Troller Veículos Especiais S/A (Troller) is a manufacturer of off-road vehicles in Brazil. It was founded in 1995, in Horizonte, Ceará. Troller T4 3.0 Turbodiesel is Troller's flagship. It has featured successfully in several rally races around the world, including the Dakar Rally.
The Troller company started in 1995, by Rogério Farias. In April 1996, the first prototype was built. In 1997, Troller was bought by the entrepreneur Mário Araripe, who formed a partnership with Rogério Farias, and the first gasoline-powered T4s were built. The mass-production of the vehicles started in 1999, when a factory was built.
In 2005, a manufacturing plant opened in the African country of Angola to build the T4 for the African market.
Ford do Brasil announced in January 2007 the acquisition of Troller for an undisclosed price.
On the 14th of December 2009, a Troller made the news when it cleared São Paulo's flooded city streets during a live broadcast.
