transmission and other Maserati safety systems. Skyhook then calculates, and recalculates the data at least 40 times per second and instantaneously adjusts each shock absorber accordingly. When placed in the Sport mode, the suspension firms up for better cornering. Safety Both models are equipped with front and side driver and passenger airbags as well as seat belt pre-tensioners. Driving stability is provided by Maserati Stability Program (MSP) which became standard on the 2004 models and controls the engine and brakes to help the driver control the vehicle in extreme driving situations. The MSP system integrates four different vehicle systems - the anti-slip regulation traction control (ASR), the motor spin regulation (MSR), electronic brake force distribution (EBD), and anti-lock braking system (ABS). The wheels employ a high-performance Brembo braking system with light alloy four-piston calipers and cross-drilled large ventilating brake discs. Interior The Coupé and Spyder came standard with an infotainment system present on the centre console that combines audio and climate controls. An optional GPS navigation system and hands-free GSM phone were also available as options integrated into the infotainment system. Additional optional equipment includes xenon headlights, upgraded audio system and CD changer, electrochromic rear view mirror, rear parking sensors, seat heaters, and cruise control. Various interior trim packages were offered, including a leather headliner featuring a grosgrain pattern, and either a carbon fibre kit or Briar wood kit sporting wood portions of the steering wheel, door trim, and shifter. Purchasers could even order custom Maserati luggage, made to match their car's interiors. Maserati GranSport The Maserati GranSport is a sportier version of the Coupé that was first unveiled at the March 2004 Geneva Motor Show. It featured improved aerodynamics, retuned suspension, engine and transmission, and a sportier interior. Frank Stephenson, as newly appointed Director of Ferrari-Maserati Concept Design and Development, was responsible for exterior and interior redesign. An open-top GranSport Spyder with similar modifications was introduced a year later, at the September 2005 Frankfurt Motor Show. It is powered by the same 4,244 cc, dry sump, 90° V8 engine used on the standard Coupé and Spyder. However, the engine is rated at at 7,000 rpm due primarily to a different exhaust system and improvements on the intake manifolds and valve seats. Only the six-speed Cambiocorsa paddle shift transmission was offered, and was recalibrated for quicker shifts. The exhaust, equipped with bypass valves, was also specially tuned to "growl" on
