Rezvani has decided to make the Tank even crazier, outfitting it with the 6.2-liter supercharged V8 engine from the Dodge Challenger SRT Hellcat. Ladies and gentlemen, say hello to the Rezvani Tank X.

The small American boutique first unveiled the Tank in October 2017 with a 6.4-liter V8 delivering 500 hp. A few weeks later, FCA’s Pentastar 3.6-liter V6 found its way into an entry-level Tank model, producing 285 hp and 260 lb-ft (352 Nm) of torque. The Tank X is the latest variant in this family and follows on from the special Military Edition introduced in July, also with a Hellcat engine.

Rezvani has opted against messing with the Hellcat engine. Consequently, it provides 707 hp and 650 lb-ft (881 Nm) of torque, more than enough to send the Tank X up and across the most difficult terrain imaginable.

The crazy just got crazier.

The Tank X looks essentially identical to the regular Tank but does come outfitted with the Off-Road Extreme Package as standard. This means it gets a 6-inch lift, Dynatrac ProRock XD60/80 axle set with air locks and an air compressor. Additionally, there’s Fox 2.5-inch internal bypass shocks, Dynatrac ProGrip front and rear brakes, and huge 37-inch off-road tires. Other noteworthy features of the Rezvani Tank X are a thermal vision system and huge 16-inch, eight-piston brake calipers at the front end.

Inside, the Tank X pictured has been outfitted with custom seats bathed in bright red leather. Customers can choose different colors if they want.

Purchasing a beast like this will cost you a pretty penny, despite the vehicle’s affordable Jeep Wrangler Unlimited underpinnings. In fact, prices start at $259,000 in the U.S.
