Honda will give an upgraded engine to its Red Bull and Toro Rosso teams at this weekend's French Grand Prix.
Three of the company's four drivers will have the engine - Red Bull's Max Verstappen and Pierre Gasly and Toro Rosso's Daniil Kvyat.
The move means a grid penalty for Kvyat for exceeding the permitted usage of engine parts in a season.
Toro Rosso's Alexander Albon will upgrade at a later date to avoid both cars incurring penalties at one race.
Honda boss Toyoharu Tanabe said the engine was more powerful but had not yet reached the level of Mercedes and Ferrari.
