Anyway, with the Deltawing's racing career over for the year we cannot come to any further conclusions as to why it performs as it does, so we're just covering old ground.

The DW was never meant to adhere to the strict underbody rules of the rest of the grid, hence Garage 56. Remember the the DW was originally conceived as a replacement to the ageing Dallara IR5 IndyCar.
