Honda have confirmed they have spent two tokens to update the turbo for this weekends race in Montreal.
Canada is the first of the ‘power’ circuits this season, where Honda have been left behind since they re-entered the sport 18 months ago. Instead of a horsepower boost, the upgrade to the turbo will be primarily to increase the energy harvesting.
Both Jenson Button and Fernando Alonso will get the upgrade, unlike the route Renault took introducing two revised power units in Monaco, before the final two arrive in Canada. It gave the opportunity for them to test the upgrades in an environment which isn’t power sensitive.
It leaves Honda with 11 engine tokens remaining this season, with Ferrari also spending two tokens for Canada leaving them on just four for the rest of the season. Mercedes have 11 remaining and Renault 14, even after their major upgrade.
