The Puma GTB was a front-engine, rear-wheel-drive touring car based on the Brazilian GM Chevrolet Opala components.

The name was changed to Puma GTB (Gran Turismo Brazil) for the first production version which appeared in 1973.

The GTB was powered by a 4100 cc in-line six-cylinder engine that was basically a U.S. Chevrolet six produced in Brazil.

GTB interiors were luxurious, with features such as leather seats, power windows and air conditioning.

Several aftermarket companies, including Pumakit and Superclar, produced custom body parts for the Puma GTB (the Daytona version).
