Did Dodge make a V12 Viper?
No—the Dodge Viper never used a V12 in production; all production Vipers were powered by a V10 engine, beginning with an 8.0-liter design and later evolving to 8.3–8.4 liters.
Overview of the Viper’s engine history
The Viper line was built around a purpose-built V10 from its inception in the early 1990s. Over the years, the displacement and tuning of the V10 increased, but the configuration remained a V10 rather than a V12. This choice contributed to the Viper’s distinctive packaging, lightweight ethos, and raw, high-revving character that defined the model for its entire production run.
Were there ever V12 notions or concepts?
There were occasional discussions and concept renderings suggesting a V12 variant might be possible, but none progressed to production. The reasons cited typically included packaging constraints, costs, and the car’s established identity as a V10-powered, high-performance totem. In other words, the V12 idea remained limited to proposals and showpieces rather than an actual Dodge product.
Production status and legacy
The Viper remained a V10-powered car through its life, with production stretching from the early 1990s until the model’s discontinuation in the mid-2010s. There has been no official reintroduction of a V12 Viper since, and the nameplate is generally regarded for its extreme V10 power rather than any V12 variant.
Summary: Dodge did not produce a V12 Viper. The Viper’s identity rests on its V10 engine and stripped-down performance philosophy, while V12 concepts stayed in the realm of speculation and never reached market reality. As of 2025, no V12 Viper exists, and the model remains associated with its V10 lineage.
