INDYCAR adjusts superspeedway aerodynamic tuning options

This afternoon INDYCAR, the sanctioning body of the Verizon IndyCar Series, announced that teams will have additional tuning options at their disposal for the August event at Pocono Raceway.

Following an Indianapolis 500 that produced scorching-hot temperatures and less-than-favorable passing conditions, INDYCAR and Dallara have teamed up to offer a solution to the passing woes experienced at Indianapolis.

Ahead of the race in the Pennsylvania mountains, teams will have the ability to add more downforce to the speedway front wing configuration than was previously offered.  This comes as a result of Dallara producing a front wing extension (pictured below) that will attach to the trailing edge of the main plane.

Teams are not going to be required to run this additional piece, but with the limited options available to the rear wing configuration it at least gives crews a chance to get creative with their sets and differentiate from the competition somewhat.

The same holes on the wing main plane that were previously used for wicker attachment will be the new fastening locations for Dallara’s new wing extensions.  Additionally, teams will have the chance to attach a wicker to the front wing extensions just as they have done earlier in the season on the main plane.

As seen for the Indianapolis 500, asymmetrical wicker set-ups were the most common and effective way for teams to counter the lack of effective downforce in hot weather conditions.  With this wing extension, teams will have the ability to attach pieces asymmetrically in order to fine-tune to a driver’s personal feel.

Many teams have run more wicker on the left side of the wing than the right in an attempt to pull that corner of the car into a turn at speedway events in 2018.

According to INDYCAR, with the extension fitted in its full configuration it can generate up to 3 percent more front downforce than the previous aero options could produce.  The sanctioning body is telling teams that the adjustments will add downforce while still ensuring “adequate aerodynamic stability.”

The creation of this “fix” comes after driver and team input was gathered following the Indianapolis 500.  This piece was in development before the most recent Verizon IndyCar Series race at Texas Motor Speedway on June 9.

While the teams of IndyCar will visit the 0.875-mile oval in Newton, Iowa before they traverse to Pocono’s 2.0-mile track, the Pocono race will be the first event featuring the new configuration as it is the next (and final) superspeedway on the calendar.

The ABC Supply 500 will go green on Sunday, August 19 from Pocono Raceway.  The event will be televised live on NBCSN with the green flag scheduled for 1:30 p.m. Eastern.

IndyCar Radio will offer a live radio feed of the race as well, so check local listings to find an affiliate near you.
