Maserati GranTurismo

The history of the automobile is punctuated by models that transcend their transport function to become cultural icons and pillars of a brand's identity. The Maserati GranTurismo is, undeniably, one of these milestones. This report is dedicated to dissecting the trajectory of this coupe which, over two distinct generations, not only saved Maserati from an identity crisis but redefined the luxury Grand Tourer (GT) segment. The analysis presented here is not limited to a chronology of launches; it investigates the engineering decisions, design nuances, and market strategies that shaped the model, with a particular focus on its reception and commercialization in the Brazilian market.

The "Gran Turismo" concept is foundational to the House of the Trident. Maserati claims the invention of this category with the launch of the A6 1500 GT Pininfarina in 1947. The philosophy was revolutionary for the time, but deceptively simple: take a sophisticated racing engine and install it in a seductive, luxurious body comfortable enough for continental travel. Seventy years later, the launch of the modern GranTurismo in 2007 (code M145) and its reinvention in 2023 (code M189) continue to strictly follow this dogma, balancing the dichotomy between track performance and cruising comfort.

To understand the importance of the GranTurismo, it is necessary to situate it in the corporate context of the mid-2000s. Maserati, then under the operational control of Ferrari (within the Fiat Group), desperately needed a successor for the Maserati Coupé (known as the 4200 GT) and the Spyder. The original replacement project became complex and expensive, eventually being transferred to its sister brand and launched as the Ferrari California. This left Maserati in a dangerous vacuum, without a flagship coupe. The response was the lightning-fast development of the GranTurismo M145, which went from design to production in just nine months — an industry record that reflects the urgency and competence of Italian engineering.

The first generation of the GranTurismo is one of the longest-lived in the history of modern sports cars, remaining in production for 12 years. Its persistence in the market was not just a sign of budget constraints from FCA (Fiat Chrysler Automobiles), but a testament to the timelessness of its design and the charisma of its mechanical assembly.

Design and Aesthetics: Pininfarina's Masterpiece

The design of the GranTurismo M145 was entrusted to the Pininfarina studio, under the creative direction of American designer Jason Castriota. The instruction was clear: create a true four-seater (a real 2+2, capable of accommodating four adults comfortably), distinguishing itself from rivals like the Porsche 911 or the Jaguar XK, which offered merely symbolic rear seats.

The visual result was a masterclass in proportion. The car was large — 4,881 mm in length and a 2,942 mm wheelbase — but the lines camouflaged its mass. The front was dominated by an aggressive oval grille with the concave trident, a direct reference to the racing cars of the 1950s. The side silhouette flowed organically, with a beltline that rose over the rear wheels to create muscular "shoulders," evoking power and stability.

A crucial design detail was the influence of the "Birdcage 75th" concept car. The fluidity of the front fender lines and the way the hood dove toward the grille were elements inherited directly from this concept, giving the GranTurismo an elegance that has aged gracefully, resisting ephemeral automotive design trends.

Mechanical Engineering: Chassis and Suspension

Built on the M139 platform (a shortened evolution of the Quattroporte V sedan's platform), the GranTurismo utilized a steel unibody structure. Although heavier than the aluminum structures used by Ferrari or Audi, the steel offered the necessary torsional rigidity for the comfort of a GT and passive safety.

Weight distribution was a point of obsession for the engineers. To combat the understeer tendency typical of front-engine cars, Maserati pushed the V8 engine behind the front axle, configuring a "front-mid engine" layout.

• Initial Distribution: In versions with a conventional automatic transmission, the distribution was 49% on the front axle and 51% on the rear.
• Transaxle Layout: In the sportier versions (initial S and MC Stradale), the gearbox was moved to the rear axle, integrated with the differential. This altered the distribution to 47% in the front and 53% in the back, a balance typically associated with mid-rear engine cars, ensuring exceptional traction exiting corners.

The suspension utilized double wishbones on all four wheels, with an "anti-dive" system in the front and an "anti-squat" system in the rear, ensuring the body remained level under heavy acceleration and braking. The Skyhook adaptive damping system, standard on many versions and optional on others, used sensors to continuously adjust the stiffness of the shock absorbers, prioritizing comfort in normal mode and stiffness in Sport mode.

