It may still just exist at the mock-up stage, but Ben Bowlby's DeltaWing group is building publicity for its radical Indy car chassis concept – currently among the proposals being evaluated by the Indy Racing League's ICONIC advisory committee – via video simulations. DeltaWing has released a new simulation video of a group of its cars racing at the high-banked Texas Motor Speedway, utilizing full rFactor Driver-in-the-Loop simulations.
"The DeltaWing's mass properties, aerodynamic downforce, balance and yaw-sensitive maps, aero traffic effects, tire characteristics, suspension geometry, engine maps, gearshifts and differential are as realistic as we can make them based on the simulations and aero testing conducted by DeltaWing thus far in the development process," DeltaWing said in a statement accompanying the release. "While there are, of course, some detail limitations, we believe they do not change the overall impression and handling of the DeltaWing cars as shown in the videos."
The DeltaWing is vying with alternative proposals from BAT, Dallara, Lola and Swift to become the next-generation Indy car chassis. The advisory panel is currently considering the merits of each design, as well as the positive and negative aspects of restoring chassis variety or retaining the current de facto spec chassis format for the IZOD IndyCar Series.
