Redesigned exhaust system for McLaren

By on

McLaren is pushing ahead with its car development, and this time has come up with a revised aerodynamics package around the exhausts. The change resembles much that of Renault or Ferrari early on in the season as they decided that it is better to let hot air out of the sidepod sooner rather than later. Hence McLaren did the same, as the exhausts are now part of a large air outlet opening, following which the car's shell is much more tight. Still, the system is assymetrical with the left side allowing more hot air to exit.

Also marked it the revised engine cover which Hamilton already had at the Nürburgring. The previous version that was used without change in the first half of the season is now replaced by a more traditional layout with a straight slope towards the rear crash structure. The change effectively reduces the surface of the cover and is an opposite development of the extending shark fin covers.

Also, the cut-out from the floor is gone, as of the Nurburgring.

Hi, I'm new here.. I think this is the site for me.

So yes about the new Mac exhaust .. but what about the new asymmetrical diffuser? Maybe done to create an sidewards-pulling wake for a following car?

It's because of the starter-hole in the gearbox, it's off-center.
