the new face of truck racing
helps keep developments costs
reasonable, especially given that Truck
Series teams work on budgets that are a
fraction of what the Cup teams spend.
“We wanted a new look, but we didn’t
want to completely reinvent the wheel, as it
were, by completely changing the platform
we’re racing with,” says Pierantoni.
On the new Silverado, the front splitter
is the same as used on the Nationwide
cars, while the front lower fascia is shared
by all the manufacturers. From the front
bumper to the windshield, the parts and
pieces are unique to each manufacturer.
Turner-Scott Motorsports functioned

all three of the race vehicles used in
naScar’s national touring series have
their own different handling and
performance characteristics. kyle
Larson, who has driven in the naScar
Sprint cup, nationwide and camping
world truck Series, explains.
“the trucks have a lot more downforce
and side force, and they have a lot of
drag with the big spoiler on the back,”
says Larson, who will drive the no. 42
chip ganassi racing with felix Sabates
chevrolet SS full-time in 2014 Sprint cup.
the trucks and the nnS cars also
have tapered spacers that limit the flow
of the air-fuel mixture into the engine.
“they have about 200 less
horsepower than the cup cars,” explains
Larson. “the trucks aren’t as quick and
you’re in the gas pedal a lot more. with
the cup cars, you have a lot more
power, so momentum is less important.”
the added downforce lets the trucks
stay planted in the corners, but the
slab-like sides of their bodies make it
easier for the truck on the outside of a
fast turn to pull the one on the inside
around and cause it to spin.
“it takes the air off the side of your
truck and tends to suck you around
easier,” says Larson, who won in the 2013
truck Series at rockingham (BeLow).
in other ways, the trucks are the
easiest to drive of the three. “the
nationwide cars have less downforce
than the trucks,” he says, “so you have to
lift off the throttle in the corner at most
place, whereas in the truck you can run
wide open in most places for five or
10 laps until your tires start going away.”

BEHIND THE WHEEL
Chevrolet. “We supplied parts and they
helped us put the trucks together for
submission testing,” explains Pierantoni.
Make no mistake about it, the Truck
Series is very important for Chevrolet, but
not just from a marketing perspective –
although that in itself is a crucial factor.
“Winning certainly carries over into the
showroom,” adds Pierantoni. “If it didn’t
carry over, we wouldn’t be doing all the
things we’re doing in NASCAR racing.”
The Truck Series and the NASCAR
Nationwide Series also help support the
Sprint Cup effort on multiple levels.
“They’re important to our Cup teams,
where they have customers who lease
engines and have engineering and technical
alliances with them,” says Pat Suhy,
NASCAR group manager for Chevrolet
Racing. “Plus our teams use those series as
training grounds for pit crews, crew chiefs
and other team members. We also use the
series for developing our technology, so
they’re very meaningful for us, too.”
