Ferrari 599 GTO by Novitec Rosso

The Ferrari aficionados at Novitec Rosso have unveiled a new tuning program for the 599 GTO.

While the car certainly wasn't lacking in performance, the tuner outfitted the 6.0-liter V12 with twin superchargers, a new intake manifold, enlarged fuel injectors, high-flow air filters, a massive intercooler, and stainless-steel sport exhaust system with 90mm tailpipes. Thanks to these tweaks, output climbs to 888 PS (653 kW / 876 hp) and 862 Nm (636 lb-ft) of torque - an increase of 218 PS (160 kW / 215 hp) and 242 Nm (178 lb-ft) of torque. This enables the car to accelerate from 0-100 km/h in 3.2 seconds, 0- 200 km/h in 9.1 seconds, and onto a top speed in excess of 340 km/h (211 mph).

On the styling front, the car features a silver and yellow paint scheme which is reminiscent of the Ferrari 250 GTO that won the 1964 Tour de France. Additionally, Novitec Rosso installed lowering springs, a front-axle lift up system, and lightweight wheels (which measure 21-inches front and 22-inches rear) with Pirelli PZero tires.
