Dallara technical director Andrea Toso on designing a car that has to deliver, whatever the track type.
INDYCAR’S NEW ALL-ROUNDER
he concept for the DW12 used many
things that we’d already learned in the
IZOD IndyCar Series, and the previous car
had been used in road racing beginning in
2005, so these areas were known to us.
What I’m saying is that the new Dallara is
a multi-purpose car, but it was not such a
big step for us to create it to race on the
road courses and the ovals.
And remember, this is what Indy car
racing was for many, many years. I think the
DW12 is a return to this, where the car is
designed to be good on every type of track.
Most drivers compare the current car
with the previous one, but the last car
was designed in 2002, so it seems like
the new car is a big step. Since ’02, we
have been designing a lot of cars for a lot
of different series – GP2, GP3, sports cars,
and many consulting contracts – and the
previous car also went through a lot of
development. It has been a continuous
evolution of design for Dallara, and now we
have very advanced CFD, the driving
simulator, and the newest software design
tools, too. For some people, the D W12 is
a big change, but for us, it is more of a
progression, not a revolutionary concept.
Where this car is different is that it does
not have competition. If there was
competition from another manufacturer,
the costs would be very high and you
would see a situation like it was in the past:
new floors for every race, new wings,
special suspensions, and everything
designed for each of the circuits. We could
Introduced in 2003,
the IR07 was
designed to race
on ovals. When the

in ’05, Dallara made
a conversion kit
for the IR07 that
served through to
the end of 2011.
JACK OF ALL...
not do this with the D W12, because the
series wants to keep costs very low, but
we’ve still put a lot of thought into
maximizing the performance in every way
possible. We did not design the car to be
good only on one type of circuit, so it has
been a great challenge to make the new
car faster with less power. This has been
the biggest area of work for Dallara.
To remove so much drag in order to
bring the car up to the required
