As Maserati's sales increased, Prince Karim Aga Khan ordered a special Maserati 5000 WP, chassis number 103,060, designed by Pietro Frua. The following year, Maserati showed the first-generation Quattroporte of 1963, which bore a resemblance to an earlier drawing. While the design was by Frua, construction was carried out by Vignale.
It was equipped with a 4.1-litre (4,136 cc/252 cuin) V8 engine, producing 256 hp (191 kW; 260 PS) SAE at 5,600 rpm, and either a five-speed ZF manual transmission or a three-speed automatic. Maserati claimed a top speed of 230 km/h (143 mph).
Between 1963 and 1966, 230 units were made.
In 1966, Maserati revised the Tipo 107, adding the twin headlights already used on the U.S. model) and, from 1968, included a 4.7-litre, 295 hp (220 kW; 299 PS)(SAE) engine. Top speed increased to a claimed 255 km/h (160 mph), making it the fastest four-door sedan in the world at the time. Around 500 of the second series were made, for a total of 776 Tipo 107 Quattroportes. Production stopped in 1969.
Special models 1971 and 1974
In 1971, Karim Aga Khan ordered another special on the Maserati Indy platform. Rory Brown was the chief engineer. It received the 4.9-litre V8 engine (Tipo 107/49), producing 300 PS (221 kW). Carrozzeria Frua designed the car, the prototype of which was displayed in Paris 1971 and Geneva 1972. The car was production ready, even receiving its own chassis code (AM 121), but Citroën used their influence to have Maserati develop the SM-based Quattroporte II instead. Only two vehicles were finished, chassis #004 was sold by Maserati to the Aga Khan in 1974, and the prototype #002 went to the King of Spain, who bought his directly from Frua.
Quattroporte II (AM123, 1974–1978)
|Designer||Marcello Gandini at Bertone|
|Body and chassis|
|Engine||3.0 L Tipo AM 114.56.30 DOHC V6|
In 1974, Maserati presented the Quattroporte II (AM 123) at the Turin Show on an extended Citroën SM chassis. This was the result of Citroën's purchase of the Italian company. The car had Bertone bodywork, penned by Marcello Gandini, and was the only Maserati Quattroporte to feature hydropneumatic suspension and front wheel drive. It also had the swivelling directional headlights like the SM/DS. The 1973 oil crisis combined with the collapse of the Citroën/Maserati relationship, made Maserati unable to gain EEC approval for the car. Most of the cars built were sold in the Middle East and in Spain, where such type approval was not necessary.
The front-wheel drive layout and the modest V6 3.0-litre powerplant based on the Citroën SM engine did not attract customers. Its 210 PS (154 kW) at 5,500 rpm was barely enough to propel the 1,600 kg (3,527 lb) car to 200 km/h (124 mph).
In 1974, Citroën had Maserati develop a V8 engine. An SM was used to test this 260 PS (191 kW) engine - the adjustments needed were modest and transformed the SM into a sports car. The bankruptcy of Citroën and Maserati ended the V8's development in 1975.
Maserati made 13 Quattroporte IIs. While the prototype was built in 1974, the succeeding twelve cars were built to order between 1976 and 1978. The nearly stillborn Quattroporte II project was costly for the small company, and the firm reached four billion lire in debt by the end of 1978.

Considered a "businessman's Maserati," the Quattroporte III was presented by newly empowered Maserati chief Alejandro de Tomaso and his design staff in 1977. This was a rear wheel drive car, powered by a large V8 engine. It was important to de Tomaso that there be an Italian vehicle to compete with the recently launched Mercedes-Benz 450SEL 6.9. The Quattroporte III marked the last of the hand-built Italian cars. All exterior joints and seams were filled to give a seamless appearance.
In 1976, Giorgetto Giugiaro presented two ItalDesign show cars on Maserati platforms, called the Medici I and Medici II. The latter had features that would make it into the production of the third-generation Quattroporte. At the 1977 Turin Motor Show, Maserati announced the Quattroporte III (Tipo AM 330), which took much from the Medici show cars, based on Maserati's Kyalami coupé, which in turn was based on the De Tomaso Longchamp. Styling emphasis was placed on linearity, which was also useful to reduce tooling cost.
