LAS VEGAS ACCIDENT REVIEW COMPLETE
INDIANAPOLIS (Dec. 15, 2011) - A comprehensive review of the racing accident
that claimed the life of Dan Wheldon is complete, INDYCAR announced Dec. 15.
Wheldon, the 2005 IZOD IndyCar Series champion and two-time Indianapolis 500
winner, suffered a non-survivable head injury Oct. 16 in a 15-car crash in Turn
2 of Las Vegas Motor Speedway during the final race of the 2011 IZOD IndyCar
Series season.
"There are multiple factors that are not uncommon to racing that came together
in a way that claimed Dan's life," said Brian Barnhart, President of
Operations, INDYCAR. "It is a tragedy. Our thoughts and support will always be
with Dan's family."
The accident review revealed that Wheldon's path on the lower portion of the
racetrack was blocked by the multi-car crash he was approaching. The No. 77 car
became airborne and ultimately impacted a vertical post of the track fencing.
The pole intruded the cockpit, and the impact with the driver's helmeted head
produced non-survivable blunt force trauma.
The response to the scene by INDYCAR's Holmatro Safety Team was
rapid and decisive, according to the review.
INDYCAR analyzed data from the accident data recorders carried on board each
race car involved in the crash, the on-board data acquisition system from
teams, timing and scoring data, video, still photographs, physical evidence and
eyewitness reports from participants. Third-party experts with
Indianapolis-based Wolf Technical Services provided independent assurance that
the investigation protocol, evidence examined and reviewed, and the conclusions
reached are consistent and appropriate to standard scientific and engineering
investigation methods.
Examination of video of the incident demonstrates normal "pack racing" that is
common on high-banked ovals. However, there was almost unlimited movement on
the track surface under race conditions not previously experienced that is
attributed to track geometry beyond banking. Such freedom of movement outside
of normal racing grooves not only increased the probability for car-to-car
contact, but made it more difficult for drivers to predict the movement of
other drivers. As a result, the opportunity for this incident was increased.
While this incident could have occurred at any track at any time,
the dynamic of the current car and the overall track geometry at Las Vegas
Motor Speedway under race conditions appears to have been one of the
contributing factors in this incident.
The 34-car starting field was determined to be acceptable based on factors such
as length and width of the racetrack and pit space capability. This incident
and its consequences could have occurred with any size starting field at any
track.
"INDYCAR's commitment to safety was enhanced by Dan Wheldon's testing
throughout 2011 of the new car to be used by INDYCAR in 2012," said Randy
Bernard, CEO, INDYCAR. "The 2012 IZOD IndyCar Series season ushers in an era of
a new race car and the opportunity for continued safety advancements. Dan
Wheldon was instrumental in the testing and development of this new car and the
safety innovations that it represents. We are thankful for his efforts and
commitment to racing."
The 2012 Dallara Automobili chassis enhances safety components such as side
intrusion panels and wheel tethers. The cockpit is longer and wider than the
decommissioned monocoque, which allows for additional padding underneath and
behind the driver. Also, a "floating headrest" works in conjunction with the
mandatory FHR (Frontal Head Restraint) attached to the helmet. Driver
positioning allows for better sightlines.
