The '66 Mustang were very slightly
restyled. Most noticeably, a floating horse was added to the front
grille. Other changed for the '66 included a redesigned gas cap, bright
hood lip molding on all models, standard rocker panel moldings (except on the
2+2), standard back-up lights, redesigned side chrome spires (which were
deleted on the GTs and those with accent pinstripes) along with revised style
steel wheels. Now a chrome trim was used on the wheel.
Different upholstery patterns and colors were available in the interior of the 1966 Mustang along with
a five-dial instrument cluster. Padded sun visors were standard on every Mustang.
Standard engine for the Mustang continued to be the 200ci six-cylinder with the three-speed manual transmission.
The Cruise-O-Matic automatic transmission now became available with the "K" code, of which only 5,469 "K" code Mustangs were produced.
Mustangs exported to Germany were named the T-5 Mustang. All Mustang emblems and logos were removed since "Mustang" was used by another manufacturer. The T-5 emblem could be found on both fenders.
