The wildest Viper starts at $122,490, including a $2,495 destination charge and $2,100 gas-guzzler tax, according to Dodge spokeswoman Kristin Starnes.
In comparison, the base 2015 Viper SRT starts at $89,190, including shipping and gas-guzzler tax.
The Viper ACR, which is short for American Club Racer, is a trim level of the high-performance Viper. Production of the Viper ACR will begin in the third quarter at Detroit's Conner Avenue Assembly Plant, with cars arriving in showrooms a short time later.
"Viper enthusiasts can now place their orders," Fiat-Chrysler said in a statement.
The top-of-the-line Viper is powered by a 645-horsepower 8.4-liter V10 engine linked to a standard Tremec six-speed manual transmission.
Details include a unique track suspension, new carbon-ceramic brakes with six-piston calipers, lightweight carpet, minimal three-speaker audio system and manual seats.
An optional ACR Extreme Aero package, which will be available later in the model year, includes a carbon-fiber rear wing, unique SRT hood with removable louvers and additional dive planes.
Edmunds says: This is the Viper taken to its limits in both performance and price. If you want a weekend track car with the ability to outrun even the most expensive European exotics, this Viper has all the ingredients.