The Quattroporte III went into production in 1979, equipped with a 4,136 cc V8 engine (referred to as the "4200" by Maserati) producing 255 hp (190 kW; 259 PS), later 238 hp (177 kW; 241 PS) (SAE). Also available was a 4.9-litre V8 producing 280 hp (209 kW; 284 PS) at 5,800 rpm). A distinguishing characteristic of the vehicle was its interior. The automatics initially used a three-speed Borg–Warner automatic transmission, soon replaced by a Chrysler Torqueflite gearbox. Manual gearboxes were ZF-built five-speeds. The smaller engine was phased out in 1985. When leaving the factory all "4200" Maseratis were originally fitted with Pirelli Cinturato 205VR15 tyres (CN72).
From 1979 up to 1981 "4porte" badging was used, changed to Quattroporte for up to 1989. In 1986, the Maserati Royale, a handbuilt to order ultra-luxury version of the Quattroporte III, appeared. The engine was upgraded to 295 hp (220 kW; 299 PS) (SAE).
In all, 2,155 Quattroporte IIIs were produced, including one for Italian presidential use and 53 of them being Royales. Production ceased in 1990.
Turinese coachbuilder Salvatore Diomante also offered a 65 cm longer limousine version, fully equipped with white leather, "abundant burr walnut", mini-bar, video recorder and many other necessities. The price of the Diomante limousine at introduction (1986) was 210 million lire.

The Quattroporte IV (Tipo 337) from 1994 was a restyled, four-door version of the Ghibli II coupe. It was designed by Marcello Gandini. The new car was smaller than its predecessors, aerodynamic (0.31 Cd), and featured Gandini's trademark angular rear wheel arch.
A 2.8-litre twin turbo V6 was installed, producing 284 PS (209 kW; 280 hp), reaching a claimed top speed of 255 km/h (158 mph). Italian buyers had an optional "tax special" 2-litre version producing 287 PS (211 kW; 283 hp). Both engines came from the Maserati Biturbo. The 2.8 was not even offered in the home market until a year after its introduction. In 1995, the V8 3.2-litre Biturbo from the Maserati Shamal was introduced, developing 335 PS (246 kW; 330 hp) with a claimed top speed of 270 km/h (168 mph).
After Ferrari took over Maserati in July 1997, it introduced a Quattroporte Evoluzione for 1998. It featured 400 new or improved parts out of a total 800, as well as made improvements to Maserati's manufacturing methods. The Evoluzione no longer had the oval Maserati clock on the dashboard. Production ended in May 2001.

The fifth generation of the Quattroporte (Tipo M139) was unveiled to the world at the Frankfurt Motor Show on 9 September 2003 and made its U.S. première at the 2003 Pebble Beach Concours d'Élégance; production started in 2004. Exterior and interior design was done by Pininfarina. Built on an entirely new platform, it was 50 cm (19.7 in) longer than its predecessor and sat on a longer 40 cm (15.7 in) wheelbase. The same architecture would later underpin the GranTurismo and GranCabrio coupés and convertibles. Initially it was powered by an evolution of the naturally aspirated dry sump 4.2-litre V8 engine, mounted on the Maserati Coupé, with an improved output of 400 PS (294 kW). Due to its greater weight compared to the Coupé and Spyder, the 0-62 mph (0–100 km/h) time for the Quattroporte was 5.2 seconds and the top speed 171 mph (275 km/h).
Over 5,000 Quattroportes were built in 2006.
The Maserati Quattroporte was initially offered in only one configuration, equipped with the DuoSelect transmission. The base Quattroporte DuoSelect was recognizable by its chromed grille with horizontal slats; adaptive Skyhook suspension and 330 mm brake disks with four piston callipers all-around were standard. Maserati put emphasis on personalization, offering customers a choice of fifteen exterior paint colours, Poltrona Frau leather upholstery in ten hues, contrasting seat piping and stitching and three types of wood inserts. At the Frankfurt Motor Show in September 2005 Maserati introduced the Executive GT and Sport GT trim levels.
