Today s Indy cars look drastically different than those that ran in the first Indianapolis 500 in 1911, and that has a lot to do with the series aerodynamic advancements.
The Verizon IndyCar Series has a video showing just how much slipperier cars have become throughout the decades, and take this as a warning: nerdy Computation Fluid Dynamics lies ahead.
The Automotive Research Center, or ARC, in Indianapolis decided to run some Computational Fluid Dynamics simulations used to predict fluid behavior on four Indy cars—a 1911 Marmon Wasp, a 1955 Kurtis Kraft 500C, a 1965 Lotus 38 and a 2011 Dallara—to see just how much better the newer cars are in the wind tunnel versus their predecessors.
Of course, designers back then didn t have the tools we have today to simulate fluid flow, so we can t be too hard on the engineers.
He also says the rear of the car makes no downforce at all, and that the front actually produces lift!
The car also produced zero downforce, which could make cornering a bit hairy.
