The original Maserati Quattroporte (Tipo AM107) was built between 1963 and 1969. It was a large saloon car powered by V8 engines—both firsts for a series production Maserati.

History[edit]

The task of styling the Quattroporte was given to Turinese coachbuilder Pietro Frua, who drew inspiration from a special Maserati 5000 GT (chassis number 103.060) he had designed in 1962 for Prince Karim Aga Khan.[4] While the design was by Frua, body construction was carried out by Vignale.

Series I (1963–1966)[edit]

The Quattroporte was introduced at the October-November 1963 Turin Motor Show,[5] where a pre-production prototype was on the Maserati stand next to the Mistral coupé. Regular production began in 1964. The Tipo 107 Quattroporte joined two other grand tourers, the Facel Vega and the Lagonda Rapide, capable of traveling at 200 km/h (124 mph) on the new motorways in Europe. It was equipped with a 4.1-litre (4,136 cc or 252 cu in) V8 engine, producing 260 hp (194 kW; 264 PS) DIN at 5,000 rpm, and either a five-speed ZF manual transmission or a three-speed Borg Warner automatic on request. Maserati claimed a top speed of 230 km/h (143 mph). The car was also exported to the United States, where federal regulations mandated twin round headlamps in place of the single rectangular ones found on European models.

Between 1963 and 1966, 230 units were made.

Series II (1966–1969)[edit]

In 1966, Maserati revised the Tipo 107, adding the twin headlights already used on the U.S. model. A leaf-sprung solid axle took place of the previous De Dion tube. The interior was completely redesigned, including the dashboard which now had a full width wood-trimmed fascia. In 1968 alongside the 4.1-litre a 4.7-litre version became also available (AM107/4700), developing 290 PS (213 kW; 286 hp) DIN. Top speed increased to a claimed 255 km/h (158 mph),[6] making the Quattroporte 4700 the fastest four-door saloon in the world at the time.

Around 500 of the second series were made, for a total of 776 Tipo 107 Quattroportes. Production ended in 1969.[6]

Specifications[edit]

Quattroporte 4200 V8 engine

The first generation Quattroporte had a steel unibody structure, complemented by a front subframe. Front suspension was independent, with coil springs and hydraulic dampers. Rear suspension used a coil sprung De Dion tube featuring inboard brakes on the first series, later changed to a more conventional Salisbury leaf sprung solid axle with a single trailing link on the second series. On both axles there were anti-roll bars. Brakes were solid Girling discs all around. A limited slip differential was optional.

Engines[edit]

The long lived quad cam, all-aluminium Maserati V8 engine made its début on the Quattroporte. It featured two chain-driven overhead camshafts per bank, 32 angled valves, hemispherical combustion chambers, insterted cast iron wet cylinder liners, and was fed through an aluminium, water-cooled inlet manifold by four downdraught twin-choke Weber carburettors—initially 38 DCNL 5 and 40 DCNL 5 on 4200 and 4700 cars respectively, later changed to 40 DCNF 5 and 42 DCNF 5 starting from December 1968.[3]

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).[7] Carrozzeria Frua designed the car, the prototype of which was displayed in Paris 1971 and Geneva 1972.[8] 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.[9] 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.[8]

The second generation Quattroporte, named Maserati Quattroporte II (AM 123), made its world première at the October 1974 Paris Motor Show,[10] followed by an appearance at the later Turin Motor Show. As a result of Citroën's purchase of the Italian company, it was a much different car from its predecessor and its successors: built on an extended Citroën SM chassis, it featured front wheel drive and Citroën's hydropneumatic suspension and swivelling directional headlights. The car had Bertone bodywork, penned by Marcello Gandini. 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.[7]

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.[11] The bankruptcy of Citroën and Maserati ended the V8's development in 1975.[12]

Maserati made 13 Quattroporte IIs. While the prototype was built in 1974, the succeeding twelve cars were built to order between 1976 and 1978.[7] 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.[7]

The third generation Maserati Quattroporte (Tipo AM 330) was developed under the Alejandro de Tomaso-GEPI ownership. After the brief parenthesis of the Citroen-era front-wheel drive Quattroporte II, the third generation went back to the classic formula of rear-wheel drive and large Maserati V8 engine. It was designed by Giorgetto Giugiaro.

