London - Mercedes has found the computer bug that killed Lewis Hamilton's victory hopes at the season-opening Australian Grand Prix and the team has also taken steps to ensure it does not happen again.
Trackside engineering director Andrew Shovlin said in a debrief on the Mercedes website that the problem was not what had been originally suspected after Sunday's season-opening race in Melbourne.
"The issue isn't actually with the race strategy software that we use," he said. "It was an offline tool... and we found a bug in that tool that meant that it gave us the wrong number."
Shovlin explained that the tool was used to create delta lap times, in this case the difference between Hamilton's car remaining on track under virtual safety car conditions while Ferrari's Sebastian Vettel pitted.
"It's never quite an exact science because you don't know how fast a car is going to be able to come through that pit entry, you don't know quite how closely they'll stick to the delta," Shovlin added.
