MARTIN, MICH. — This month’s above normal temperatures helped raise the devil at U.S. 131 Motorsports Park for the launch of the 2018 Dodge Challenger SRT Demon.

And like the weather, this road test is not typical with driver seat time accumulated in one-quarter mile increments while piloting this factory-built dealer sold automotive monster.

The Dodge Demon nameplate is resurrected from the 1971 original, packing a 340 cubic inch V-8 engine that generated 290 horsepower and a sticker price of $2,721.

Today’s Demon comes with a supercharged 6.2 liter HEMI V-8 that runs on premium fuel to build 808 horsepower and 717 pound-feet of torque at a cost of $84,995, including $1700 gas guzzler tax.

The 2018 Dodge Demon is the first street-legal factory-production car designed to run on 100-plus unleaded high-octane fuel that boosts engine output to 840-hp and 770 lb-ft of torque.

Managing the powerplant is an 8-speed automatic transmission with Demon exclusive TransBrake system.

An available Demon Crate, valued at $6,140, cost buyers only one U.S. dollar for factory performance components that transform the street Demon into a track-purpose drag car.

Demon Crate comes with two narrow, front-running drag wheels, track tools and related equipment that can be securely transported in the Demon trunk.

The crate contents provide the first-ever front-wheel lift (2.92 feet) in a production car and affords professional drivers to eclipse a quarter mile in a record 9.65 seconds at 140 miles per hour.

Demon comes shipped from the factory with no front passenger seat, rear bench seat or trunk liner. Only a driver seat is provided.

Buyers can purchase those selected items at a cost of $1 each.

Other options set with real-world prices include leather upholstery, premium audio system, sunroof, satin black graphics package and black painted satin hood.

I test drove a 840–hp 100-octane fueled 2018 Dodge Demon on the street and took multiple passes down the drag strip.

Demon is very compliant on public roads. Managing the throttle simply takes common sense discipline.

My test car was taken off the street and brought directly to the drag strip, unmodified, for high-speed quarter-mile test runs. Its track performance is overwhelmingly impressive.

The 2018 Dodge Challenger SRT Demon is on sale now at select Dodge/SRT dealers.
