The Troller T4 was a four-wheel drive/rear-wheel drive vehicle made by Troller. It was only available as a two-door car with a fiberglass body and steel chassis, with a design inspired by the Jeep. It has standard 4WD, a 5-speed manual transmission and Dana axles. The engine is a 3.0 L turbo Diesel built by MWM and was introduced in 2004.

In 2007, Ford Motor Company purchased the company for R$400 million (2007) (US$205.44 million); In 2014, the T4 received a major redesign, was built on a shortened version of Ford's T6 platform for the global Ranger. The version looked more like the modern form of the Jeep Wrangler and early Bronco models.

In January, 2021, Ford Brazil ceased its operations; On October, Troller's assembly plant was deactivated. Ford tried to sell the company, initially, but after an extended negotiation with the Ceará government, Ford Motor Company, its branch headquarters, decided to not sell the division.
