Watch the Hennessey Dodge Demon ‘HPE1000’ in action

The Dodge Demon is already a monstrous thing, with 626kW and 1044Nm in its highest output mode.

But the people at Hennessey Performance aren’t content with this, having previously announced pack to up the Demon’s outputs to 772kW/1092Nm and even stating it can wind the 6.2-litre supercharged Hemi up to 1110kW.

The version in these videos is the former, known as the HPE1000, and it sounds mental. The newest of the clips by Hennessey (top) is the best look at the car we’ve had from the firm so far, with an ‘unnamed’ employee taking the car for a spin.

“The 2018 Demon is a street-legal rocket from Dodge, but we wanted to take the car’s impressive track times to an industry leading level.” said John Hennessey when the pack was announced.

“Over the past several months we have worked to develop a low 9 second drag car that our customers can drive to the track, put on an impressive show with blistering 1/4 mile times, and then drive home in complete comfort.”

A 4.5-litre supercharger replaces the stock unit atom the 6.2-liter donk, and components in and around the engine are upgraded to handle the extra shove.

Headers and a new exhaust system help produce the thunderous wall of sound heard in the videos above.

All of this, Hennessey claims, results in a 0-100km/h time of about 2 seconds (0-60mph is in 1.9, apparently), and a quarter-mile run of 9.14 seconds.

The HPE1000 upgrade for the Dodge Demon comes with Hennessey’s one-year/12,000 mile (19,300km) limited warranty, but only 50 are to ever be built.
