It now wields somewhere in the region of 840 horsepower, eclipsed only by the sheer volume of its exhaust, which it demonstrated earlier this year during a trip to the Spa-Francorchamps racing circuit in Belgium. Take a listen, but be warned—it’s loud.
According to carcrushing, that raucous exhaust howl was just too much for the circuit’s noise limit restrictions (107 decibels for road cars), and after reverberating its eardrum-crushing 142 dB exhaust note through the Belgian hills for only three laps, the custom Ferrari Enzo was asked to leave the track.
This certainly isn’t the first time the one-off Enzo ZXX has grabbed headlines. In 2011, the Ferrari crashed into the Atlantic Ocean during the Targa Newfoundland rally, though owner Zahir Rana didn’t let a little saltwater spoil his fun. Instead, he sent the car back to Germany’s Edo Competition for repairs and requested it be built into a street-legal version of its very non-street-legal sister, the Ferrari FXX track car. Mission accomplished.
