Maserati Range Technical Updates July 2012 Training Documentation for Maserati Service Network Maserati Range Technical Updates Foreword Foreword Foreword The aim of this document is to provide Maserati Technicians with essential information about the new contents introduced with the restyling of the GranTurismo MY 13 and the main updates relating to the Maserati range. The product range (GranTurismo, Quattroporte and GranCabrio/GranTurismo Convertible) is presented for each MY, starting from MY09 and working up to MY13, discussing the main new contents and the relative characteristics. The chapter focusing on each MY also includes the data about the engines installed on the range (valve timing control device type, mechanical timing values, electrical timing values, etc.). The aim is to set out the updates introduced in chronological order, with the relative data, so that the technician can follow the progression of the changes made. This manual is provided as an addition to the Maserati Academy training programme. Maserati Academy 2 Maserati Range Technical Updates Table of Contents Table of Contents MY09 4 0.

General information 2009 Range: The new MY09 version of the Quattroporte was the outcome of a thorough renewal project, in terms of both styling and engineering. Five years after the model’s launch and with more than 15,000 cars sold, Maserati decided to offer reinterpretations of the car, to aim for ambitious new goals. Pininfarina further refined the Quattroporte’s elegant design with more modern lines and clearer references to the distinctive features of the GranTurismo family. Under the bonnet, as well as the 4.2L V8 engine the more powerful 4.7L version now also became available, still in combination with the automatic 6 speed gearbox. The GranTurismo S (M145GL) joined the Maserati range exactly one year after the launch of the GranTurismo, with Maserati revealing the first heir to the famed GT to the public. Created for those in search of a more dynamic version of the GranTurismo already on the market, the GranTurismo S, fitted with a 4.7L V8 engine and robotized rear-mounted gearbox, was more aggressive while still keeping faith with the GT tradition by delivering high levels of comfort to four occupants during long journeys. The GranTurismo S Automatic (M145HL) was the logical completion of the Maserati GranTurismo range. The model presented in 2009 combines the performance of the 4.7L engine, the most powerful in the range, with the unique comfort of ride provided by the automatic gearbox. The 2009 range comprises the models listed below: GranTurismo (M145) Range • GranTurismo (M145ML) • GranTurismo S (M145GL) Robotized • GranTurismo S (M145HL) Automatic Quattroporte (M139) Range • Quattroporte (M139HQ) • Quattroporte S (M139IQ) • Quattroporte SPORT GTS (M139MQ) Maserati Academy 4 Maserati Range Technical Updates MY09 Quattroporte (M139) The Quattroporte, the car that reinvented the luxury sports saloon segment, is a real Maserati masterpiece. Five years after the launch, the new MY09 version was the outcome of a thorough renewal project, in terms of both styling and engineering. Pininfarina further refined the Quattroporte’s elegant design with more modern lines and clearer references to the distinctive features of the GranTurismo family. Under the bonnet, as well as the 4.2L V8 engine the more powerful 4.7L version now also became available, still in combination with the automatic 6 speed gearbox. The new Quattroporte range included three variants: • Quattroporte: the quintessential Maserati luxury saloon. The car with wet sump 4.2L engine, provides a smooth ride and driving comfort. • Quattroporte S: the range’s flagship. This car features the 4.7L engine with improvements to the chassis dynamics to suit this higher-powered unit. With the Quattroporte S luxury reaches new heights. • The Quattroporte Sport GT S: launched in January 2009, this was the most successful synthesis of luxury saloon and high-performance sports car Maserati had ever produced. The modifications to the chassis, gearbox and exhaust system maximised handling and performance, for even greater enjoyment at the wheel. Maserati Academy 5 Maserati Range Technical Updates MY09 Exterior The stylistic changes included: updated front and grille, new front and rear light assemblies, new rear bumper, new wheel rim design, new rearview mirrors and completely restyled underdoor moulding covers. The front and rear light assembles are both of LED type, further underlining the Quattroporte's dynamic character. External lights The Quattroporte MY09 is fitted with new lighting systems at both front and rear. The front light assemblies now feature beam regulation, a solution similar to that used on the GranTurismo (self-adapting headlamps). • Bi-xenon type • 17 LED direction indicators • Flash to pass headlamp • 12 LED stop function • Parking light with DRL function • 2 LED parking light • 10 LED direction indicators • 2 LED rear fog lights • Integral sidelights • 1 LED integral sidelight • Headlamp washing system • Reversing light • Automatic attitude monitoring and system with automatic beam adjustment on bends Maserati Academy 6 Maserati Range Technical Updates MY09 Interior In its interiors, as well as the availability of new combinations for personalising the finishes, the Quattroporte MY09 features a state-of-the-art InfoTainment system with a vast range of multimedia functions. The interior of the new Maserati Quattroporte delivers an even higher level of comfort thanks to significant changes to the driving seat ergonomics, involving the new seat shape, the use of the multifunction steering wheel with racing grip, the controls closer together on the central console, the new graphics of the instrument panel, and a small storage compartment in the central tunnel. Quality of life in the rear seats is high, with excellent noise insulation and no vibrations. The new Quattroporte offers great flexibility in rear seat setup thanks to a large number of optionals, such as independent electric adjustment: the reach adjustment (10 cm) and separate tilt setting allow each occupant to find the position they like best, and travel in complete comfort. Another rear seat optional is heating, which also includes ventilation and massage. The new Maserati Quattroporte’s range of navigation and entertainment systems were completely updated, comprising the New Maserati Multimedia System and the Bose® Multi Media System. Developed by Marelli, the Multimedia System includes, as standard: on-board computer, satellite navigation system (where the digital cartography is available), CD- ROM and mp3 player, Hard Disk driver, mp3 music file Jukebox, 30 GB hard disk, voice controls, Bluetooth®, and USB/AUX-in port with USB reader function. Maserati Academy 7 Maserati Range Technical Updates MY09 GranTurismo S (M145LL) The sports version of the marque’s coupe, the Maserati GranTurismo S (MI45GL) was intended for those looking for a car with a unique identity. The 4.7 litre V8 engine can generate a power of 323 kW (440 HP). The Transaxle system is used for engine and gearbox, the leading-edge of Maserati technology and a feature only used on the highest-performing cars. The suspensions maximise the Transaxle system’s potential thanks to the new fixed-setting dampers, with 10% more damping force, with revised compression and extension ratio and more rigid rear torsion bar. The braking system, developed in association with Brembo, guarantees constant, impeccable performance thanks to the Dual Cast technology. Exterior The sportscar character of the GranTurismo S is underlined by Pininfarina’s modern, aggressive line, given added prestige by unmistakable details such as the red trims on the Maserati Trident and the Saetta logo, matching the standard colour of the brake calipers, as used on Maserati racing cars. Maserati Academy 8 Maserati Range Technical Updates MY09 The GranTurismo S’s sportier nature is reflected to perfection in the new lines and new alloy wheels, dark headlamps, new aerodynamic underdoor moulding covers and a boot spoiler. Interior The seats have a central panel upholstered in Alcantara with a new design, with horizontal piping; as well as the combination of Frau® Leather and Alcantara, the seat central panels are also available in Pekary leather. Maserati Academy 9 Maserati Range Technical Updates MY09 GranTurismo S Automatic (M145HL) The GranTurismo S Automatic offers two fundamental innovations: the 4.7 litre 440 HP engine, and the automatic 6-speed transmission. The increased engine torque, especially at medium/low rpm, combined with the automatic six-speed transmission, exalts the car’s genuine GT nature. As on the GranTurismo S, the Brembo braking system with front calipers with six pistons delivers even higher performance thanks to
