Hennessey has released a new video of their Jeep Grand Cherokee SRT8 running the quarter mile.

Equipped with the HPE650 package, the car accelerated from 0-60 mph in 3.9 seconds and ran down the track in 12.6 seconds at 110 mph (177 km/h).

While the standard Grand Cherokee SRT8 has 470 bhp (350 kW), the HPE650 package adds ported cylinder heads, a custom air intake and a TVS2300 supercharger. Hennessey also adds stainless steel long tube headers, an upgraded fuel system and an optimized ECU. Thanks to these modifications, the 6.4-liter HEMI V8 engine develops 650 bhp (485 kW).

The package also includes Hennessey-branded floor mats, special badging and individually-numbered plaques. Customers can also add an upgraded interior as well as a tire and wheel package.
