What is this & has anyone seen it on a Jag?car before?
Saw this on another Jag Forum and have no idea the purpose of the front underneath attachment. Looks ugly, but what the purpose or practical use thereof?
Theoretically, it produces downforce for better traction. The air pressure of the much slower moving air on top of it is higher than the pressure of the air flowing more freely below it. I'm not an engineer. I just remember back in the 80s when so many cars started coming with optional air dams, skirts and spoilers. While sitting in a doctors office once upon a time I happened across an interesting article. I don't remember if it was Car & Driver, Popular Mechanics or which, but they had wind-tunnel tested like ten different cars with optional OEM ground effects and concluded that some of them did produce downforce and all of them increased drag, but that there was nowhere in the United States that it was legal to drive fast enough to get more than about five lbs per corner and thus they hurt more than they helped. They were all basically just an option to make the stock consumer vehicles look more like their factory race cars. Indeed, at the time, my Mercury Capri RS kinda reminded a very young me of the ones Roush was campaigning in Trans Am. I'm sure whoever drives the one pictured imagines himself whipping around Brands Hatch just like his favorite British Touring Car Championship driver and that's well worth sacrificing one mpg.