The Quattroporte Executive GT was a comfort- and luxury-oriented specification; it came equipped with wood-rimmed steering wheel, an alcantara suede interior roof lining, ventilated, adaptive, massaging rear seats, rear air conditioning controls, veneered retractable rear tables, and curtain shades on the rear windows. The exterior was distinguished by 19 inch eight-spoke ball-polished wheels and chrome mesh front and side grilles.
The Quattroporte Sport GT variant offered several performance upgrades: faster shifting transmission and firmer Skyhook suspensions thanks to new software calibrations, seven-spoke 20 inch wheels with low-profile tyres, cross-drilled brake rotors and braided brake lines. Model-specific exterior trim included dark mesh front and side grilles and red accents to the Trident badges, as on vintage racing Maseratis. Inside there were aluminium pedals, a sport steering wheel and carbon fibre in place of the standard wood inserts.
A new automatic transmission was presented at the Detroit Motor Show in January 2007, with the first cars delivered right after the launch, marketed as Maserati Quattroporte Automatica. As all three trim levels were offered in both DuoSelect and Automatica versions, the lineup grew to six models.
The Quattroporte Sport GT S was introduced at the Frankfurt Motor Show in September 2007. Taking further the Sport GT's focus on handling, this version employed Bilstein single-rate dampers in place of the Skyhook adaptive system. Other changes from the Sport GT comprised a lowered ride height and 10 mm wider 195/30 rear tyres, front Brembo iron/aluminium dual-cast brake rotors and red-painted six piston callipers. The cabin was upholstered in mixed alcantara and leather, with carbon fibre accents; outside the door handles were painted in body colour, while the exterior trim, the 20 inch wheels and the exhaust pipes were finished in a "dark chrome" shade.
At the 2008 NAIAS Maserati launched the Quattroporte Collezione Cento, a 100-examples limited edition. Its unique specification featured an ivory paint colour with a waist coachline, matched to Cuoio tan tufted leather upholstery and Wengé trim inlaid with mother of pearl. Standard equipment comprised most of the available infotainment optionals.
Images of the facelifted Quattroporte appeared on the Internet on 30 January 2008; the car made its official début at the 2008 Geneva Motor Show. Overseen by Pininfarina, the facelift brought redesigned bumpers, side sills and side mirrors, a convex front grille with vertical bars instead of horizontal, new headlights and tail lights with directional bi-xenon main beams and LED turn signals. Inside there was a new navigation and entertainment system. All Quattroporte models now used the ZF automatic transmission, the DuoSelect being discontinued.
The 4.2-litre Quattroporte now came equipped with single-rate damping comfort-tuned suspension and 18 inch wheels. Debuting alongside it was the Quattroporte S, powered by a wet-sump 4.7-litre V8, the same engine of the Maserati GranTurismo S, with a maximum power of 430 PS (316 kW; 424 hp) and maximum torque of 490 N·m (361 lb·ft). In conjunction with the engine, the braking system was upgraded to cross-drilled discs on both axles and dual-cast 360 mm rotors with six piston callipers at the front. Skyhook active damping suspension and 19 inch V-spoke wheels were standard. Trim differences from the 4.2-litre cars were limited to a chrome instead of titanium-coloured front grille. Production of the restyled vehicle started in June 2008 as Model Year 2009.
The Quattroporte Sport GT S was premièred at the North American International Auto Show in January 2009. Its 4.7-litre V8 produced 440 PS (324 kW; 434 hp), ten more than the Quattroporte S, thanks to revised intake and to a sport exhaust system with electronically actuated bypass valves. Other mechanical changes were to the suspensions, where as on the first Sport GT S single-rate dampers took place of the Skyhook system, ride height was further lowered and stiffer springs were adopted. The exterior was distinguished by a specific front grille with convex vertical bars, black headlight bezels, red accents to the Trident badges, the absence of chrome window trim, body colour door handles and black double oval exhaust pipes instead of the four round ones found on other Quattroporte models. Inside veneers were replaced by "Titan Tex" composite material and the cabin was upholstered in mixed Alcantara and leather.
A special edition GT S was introduced at the 2010 Geneva Motor Show: the Quattroporte Sport GT S Awards Edition, celebrating the 56 awards received by the sixth generation Quattroporte during its career. Its unique specification comprised "Nero pianoforte" or specially-developed pale gold "Quarzo fuso" pearlescent paint, satin grey wheels, polished brake callipers and all chrome trim in a dark finish.
