Since each Pagnai that leaves the factory is built to order and is therefore highly customized by its customer, they are all a bit different. You can notice that in the paint jobs and interior features, and as it turns out, the exhaust noise as well.
Here we have some onboard footage from a Pagani Zonda Tricolore ride with Marchettino, and even though this car has the same AMG V12 as other Zondas, it sounds different, and more awesome, than, say, a Zonda F. Check it out:
A tribute a the Italian Air Force aerobatic team, Pagani Zonda Tricolore is a limited edition of just three units based on the Cinque model. The 7.3 liter AMG V12 engine in the Tricolore punches 670 horsepower, delivered to the rear wheels via a sequential gearbox. Performance figures for this model read 0 to 100 km/h in under 3.5 seconds and top speed over 350 km/h.
