The upgrades brought to the Monaco Grand Prix by Renault used three of their available tokens, it was announced on Saturday.
The power unit upgrade that was first tested during the post-Spanish Grand Prix test at the Circuit de Catalunya earlier this month by both the Renault Sport F1 and Red Bull Racing teams was highly praised by all drivers, with both Kevin Magnussen and Daniel Ricciardo getting the benefit of the engine this weekend.
The use of just three tokens to improve the driveability of the engine means Renault still have twenty-one tokens available to them to develop the power unit during the season, which bodes well with how improved the engine already seems to be.
“You need to completely disconnect usage of tokens from performance,” said Renault’s Cyril Abiteboul to Motorsport.com.
“You can use all your 32 tokens or whatever without creating any performance, and with one token you can have one magic bullet which is creating a lot.
“With what we have understood now we now have a ratio of performance per token which is much higher than last year.”
Honda has fourteen tokens remaining to them for their engine development, while Mercedes has eleven and Ferrari only six.
