In fact, that 670hp figure beats even the Mercedes SL65 AMG Black Series in terms of overall power, and the GT2 is considerably lighter. Acceleration in the 9ff GT2 is brutal: 3.6 seconds to 62mph (100km/h), 9.8 seconds to 124mph (200km/h) and just 25.8 seconds to 186mph (300km/h) - faster than both the Ferrari Enzo and the Porsche Carrera GT.
The V670 turbochargers are only part of the story, but they are an imporant part. A custom 9ff air intake manifold helps the turbos breathe, while in-house designed and built racing headers and exhaust system helps flow through the engine. A custom valve on the exhaust allows the driver to choose from a tamer near-stock sound level or a wide-open race car sound for track use. An ECU tune and raised rev limiter to 7,200rpm finish the engine modifications.
A lightweight single-mass flywheel and an organic-coated racing clutch combine easy driveability with better performance, and the coil-over suspension has been optimized for lap times at the Nordschleife. That track's notoriously bumpy and uneven surface has led to a near-race-level performance car with characteristics that 9ff claims make it comfortable to drive daily - provided the accelerator is used gently.
