Tech analysis: other challengers
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.
