IndyCar Aerodynamic Body Kits Revealed Side-By-Side (kinda')

The evening of Monday, March 10, 2015 saw the final reveal of the aerodynamics body panels (Front Wing, Sidepods, Rear Wing) for the beginning of the third season of the Dallara DW12 chassis.

Chevrolet introduced its road course/street course and short oval design Feb. 17. The much-anticipated unveiling of the Honda aero kit took place Monday evening at a reception attended by principals from Honda Performance Development, American Honda and IndyCar. Defending Indianapolis 500 winner Ryan Hunter-Reay, who drove for a bulk of the on-track development, joined Honda executives in showcasing the base road/street course and short oval aero kit.

Possibly the most accomplished pilot using a Honda engine for 2015 Verizon IndyCar Season, 2014 Indy 500 winner and 2012 IndyCar Champion (using Chevy-power) Ryan Hunter-Reay, had the aerodynamics body work applied to his Andretti Autosport DHL Dallara DW12 for the Honda Performance Development reveal.

Chevrolet and Honda, the current engine suppliers to the Verizon IndyCar Series (America's top professional open wheel chassis motorsports racing series), under the rules laid out for 2015 are able to modify the original body work of the Dallara DW12 to enhance the racing platform as it relates to airflow and give, potentially, an additional advantage to the teams that use their engines. The previous two years that the Dallara DW12 was on the track, all body parts were exactly the same as manufactured by Dallara from the factory for all teams (Honda or Chevy).

The reveal timing all seems a little delayed in relation to generally understood timing used to build fan interest. One wonders how fans, who support the series, are able to analyze and absorb the subtle aero approaches each manufacturer has adopted given that the Firestone Grand Prix of St. Petersburg, will be run in just about 3 weeks, on March 29, which marks the inaugural 2015 competition between the manufacturers' body kits. The speedway aero kit components are scheduled to be delivered to teams by April 1.

Below are full chassis images originally supplied by IndyCar from the manufacturers. The larger hi-res images were cropped in order to bring a visual focus to the three main areas of where aerodynamic body panel manipulation takes place on the Dallara DW12 - the Front Wing, Sidepods, and Rear Wing body parts - for comparison.

First, Chevy supplied the initial image that shows the fluid dynamics effect of their developed approach. The way the lines are drawn, it leads one to believe that the turbulent airflow coming from the back of the chassis has a strong upward motion soon after leaving the rear wing of the chassis.

This fluid dynamics motion is called 'Mushroom Busting' (first coined by Swift Engineering during the Iconic Development Process) which moves the trailing turbulence, that forms in the shape of a mushroom cap, out of the way of the race car behind allowing for stability in racing and possible overtaking.

Frontview Detail Comparison

This close-up view comparison has one potentially questioning whether Honda wishes to continue the same 'Mushroom Busting' competitive agenda, explored and - EXPLAINED HERE.

The Chevy front end view seems to have less parts to get in the way of the fluid nature of air whereas the Honda front end has many more elements that appear to be aiding in the dropping of the turbulence mushroom so that it would act as an impediment to any car trailing the Honda-powered chassis.

Front Wing Detail Comparison

This close-up view comparison has one potentially questioning whither Honda wishes to continue the same 'Mushroom Busting' competitive agenda - EXPLAINED HERE.

The Chevy front end & front wing views both seem to have less parts to get in the way of the fluid nature of air whereas the Honda front end clearly has more elements channeling and funneling the air.

Sidepod Detail Comparison

Chevy Sidepod Detail - Image Credit: IndyCar

Honda Sidepod Detail - Image Credit: IndyCar

The sidepods housed the radiators in the original version of the DW12 so it is assumed the same function of the airflow through the housing performs the same benefit of cooling the engine.

Again, the Chevy sidepod has fewer elements and an addition of an airflow pass through outport just in front of the rear tire. Chevy also supplied a component identification terminology plate which describes the flying wing on top of the sidepod as an 'upper flick' and the element in the middle of the back of the sidepod (main flick) as a 'wheel wedge' which looks a little like a shark fin placed on the pod.

