Technical Inspection

Technical Inspection

Inspection is conducted of all Verizon IndyCar Series competitors’ cars to enforce regulations and maintain competitive balance between teams and manufacturers. Over the course of an event weekend, INDYCAR officials will conduct five inspections (initial, which includes driver safety equipment; pre-qualifying; postqualifying; pre-race and post-race).

Initial inspection typically includes 15 officials, known as inspectors, and is overseen by INDYCAR technical director Kevin Blanch. Inspection times, based on entrant points entering the race weekend, are provided to teams during the week.

The inspection process includes four stations, which focus on different components of the car. During these processes, inspectors will check – among other items – the mandated safety features, chassis underwing, fuel cell, height, weight and width. 

Laser scanning of the new aerodynamic bodywork kits for road/street course and short ovals and speedways supplied by Chevrolet and Honda is new for 2015.

"Our task is to make sure that the components as homologated don’t get altered by either the manufacturer or team," INDYCAR director of aerodynamic development Tino Belli said. "We want the bodywork run as the aero kit manufacturer designed it and manufactured it."

  • In the safety station, inspectors ensure that the cars meet safety requirements. Among the items checked are the SWEMS (Suspension Wheel/Wing Energy Management System) restraints, driver seat and headrest, seat belts, fasteners, pedal position, steering wheel, helmet, earpieces, fire bottle and the frontal head restraint. Event-specific decals are placed on the car and driver safety equipment after passing initial inspection.
  • At the gauge and template station, inspectors utilize about 60 jigs and templates to measure each car to ensure it meets requirements and conforms to regulations.
  • On the technical inspection pad in the garage area, measurements are made that require the car to be level and sitting on its reference plane.
  • In the laser scanning station, the car exiting the technical inspection pad will be compared to the digital record of the computer-aided design (CAD) of components to ensure no components have been altered.
