Rezvani Tank X uses Hellcat muscle

If the 2017 Rezvani Tank was a beast, pumping out 375kW from its Hemi V8, then the new Rezvani Tank X that slams down 527kW from its Hellcat V8 is a marauder.

The Rezvani Tank X is not the most orthodox of designs, particularly given that rear-end protuberance with its sci-fi LED lights, the scalloped rear doors and the Honda Civic-style front lights and grille.

Yes, the whole shebang looks very different (read: weird) and, combined with a booming V8 soundtrack, this this urban assault vehicle will truly turn heads.

For some buyers, that's mission accomplished – even if the glorified Jeep costs $US259,000 ($A357,000).

Based on the underpinnings of the 2017 JK Jeep Wrangler Unlimited, the Rezvani Tank X gets the Star Trek exterior visuals and plenty of interior love as well, with more red leather than Eddie Murphy's getup in his Delirious comedy special.

Fancy red leather seats with a muscular abdominal motif – perfect for cashed-up gym junkies – are in evidence as part of a leather pack ($US6500), adding a cowhide-covered instrument panel and door panels. Suede headlining, a 7.9-inch touch-screen infotainment system and a head-up display are also offered.

The chassis has been completely reworked to give the Wrangler-based dirt demon go-anywhere abilities, with a six-inch lift kit, massive 37-inch off-road tyres and eight-piston brake callipers.

You can option the an 'extreme' off-road package ($US12,500) that brings adjustable FOX racing shocks like the Ford Ranger Raptor, plus Dynatrac ProRock XD60 front and 80 fully-floating rear axle set with an ARB air-locker and compressor.

Rezvani hasn't said how rapidly its 527kW/880Nm weapon accelerates to 100km/h, but it's unlikely to be as rapid as the Jeep Grand Cherokee Trackhawk, whose 3.7sec time is incredibly rapid.

That's because the Wrangler's underpinnings and gearbox aren't factory tuned – although tipping the scales at 1950kg (4300lb) means it’s a lot lighter...

Either way, the Tank X won’t be slow, but it's unlikely to make Lamborghini Huracan owners tremble at the traffic lights.

It may be a less paranoid version of the Rezvani Tank Military Edition -- which also featured a smoke screen generator, bulletproof windows and body work, and a sandy beige paint job – but the Tank X nevertheless offers a thermal imaging option ($US5500) for those times when you're cruising around town with the lights off.

Rezvani also builds the Beast X sports car, which is based on the Ariel Atom, a bonkers 600kg Brit missile which has been confirmed for sale in Australia from 2019.