No component identification terminology plate was available from Honda/IndyCar so one is left to guess. The most interesting characteristic seems to be the integral nature of the sidepod without many add-ons or outports carving up the side, visually, and hanging above, leaving an uncluttered profile.

Rear Wing Detail Comparison

Chevy Rear Wing Detail - Image Credit: IndyCar

Honda Rear Wing Detail - Image Credit: IndyCar

For the Chevy rear wing, we almost instantly see louvers on either side of the main central fences or end plates. The louvers allow air flow to move from the central wing section defined by the fences over to the airflow on either side of the central wing.

The Honda aero kit features an added fin along the backbone of the engine cover along with, again, more parts that appear to most observers to aid in the dropping the strength of the upward movement of the turbulent air mushroom cap ... but then, who really knows without the developmental CAD/CAM information and testing statistics. One might say that the Honda aero kit looks less than ... iconic. More parts placed at the corners of the racing platform also equal more Yellow Flag track litter.

As an example that aids understanding in the philosophy that less parts that impede the flow of air is better, the new Nissan GT-R LM NISMO LMP1 employs the use of very large, designed-in airflow ducts where nothing invades the space of the duct.

This excerpted and edited from Racer -

Inside the Nissan GT-R LM NISMO LMP1 program
By Marshall Pruett - Feb. 1, 2015

Designers spend thousands of hours coming up with the best way to make aerodynamic downforce while minimizing drag, and drag comes from interrupting the air.

An LMP1-H punching through the air at 200mph is one giant exercise in disturbance, yet with Bowlby’s through-flow system, he’s found a brilliant method to work peacefully with the air as it envelops the Nissan via huge rectangular airflow channels that start at the rear of the splitter, wrap around the cockpit, and continue to the tail end of the GT-R LM NISMO LMP1. In practical terms, it’s the difference between the hull of an oil tanker making a huge wake and the razor-thin interruption made by an America’s Cup yacht.
[Reference Here]

One thing for sure, only racing on the track will let fan, team, and driver alike really know for sure.

If one hears about difficulty in passing a Team Honda car over the ease at passing a Team Chevy car just know that you heard the first speculation written about >>> HERE!

Book Review: Think Fast - The Racer's Why-To Guide to Winning

Book Review: Think Fast - The Racer's Why-To Guide to Winning

Think Fast - The Racer's Why-To Guide to Winning, was written by one of the forces behind the successes at Swift Engineering, Neil Roberts.  Think Fast was first published by the author in 2010, with the most recent edition published June 5, 2012 which can be purchased directly from the author (ISBN 1451558759; MSRP $30; http://thinkfastbook.com/).

Think Fast is a collection of Neil Roberts' insights, as a winning SCCA open wheel racer, professional race team engineer (CART) and aerospace engineer. Roberts explores decision-making and time management issues involved with creating and managing a winning racing effort.

The author addresses four major topical areas in this book -- driving skills, the mental game, automobile tuning, and engineering.  Chapters include helpful illustrations and graphs that communicate very effectively.

Included are tips on autocross & track driving, race car set-ups, engineering dos & don'ts, and race team management; however,  this "why-to" softcover could be an inspirational how-to guide for any process-oriented business effort or an individual exploring promising routes to a directed, successful life.

Sections of Think Fast may appear to target engineering-minded race car developers who expect to drive, but they are finessed to allow the non-technical reader to easily understand the dynamic forces involved with each of the automobile subsystems discussed.

I was enlightened by the author's concepts on becoming a winning thinker, person, team member, and controller of one's own destiny.  Neil Roberts effectively communicated nuggets of information he gleaned over a multi-faceted career in competition combined with humor and personal situational anecdotes.

Some of the more compelling and/or enjoyable concepts covered in Think Fast are:

-- "If you are looking for an employee who will get the job done on time every time, who will take full responsibility and pride in the results that he or she produces, and who considers exceeding your expectations to be standard practice, HIRE A RACER."

-- Under Right Of Way - "The car in front of you owns the entire width of the track , even if you are along side, and even if you are about to lap that car. The car in front of you has the right to use any and all of the track, the curbs, and the grass, so any contact is your fault. The instant that the nose of your car edges ahead of the nose of the other car by one micron, the roles reverse. Now you own the entire width of the track, and you can drive anywhere you want."

