Mercedes team principal Toto Wolff has said that although the team's pace throughout the United States Grand Prix 'wasn't enough for victory', they should be proud that their development is progressing in the right direction.
"It was the fastest car," Wolff told Sky Sports Germany.
"It wasn't enough for victory, but it was enough for a duel on equal terms with Red Bull.
"You shouldn't forget that they probably completed the development of the current car three months ago and are already looking ahead to next year. That's right, however, we now have another one.
"We've brought a big upgrade. The development direction is right. We wanted to see whether the subfloor worked."
