PRO­PELLED BY THE WIND BE­NEATH ITS WINGS

Mercury (Hobart) - Motoring - - PRESTIGE -

What is Aero­d­i­nam­ica Lam­borgh­ini At­tiva? The se­cret to the Aven­ta­dor SVJ’s rear wing is a two-piece flap­per valve be­neath the cover of its rear-mounted en­gine. Here speed pushes air into a for­ward-fac­ing, mesh-mouthed duct. With the valves open, this air rushes through the rear spoiler’s cen­tre pil­lar, then is guided to slots cut in the wing’s un­der­side. This air­flow re­duces the ef­fect of the spoiler, cut­ting aero drag and so in­creas­ing top speed. For cor­ners, ALA opens only one side of the two-piece valve, cre­at­ing pres­sure on the tyre on the in­side of the curve, but not the out­side tyre.