-- "If your car starts to feel like a faithful servant, you are not driving it hard enough."

-- "There is an easy way to tell whether or not a race car part is too heavy. I you let go of it and it falls down, it's too heavy."

-- "It is just as easy to calculate laps per pound as it is miles per gallon."

-- "The voice of reason has a very hard time competing with the volume of nonsense in the paddock."

-- "Never carry anything around in your head that you can carry around in your trunk."

-- "Despite the title of this book, "Think Slowly" is much better advise when it comes to making handling changes. It takes some effort to take the time to stop, sit down, close your eyes, and think it [the problem] through carefully before you make any race car development decisions."

--  “It takes some effort to separate your ego from the value that your idea offers. People should be treated with respect. Ideas should be beaten to within an inch of their lives. The good ones survive by demonstrating real added value to the program."

-- "Everyone reports to someone, and the boss reports to the customers. If the boss forgets that, disaster is guaranteed."

-- "Given the colossal effort that is required to finish first, it should be completely obvious that victory is earned, not won. Victory is the goal that we all strive for, but it's only one result of many other things that must be earned on the way there."

Neil Roberts knows how to communicate ideas through the written word. If this were just another book written by an engineer, for engineers, watching paint dry might be a better choice of pursuit than Roberts' Think Fast -The Racer's Why-To Guide To Winning. This book is recommended reading for anyone focused on improving their understanding of making cars fast, and on a much larger level, honing one's process-oriented thinking for other, more important tasks encountered through a life lived well.

96th #INDY500 Tweet-By-Tweet - A Live Blog Effort

This edition of the "Greatest Spectacle In Racing" will be unique due to one major overriding issue, the new Dallara DW12 is racing in its first oval race and it happens to be the biggest, most historic venue one could choose for this maiden outing.

Fans and drivers are excited to see how this platform will perform in traffic because these cars are much kinder to the cars that trail behind them due to the aerodynamic effect known as Mushroom Busting incorporated into the design of the body work. What this means is that the disturbed airflow behind the car has been directed above the racing surface much more quickly than previous designs and this allows a car riding behind another car to be more stable and be able to get a "TOW" from the car in front.

Multiple car teams like Andretti Autosport with five cars entered may have an advantage if the team drivers work together as roller-derby teammates would work together to "sling-shot" each of their drivers forward.

The additional subtext to this 500 mile race would be the durability of the new racing engine formula. Three engine manufacturers have been authorized to produce these engines and it would seem that the weakest link resides with the DW12's powered by the Lotus/Judd turbo-charged engines. How many laps will they go before they are 1) Black-Flagged for being too slow or 2) if they will be able to complete the 500 miles still running without a failure.

Of course the final outcome will be watched by the Chevrolet and Honda engine team for their own ability to be able to complete the 500 miles still running without a failure as well.

Predictions are that either KVRT's Tony Kanaan or defending championship team of Bryan Herta Autosport's #98 Alex Tagliani would be the winner at the end of 500 miles. If the race is won by a multiple car team that would go to Andretti Autosport with Ryan Hunter-Raey. Fastest female now that Danica Patrick isn't sucking the PR air out of the room goes to Andretti Autosport's Ana Beatrix. Top former F1 driver goes to KVRT's Takuma Sato. Highest placing former INDY500 champion would be Helio Castroneves - Motorsports Unplugged Radio.

Final top ten - Dario Franchitti (from P33 to P3 on one stint), Scott Dixon, Tony Kanaan, Oriol Servia (former Lotus-driver), Ryan Briscoe, James Hinchcliffe, Justin Wilson, Charlie Kimball, Toensend Bell, and Helio Castroneves

This is the first race of the season not won by a Penske Racing driver, but it still is a race win by either a Penske Racing or a Chip Ganassi Racing driver!

Ashley Judd Franchitti is absolutely beside herself as well she should be - Dario Franchitti becomes a Three-Time INDY500 Winner - dedicates the race to Dan Wheldon in post race interview (paraphrased).

"To be placed on the trophy besides Dan means the world to me."

