Hennessey Maximus turns the Ram Rumble Bee into a 1,000-HP monster

Hennessey has revealed the Maximus, a 1,000-plus-horsepower Ram Rumble Bee-based street truck with a supercharged Hellcat V-8 and a claimed 200-mph top speed.

The Hennessey Maximus Ram Rumble Bee takes the already extreme street truck to a completely new level. Based on the high-performance Ram Rumble Bee SRT, the new Maximus is expected to produce more than 1,000 horsepower from a supercharged Hellcat V-8.

Hennessey has released teaser images of the truck wearing camouflage, but several key details are already visible. The most striking feature is a massive rear wing mounted on the cargo bed, giving the truck a much more aggressive performance-focused appearance.

A supercharged Hellcat with 1,000-plus horsepower

The Maximus is powered by a heavily upgraded version of the 6.2-liter supercharged Hellcat V-8 found in the Ram Rumble Bee SRT. Hennessey says output will exceed 1,000 horsepower, making it one of the most powerful street trucks ever developed.

The company also claims a 200-mph top speed, which is significantly higher than the performance target of the standard 777-horsepower Rumble Bee.

Performance-focused design

Although the production version has not yet been fully revealed, the teaser images suggest extensive aerodynamic modifications. The oversized rear wing is the most obvious change, but additional bodywork updates are also expected.

The project appears to take inspiration from previous high-performance Ram street trucks, combining muscle-truck power with more extreme performance engineering.

Production is expected to begin next year

Hennessey plans to begin Maximus production in the first quarter of next year. Pricing has not been announced, but the truck is expected to cost substantially more than the Ram Rumble Bee SRT, which starts at $97,790.

With four-digit horsepower, a claimed 200-mph top speed and limited production, the Hennessey Maximus Ram Rumble Bee is shaping up to be one of the wildest American performance trucks in recent years.
