DINA 311 / Olímpico History

In 1961, DINA entered a licensing agreement with American bus maker Flxible, gaining the rights to produce two of its designs in Mexico: the Flxible Hi-Level, marketed in Mexico as the DINA 311 (nicknamed 'El Jorobado' — 'the Hunchback' for its raised rear deck), and the Flxliner, which became the Olympic Dina.

The Flxliner-derived model was officially renamed the DINA Olímpico in 1968 to honor the Mexico City Olympic Games. When Flxible exited the intercity-bus market in 1969, DINA purchased the manufacturing tooling outright and continued producing the Olímpico through 1987 — a production run of roughly 26 years that made it one of the longest-lived single bus designs anywhere. The Olímpico used a 'Torsilastic' suspension and was powered by GM 8V71 or Cummins NT/NH engines with a Spicer manual transmission.

Surviving Olímpico coaches became a fixture of Mexico's long-distance bus network well into the 1990s, operated by carriers such as Omnibus de Mexico, and the model is now a prized collector's piece among transit historians.
