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. “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. “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 Swift's and four other manufacturer's value propositions and is expected to make its decision for the next generation IndyCar for 2012 by June 30.
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 ...
