McLaren is expected to bring a major update to its MP4-31 for this weekend's Spanish Grand Prix. The rate of development has been impressive in 2016: the team has brought updates to the car at every race so far this year.
The Spanish update is another milestone in McLaren's fight back to competitiveness, and it appears the team could have turned the corner with regards to its chassis performance.
Before the Honda partnership began, McLaren's chassis was not at the level of Red Bull and Mercedes. The team had to rebuild its design operation after Paddy Lowe's departure for Mercedes.
