Honda will introduce an engine for Spa using some of its remaining development tokens. Honda chief, Yasuhisa Arai, explains where Honda is at.
“I am confident our reliability problems are now behind us which means we can turn our attention to increasing power.
“The most important area for us to concentrate on is the combustion.
“Current regulations require high efficiency of the combustion so we want to change the characteristic with the chamber design and intake and exhaust system layout.
“Another issue we will be addressing is reducing mechanical friction by changing the gear-train system along with the combustion.
“Not all of our upgrades will be in place for the Belgian Grand Prix; some parts will be applied for Spa and the rest during the weeks that follow.”
Arai interestingly reveals the cycle of problems Honda has been experiencing.
“If you try to harvest energy using the MGU-H, it puts a strenuous workload on the turbo.
“When the turbo is under stress, it cannot do what it is supposed to do, which is to force more air into the engine, thus leading to decreased power output.
“This is the result of one component working against the others, instead of working together.
“These types of technical chain reactions which lead to vehicle stoppage were definitely more than we calculated, or more than we envisioned.”
The reality is McLaren-Honda have over promised and under delivered, though as Renault have gone some way to demonstrate – solving reliability problems is the first step on the ladder of progressing up the grid.
The big question with 9 races to go is – whether McLaren Honda can fight for fifth place in the F1 constructor’s title
