Remember Dartz, Latvia’s best known and most outlandish vehicle manufacturer? Can’t blame you if you don’t, but they are back with a new project.

Their latest creation certainly true to their ways: an over-the-top body kit that makes the Hummer H2, on which it’s based, hard to recognize. As Top Gear has learned, the “Black Stallion” (named after the famous Sikorsky helicopter) is a one-off built for a movie Dartz is unable to reveal at the moment.

The sinister-looking bodywork is made from Kevlar and carbon, as well as a special hexagonal carbon fiber. The unique vehicle features the stock Hummer H2 V8 engine which apparently is fast enough to shoot chasing scenes.

However, the Latvian company can put a Hellcat engine in the thing should the customer wish so, along with a new transmission and modified suspension setup. Despite the use of Kevlar and carbon, the Prombron built for the movie is 500 kg (1,102 lbs) heavier than a standard Hummer H2.

The road-going version is said to get a carbon-Kevlar body instead, making the ridiculous curb weight a little less so, and the SUV more manageable for driving outside of movie sets.

The folks from Dartz say a “Black Stallion” could become available for at least €300,000 ($331,075), which is an obscene amount of money for what is essentially a Hummer H2 with some aftermarket bits and pieces and a questionable body kit.
