RM Sotheby's is auctioning a 2017 Dodge Viper ACR VoooDoo II Edition at its Amelia Island event on March 4, with an expected price ranging between $275,000 and $325,000. For those that missed it the first time around, the ACR VoooDoo II Edition (extra o is intended) celebrated 25 years of Viper production and the final model year of the fifth generation, and this is unit 29 of 31 built. If the standard Viper didn't have enough bite for some, this version had enough for anyone.

The Viper's V10 engine was a brute from the start, but by the time it reached the ACR VoooDoo II Edition, it measured 8.4 liters of displacement with 645 horsepower and 600 lb-ft of torque on tap. It might not be as powerful on paper as a Dodge Challenger Hellcat, but the power is everywhere through the rev range.

However, the engine was unchanged for the ACR VoooDoo II Edition. All the extra bite came from the chassis, which rides on Bilstein adjustable suspensions and relied on a bespoke Brembo braking system that used carbon ceramic brake discs to try and tame the ridiculous amount of power.

It also featured specially-made tires by Kumho for traction, and a limited-slip differential hooked to the six-speed manual. Yep, it has a six-speed manual and being able to heel-toe gearshifts is a necessary skill to not crash an ACR Viper of any type. Mechanical and electronic driver aids are minimal.

The special edition VoooDoo cars include Dodge's Extreme Aero Package, which uses removable aerodynamic devices fitted throughout the car to increase downforce. The Louvre panels in the hood extractors and over-wheel-arch vents are also removable for when things get particularly extreme.

You can't miss the carbon fiber splitters unless they're also detached, and the carbon fiber diffuser strakes on the underside of the ACR include polyethylene extensions that keep contact with the ground. It's low, mean, and sticks to the ground right up until the moment it doesn't.

Car #29 has its original Venom Black paint with a Graphite Metallic ACR driver strip with red tracer outlines. Inside, the Club Sport interior has silver accent stitching, black leather, and the requisite Alcantara materials. It also has just 1,825 miles on the clock.
