The Mazda SKYACTIV Prototype’s best
result through Watkins Glen came at its
home track, Mazda Raceway Laguna Seca,
where Sylvain Tremblay and teammate
Tom Long took seventh in the Prototype
class. As other teams vie for the Prototype
championship, Mazda Motorsports boss
John Doonan shared a message he sent
to all involved with Mazda’s P2 effort at
the halfway point of the season.
Did we set out on a challenge that
most would ask, “are you nuts?” Yes.
Did we decide to do something that
has never been done before? Yes.
Have we faced and been frustrated
by more challenges than we thought
we would? Yes, at nearly every turn
of the journey.
Have we had naysayers and people
looking over our shoulders questioning
us and our progress? Yes, for sure.
Have we made progress and will we
continue to challenge ourselves on this
project and future projects? Without a
single doubt, yes.
Like you, I want to sit on the pole, lead
every lap, and win every race. The racer
in me wants us to give the victory speech
and hoist the trophy with all of you, and
that day will come. And, the racer in me
wants to see all of your efforts rewarded
with finishes, fastest laps, wins, and
championships. I want that for all of you,
and I know we will get there.
We will continue to work together to
make progress – sometimes slower than
we would want. We will make decisions
and adjust our strategy together when
we believe it will give the most value to
Mazda and our partners. And we will
never stop challenging ourselves.
Thank you very much for what you
give time and time again, and thank
you for not giving up.

the switch to a P2 car has been a steep learning
curve, but the rate of progress is impressive.

In the battle between Daytona Prototypes and P2
cars such as the Mazda SKYACTIV-D Prototype,
the P2 cars’ superior downforce and nimbleness
through the turns are their trump card. But top-end
power still counts for a lot, hence Mazda and
SpeedSource citing that as a key development area.
