Next Generation Champ Cars
- An opposing view Robert Kleine
(Germany)
February 21, 2004
I wanted to write my views regarding the Next Generation Champ Car
awhile ago,
but with all the things that went on with the sale of CART I wanted to wait to see if there
would be a Champ Car series in the years to come. Now that it’s clear we won’t lose our
beloved series I want to present my two cents worth.
I don’t want to see the Champ Car Series turn into a cheap F1 clone using these butt ugly
F1 or future F2 chassis with their air boxes and raised noses. F1 isn’t the most popular
sport in the US and I don’t believe Champ Car would become any more popular by adapting the
chassis/engine package of F1 or F2 and selling it to the fans as an American F1 or
whatever. I would probably walk out on CART/OWRS if they chose the “road to conformity”
[Editor's Note: Our articles have repeatedly suggested a lighter and
smaller car on par with F1. Never once did we suggest air boxes or a raised nose.]
I got hooked on CART just because it was different than F1. Being a European myself I
could have gone to a lot of F1 races but I just wasn’t interested. I flew to the US
instead to attend CART races because it was a different kind of open wheel racing. What
in the heck should still keep me interested in CART if they chose the road
AutoRacing1.com is
proposing? [Editor's Note: He missed our point completely.]
The ultimate racing machine
This car above is definitely not my impression of an ultimate racing machine, at least
not for the Champ Cars.
I agree that slight alterations in the design are necessary and some of your ideas are
great in a true sense but I don’t think CART/OWRS should completely give up the key
elements of their heritage.
I have always been saying that I would like to see the series stick with their turbo
engines and their chassis design because that is what makes a Champ Car. I remember a
personal conversation between you and me where you said that it doesn’t matter to the
average Joe how an open wheel racecar looks like. You might be right, but there are
hundreds of thousands of Champ Car fans who do care how their favorite race cars look
like. And these are the people who stuck with CART through thick and thin. So these are
the people who should matter in the first place. Sell the product to the average Joe
later.
Right now I want to come back to your table about a future Champ Car:

I want to give you my opinion on the points
you address:
I think that a future Champ Car should be designed to race on road courses, street
courses and ovals because that diversity of tracks makes the Champ Car Series so
interesting. They should not drop oval races all together.
They should have chassis built by different manufacturers. This creates competition. It might
raise costs, but I never expected that running a ChampCar season would be as cheap as
running an Atlantics season, anyway. Leave the spec chassis to the lower series.
I do agree that the chassis should be slightly smaller in length, width, wheelbase and
therefore lighter but on the basis of the current chassis design including underbody
with tunnels (see images below of the “enhanced” Champ Car chassis in comparison to
the current chassis). Let it stay a ground effects car. [Editor's Note: A driver
can drive a flat bottom car with its tail out in the turn and not have to worry about
losing precious downforce like they would by getting a ground effects car sideways.
That is why Champ Cars look like they are on rails in the corner and we never see the
driver step the tail out. If fans today could see drivers like Ronnie Peterson and
Gilles Villeneuve driving through a corner in four-wheel drifts they might pass out from
sheer excitement. Racing should not look like follow the leader trains on rails.
Hence ground effects must go completely.]
A good idea is to use a great range of spec parts such as ECM, brakes, transmission. Let
the cars be “no frills” cars. No paddle shifters, traction- or launch-control. Limited
testing and engines that should last a whole race weekend. All this lowers the costs and
great competition is created because success depends on driving and engineering skills
and not on fancy technical gimmicks. [Editor's Note: Paddle shifters save money.
They eliminate miss-shifts which result in broken transmissions and engines]
As I said before I prefer turbo engines over naturally aspirated engines. Should OWRS
decide to have N/A engines for their future race car they should not “destroy” that
beautiful car shape using those ugly overhead air boxes.
There are enough other ways of dealing with that subject. Just look at other series,
past and present, that use N/A engines. Toyota Atlantic cars or formula 3 Dallaras (air
intake sideways, not interfering with the shape of the car) or even F1 cars in the late
seventies. A good example is Mario Andretti’s Lotus ’79.
Another “compromise” would be an air box not higher than the rollover hoop as I suggested
in my letter “Shape of a Champ Car” that was published around the time when CART was on
the verge of switching to N/A engines and then reversed the decision.
Speaking of turbos, it’s absolutely right that racing is also about selling cars and
that not too many manufacturers use turbo engines in their cars at the moment. This
could change since turbo engines make sense economically and ecologically. Maybe we will all
drive in turbo powered cars in 10 to 15 years.
Now let me share my “vision” of a future Champ Car with you:
As you can see from the pictures the car is
significantly smaller/sleeker but still recognizable as a true Champ Car. We have a
shorter wheelbase and a shorter front end, the sidepods are lower and pulled back.
The cars is narrower and the engine cover is lowered. Using a smaller displacement turbo
engine takes up less space. That would also be the case using F1 or F2 size N/A engines.
A smaller fuel cell would also help in this regard and would bring additional
competition drama to the pit stops because of more stops.
I would not change anything about the tires because narrowing the chassis would reduce
the max. width enough to create the effect of more and better passing on the track. [Editor's
Note: The Champ Car tires are too low profile. The higher profile F1 tires
softens up the spring rate of the car and the softer feel allows the driver to hang the
tail out and feel more confident doing it. Stiff sidewall tires break away more
abruptly resulting in less tail-out driving, thereby cheating the fans out of seeing the
really great drivers hang it out.]
Well, that’s all I have to say about the chassis/engine issue. Now it’s up to everybody
else including OWRS to decide if what I have written down makes sense.
For myself, I just hope that I can still look at a future Champ Car and don’t have to
turn away in disgust like I do when I see the butt ugly IRL cars.
