Although a popular notion of the NASCAR Series (now Winston Cup, next Nextel)
is that it is a group of good ol boys who have about one degree of separation
from the folks who used to drive moonshine through the hollows at speeds that
would have the Revenuers eatin dust. Technically, that folksiness is far
from the reality of this enormously successful motorsports series. At least
thats the case at Evernham Motorsports. Headquartered in Statesville,
North Carolina, some 50 miles north of Charlotte, which is what seems to be
to stock car builders what Indianapolis is to open-wheel teams, Evernham Motorsports
sits across the road from an airstrip that, given the surrounding area, might
be confused for a pasture. The surroundings are unquestionably bucolic. But
inside the 121,000-ft2 facility, the level of activity and the amount of technology
makes it seem as though its not a NASCAR shop, but something even more
exotic, like an aerospace firm. The hustle and bustlepeople working on
computer terminals that are networked to Evernham Engines in Concord, NC, people
wielding MIG welding torches on exotic-looking tubular structuresare seemingly
unceasing.
But in motorsports, time is key. If you dont show up at the track with
competitive cars (Evernham Motorsports campaigns Bill Elliott and Jeremy Mayfield
in Dodge Intrepids numbers 9 and 19, respectively) each weekend, then you dont
really matter. The clock drives forward, inexorably. There are 39 NASCAR events.
There are various types of venues: super speedways, long and short ovals, road
courses. Cars must be prepped for each. Developments have to be made on an on-going
basis in order to work toward a competitive advantage. Apparently, if they get
time off for Christmas, it is a good thing.
Dr. Eric Warren is not the person that I would have imagined meeting at Evernham
Motorsports, where he is the technical director. For one thing, that Ph.D. It
is in computational fluid dynamics (CFD). Outside of a university, an OEM research
center, an aerospace firm, or an engineering software company, youre unlikely
to run into someone with a Ph.D in CFD. There is another place. NASA. Warren
used to work there before he became involved with NASCAR.

Theyre fast in the pits when it comes to servicing the cars (here its
Jeremy Mayfields Dodge Intrepid); the people at Evernham Motor-sports are
also exceedingly fast back at the shop, where vehicles are being designed, tested
(virtuallythey use wind tunnels at both Swift Engineering and at DaimlerChrysler
and actual tracks when they have the opportunity), and built.

Apparently, Evernham Motorsports is not wholly unlike other NASCAR teams. The
level of technology that is becoming increasingly pervasive in the sport is,
indeed, rising. Warren admits that compared with, say, Formula One, they are
way behind. But gaining.
One way Evernham Motorsports is different is the way that it came into existence.
Ray Evernham, who had been Jeff Gordons manager (the duo put together
47 NASCAR wins and won three championships), was asked in October 1999 to bring
the Dodge division back into NASCAR after 20 years out of the series. Which
was certainly a big opportunity. But there was also something of a caveat attached:
the task was to be completed in 500 days. Ready to race. And no extensions to
the deadline. None. What this meant was a new team. A new company. A new engine.
A new car. And a deadline tighter than a gnats anatomy. Evernham is a
charismatic leader who has even been featured in as non-racing a magazine as
Fast Company (its name sounds quick, but it is a business publication, if youre
not familiar with it). He has what he calls 20 Points for Success.
They include:
2. Hard Work. That sounds cliché...but it takes hard work to be successful...Life
is not easy...Its not supposed to be.
3. Doing What Ever It Took. Do whatever it takes...any job that must be done...any
position that must be filled to complete the mission is your responsibility...Find
A Way.
4. Being Surrounded by Good People. Over achievers...Learn to identify
good people...Figure out how to get them on your team...Learn what motivates
them and provide that motivation.
Which he presumably called upon to be ready for the first race: the prestigious
Daytona 500. On February 18, 2001, Evernham Motorsports driver Bill Elliott
started the race in a Dodge Intrepidfrom the pole position. What might
have seemed impossible to many was probably just difficult for the Evernham
Motorsports team.
Evernham Motorsports was not the only team to have Intrepids during the 01
season. Bill Davis Racing, Petty Enterprises, Melling Racing, and Chip Ganassi
Racing with Felix Sabates also had the cars. But Dodge, which took what was
described as a one-team approach, designated Evernham Motorsports
to serve as a team coordinator for the development activities with relation
to Dodge. In fact, when I visit, there is a group of people who actually work
for other teams who were being briefed on a 3D scanner, the Capture 3D ATOS,
from a German company (Gesellschaft für Optische Meßtechnik), which
will be used to scan entire bodies, from bumper-to-bumper, with an accuracy
of 0.003 in. Theyre inside the Evernham shop. Of course, whatevers
proprietary is kept out of their view.
The invitation to visit Statesville came from IBM. Having had the opportunity
to visit the shops of teams from other series, I had expected that the Evernham
shop would be much the same. Some small pockets of technology that are interesting,
but not particularly astonishing. But in point of fact, the team is doing some
things that companies much larger ought to model themselves after.
Like many NASCAR teams, Evernham gets a chassis from Ronnie Hopkins. We
spend approximately 110 man-hours on each chassis that we get in, Warren
says. Given that there are two carsElliotts #9 and Jeremy Mayfields
#19this means that theyre spending a lot of time doing the modifications.
So theyve decided that theyre going to apply technology to design
and build their own chassis. This is not a case of throwing the proverbial switch.
Theyre not dropping the sourced chassis immediately and going with their
own. Rather, they are working slowly and methodically. Other teams are
building their own chassis, Warren admits. They started with an
existing car and built fixtures to it. While there are an abundance of
fixtures on the shop floor at Evernham, theyre taking a different approach.
We started from scratch. Were designing it with CATIA, and are doing
the proper FEA analysis. Were even taking a new approach to building it.
We took a look at the pilot plant operations at Auburn Hills and how they do
fixturing, and we got ideas from them. The main idea is that all of the
fixturing information is also designed in CAD. The consequence is that theyll
have spatial relationships between all of the piecesfrom the tubular frame
parts (they outsource the bending, which is being done on CNC equipment so that
there is, Warren explains, no need for manual bending, coping, or hand fitting:
It comes in the door, and we start welding) to, eventually, the
body panels (presently, with the exception of the hood, roof, and decklid, which
are stamped for the team by Dodge, all of that sheet metal you see is hand-formed,
mainly of 24-gauge sheet steel; the nose and tail are Kevlar). Everything will
fit. This design work is being done with CATIA V5, which theyve transitioned
to from V4. Which puts the team at the forefront of the latest CAD technology.
(They started the car design in V4 but are moving it over the V5.) Before the
2003 season is over, there is full intent to have an Evernham Motorsports Intrepid
racing car.

