Programme

The curtain closes on McLaren-Honda’s pre-season preparations. It was a slow start to the morning, but Jenson managed to put some laps on the board during the day. While our test programme has been largely affected by unreliability, and by a lack of running, there’s plenty of optimism that the performance foundations for the partnership are strong, and that development will continue strongly – especially during the early part of the season.

ERIC BOULLIER – McLaren-Honda racing director

“Looking back at the last four weeks, our winter test programme has been difficult. However, that wasn’t entirely unexpected: this time last year, we saw many teams in a similar situation when they introduced new power units for the first time. This year, we also had the added complexity that very tight packaging brings.

“In overview, the lack of mileage means we won’t be as ready as we’d have liked, but we can take away the positive that all the running and data gathering we’ve done have confirmed that we’re achieving the targets we set ourselves.

“Even if it’s likely to be a difficult start to the season, we know we can develop hard and fast, and that we’ll surely unlock the huge potential that lies within the McLaren-Honda MP4-30.”
