough season, but we are confident we can deliver what we have wanted since the start of the year, which is a clear positive trend towards reducing the gap to the midfield."
Abiteboul also believes that Caterham does not have the resources of some of their rivals, meaning that compromise needs to take place for the sake of next season.
"Our infrastructure and our resources do not allow us to change some of the fundamental and structural characteristics of a chassis that was designed in 2011, raced in 2012 and carried over in 2013, but, as we saw in Bahrain, Spain and Monaco, by focusing on key performance differentiators of the car - the aero package - there are clear signs of progress this year."
"This pragmatic strategy is allowing us to balance the resources we have on the work we can do to keep improving 2013 against the 2014 project, but we have a plan and we’re confident it will pay dividends in the long run. We compete in a championship that lasts nearly 10 months and we’ll judge ourselves at the end of the season, not seven races in."
