Andretti Signs Wilson

Andretti Autosport announced Friday morning the signing of IndyCar veteran Justin Wilson to the team's lineup in May's Grand Prix of Indianapolis and Indianapolis 500.

With 7 wins, 26 podiums and 8 poles over his 11 year Verizon IndyCar Series career, Wilson joins Andretti Autosport on a partial-season basis in the No. 25 car after multiple full-time deals for the 2015 season fell through with the team. Simona De Silvestro, who is competing for the team this weekend in St. Petersburg in the No. 25, is also running a partial-season with the defending Indianapolis 500 Champions. The Swiss driver, at this point, is only confirmed for the season opener.

Andretti Autosport is working with both Wilson and De Silvestro as well as other drivers to run their 4th entry full-time and a possible 5th entry part-time.

Steak 'n Shake To Sponsor Rahal

Rahal Letterman Lanigan Racing announced Tuesday the signing of Steak 'n Shake to the team's 2015 sponsor lineup. The restaurant, who are making their first foray into Indy Car, will be the primary sponsor on the No. 15 entry of Graham Rahal at Long Beach, the Grand Prix of Indianapolis, Indianapolis 500, Detroit and Mid-Ohio. The Indianapolis based company will also be an associate sponsor for the 11other events.

“I’ve been eating them since I was 11. Finally, free Steakburgers!” said team co-owner David Letterman.

Maxim Magazine will also be featured on Rahal's entry. The magazine is owned by Biglari Holdings Inc., also the parent company of Steak 'n Shake.

The team announced earlier this month D-A Lubricant as primary sponsor in New Orleans. The company, who sponsored cars at Indianapolis in the 1950's, also signed a multi-year agreement as a major associate on the team's primary entry.

Honda Aero Kit Unveiled

Honda Performance Development released Monday night images of their 2015 Verizon IndyCar Series aero kit.

Consisting of nearly 200 individual pieces, the kit was validated using Driver-In-Loop Simulators before full-scale wind tunnel and on-track testing. In total, Andretti Autosport performed six tests on various road courses and short ovals.

For comparison sake, Chevy vs. Honda:

2015 '500' Ticket Unveiled

The 2015 Indianapolis 500 ticket was unveiled Thursday in downtown Indianapolis.

Featuring Ryan Hunter-Reay chugging milk in Victory Lane, the long-held tradition of the defending champion's likeness highlighting the following year's ticket continues.

Hunter-Reay was unable to attend the presentation, but for good reason. He and wife Becky had just welcomed their 2nd child into the world.

"I think we have a good excuse here (to miss the unveil). I’m sure you’ll be seeing him at the racetrack, we already have his DHL firesuit on order."

Tickets for the Angie's List Grand Prix of Indianapolis and 99th Running of the Indianapolis 500 are on sale now.

Chevrolet Unveils Aero Kit

Chevrolet unveiled their long-awaited 2015 road and street course aero package at the Indianapolis Motor Speedway today during INDYCAR's Media Day.

Chevrolet's Director of Facing, Mark Kent, was first to speak:
"It's a pleasure to be with you to highlight some of the key steps of where this aero kit is today. It's been a long journey. We're glad to be where we are.  
The first step that we took along the process was doing some baselining of today's car to fully understand what the DW12 does on road courses and short ovals to ensure our kit performed to a level that exceeded today's car.  
Once we understood where we were starting, we developed numerous design concepts. This is probably the biggest challenge, to balance the requirements for the kit. It's not all about downforce, it's not all about drag, it's not all about engine power. It's developing that optimal combination between those three to ensure at the end of the day we are providing our Chevrolet teams an aero kit and engine combination that can let them win week in and week out.  
Once we established these goals, we had some design concepts, some renderings that we had on what we thought the car could look like. We had a very focused, dedicated team that worked on this aero kit program that then took these renderings and put them into the computer through computer-aided design, which we then took one step further and did structural analysis of the components.  
The new Chevrolet aero kit has more downforce capability. So in addition to ensuring that parts are light, we need to ensure they can withstand the higher loading. The FEA analysis with key that our parts would perform in that environment.  
We then took those parts to the next step, which was to use the computer to simulate the aerodynamic properties. A lot of our up front work was done on the computer. It's a very efficient and effective way in order to run through numerous designs before you even start to produce parts.  
So once we ran through this process, and I'm going through these in linear steps, but this is obviously a cycle. We go back a lot and start over based on learning along the way. Once we got to this point, the next step was then to create rapid prototype parts. Today's technology is amazing. You can take a 3-D printer and produce parts like this that is carbon-filled parts that are strong enough to actually go on a racecar and be tested on speedways and ovals and road courses. It's an amazing technology that allows us to rapidly learn what our parts do and rapidly allows us to go back and make enhancements as required.  
Once we had the parts, our next step was to go to a scale model wind tunnel, 50% scale model of the car. 50% testing offers us a great opportunity to learn quickly and more efficiently, producing parts that are half the size of the real parts represent a cost savings and allows us to test numerous iterations more rapidly.  
Once we were satisfied with those results, the next step was to go to a full scale wind tunnel test. We produced rapid prototype parts, took them to a full scale rolling wind tunnel, conducted numerous tests to confirm what we learned in the scale model tunnel and the computer.  
From that point we moved on to testing a prototype aero kit on various circuits. We tested the kit on various tracks. 

Chevrolet's IndyCar Program Manager, Chris Berube, was then brought into the conversation:
The validation phase of this whole thing was the track testing phase. Our goals there were really about making sure we had correlation all the way back to the CFD, the beginning of the process that Mark talked about. It's very iterative. We went through it here in a single pass. But this is a very iterative process. 
So once we got to the point where we produced full-sized prototype parts, we tested this road course and short oval components on real cars on Homestead, at CoTA and Phoenix for a short oval.  
We were glad to have Helio and Juan Pablo help us at Homestead. At COTA we had Will and Simon in the car. Then at Phoenix we had Scott and Tony running for us. Got a number of team Chevy drivers through this that helped us keep making progress in the validation phase, which is what the track testing is all about.  
Let me take you through some details of the kit. I'll give you some close-up shots and help you out with the terminology.  
We have a brand-new endplate, unique technology design there. The front flap adjustor will be very visibly different than the DW12.  
The front upper very prominent feature in the new front wing design. Inboard fence again, another new part, that ties it together. Seven parts in our new front wing assembly compared to four on the Dallara side.  
Moving on, we look at the center of the car, towards the rear we have a wheel wedge in front of the rear wheel, compared to the Dallara where the side pod carried all the way over to the front of the rear tire. We have a new side floor kick that you'll see behind the pod wing. A new part on the side pod that we call the upper flick. Our side pod and side pod inlet are also new.  
Moving over to the engine cover now, we did maintain the overhead intake as is in the DW12, but you'll see a much more shrink-wrapped tight engine cover without that vent in the back. It is quite a bit of a tighter package in there.  
To the back of the car, we have new bumper pods. We'll use this as all events. There's another part on top of it we call the top flick, which will not be there at all events. It will be an optional part.  
New end plates with louvered features in them. Our upper rear wing development is a dual flap design as opposed to the single flap that the DW12 has.
The Chevrolet oval package will be revealed on a later date. Honda has not released a timeline on the release of their aero kits.
