The Honda Super Speedway Aero Kit, produced by Honda Performance Development, Honda’s racing arm in North America, includes a variety of individual aerodynamic components fitted to the existing Honda-powered Dallara Indy car chassis. All are intended to give Honda’s six Indy car teams – encompassing a potential 17 ‘500’ entrants – the ability to maximize performance at the 2.5-mile Indianapolis Motor Speedway oval and other large ovals ( over one mile in length) on the 2015 Verizon IndyCar Series schedule.
Honda’s Indy car aero kits were developed by utilizing the latest in Computer-Aided Design (CAD) and Computational Fluid Dynamics (CFD) technology, then validated using Driver-In-Loop (DIL) Simulators. This process minimized waste at the prototype stage, and allowed aerodynamic direction to be determined prior to the creation of full-size components.
Full-scale wind tunnel testing was used to confirm actual aerodynamic performance characteristics and create aero maps to be used during on-track testing. Final proof-of-concept correlation then took place with on-track testing prior to the start of production earlier this year.
The complete Super Speedway Aero Kit provides Honda drivers and teams with a range of configurations to tune the cars to their desired characteristics for Indianapolis, a circuit where fine-tuning is essential to achieve optimum performance.
On the other side of the grid, Chevrolet too introduced its speedway aero kit to be used on high-speed ovals in the 2015 Verizon IndyCar Series – including features developed exclusively for running the Indianapolis 500.
The speedway configuration, which was developed in conjunction with the road course configuration, emphasizes the low-drag attributes that enable Chevrolet race cars to achieve speeds of more than 230 mph at the Indianapolis Motor Speedway’s famous 2.5-mile oval.
Highlights of the new design include:
– Unique mainplane surface contour serves two purposes, the inboard section directs air to the radiator inlets to enhance engine cooling while the outboard section creates airflow around the front tire to minimize drag.
Engine cover and side pods
– The engine cover and side pods are shared with the road course configuration, but are optimized in their speedway configuration by adding close out panels to their trailing edges to reduce drag.
– Louvers in the side pods provide cooling benefits and clean airflow to the rear of the car, delivering higher levels of diffuser and rear wing efficiency.
– The wheel wedge configuration is fully adjustable, providing various levels of downforce and efficiency to meet changing track conditions.
Rear bumper pods
– The rear bumper pods and wheel wedges were designed as an integrated solution to reduce vehicle drag.
– A high-efficiency upper rear wing, unique for the Indy 500, features low-mass rear wing pillars and a low-mass rear mainplane.
Chevrolet race teams will compete with the road course aero kit on May 9 for the Angie’s List Grand Prix of Indianapolis, on Indy’s infield road course, before converting their cars to the speedway aero kit for the Indianapolis 500 on May 24.
