Ford Thunderbird (United States of America, 1972-1976)

In 1971 Ford launched T-bird's sixth generation, the biggest of the model. The platform used in this series was the same used in the Lincoln Continental MK IV. Also big was the engine, options went from a 7.0l or an optional 7.5l V8 unit. Their weight, dimensions and big engines translated into huge fuel consumption figures. When the oil crisis of 1973 came to the US manufactures were forced to be more efficient.
