Supercars to strengthen Gen3 chassis

Supercars to Strengthen Gen3 Chassis

By Thomas Miles

Supercars has announced changes can be made to strengthen the Gen3 chassis after some worrying signs emerged from the first two rounds of 2023.

Ever since James Courtney was surprisingly ruled out of race 2 at Newcastle following a Shootout crash, the majority of the paddock has come to the realisation the new Ford Mustang and Chevrolet Camaro chassis are more susceptible to damage than their Gen2 predecessors.

The decision was signed off by the Supercars Commission and Technical Working Group this week, with the changes believed to be optional ahead of round 3 at Perth.

Supercars stated the unspecified changes have been made as a measure for “continuous improvement” of Gen3, which claims is a “similar” experience to the roll out of Car of the Future in 2013.

“The Technical Working Group approved some modifications to the front and rear clips, and chassis, to improve the impacts of damage learnt from the Albert Park findings,” a Supercars spokesperson said.

“This is a process of continuous improvement similar to what the series went through the last time it introduced a new platform.”

The news will be a welcome relief to Tickford team principal Tim Edwards, who said Supercars had to act after the Australian Grand Prix.

“I do not believe we have time to wait on this. We have got to get on top of it now,” he said in the latest issue of AUTO ACTION

“I do not know whether it needs to be stronger or in a slightly different style, but roll the clock back a decade to the first year of Car of the Future we had accidents and changed the wall thickness of some of the tubes in the front.

“There have been multiple accidents and several chassis have been damaged. 

“It needs to be looked at sooner rather than later. 2024 is not going to be soon enough.”

Courtney was the first to crash test a Gen3 car, hitting the Turn 7 concrete and many were surprised to see car #5 not on the grid for that afternoon’s race.

The worrying signs became clear for all to see at the recent Melbourne SuperSprint where many teams were tasked with extensive repair jobs.

These arrived as early as opening practice where both Tim Slade and Shane van Gisbergen were ruled out of the subsequent session in order to repair the damage.

Van Gisbergen’s was the most surprising having endured a spectacular spin, but avoided major contact with the wall. The Kiwi was seen on the tools himself repairing car #97.

Slade suffered a much bigger crash at Turn 5, with significant damage forcing PremiAir to perform “a miracle” to get his #23 Camaro ready for that afternoon’s race.

“This is the first time we have damaged it (a Gen3 car). It does not seem to be as strong as last year’s car and we are still trying to get our heads around that,” PremiAir Racing team principal Matt Cook told AUTO ACTION after Slade’s smash.

“If it looks bad on the outside, it is normally 10 times as worse on the inside.”

Both Slade and van Gisbergen sustained damaged clips, while the likes Macauley Jones, Mark Winterbottom and Jack Le Brocq also suffered the same fate later on during a dramatic weekend.

Most surprising of all was Jones, who bent his chassis after an innocuous brush with the wall in Thursday practice.

They’re proven to be softer than what I guess they probably first imagined!” He said on the Brad Jones Racing RunDown podcast.

“I had some contact on Thursday, I got caught out in that first session and hit the wall side on…it wasn’t a huge impact.

“And it didn’t do any damage to any of the arms, or any of the uprights. So it didn’t do any actual damage, and I didn’t do any panel damage. But it had bent the clevis in the rear clip, quite a lot actually!

Teams will be hoping the chassis stay strong at the Perth SuperSprint, which should come as a welcome relief being the first dedicated race track after two concrete-lined street circuits opened the season.
