The Hellcat is proof that power isn't everything. The 2015 SRT Hellcat is only barely faster than the SRT 392 around America's legendary figure-8 track, Germany's north loop track, and Britain's famous test track. The supercharger really puts a toll onto the car's weight, and the Hellcat is really borderline a luxury car.