History[edit]

During 1976, Giorgetto Giugiaro presented two Italdesign show cars on Maserati platforms, called the Medici I and Medici II. The latter, based on Maserati's Kyalami coupé, had features that would make it into the production version of the third-generation Quattroporte.

Maserati Medici II

A pre-production Quattroporte was introduced to the press by Maserati president Alejandro de Tomaso on 1 November 1976,[13] in advance of its début at the Turin Motor Show later that month. It was only three years later though, in 1979, that the production version of the car went on sale.[14][15]

Initially "4porte" badging was used, changed in 1981 to Quattroporte. Two versions of the V8 engine were available: a 4,930 cc one producing 280 PS (206 kW; 276 bhp),[15] and a smaller 4,136 cc engine producing 255 PS (188 kW; 252 bhp)[15]—later 238 hp (177 kW; 241 PS)[citation needed], which was phased out in 1981. The interior was upholstered in leather and trimmed in briar wood. The Quattroporte III marked the last of the hand-built Italian cars; all exterior joints and seams were filled to give a seamless appearance. From 1987 the Royale superseded the Quattroporte.

Maserati Royale[edit]

Maserati Royale

On 14 December 1986, 60th anniversary of Maserati as a car manufacturer, De Tomaso presented in Modena the Maserati Royale, a built-to-order ultra-luxury version of the Quattroporte.[16] It adopted a higher compression 4.9-litre engine, putting out 300 PS (221 kW; 296 bhp). Besides the usual leather upholstery and veneer trim, the passenger compartment featured a revised dashboard with analogue clock, four electrically adjustable seats, retractable veneered tables in the rear doors and a mini-bar. Visually the Royale was distinguished by new disc-shaped alloy wheels and silver-coloured side sills. De Tomaso announced a limited run of 120 Royales,[16] but when production ceased in 1990 53 of them had been made.

In all, including the Royale, 2,155 Quattroporte IIIs were produced.[17]

Specifications[edit]

Interior of the third generation Quattroporte

The third generation Quattroporte used an all-steel unibody structure. The chassis was related to that of the Maserati Kyalami, in turn derived from the De Tomaso Longchamp and therefore ultimately related to the De Tomaso Deauville luxury saloon. Front suspension was of the double wishbone type, with single coaxial dampers and coil springs and an anti-roll bar. The rear axle used a peculiar layout very similar to Jaguar independent rear suspension. Each cast aluminium hub carrier was linked to the chassis only by a single lower wishbone, the half shafts doubling as upper control arms, and was sprung by twin coaxial dampers and coil springs units. Rear brakes were mounted inboard, the callipers bolted directly to the housing of the differential. The entire assembly was supported by a bushing-insulated crossbeam. Initially a Salisbury-type limited slip differential was used; in 1984 it was replaced by a more advanced Gleason-licensed Torsen—or "Sensitork" in Maserati parlance.[18]

The engine was an evolution of Maserati's own all-aluminium, four overhead cam V8, fed by four Weber carburettors. The automatic transmission initially used was a three-speed Borg–Warner automatic transmission, soon replaced by a Chrysler A727 "Torqueflite" gearbox. Manual gearboxes were ZF S5 five speeds. When leaving the factory all 4200 Maseratis were originally fitted with Pirelli Cinturato 205VR15 tyres (CN72).

Coachbuilders[edit]

Milanese coachbuilder Carrozzeria Pavesi outfitted several armoured Quattroportes during the 1980s. One of them, a 1983 Blu Sera example nicknamed Calliope, was notably used by President of the Italian Republic Sandro Pertini as official state car during his tenure.[19]

Autocostruzioni SD of 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 its introduction in 1986 was 210 million lire.[17]

The fourth generation Quattroporte (Tipo AM337) was built from 1994 to 2001. It was built on an evolved and stretched version of the Biturbo saloons' architecture, and used twin-turbocharged V6 and V8 engines respectively from the Maserati Shamal and Ghibli coupés. For this reason the car retained very compact exterior dimensions, and is smaller than any of its predecessors and successors. As the designer's signature angular rear wheel arches gave away, the wedge-shaped aerodynamic (0.31 Cd) body was the work of Marcello Gandini.

