One of the most popular tracks in NASCAR, this all-concrete
construction is similar to Dover, except far shorter. Although
the track still advertises the banking as 36 degrees, which
would make it the most steeply banked track used by NASCAR, it
is now accepted that the actual banking ranges from 24 to 30
degrees after the track's most recent resurfacing in 2007
(even before the resurfacing, there was some dispute as to the
accuracy of the measurement). However, the track is so short
that speeds here are far lower than is typical on most NASCAR
oval tracks, but very fast compared to other short tracks due
to the high banking, making for a considerable amount of
"swapping paint". Also, the initial starting grid of 43
vehicles extends almost halfway around the track, meaning that
the slower-qualifying cars begin the race almost half a lap
down. Another anomaly is that the short overall length means
that there are two sets of pits. Until 2002, slower starters
were relegated to those on the backstretch. In 2002, the rules
were changed to form essentially one long pit road. During
caution periods, cars wishing to pit must enter pit road in
turn two, drive all the way down the back stretch, through
turns three and four and down the front stretch, exiting pit
road in turn one. This rule eliminated the inherent
disadvantage of pitting on the back stretch. Pit stops under
green flag conditions have different rules. Cars with pits on
the back stretch enter the pits in turn two and exit in turn
three; Cars with pits on the front stretch enter the pits in
turn four and exit in turn one. Since the new pit rules were
instituted, several drivers have made major mistakes during
green flag pit stops by driving through both pit roads when
only one is necessary for green flag pit stops.
The 2006 Disney-Pixar film Cars used Bristol Motor Speedway as
the basis for the racetrack seen in the film's opening race,
the "Motor Speedway of the South." The size of the track was
increased to give it a more stadium-like appearance.
For many years, teams were unable to park their
transporters inside the infield. Nor did the track have any
significant garage area. Team transporters were parked in a
lot outside of the track. During racing periods, crews and
participants were landlocked by the track, and thus, unable to
return to the transporters for spare parts, repairs, or rest.
In the early 1990's, the infield was reconfigured, and
completely paved. Teams began parking the transporters in an
orchestrated, extremely tight arrangement that takes several
hours, and highly skilled drivers, to accomplish. Teams are
now able to work out of their transporters in the same fashion
as other facilities.
On March 25, 2007, the first race featuring NASCAR's new
car design, the "Car of Tomorrow" (COT) was run at Bristol
Motor Speedway. Jeff Gordon won the first ever pole award in a
Car of Tomorrow, and Kyle Busch won the race, becoming the
first winner in the COT.
