Few engines carry the kind of cult status that the thunderous Dodge V10 does. While most enthusiasts know the Viper V10 from its natural habitat under the long hood of America’s most notorious sports car, Spania GTA had a bolder idea: drop a heavily modified version of that engine into a lightweight, track-focused machine that would leave the Viper itself in the dust. The result was the GTA Spano, a low-volume supercar from Valencia that deserves far more attention than it typically gets.
