Mazda’s previous ALMS P1 and P2
programs made use of Lola coupes,
so it was a natural fit to resume the
connection for the new P2 project
through Ontario, Canada-based
Multimatic, which took over
production when the British firm
ceased trading in 2012.
“We chose this chassis for a
couple of primary reasons,” Sylvain
Tremblay notes. “We’ve worked with
Multimatic for more than 14 years
with their Dynamic dampers and
they’re a great group, with
motorsports experience in all major
road racing series. The coupe
concept is the way of the future and
we wanted a ‘known’ car, because
developing a chassis and a new
engine is a tall order. This way we
focus on the SKYACTIV diesel, but
have a great book of knowledge
available to us on the chassis.”
Aerodynamics govern every
aspect of the Mazda P2’s
performance, and the need to
adequately cool the high-heat
diesel packaged in the back of the
coupe was of utmost importance.
Multimatic’s experience and
resources help SpeedSource in
those areas and more, making the
Canadian firm an invaluable partner.
“The aero portion of the
demands of the diesel was the
unknown, and it’s still a major area
of development,” Tremblay says.
“The heat rejection demands are
substantial, and to run a car that
was designed to accept non-diesel
engines has been a challenge, but
we’re making gains at every event.
So much so that we are able to run
with more power than ever
before, and for longer periods of
time than just a couple races ago.
“It’s ongoing, never ending; the
entire engineering staff is making
gains and it’s visible on the data and
the track. Multimatic is a one-stop
partner with expertise and capacity
in wind tunnel, composites, shaker
rigs, design and development.
They’ve been a tremendous help
MULTI-TASKING WITH MULTIMATIC
in our progress so far.”
Tremblay’s last comment
provides the best portrait of
Mazda’s P2 effort this season. A
massive Prototype undertaking by
the GT experts at SpeedSource
came with a significant learning
curve. The SpeedSource-developed
engines have also taken time to
mature, and understanding the
unique cooling needs for the
bi-turbodiesel has evolved through
the season. Progress is the theme
for 2014. But come 2015, the
narrative will switch to results.
The SKYACTIV-D Prototype’s
2.2-liter, four-cylinder diesel
engine (RIGHT) includes the first
racing application of compound-turbo, direct-injection technology.
