The 2006 Maserati Quattroporte F1 (also known as the DuoSelect or Cambiocorsa) features a 6-speed sequential manual transmission designed to provide a performance-oriented, race-car-like driving experience. This system, which lacks a traditional clutch pedal, uses electro-hydraulic actuators and steering-wheel-mounted paddle shifters for gear changes, offering shifts as quick as 40 milliseconds in the Sport GT version's 'Sport' mode. Paired with a 4.2L V8 engine that produces around 396 horsepower and a rear-biased weight distribution, the F1 transmission contributes to the sedan's agile handling and an engaging, enthusiast-focused drive with a distinctive exhaust note. However, the F1 transmission in the 2006 Quattroporte is also known for its significant compromises in daily driving comfort and long-term reliability. In automatic mode, shifts can be jerky and abrupt, as the system momentarily cuts throttle between gears, making it feel unrefined compared to the smoother, traditional automatic transmissions (ZF) that Maserati introduced in later models. The clutch assembly is prone to wear, often requiring expensive replacement, especially if the car is not driven with a specific, aggressive manual-shifting technique, which many owners cite as a major drawback. This model also lacks a "Park" mode, relying instead on remaining in neutral and using the parking brake when stopped.