Dario gets an Igloo cooler full of icy water dumped on him ala winning Football Coach/Super Bowl style.

 Post race interview has Takuma Sato complaining that he had taken the position but Dario pinched him down so hard that it caused him to have to be below the whiteline causing his DW12 to spin and hit the wall. 

The 96th Indianapolis 500 is in the books and should be renamed the "Mushroom Buster 500" in honor of the technology that brought together a great, competitive, and record 35 lead change race.

Dallara DW12 Speedway Aero Takes A Nod From Swift Engineering

Dallara DW12 Speedway Aero Takes A Nod From Swift Engineering

The major difference with the 96th running of the Indianapolis 500 ... the Greatest Spectacle in Racing ... and virtually all previous editions of the race is the racing platform technology.

Most people who have been following American open wheel racing since the beginning know the trials and tribulations with the separation and unification of the series but few really have a handle on as to why this year will be different than any other year.

The IZOD IndyCar Series has adopted a new chassis that handles the flow of air much differently than chassis of previous years and this change lays mainly in the concept of managing the airflow vortex that is created by the car and what happens to the flow of air after it leaves the back end or rear wing of the open wheel chassis. The car punches a change of the nature of the air ... or hole in the air and this allows a car that is following to pass through the same space more easily, with less drag. Some have come to term this effect as "Tow" but what is really happening is that the new design manages the flow of the air to allow for the vortex "mushroom" to be busted. An aerodynamic design feature first pioneered by Swift Engineering and put into play by some very enterprising aerodynamic engineers at Dallara for the Speedway Configuration of the DW12 chassis.

Bryan Herta Autosport's Alex Tagliani had the following observation as to this "Mushroom Busting" effect upon the trailing car, a car following a lead driver:

“You can really see it. If you make the corners flat (out), and being within three car-lengths, you'll get sucked in,” explains Alex Tagliani, who's understandably bullish about his chances having both a Honda and running with defending champion team Bryan Herta Autosport. “If your car isn't as good, and you're maybe four lengths back, you'll still be able to suck in three, but you'll just getting right on their back.”

This is where the timing element comes into play. “Getting closer, you get more disturbed, and if you lift, you become a sitting duck,” he says. “The timing of the draft is very important, but you also have to stay within the appropriate distance to pick up the tow and get by the guy.”

Surprise Swift Tour Yields A Look At "Concept 66" Platform
(originally posted 4/16/10 - 1:28 PM)

If the folks at the IZOD IndyCar Series are thinking with a level head, given what we, at The EDJE, were exposed to at a surprise tour of the Swift Engineering facility in San Clemente, they will soon be singing "We get our kicks settling on Concept 66" as their way of the future of open-wheel racing.

We were invited by the Publisher of The Motorsports Report, Dicken Wear, as an impromptu field trip after checking in at the Toyota Grand Prix of Long Beach Credentials area to pick up our Photo Vests for this weekends event. What a bonus since the major motorsports events of the day would be background shots taken while the IRL, ALMS, World Cup Challenge, and Firestone IndyPro Series cars practiced so the teams could dial in for the races ahead.

A group of about 20 people (writers, drivers, engineers, and photographers) gathered and were treated to a tour of the facilities at Swift that included a look and demonstration of their on-premises 140 mph wind tunnel, driving simulator, and composite fabrication areas. We were led on the tour by Program Director, Casper Van Der Schoot originally from Holland by way of Hogan Racing.

Casper enlightened the eager crowd with the concept of designing to reduce the effects of the vortex "dirty air" so that the platforms could race nose to tail with greater safety and, of course, greater competitiveness. The design concept of how to do this came in the development of a rear wing and forward rear wheel pod shapes that turn the Concept 66 into a "Mushroom Buster"!

One can not totally eliminate the shroom effect, but by shrinking the width of the shroom plume, and raising the "cap" of the shroom so that it is moved away from the following platform ... the mushroom is effectively busted.

UPDATE: Swift Concept #70 proposal for the next IZOD IndyCar

The IZOD IndyCar ICONIC Committee earlier this week, received a presentation previewing Swift's concept #70. The #70 is the latest evolution open-wheel car concept and incorporates aspects of the six previously launched concepts Swift has designed over the past nine months.

