The Maserati Coupé and Spyder utilise the same vehicle systems – engine, transmission, suspension, and interior driver and front passenger controls and safety equipment. Their performance specifications are almost identical, with some reviewers claiming that the Coupé has better performance due to its lesser weight and more rigid body structure, Maserati offered sixteen exterior colours, ten shades of leather interior along with the ability to select among colours for various interior details such as the piping and stitching used. Five colours for the Spyder's convertible top were also offered. Significant changes from the prior 3200 GT engine were the larger displacement resulting from an increased cylinder bore diameter and the move to a naturally aspirated intake system which replaced the twin-turbocharged induction approach Maserati had used for the previous 20 years, fundamentally because the powertrain was now Ferrari based. The crankshaft is of
crossplane design. The engine operates at a compression ratio of 11.1:1 with the eight cylinders configured in a 90° V design. The cylinder bore diameter is and piston stroke length is . The 32-valve
DOHC utilises chain-driven, twin-overhead camshafts that provide valve actuation in less than 0.15 seconds, with the intake cams being controlled by variable valve timing. The crankcase and cylinder heads are made from an aluminium and silicon alloy, giving the engine a relatively light weight of . is an
automated manual transmission. It uses a
Formula One-type gearbox, built by
Graziano Trasmissioni, with hydraulic operation and electronic management operated by F1-style paddles behind the steering wheel, similar to the system used in Ferrari sports cars. The system allows the driver to choose between four different operating modes: Normal, Sport, Auto and Low Grip. Each of these programs is selected by means of console-mounted buttons, corresponding to different types of operating mode. By switching between the Normal and Sport modes, the driver can select between different
electronic stability control settings and, if installed, different
active suspension settings. Automatic mode electronically handles shifting of the transmission, but allows the driver to rapidly revert to manual using the F1-style paddles. Perhaps the most highly regarded option is a computer-controlled suspension damping system called "Skyhook". This adaptive damping system uses coil-over shock absorbers and a set of six
accelerometers that continually monitor the movement of the wheels along with the car's body and transmits this information to a control unit. The vehicle's computer analyses this data and coordinates it with the Cambiocorsa 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. ==Maserati GranSport==
