Jenson Button is hopeful that McLaren-Honda has overcome the problems that have plagued it over the opening two days of testing at Jerez.
Button completed just six laps on Monday after the issue that limited Fernando Alonso to just six laps on the opening day resurfaced.
McLaren attempted to rectify the problem, but lost most of the day’s running hunting for a fix, with Button completing just a handful of installation runs in the MP4-30.
“We expected this test to be tricky – and the next two days probably won’t be plain sailing, either,” he said.
“But people have short memories. Look at last winter – the first test of 2014 was very tough for everyone too. So there are no real worries at the moment.
“We’re just hopeful we’ve solved our issue – the last run of the day seems to have sorted the problem out, so I hope tomorrow will be a little easier.
“It’d be nice to get some laps on the engine, and to begin to find out where we are in terms of engine driveability and car development.”
Despite the early teething problems with the new car, Button says there are plenty of early positives to take from the first two days of running in Jerez.
“This is a very complicated power unit, but its packaging is unbelievable – very tight – and we haven’t had any temperature issues,” he added. “That’s a massive positive for us, so well done to Honda for that.
“There’s a very positive atmosphere about the place: the team isn’t McLaren and Honda, it’s McLaren-Honda. It’s everyone together.”
Fernando Alonso will return for McLaren on Tuesday for his final run in the MP4-30 in Jerez.