“Our latest concept evolves elements from our previous concepts and from the direct feedback we have received from the series, teams and fans,” said Casper van der Schoot, Swift's Program Director in an interview published in Racer Magazine. “I would like to thank the fans who have provided great feedback to us through our Facebook page and in particular Erik Berkman and Dave Marek from Honda for sharing with us their data and modeling for their next generation V6 powerplant as well as their chassis styling concept that weighed heavily in our design.”

The main thing that Swift was able to design in and keep in the #70 was a nose-to-tail racing safety and competition design concept known as "The Mushroom Buster" explained in the breakthrough design first introduced with Design Concept #66 above.

"The 70 has increased signage real estate, as demanded by the teams,” said Mark Page, Swift's Chief Scientist to Racer Magazine. “We enlarged the car's bodywork and angled the surfaces so that they present the best view to the fans. We also have a new 'Mushroom Buster; design. This promotes passing by busting the 'mushroom cloud' of dead air behind the racecar. Our number 70 model was run through extensive Computational Fluid Dynamics on our new Cray supercomputers. The Cray has increased our capability 50-fold, and we now know our car will have significantly less drag than the current car.”

“The monocoque is larger than the current spec,” stated Chris Norris, Swift's chief designer in the same Racer interview. “It is designed to accommodate driver size from Danica [Patrick] to Justin [Wilson] with added padding beneath and behind the driver. In addition we have added anti-wheel lock blades dubbed, ‘Satan's teeth' aft of the front wheels, attached to the front of the sidepods. Also an anti-lift approach to the design of the front wings and sidepods will dramatically reduce the likelihood of the car getting airborne.”

The IZOD IndyCar Series is reviewing the Swift and four other manufacturer's value propositions and is expected to make its decision for the next generation IndyCar for 2012 by June 30, 2010.

Well, Dallara won the contract and the incorporation of the mushroom busting design in the DW12 is very evident, more so than with a road/street course aerodynamic set up. Maybe as this author had done with the quote used by Alex Tagliani for this article, Dallara should place at the bottom of each rear wing assembly [ht: Swift Engineering] ... do ya' think?

This year, the "tow" will be the story of the 96th INDY500 race and it will be because of moving the dirty air vortex up and away from the track surface - Mushroom Busting - which will allow cars to be more stable and gain an advantage on the track if used properly.

IZOD ICONIC Decision For 2012: From Hot Cars ... To Haute Cars

The decision for the future platform and competition in the IRL starting in 2012 was a PUNT. Nothing new here than the Ol' Boys Club sticking together without disturbing the apple cart that has been around 2002 on the manufacturer side.

From IndyCar PR --

WHAT THEY’RE SAYING ABOUT 2012 IZOD INDYCAR SERIES CAR STRATEGY

INDIANAPOLIS (July 14, 2010) – Quotes from selected IZOD IndyCar Series drivers, team owners, manufacturer representatives and other officials about the 2012 car strategy unveiled by the IZOD IndyCar Series (in alphabetical order):

“The ICONIC group has come up with a smart way of bringing diversity and a new look to the 2012 IndyCar while keeping longtime partner Dallara, who has the expertise and an incredible amount of knowledge of the technical specifications of the IZOD IndyCar Series. Obviously as a team owner, I will have a lot of questions regarding this new concept, and I want to be reassured that the new rules around this car will guarantee a good operating cost control and a good open competition in between teams. It is also good to see that the state of Indiana is behind the project.”
-- Eric Bachelart, Owner, Conquest Racing, IZOD IndyCar Series

“Everyone at IZOD is very excited about today’s announcement because the chassis decision encompasses all of the characteristics that attracted us to the IndyCar Series as a title sponsor. The design represents innovation, speed, technology and performance, all of which are attributes of the IZOD brand. The new car, with the extra 100-horsepower push-to-pass capability, will create even greater moments of speed and competition, which is unbelievable. And the fact that they were able to accomplish all of this while keeping the costs contained and the drivers safe is a real tribute to the ICONIC committee and their forward thinking. We think this will bring the sport to whole new level of competition.”
-- Mike Kelly, Executive Vice President, Marketing, Phillips-Van Heusen, parent company of IZOD brand