A 47%/53% front/rear weight distribution was achieved by setting the engine behind the front axle, inside the wheelbase (front-mid-engine layout) and the adoption of a transaxle layout. With the later automatic transmission - fitted in the conventional position in block with the engine - weight distribution changed to 49%/51% front/rear. The suspension system consisted of unequal length control arms with forged aluminium arms and hub carriers, coil springs and anti-roll bars on both axles.
The DuoSelect electro-actuated transmission available at the launch of the fifth generation Quattroporte was a development of the CambioCorsa unit first used in the Maserati Coupé. It was a Ferrari-based semi-automatic transmission, mounted at the rear axle in block with the differential in a transaxle layout, with the twin-plate dry clutch located in a bell housing attached to the rear of the engine. A torque tube joined rigidly together the two units. Gear shifting was done via the standard paddle shifters behind the steering wheel; there was no gear lever on the centre tunnel, but rather a small T-shaped handle used to quickly engage first gear and reverse when manoeuvring at slow speed.
The 6-speed torque converter automatic transmission was a 6HP26 supplied by ZF Friedrichshafen. Unlike the DuoSelect it was placed in the conventional position right behind the engine; to accomodate it and the new rear differential the front and rear subframes as well as part of the transmission tunnel had to be redesigned. Manual shifting was possible by the centre-console mounted gear lever; in addition Sport GT cars came equipped with paddle shifters as standard, while on other models they were an optional extra.
All Quattroporte models mounted a limited slip differential.
The V8 engines of the fifth generation Quattroporte belonged to the "Ferrari-Maserati F136" family; they had aluminium-silicon alloy block and heads, a crossplane crankshaft, four valves per cylinder driven by two overhead camshafts per bank and continuous variable valve timing on the intake side. F136S 4.2-litre engines in DuoSelect equipped cars used a dry sump lubrication system; F136UC 4.2 engines on automatic cars were converted to use a wet sump sump oiling system, as did the later 4.7-litre, codenamed F136Y.

Bellagio Fastback Touring
In 2008, at the Concorso d'Eleganza Villa d'Este, Milanese coachbuilder Carrozzeria Touring Superleggera unveiled the Maserati Bellagio Fastback Touring, a 5-door station wagon built on the basis of the fifth generation Quattroporte. In May 2013 a Bellagio Fastback was auctioned by RM Auctions at their Villa Erba event, in occasion of Concorso d'Eleganza Villa d'Este; the price was 117,600 €. According to the auction house, four examples have been built by Carrozzeria Touring.
In 2009 Swiss Team announced the development of "Maserati Quattroporte EVO" International Superstars Series racing cars based on the 4.2-litre Quattroporte M139, to be piloted by Andrea Chiesa. Swiss Team fielded the cars in the 2009, 2010, 2011 and 2012 seasons; Italian racing driver Andrea Bertolini won the 2011 championship at the wheel of a Swiss Team Quattroporte.

The new sixth-generation Quattroporte was revealed at the North American International Auto Show in Detroit in January 2013. Production started in November 2012. The new model was designed by a Maserati-only department within the Fiat Group Centro Stile design centre, under the guidance of ex-Pininfarina designer Lorenzo Ramaciotti. It is built at the old Bertone plant, on the outskirts of Turin.
The vehicle is designed with many elements that will be common to the Quattroporte, a new Ghibli model, and for the SUV Levante model planned for 2014. It is however considerably larger than the previous generation to set itself apart from the Ghibli slotted below in the Maserati line-up.
The Quattroporte features new Ferrari-built V6 and V8 engines; the initial engines being a petrol 3.8-litre (3,798 cc) V8 producing 523 bhp (390 kW; 530 PS) and a 3.0-litre V6 producing 404 bhp (301 kW; 410 PS). It is be mated to a ZF-supplied 8-speed automatic gearbox, with four-wheel drive available on the V6 in left-hand drive markets only.
A total of 100 Quattroporte were produced for 2014 in collaboration with Ermenegildo Zegna. The cars features a special effect platinum-metallic silk paint colour with aluminum pigments along with a new interior fabric that emulates the Zegna clothing line.
