The technical directors at Ferrari and Mercedes are both expecting this year's championship to be decided by small margins.
Ferrari's Sebastian Vettel and Mercedes' Lewis Hamilton went head to head at the opening round of the season in Australia on Sunday, with Vettel coming out on top following a close strategic battle. The two teams appear to be closely matched this year and Mercedes technical director James Allison -- who left Ferrari last summer and joined Mercedes in March -- believes it will remain the same over the course of the season.
"If it wasn't already clear after qualifying, then it's certainly clear now that this is going to be a season of very small margins," he said.