Bill Elliott put his number 9 on the pole at the 2001 Daytona 500, which is all the more remarkable when you take into account that it was a new car, new engine, new team, and Dodges return to NASCAR after 20 years.

Initially, it will take them longer than the 110 man-hours. It will be 240
man-hours at first. Then theyll get faster. And faster. Because theyll
have the data.
Each team has 14 cars. Although a NASCAR vehicle is comparatively Spartan vis-à-vis
your dealer-sourced Intrepid, there are still plenty of parts to contend with.
So in order to keep track of the parts, they have developed an in-house system,
the Parts History Maintenance Log (PHML), which is based on a SQL database.
At any moment, Warren says, we know where parts are, what
cars they are on. After a race, all of the mileage for each of the parts
is entered into the database, so they not only know what parts they have, but
how many more miles a given part is good for before it is retired from active
use or otherwise handled.
Whats more, this capability is particularly good for vehicle setups:
If one of the teams two vehicles is doing well during qualifying, they
know precisely whats on that car. Say the steering is really good: they
can see, for example, what control arm is being used. Then, if they have another
just like it (which, of course, theyll know because of the real-time inventory
capability), they can put it on the second car.
They are looking at integrating their PHML system with their SMARTEAM product
lifecycle management system (like CATIA, a Dassault Systemes development); Warren
says they are also going to be linking their CATIA system to SMARTEAM, as well.
It was managing the development and change processes that led us to SMARTEAM,
he notes. There are also plans to integrate CATIA and SMARTEAM, as well, thereby
facilitating better control over the vehicles and the elements that are used
to produce them.
The implementation of these systems is fast and deliberate.
A year from now, well have our own fairly large-scale Linux cluster
doing our in-house computations, Warren says. They are testing the use
of tablet PCs for use at the track so that theyll be able to (1) communicate
from garage to garage (it may be that Elliotts pit position is at one
end of the lane and Mayfields at the other) and (2) communicate back to
the race shoponce theyve established a network that will provide
this capability. Warren looks forward to installing CFD software, Cobalt, that
has evolved out of Wright-Patterson Air Force Base. The level of technology
that theyre working with at Evernham Motorsports is nothing if not state-of-the-art.
Why are they doing this? Warren has a good explanation: People at some
other teams will go fast, but they wont know why. We go through periods
when we cant figure out what it is that were doing to perform the
way we are. But the more time we spend knowing what the products are, doing
the analysis properly, taking an engineering approach, the more well understand
why were quicker.
And the more they understand why theyre quicker, the quicker theyll
become.
