IndyCar XIC – a path to the future

Here is the plan that Derrick Walker – IndyCar's ex-president of operations and competition – was due to present to team owners in July this year, that would have seen a new car introduced in 2018.

However, the presentation was delayed and finally binned, as Walker was told that many owners didn’t want to spend money on new cars. He was willing to modify the timeline to introduce the cars in 2020, but it wasn't long after being spurned that he decided to walk.

Nonetheless, he remains a fan of U.S. open-wheel racing and elected to share his presentation with Walker still believes the XIC project or something very akin to it, needs to be implemented for the series to become more popular, more successful and more relevant.

In this writer's opinion, Walker is a visionary but also a realist; he's someone with common sense and an idea of how to fulfill ambition in a logical and practical manner. Relieving him of some his other duties in order to manage this major project would have been a smarter move than merely accepting his resignation. 

See if you agree. We look forward to reading your comments. 


  • Planning for the future is now. The decision to build the next generation open wheel car needs to allow at least two year lead time before entering competition.
  • The goal would be to continue to improve the quality of our racing and push the borders of innovation and safety within our limitations.            

The Concept

  • Advanced fan and driver safety
  • Planned eight year competitive life span (with updates)
  • Cost containment with continuation of component availability
  • Standard car platform with limited optional aero components
  • Limited team development with approval
  • Third-party development, two years after car launch
  • Grandfather the DW12 for one year (if required)


The essentials are: Appearance • Safety • Affordability • Technology • Raceability • Adaptability • Availability • Performance 


  • A futuristic and timeless design
  • An easily identifiable unique Indy car design
  • Designed as an Indianapolis 500 car that is adaptable for road and street courses
  • Optional components to provide a variety of shapes and performance choices – supplied with the standard car
  • Third-party aero development permitted after two seasons
  • Exhaust design options permitted for sound variations 

Safety improvements

  • Advanced driver cell – next breakthrough in safety
  • Improvements in component retention
  • Frontal cockpit design to improve driver protection
  • Advanced side impact driver protection
  • Further reduction in lift issues
  • Eliminate steering wheel whiplash effect


  • Complete car price of $450,000. Supplied in super speedway configuration with road and street course conversion parts and optional components

  • Series control unit (car and engine data/management) 


  • Reduction in draft turbulence and further avoidance of pack racing tendency
  • Less reliance on downforce generated from aero foils
  • Large reduction in the maximum downforce level
  • Robust body design manufactured with fewer parts to reduce yellow flags and permit close wheel-to-wheel competition
  • Increase the engine power to downforce ratio


  • An adaptable design with easily-adjustable performance levels and a variety of component options for a wider range of tuning
  • Third-party development can use or modify any approved component for the avoidance of unnecessary obsolescence
  • All original components and optional parts shall remain current during the lifespan of the car
  • An adaptable design that can accept future engine/power unit configurations    


  • Car components, regardless of manufacturer or function, shall be required to be made available to all competitors
  • Component design information and technical data shall be required to be made available to all competitors
  • Component development by third-party designs shall only be manufactured by approved suppliers
  • Power units permitted to compete must be available to all competitors without exception 


  • Big overall car weight reduction
  • Optimum weight distribution options
  • Engine power output increased by 10 percent
  • Underbody development with reduced wing dependency
  • Increased vehicle acceleration
  • Overall drag reduction by limited movable aerodynamic surfaces and/or openings  

Standard platform

  • Standard car platform utilizes common components from the registered manufacturers/suppliers:

Transmission/driveline (5-speed) /  Gearchange system / Power steering / Brakes and dampers / Wheelbearing assemblies / Fuel cell / Refueling system / Dashboard electronics and wiring

  • Conversion parts for road and street configurations to be included with the standard car

Optional components

Standard car platform is supplied with the “Optional Components”

For example: Front end-fences and strakes / Wheelbase / Rockers / Sidepod and radiators / Speedway rear pods / Wheel inserts / Engine cover / Brake ducting

Third-party components

  • Third-party component development through an open-source process in year two after the new car introduction
  • Creation of a practical system to manage component change    
  • Entities submit designs for approval through an open-source process.  Once approved, components would be supplied only by approved manufacturers
  • All car design information is shared and is price-controlled  


  • STANDARD CAR PLATFORM (2018): $350,000

Oval car with road/street conversion parts


Aero and suspension body components      

  • All components remain current for the life of the car
  • All optional parts and future third-party development components must be interchangeable with the standard car platform
  • A percentage of all car and component sales will be set aside for a safety development fund
  • (To re-emphasize - Third-party components shall come through an open-source system and would not exceed 120 percent of the original part price)


  • Committee of six members (three IndyCar Series, three advisors)
  • Sub-committee involvement when required 
  • Dedicated purchasing and sales person 
  • Quarterly team owner update meetings, monthly update reports
  • Timelines and deadline action plan  
  • Contracted with manufacturers and suppliers

December 2015 - Complete the business plan and agreements
January 2016 - Design and manufacture begins
June 2016 - Design, manufacture and prototype testing
January 2017 - Testing and manufacture
