The Dodge Challenger SRT HELLCAT is one of the most powerful cars on the market, but that power comes with some drawbacks. Perhaps the biggest issue is the car's high fuel consumption. The SRT HELLCAT can easily consume more than 20 liters of fuel per 100 kilometers, and this can be quite costly for the owner. Another issue is the car's handling. The SRT HELLCAT is a powerful car, but it can be quite difficult to control at high speeds. Finally, the car's suspension can be quite harsh and uncomfortable, especially on rough roads.
