Re­nault

In­tro­duced in Hun­gary, Re­nault’s up­dated fron­twing as­sem­bly, which I called the ‘Vene­tian blind’, is just that. Start­ing with the end­plate, the trail­ing edge has five out­ward turn­ing vanes to strengthen the out­wash air­flow in this area. The ver­ti­cal sec­tion of the wing flaps is also slot­ted to im­prove the con­sis­tency of the out­wash flow. The ad­justable in­ner sec­tion of the flaps (yel­low part) is now much smaller. This has a pos­i­tive re­duced flow-char­ac­ter­is­tic change on the out­board sec­tion when the wing an­gle is changed, but also makes it more dif­fi­cult to al­ter the car’s aero­dy­namic bal­ance.
