Lotus have introduced a new bodywork package on their E21 which appears to be a lot skinnier ahead of the rear wing. While Raikkonen was still running the old package, a few times even with DRD, Grosjean's E21 had this new package which looks unsuited for DRD, even though the inlets are still present.
One of the most interesting bits is the outlet of the sidepod's hot air. Where most teams aim to dump that close to the floor or through a Red Bull style funnel ahead of the monkey seat, the new Lotus package features a shallow triangular shape, blowing air onto a wide central section of the beam wing. Its shape appears to be designed to remove any obstacles in the airflow higher than the sidepod's shoulders. This in return should increase the efficiency of the rear wing.
