McLaren confirms that they will not repeat gearbox problems, last race weekend at Singapore GP both McLaren guys are troubled with gearbox problems, the failure happening in Hamilton’s car and following he was retired from the night race.
Last week McLaren confirmed that Jenson Button also struggled with gearbox problem during the Marina Bay night race, but he finished second place and they decided to change his gearbox unit, with get five-place grid penalty for this weekend at Japanese GP.
McLaren technical director Paddy Lowe claim that it was a quality control problem, and now fixed this and confirms not repeat the issues.
“It was the same [problem] on both cars actually, just more extreme in Lewis’s car so it was then terminal Button was, to be honest, quite lucky to finish, and the gearbox was not in a good state at the end. So that is why we had to change it.” Paddy Lowe said
“It was a quality problem that unfortunately affected both of those gearboxes, but we completely understand it now and it won’t crop up again. It had affected a certain batch.”
Paddy Lowe added that several teams struggled with gearbox failures this season, one single unit gearbox permitted to use for five grand prix event.
“It is very difficult, as you can appreciate, to build a new gearbox each year in a very limited amount of time, and type approves it to run five races uninterrupted. In our case, committing to it across two teams [McLaren also supplies Force India] is a big pressure on the system.
“It is tough, and what is making it [particularly] tough these days is the programme demand and timing of that in relation to the high endurance that is needed. It is quite an unforgiving set of rules in relation to penalties.”
