Citibus is the public transportation bus and paratransit system which serves Lubbock, Texas.

In addition to regular bus routes, it has a partnership with Texas Tech University to run shuttle buses on school days and game-day events.

Citibus has unveiled six diesel-electric hybrid buses that will begin service on city routes.

Managers hope the buses will use 60 percent of the fuel that their older, larger peers consume running customers across the city.

The smaller buses seat 23 passengers, can support full-size wheelchairs and will run on all but two city-based routes.
