Berthon's sprint outing was compromised because of having to start near the back after his early retirement the previous day.
"It's a pity not to have scored a result we had deserved," the French driver - who is in his second year in GP2 - sighed after that engine problem wrecked his feature race. "Right when I was almost sure to end up into the points zone, the engine shut down and I was forced to retire."
On Sunday, Berthon finished only just ahead of Ceccon in Sunday's race 2. "When you take-off from the 22nd place on the grid there's not too much to do to score a great result," he pointed out.
The team had opted to pit Berthon midway through the sprint race and he went on to set the fastest lap on his new set of options, although he didn't qualify for the bonus points because of his finishing position.
That hadn't been the team's target, anyway: "After having been on-track with harder tyres, I decided to come back to the pits and put softs on. The goal was to collect data in order to analyze it for the following races."
Berthon, Ceccon and the rest of the Trident crew will be hoping that the data acquisition bears fruit in the next race of the season in four weeks time in Bahrain and the Sakhir International Circuit on the weekend of April 19-21, and that they will encounter fewer problems and setbacks during the race than they did at Malaysia.
