The chassis are identical and think a majority of the parts are as well. It's the fine tuning that makes it an oval car. It's the seams, massaging the bodywork so it's as smooth as possible, the bearings, making sure they are absolutely perfect, the shocks, the package must be perfect and spot on. It sounds like most teams started on the oval car over the winter and built it from the start for Indy. You'll never get that time back, especially shown when you look at Kaiser at the sharp end until that car was wrecked.

So much of that sounds like bolt-on parts that you would have spares for, and which could be bolted on to another tub.

The chassis are identical but the aero configuration for road coarse and superspeedway is quite different, as is the suspension setup

https://www.indycar.com/Fan-Info/IND...-Configuration

Also with the superspeedway configuration, there are two slots, at the front of the floor, either side of the chassis, which are there to prevent the car getting a airborne.

I'm not clear on all the differences either. Surely the tub is the same. Must be some things other than the obvious aero stuff that are different. There was a reference in the NBC coverage that there are even different uprights for the speedway cars. Surprising to me as even in the CART era when the rules were much more open, we ran the same uprights for all events. Wonder if Dallara has a website with a parts list.

I'd be surprised if Carlin had a spare oval car for Alonso but not for themselves.

Hinchcliffe on the other hand has an oval car to try and qualify.


At least, that's how I understood it ?

The McLaren/Carlin car was surely prepared with all the speedway bits, whatever they amount to.

How many of the cars that hit the wall looked like they were going upside down but didn't? I don't understand how those slots work but they sure seemed to be effective this week. In Hinchcliffe's crash it looked like the right rear hit the pavement first when he was airborne and rotateded the car to land right side up. A couple of the other cars seemed to right themselves by magic.

Good pole by Pagenued. Of course pole is never a guarantee of success at Indy, but he has a good chance. He's a talented driver.

The slots have blockers in them when not needed, it is a common part to the car no matter the configuration. Look at close-ups of the road course cars and you can see the panels. The remaining parts, according to multiple teams, are bolt on parts. The MAIN difference is the level of massaging that speedway (oval) cars get over road course. Just the bearings are supposedly worth 1 mph, when you're dealing in cars getting bumped by .019 mph even a tenth is huge.

It was fitted with the commonly available bits. Every team has their own tricks with the cars, think ECR just only hires guys at the front end of speedway qualifying? It's not like everyone was banging on Piggot's door for ovals, he was the road course guy, not to diminish his ability in anyway. But teams know how to build for Indy, they take all year to do so. McLaren just under-estimated what it takes because the previous car had Andretti bits already on it. Plus instead of bolting on the damper package Sunday morning and hoping, they had been running it every time out. The car was not a kit they built up themselves(well with Carlin's help but you see where their cars were so maybe not so much help), it was a fully prepped race winning package already.

They seem to have worked, in that a couple of cars that got airborne didn't stay that way and came down safely. if that was the design intention then I salute the aerodynamicist that came up with that.
