Ever since McLaren have introduced their new diffuser, the car can again match itself with the best of the field, allowing Hamilton to take 18 points in the latest two races.
Their completely new design built upon the foundations of the double deck diffuser idea. At the same time, the team abandoned its cutout floor after it found out that its effect was far from what was expected after wind tunnel simulations.
At Valencia, the car had additional updates in this area. Notably the exhaust covers were now, for once, symmetrical - contrary to the diffuser's shape.