History[edit]

The world première of the fourth generation Quattroporte took place at the April 1994 Turin Motor Show[21] and the car went on sale towards the end of the year. Initially the Quattroporte was powered by twin-turbocharged, 24-valve V6 engines from the Maserati Ghibli. For export markets there was a 2.8-litre unit, producing 284 PS (209 kW; 280 hp) and reaching a claimed top speed of 255 km/h (158 mph). As local taxation strongly penalized cars over two-litre in displacement, Italian buyers were offered a 2.0 L version, which developed a little more power (287 PS or 211 kW) but less torque than the 2.8; on the home market the 2.8 was not offered until a year after its introduction.[22] The cabin was fully upholstered in Connolly leather and trimmed in elm burr veneer.

After having been displayed in December 1995 at the Bologna Motor Show,[23] in 1996 a 3.2-litre twin-turbocharged V8 Quattroporte was added to the range. Derived from the Maserati Shamal's engine, on the Quattroporte this unit developed 336 PS (247 kW; 331 hp) for a claimed top speed of 270 km/h (168 mph). At the same time some minor updates were introduced on all models: new eight-spoke alloy wheels and aerodynamic wing mirrors, and seicilindri or ottocilindri (Italian for "six-" and "eight-cylinders" and) badges on the front wings, denoting which engine was under the bonnet. As standard all three engines were mated to a Getrag 6-speed gearbox, while 4-speed automatic transmissions were available on request with the 2.8 and 3.2 engines—respectively a 4HP22 by ZF and a computer-controlled one by Australian firm BTR.

In July 1997 Ferrari acquired 50% of Maserati S.p.A. from Fiat S.p.A.. Ferrari immediately undertook a renewal of Maserati's dated production facilities, as well as made improvements to the manufacturing methods and quality control. This resulted in the improved Quattroporte Evoluzione, introduced at the March 1998 Geneva Motor Show.[24] It featured 400 all-new or modified parts out of a total 800 main components.[22] Powertrains and performance remained unvaried, save for the adoption of the same BTR trasmission from the 3.2 V8 by the automatic 2.8 V6 model. The Evoluzione no longer had the oval Maserati clock on the dashboard. Outside it was distinguished from the earlier models by details like "V6 evoluzione" or "V8 evoluzione" badges on the front wings and redesigned wing mirrors. Production of the fourth generation Quattroporte ended in May 2001.

Specifications[edit]

The Quattroporte was a four-door, five-seater saloon with a steel unibody construction. The overall layout remained unchanged from the Biturbos from which the car descended: longitudinal front engine, rear-wheel drive, all-independent suspension with MacPherson struts upfront and trailing arms at the rear. Despite these similarities the suspension had been re-engineered: rear trailing arms had a tube framework structure like on the Shamal, and together with the limited slip differential were attached to the body via a newly designed tubular subframe.

The fifth generation of the Quattroporte (Tipo M139) was unveiled to the world at the Frankfurt Motor Show on 9 September 2003[25] 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).[26]

Over 5,000 Quattroportes were built in 2006.[27]

History[edit]

2003–2008[edit]

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.[28]

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.[29] 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 295/30 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.[30]

At the 2008 NAIAS Maserati launched the Quattroporte Collezione Cento, a 100-examples limited edition.[31] 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.

2008–2012[edit]

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.

Sport GT S at Goodwood 2009

The Quattroporte Sport GT S was premièred at the North American International Auto Show in January 2009.[32] 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.[33] 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.

Specifications[edit]

The Quattroporte body is a steel unibody, with aluminium boot lid and engine bonnet; Cd is 0.35.[34] Front and rear aluminium subframes support the whole suspension and drivetrain.

A 47%/53% front/rear weight distribution[25] 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 consists of unequal length control arms with forged aluminium arms and hub carriers, coil springs and anti-roll bars on both axles.

Transmissions[edit]

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 accommodate 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 were fitted with 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-litre engines on automatic cars were converted to use a wet sump oiling system,[35] as did the later 4.7-litre, codenamed F136Y.

The current sixth-generation Quattroporte was introduced in early 2013. With a 3,171 mm (124.8 in) wheelbase it is a considerably larger vehicle than any of its predecessors, to set itself apart from the smaller Maserati Ghibli, which shares its underpinnings. Engine choice includes twin-turbocharged V6 and V8 petrol engines, as well as a turbodiesel.

