The car in the Video is an EV12 7.3S by brabus but MB aslso had their own version of some of their models with the legendary V12 (which eventually ended up in the Pagani Zonda C12 7.3S without any significant changes)

All have 1 thing in common, the mighty mercedes M120 6.0 60 degree V12 which has been nored out to approx 7.3L and have had the internals (and externals) changed t bring them up in terms or relative output.
the 7.3L V12 was one of the best kept (and rarest) secrets at Stuttgart (and bottrop). I guess the cat's out of the bag now... (Y)