“This is a great day for all of us in the IZOD IndyCar Series. I couldn't think of a better manufacturer than Dallara to make the Safety Cell, and, of course, make that product in Indiana. Add to that the fact that there will be development around that cell is fantastic. It's what fans and competitors alike have been wanting, and in 2012, we will have exactly that but at a much lower cost than what we are running now. In most aspects of life and business, it costs more to get what you want, but somehow the ICONIC committee has managed to achieve the right product at a substantially lower price. I can't wait for 2012.”
-- Alex Lloyd, Driver, Dale Coyne Racing, IZOD IndyCar Series

“A lighter car is more nimble, makes it easier to pass people. With the turbo engine, you can increase that power to pass a lot, and make for better racing anyway, and more horsepower makes it tougher to drive. There’s more mistakes, more opportunities to pass. You couldn’t have asked for anything better. We have a one-make chassis now, and now we’ll have a common tub, which is safe. And you’re able to design your own bodywork.” (Can you imagine going 240 mph at Indianapolis in a car like that?): “I love competition, I’m not sure that it’s necessary to go 240 again. This year, gee, we were going 228, and it’s getting up there. I think it’s something you have to wait, see and watch it develop and see what horsepower works best where, because with a turbo you can adjust that. The thing I like is it will take its own direction with the design because it’s open.”
-- Will Power, Driver, Team Penske, IZOD IndyCar Series

My favorite quote came from Tony Purnell,, a member of the committee that formulated the new rules, as he summed up the decision in a challenge to those various participants: "So come on, Ford. Come on, GM, Lotus, Ferrari. Come on, Lockheed. Come on, Boeing. Come on, you engineers working in small technology businesses. We want you to rise to the challenge." Yea, right ... General Motors is still a government operation, and the others really would not want to put lipstick on someone else's frame (pig). It would be hard for any of them to develop "skin" in the game.

Basically, the IRL is looking to create a fashion show reality series entitled "Dress This Italian Pig" (I thought this was to be an American open-wheel racing series with the development of drivers and technologies originating on this continent). The only competition will be between Target and Penske being able to continue to sell the other teams ... last year's dress.

Swift Engineering, a California corporation known for its work since 1983 in aerospace, aviation, automotive and motorsports engineering and design, had this "Spec" thing thought out right. Create a car that would be true to the concept of Open-Wheel racing ... unlike the Delta Wing/Lawn Dart ... yet work the aero package to reduce the effects of the after-draft air "mushroom" and allow the cars to run safely, and more closely nose-to-tail. This "Mushroom Buster" concept, first introduced to the IRL in Concept #66 with the final version in concept #70, would increase competition on the track and allow drivers to do what we watch them do ... win through skill.

At least this decision to allow anyone to dress up a Dallara chassis matches up to the sensibilities of the title sponsor ... IZOD, a fashion icon brand. This does not, however, increase the driving competition on the track ... the "Mushroom Buster" concept would never be able to be applied consistently. If I were a driver, I'd want the car following my car to be able to be booted off of the track due to the Mushroom Effect when it was following me at 15 miles per hour (if not 14 mph). In this regard I see the decesion by the IRL ICONIC — Innovative, Competitive, Open-Wheel, New, Industry-Relevant, Cost-Effective — Advisory Committee as promoting chaos when a specification series is what they have ... given the fact there is only one chassis manufacturer

One of the major problems with very small, light automobiles is that they can be unsafe in a collision. The Smart solution is the Tridion steel safety shell. Image Credit: ©1998-2006 DaimlerChrysler via How Stuff Works

This decision feels a little like having a "Smart Car" frame dressed ... in a new skin.

We, at The EDJE have one question (actually two), does the "Lawn Dart" (Delta Wing) closed-wheel design have any of these considerations built in to their design(?), and if the Delta Wing could deliver what Swift Engineering has proposed ... will fans of open-wheel racing ever accept a car that by design definition - isn't even open-wheel?

We are holding our breath ...
