Honda is not resting in its efforts to close the gap to its power unit rivals.
Christian Horner revealed recently that Renault is now less than 50 horse power behind field-leaders Mercedes and Ferrari.
McLaren’s works supplier Honda has also improved markedly in 2017, and another step is coming soon according to team driver Jenson Button.
"We have the summer break and then Spa (the Belgian GP), where we will have another update for the power unit, which is exciting," the Briton is quoted by the Spanish sports daily AS at Hockenheim.
The steps made by Honda and McLaren this year have also been welcomed by Fernando Alonso, who thinks he is performing better as a driver compared to 2015.
"Last year I was not comfortable, not happy with my own performance," said the Spaniard.
"But this year I’m driving at my best level," he added.
