While you begin with a brand new automotive, or with a brand new specification – just like the producer aerokits in 2015 or once we went again to a common aerokit in 2018 – your focus is on driver consolation initially, and then you definately decide that are the areas for enhancing efficiency.
Clearly we’ve had this automotive for some time so, unloading on the Speedway, we have already got a good suggestion of the place to start out when it comes to set-up, the place we would discover additional tempo, and in addition methods to dial every automotive right into a driver’s explicit preferences. Final 12 months at Indy, there wasn’t a ton of variance throughout our six vehicles, however there’s all the time three or 4 issues that Scott Dixon likes totally different from Marcus Ericsson, and that Marcus likes totally different from Alex Palou.
And issues change yearly. We are able to’t return to Indy with the identical set-ups we ran final Might. There have been aero modifications to the vehicles by way of the laws for 2023, methods to unlock extra downforce – probably extra for race set-up than qualifying.
Wind and climate modifications are infamous for having an enormous impact at Indy. Partly that’s as a result of you’ve a lot observe time in contrast with different races, you may get your automotive nearer to the sting, and partly it’s as a result of small modifications make such a large distinction at these speeds. It’s necessary to make use of observe time to determine all the small print for making minor modifications in response to observe situations and nonetheless hold the automotive within the window when it comes to dealing with and velocity.
With the brand new items IndyCar has allowed us this 12 months, based mostly on the aero testing that we’ve seen, we predict now we have a reasonably good concept how we wish to run the automotive and the place we predict most efficiency shall be, however on-track outcomes can all the time be a bit totally different from wind tunnel knowledge. In order a staff, we are going to divide the duties amongst our 4 entries – one works on variables on this space, one other works on variables in one other space – after which we are going to debrief collectively on the finish of first observe, revisit the issues we’ve found, and transfer ahead in what we hope shall be a productive approach the subsequent day.
Regardless of the situations, automotive set-up is vital to a profitable Indy 500, and infrequently dictates over a driver’s preferences

The factor is, we will’t keep nonetheless. Even with out the brand new aero items, we might have labored simply as arduous as this low season on Indy set-ups as a result of any benefit you’ve doesn’t final lengthy. So getting all of the areas lined in observe by 4 actually skilled drivers – three of them Indy 500 winners already – is massively necessary.
Come qualifying, the order through which every entry makes its first run is determined by draw on Friday night. So we may have one in every of our drivers operating first in line, and one in every of them making his run 34th: which means their runs may very well be two and a half or three hours aside, so what labored for the primary man is nothing like what would possibly work for the final man. We’ve got predictive knowledge for ambient and observe temperatures, and it’s that, fairly than driver preferences, that may trigger the largest variations in set-ups for these first runs.
For race set-ups, you’re all the time looking forward to the final couple of stints, what the observe temp goes to be, predicting how the steadiness of the automotive goes to alter, and hold forward of that
Then as soon as all 34 vehicles have gotten their first runs out of the way in which, if you wish to make additional runs – and also you often do, particularly in case your first run was a bit conservative – you get the possibility to regulate for observe situations with every.
For race set-ups, you’re all the time looking forward to the final couple of stints, what the observe temp goes to be, predicting how the steadiness of the automotive goes to alter, and hold forward of that. Generally that may imply you run a set-up that makes the automotive a little bit of a handful within the first stint however will get higher as extra rubber goes down. Different instances, if the anticipated observe temperatures are excessive from the start of the race, you would possibly begin with extra downforce, then if grip ranges come up later, you could possibly trim out for the ultimate stints and hopefully push for the win.
