Renault opt for 2005-style front wing
Although it's starting to look rare these days, Renault ran an unstacked front wing to fit the lower drag requirements at Montreal. The upper elements were removed, making the front wing look more like an item from 2005. The team also dropped their mid wing for this race and most likely will retain a similar configuration for the Indianapolis race. While it is visible, note the little gurney flap at the trailing outer edge of the wing. This effectively creates more downforce at the wing's outer extremities while preventing flow separation on the underside.
A strange development I\'d have thought...
