The 2018 Dodge Challenger SRT Demon: Redefining Muscle Car Dominance

Dodge Challenger SRT Demon

When Dodge set out to create the ultimate factory-built drag racer, they didn't just raise the bar - they obliterated it. The 2018 Dodge Challenger SRT Demon stands as a monument to American muscle, holding the title of the most powerful production V-8 ever created. With its earth-shaking 840 horsepower and 770 lb-ft of torque, this beast redefined what's possible in a showroom-stock vehicle.

Unprecedented Power: The Heart of the Demon

At the core of the Demon's terrifying performance lies a supercharged 6.2L HEMI® Hellcat V-8 engine that's been radically enhanced:

Engineering Marvels: How Dodge Created a Drag Strip Monster

The Demon isn't just about brute force - it's a masterpiece of precision engineering designed specifically for straight-line dominance:

Transmission & Drivetrain

The TorqueFlite 8HP90 8-speed automatic transmission features a TransBrake system that allows the engine to rev against the brake for perfect launches. The rear axle receives a 3.09 final drive ratio and a limited-slip differential optimized for drag racing.

Suspension & Chassis

Dodge engineers developed a specialized suspension with adjustable dampers that transfer weight more effectively during launches. The Demon's unique "Drag Mode" automatically adjusts suspension settings for optimal weight transfer.

Weight Reduction

Every gram mattered in the Demon's development. Dodge removed 218 pounds compared to the Hellcat through measures like:

  • Lightweight forged aluminum wheels
  • Removal of rear seats (optional)
  • Thinner rear glass
  • Lightweight Brembo brakes

Exclusive Demon Features

Beyond its record-breaking performance, the Demon boasts several unique characteristics that set it apart:

Demon Crate

Each Demon came with an optional "Demon Crate" containing:

  • Drag radial tires for track use
  • Front runner wheels for weight reduction
  • Specialized tools for drag racing setup
  • Numbered plaque matching the VIN

Production & Collectibility

With only 3,300 units produced for the U.S. market (plus 300 for Canada), the Demon has become an instant collector's item. Each vehicle features unique badging and serial numbering, with demand far exceeding supply upon release.

How the Demon Compares to the Hellcat

While sharing the same platform, the Demon represents a significant evolution from the Hellcat:

Feature Hellcat Demon
Horsepower 707 hp 840 hp
Torque 650 lb-ft 770 lb-ft
0-60 mph 3.6 seconds 2.3 seconds
1/4 Mile 11.2 seconds 9.65 seconds
Production Volume Unlimited 3,300 units

Ownership Experience: Living With a Demon

While engineered for the track, the Demon remains surprisingly streetable:

Daily Driving

Despite its extreme performance, the Demon offers selectable drive modes that tame the beast for regular use. The "Street Mode" limits power to a mere 500 hp for better traction in normal conditions.

Fuel Requirements

To achieve its full 840 hp output, the Demon requires 100+ octane race fuel. However, it automatically adjusts performance when running on 91 octane pump gas, still delivering an impressive 808 hp.

Insurance & Maintenance

Due to its limited production and extreme performance, Demons typically command higher insurance premiums than standard Challengers. Maintenance follows similar schedules to Hellcat models, though track use will increase service frequency.

The Demon's Legacy in Automotive History

The Challenger SRT Demon represents a watershed moment in factory performance:

  • First production car to lift its front wheels during acceleration
  • Holds 13 official NHRA records for production vehicles
  • Featured in numerous automotive publications as "Car of the Year"
  • Inspired an entire generation of ultra-high-performance muscle cars

Where to Find a Demon Today

Due to their limited production and growing collector status, finding a Demon requires patience:
