The GTO became a
separate Pontiac model (model number 242) in 1966, instead of
being an "option package" for the Tempest LeMans like its
predecessor. The entire GM A-body line was restyled that year,
receiving a more curvaceous design with raised rear fender
lines for a "coke-bottle" look and a slightly "tunneled"
taillight. The taillight featured a slatted cover that was only
seen on the GTO.
The GTO was
available as a sports coupe (with B-pillars), hardtop (without
B-pillars) and convertible.
The 1966 model year
is considered by many to be the most iconic of all
GTOs.
