2013 Hennessey Grand Cherokee HPE800
In a list of respected aftermarket tuners, Hennessey has reigned supreme in offering audacious efforts helping push domestic muscle to the next level. From his well-documented efforts with the now defunct Dodge Viper, Hennessey’s portfolio has diversified over time as witnessed by this Grand Cherokee HPE800. Defined by a twin-turbo bored out Hemi V8 measuring in at 7.0L, the 805 hp SUV now achieves 0-60 mph sprint times of 3.1 seconds. Upgraded brakes thanks to 15.1 inch Brembo brakes help in the stopping. Of course additional highlights include suspension upgrades, new lighter wheels, a carbon fiber front end, custom interior, and an Alcantara steering wheel. The HPE800 will set you back $235,000 USD starting next year.
