Dodge Viper Show 2015

The Vipers gathered at this 2015 show were living on borrowed time, even if nobody knew the exact date yet. This piece looks at what made the final-generation Viper, 645 horsepower, naturally aspirated, six-speed manual, the angriest version of a car that never once used a turbo or supercharger in 26 years of production.

Vipers Going Loud.. Loud Revs.. Hard Acceleration.. Great Sound!

By 2015, everyone at that Viper show already suspected what nobody wanted to say out loud: the clock was running out. Two years later, the Conner Assembly plant would close for good, ending a 26-year run and roughly 31,000 cars built one at a time, with no turbo or supercharger ever bolted on for a single one of them. The Vipers revving in that 2015 crowd were some of the last and most powerful the model would ever produce. What made this final generation different from every Viper that came before it?

The Last Viper Was Also the Angriest

The fifth and final generation ran from 2013 through 2017, launching as the SRT Viper with an all-new 8.4-liter naturally aspirated V10, modern vehicle dynamics systems, and a genuinely upgraded interior. A 2015 update brought output to 645 horsepower and 600 lb-ft of torque, all sent through a six-speed manual to the rear wheels, with a top speed north of 200 mph — numbers that made it the strongest series-production Viper Dodge ever sold.

Five Generations, One Constant Idea

Every Viper generation, from the original 1992-1995 cars through this final run, stuck to the same formula: a big, naturally aspirated V10 with nothing but displacement and revs doing the work. That engine grew from 8.0 liters and 400 horsepower in Gen 1 to 8.4 liters and 645 horsepower in Gen 5. Across all five generations and 26 model years, Dodge built somewhere around 31,000 to 32,000 Vipers total before Conner Assembly closed its doors permanently in 2017.