History[edit]

Development[edit]

The new model was designed at a special Maserati-only department within the Fiat Group Centro Stile design centre, under the guidance of ex-Pininfarina designer Lorenzo Ramaciotti.[citation needed] Drivetrains, platform, suspension, and body elements such as the front doors[43] are common to the Quattroporte and the smaller Ghibli saloon, which sits on a 173 mm (6.8 in) shorter wheelbase. The Quattroporte is built at the Officine Maserati Grugliasco plant in Grugliasco, near Turin, dedicated to Giovanni Agnelli; this former Bertone plant was acquired by Fiat S.p.A. in 2009 and renovated for production of the two Maserati saloons.[44]

Launch[edit]

The current sixth-generation Quattroporte was revealed at the North American International Auto Show in Detroit in January 2013. Production had started in November 2012.[45] Initially the range included the V8 twin-turbo, rear-wheel drive Quattroporte GTS and the V6 twin-turbo, Quattroporte S, available with Q4 all-wheel drive and rear-wheel drive depending on the market. The flagship GTS can be distinguished from its trapezoidal instead of round tail pipes. A V6 turbodiesel model for European markets was introduced in September 2013 at the Frankfurt Motor Show.[46]

Quattroporte Zegna limited edition[edit]

After a preview as a concept car at the 2013 Frankfurt Motor Show,[46] a total of 100 Quattroporte Zegna were produced for 2014 in collaboration with Italian fashion house Ermenegildo Zegna.[47] The cars feature a platinum-metallic silk paint colour with aluminium pigments, and an interior upholstered in a special fabric which emulates that of Zegna suits.

2015[edit]

At the November 2014 Los Angeles Auto Show Maserati introduced the model year 2015 range.[48] The Quattroporte GTS received mild cosmetic updates, such as new multi-spoke forged alloy wheels, colour-matched lower bodywork, and red-accented Maserati logos, while all models were given upgraded standard equipment and ampler trim choice.[48]

Specifications[edit]

Body and chassis[edit]

The Quattroporte uses a mixed steel and aluminium unibody chassis. Front and rear crash structures, the shock towers, the front wings, all four doors, the engine bonnet and the boot lid are aluminium. Front suspension uses unequal length wishbones with a forged aluminium upright/hub carrier, and an anti-roll bar; rear suspension is a 5-link, with four aluminium links and a larger, steel fifth lower arm that also serves as spring seat. A front aluminium subframe supports the engine by two mounting points, the steering rack and the lower suspension arms. A rear subframe, made of steel, houses the differential and supports all five suspension links.

Engines and performance[edit]

The range comprises two petrol engines, a 3.8-litre 90º V8 producing 523 bhp (390 kW; 530 PS) and a 3.0-litre 60° V6 producing 404 bhp (301 kW; 410 PS), 2,979 cc (182 cu in);[49][50] both use a turbocharger per cylinder bank, twin intercoolers and are direct injection. The petrol engines are designed and assembled by Ferrari. V6 engine blocks are cast and machined to Ferrari's specifications respectively in Chrysler's Kokomo, Indiana and Trenton Engine Plant, then shipped to Modena (Italy) for assembly by Ferrari.[51] A diesel engine is also available, a 275 PS (202 kW; 271 bhp) 3.0-litre V6 with a single variable geometry turbocharger, designed and built by FCA's subsidiary VM Motori. By 2018, the Quattroporte S Q4 will be upgraded to produce 450 bhp (336 kW; 456 PS) from its V6, and the GTS to produce 560 bhp (418 kW; 568 PS) horsepower from its V8, both with all-wheel drive (for the V8 to increase performance).[52] The 2014 Quattroporte GTS accelerated from 0-60 in 4.2 seconds and ran the 1/4 mile in 12.7 seconds in Car and Driver's December, 2014 road test.[53]

Transmission[edit]

All engines are mated to a ZF-supplied 8HP70 8-speed automatic gearbox,[54] with four-wheel drive available on the V6 in left-hand drive markets only.

The V6 four-wheel drive Q4 drivetrain is the same as that in the Ghibli.[55] Attached to the end of the 8-speed transmission is a transfer case, containing an electronically controlled multi-plate wet clutch, which sends power trough a drive shaft to an open differential bolted to the oil pan. During normal operation the car is rear-wheel drive only; when needed the system can divert up of 50% of engine torque to the front wheels.[56]
