Mercedes, Red Bull and, for this example, Williams have come up with very short nose designs to their 2015 cars – resulting in the front wing mounted further ahead of the nose. This gives the look that the nose cone pylons are barely making contact to support the entire front wing, especially under load.
This is in fact an optical illusion; the nose cone pylons don’t actually connect directly to the front wing – they connect to extrusions that are formed directly into the main plane that sit further back. This allows for the pylons to make suitable contact to support the front wing, despite the look of being very fragile.
Both Williams and Mercedes used a less extreme version of this last season on their 2014 cars.
