Lotus have really struggled to realise the potential of the E22 this season with issues from the Renault power unit causing their fair share of these. However a complex asymmetric design was also bound to be fraught with issues too and makes aerodynamic changes even more difficult.
In Hockenheim the team arrived with a new front wing, looking to gain balance and performance. The old wing above can be seen above whilst close images of the new wing are scarce, Giorgio Piola did manage to grab a shot of it in a similar orientation whilst it was in the garage (shown below)
Meanwhile at the rear of the Endplate the bottom section has been removed, allowing airflow to traverse from the flapped region across the footplate. Of course both changes have been made to entice the airflow around the front tyre, creating a stronger flow structure that can impact the tyres wake, increasing the floor/diffusers performance.
