MAZDA ROAD TO INDY
utilizes a fly-by-wire throttle system and
Cosworth SQ6 engine management
system, and packs an impressive 275hp.
The aero package is more sophisticated,
including an adjustable dual-element rear
wing and single-plane front wing with
adjustable flaps. However, most of the
downforce is generated by the floor,
which should translate into good racing.
Larger American Racing Technomesh
monoblock alloy wheels (13in. x 10in.
fronts and 13in. x 12in. rears) are another
visual clue that the PM- 18’s performance
is the requisite step up from the USF- 17.
“This car wants to be pushed,” says
Miller. “It definitely wants to be driven
hard. And with the upgraded engine, it
has some serious legs. At Mid-Ohio, we
were 10mph faster than the current car
An additional, unexpected change has
been introduced in the form of a modified
gearbox, which was mandated after the
first tests with the more powerful engine.
“The USF2000 gearbox just wasn’t
Cosworth’s CFW277 steering wheel with integrated dash
and gear change paddles allows drivers to work with the
type of high-tech systems they’ll use at their destination.
The monocoque’s the same, but visual
tweaks between the PM- 18 (TOP) and
USF- 17 include different front and rear
wings, air intake, and bigger wheels.
SAME, BUT DIFFERENT
Safety was at the forefront of the design
of the USF- 17 car, and that same
thinking has been carried up a class to
the new Pro Mazda Tatuus PM- 18. The
carbon composite/aluminum honeycomb
monocoque meets all current FIA F4
safety standards, but in preparation for
racing on ovals, the PM- 18 is built with a
double front bulkhead and side intrusion
panels. A HANS-compliant IndyCar head
restraint, front and rear wheel tethers,
and beefier suspension and uprights all
make for a safety package optimized for
the versatile challenges its drivers will face.
But the world-class safety standards
don’t stop with the car. All Mazda Road
to Indy categories are overseen by
IndyCar’s renowned race control, as well
as the crack Holmatro Safety Team.
“IndyCar provides a full IndyCar level
of support at every event we go to, and
the Holmatro guys are in a class by
themselves,” says Dan Andersen, CEO
of Andersen Promotions.
“I look around the world at other
incidents that happen, and the first
thought that usually comes into my
head is, ‘Man, the Holmatro guys would
have been there so much faster.’
“They’re just an amazing bunch of
guys. I’m so glad that we have that full
complement looking out for us on all
three Mazda Road to Indy levels.”
No driver wants to meet the Holmatro
Safety Crew – doing so usually means
they’ve had a bad day. But if something
does go wrong, there’s nobody better than
these guys coming to help you out.
