What is the fastest Dodge Viper model?

The fastest Dodge Viper by official top speed is the SRT Viper (2013–2017), which is listed at about 206 mph. On the track, the Viper ACR is renowned for extreme lap times and downforce, even though its top speed is lower due to aerodynamics. This article explains the distinctions and the records that shape the Viper’s speed reputation.

Defining speed in the Viper lineup

Speed can be measured in several ways. Here we separate highway top speed from track performance, and note notable production records along the way.

Street-legal top speeds

Below are the Viper models most commonly cited as the fastest in top speed while still being street-legal, based on manufacturer specifications and credible testing.

• SRT Viper (2013–2017): official top speed around 206 mph (333 km/h).


• Viper ACR (street-legal variant, 2010–2015): official top speed about 177 mph (285 km/h).

These figures illustrate the trade-off between raw highway speed and track-oriented aerodynamics. The standard Viper variants reach higher top speeds, while the ACR emphasizes track performance and downforce over ultimate velocity.

Track-focused variants and record attempts

For on-track performance, the Viper ACR family dominates lap times and handling on closed circuits, with specialized versions pushing the envelope beyond street legality.

• Dodge Viper ACR (2010–2015): exceptional downforce and handling, notable Nürburgring performance; optimized for track work rather than top-speed cruising.


• Dodge Viper ACR-X (track-only): further enhanced aero and weight savings for competition, not street-legal.

On closed tracks, the ACR lineup is widely regarded as the performance pinnacle of the Viper family, with Nürburgring and other circuit records underscoring its prowess.

Nürburgring and production-car benchmarks

The Viper ACR’s Nürburgring record highlighted its capability as a pure track machine, even as some street-legal Vipers boasted higher top speeds on open roads. This helps explain why “fastest” can mean different things depending on the context—the highway at-speed peak versus a measured lap time on a race course.

Summary

Speed in the Dodge Viper lineup depends on the metric you value. If you’re looking for the highest official top speed among street-legal Vipers, the SRT Viper (2013–2017) tops out around 206 mph. If you measure by track performance and lap times, the Viper ACR is the standout, delivering extraordinary handling and downforce—even though its top speed is lower—making it the benchmark for Viper performance on closed circuits. The Viper’s legacy blends extreme highway speed with formidable track capability, a combination that has kept it a distinctive legend in American performance.

What is the best model of the Dodge Viper?

The best Dodge Viper model depends on your priorities, but the Gen 2 GTS is often cited for its iconic design and raw power, while the Gen 5 ACR is widely considered the best track-focused model with its advanced aerodynamics and fully adjustable suspension. For a balance of raw feel and refinement, many point to the Gen 4, and if budget is a primary concern, the Gen 3 is frequently suggested as the best bang for the buck.

By category

• Best for raw, iconic looks and visceral power: The Gen 2 GTS (1996–2002) is a top contender for its blend of style and a more refined, yet still raw, driving experience compared to the first generation. 
• Best for track performance: The Gen 5 ACR (2013–2017) is the ultimate track car, featuring a fully adjustable suspension, extreme aerodynamics for massive downforce, and a reputation for setting lap records. 
• Best for a balance of refinement and power: The Gen 4 (2008–2010) is a great choice if you want more modern refinements than the Gen 2 but prefer its rawer feel over the Gen 5's modern amenities. 
• Best value: The Gen 3 (2003–2007) is often seen as the best value for money, offering a significant leap in performance and refinement over the first generation at a generally lower price point than later models.

Other considerations

• First Generation (Gen 1, 1992–1995): A classic icon but generally considered the most difficult to drive and live with due to its lack of modern refinements like real windows and airbags. 
• Special Editions: Models like the GT2 Championship Edition or the track-only ACR-X are highly sought-after but command a significant premium and are often less practical for regular use. 

Which Dodge Viper has a V12?

No production Viper has ever had a V12 engine; the model has always used a V10 engine. However, there is speculation and unconfirmed reports about a potential future "V12 Mamba" edition of the Viper, possibly with a hybrid powertrain, that may use a V12 sourced from another manufacturer.
