The Zonda Revolucion was a special, "final version" of the Zonda that was released in 2013 only to special clients and family members, during “Vanishing Point 2013”, the international Pagani gathering. Mercedes-AMG developed the engine, a 6. 0 L (366 cu in) V12 that produced 800 PS (590 kW; 790 hp) and 729 N⋅m (538 lb⋅ft) of torque, connected to an Xtrac 672 6-speed transversal and sequential gearbox that could change gears in 20 milliseconds. The whole car weighs less than a Mini Cooper, thanks to a carbotanium tub at its core, resulting in a 1,070 kg (2,359 lb) kerb weight. The Revolucion also features DRS (Drag Reduction System), and two different operating modes: one that's available with a minimum speed of 100 km/h (62 mph), and another that changes the rear wing, switching the maximum and minimum down-force settings. Pagani's chief test driver Davide Testi claimed that the Revolucion could be a full 15 seconds quicker than the Zonda R around the Nürburgring. Only five of these cars were built, and they were priced at €2. 2 million before taxes.