The Heart of the Legend: The F136 Engine Family

The defining element of the GranTurismo M145 experience was the naturally aspirated V8 engine of the F136 family, jointly developed by Ferrari and Maserati and produced at the Ferrari factory in Maranello.

Unlike the F136 engines used by Ferrari (such as in the F430 and 458), which utilized a flat-plane crank to reach stratospheric RPMs and maximum power at the expense of low-end torque, Maserati opted for a cross-plane crank.

Why a Cross-Plane Crank?

This engineering choice was fundamental to the car's character. The cross-plane crank generates an uneven firing interval between the cylinder banks, resulting in two main characteristics:

• Reduced Secondary Vibration: Making the engine smoother and more luxurious for long trips.
• Sound Signature: The sound produced is bass-heavy, deep, and guttural at low revs, transforming into a mechanical howl at high revs. It is widely considered one of the best production engine sounds in history.

There were two main variants of this engine over the model's life:

• F136 U (4.2 Liters): 4,244 cc, dry sump, delivering 405 hp and 460 Nm.
• F136 Y (4.7 Liters): 4,691 cc, wet sump (in some versions) or dry sump, delivering between 440 hp and 460 hp depending on the specification.

The "simplicity" of the GranTurismo lineup is deceptive. Over 12 years, Maserati launched multiple variants, each with distinct technical specifications that significantly altered the car's behavior. Below, we detail each iteration.

GranTurismo "Base" (2007 – 2019)

Launched at the 2007 Geneva Motor Show, the inaugural model focused on comfort.

• Engine: 4.2L V8 (405 hp).
• Transmission: 6-speed ZF 6HP26 automatic (torque converter), mounted in the front, next to the engine.
• Performance: 0-100 km/h in 5.2 seconds; top speed of 285 km/h.
• Profile: It was a highway cruiser. The suspension was soft, and the gearbox response prioritized smoothness.

GranTurismo S (2008 – 2012)

The response to critics who asked for more sportiness arrived just a year later.

• Engine: Debut of the 4.7L V8 with 440 hp (324 kW) at 7,000 rpm and 490 Nm of torque.
• Transmission (The Big Difference): The "S" introduced the single-clutch automated manual gearbox "MC-Shift" (Maserati Corse Shift), mounted at the rear (transaxle).
• Technical Insight: This gearbox was brutal. In "MC Race" mode, it shifted gears in 100 milliseconds. However, in slow urban traffic, it was known to be clunky and prematurely wear out the clutch if not operated correctly.
• Visuals: 20-inch wheels, side skirts, trunk lid with integrated spoiler, and dual oval exhaust tips.
• Exhaust System: Introduction of pneumatic bypass valves in the exhaust. Below 3,000 rpm, it was quiet; above that (or when pressing the Sport button), it was direct and deafening.

GranTurismo S Automatic (2009 – 2012)

Maserati noticed a gap: customers who wanted the power of the 4.7 engine but rejected the harshness of the MC-Shift robotized gearbox.

• Configuration: Paired the 4.7 V8 engine (440 hp) with the smooth ZF automatic transmission from the 4.2 model.
• Compromise: The transmission returned to the front of the car, altering the weight distribution to 49/51. The engine was slightly remapped to offer more low-end torque, favoring urban driving. This version quickly became the best-selling of the global lineup.

GranTurismo MC (2009 – 2010) and MC Sport Line

Before the Stradale, Maserati launched limited versions and trim packages focused on the track. The initial "MC" (Maserati Corse) was a limited series based on the GT4 race car. The "MC Sport Line" package became available in 2009, allowing GranTurismo S owners to add carbon fiber parts, stiffer suspension, and racing aesthetic details to their road cars.

GranTurismo MC Stradale (2011 – 2017)

The pinnacle of the M145 platform. The MC Stradale was not just an aesthetic package; it was a performance-focused re-engineering, inspired directly by the Trofeo Maserati cars.

• Aerodynamics: The car generated real downforce at high speed, something rare for the segment at the time, thanks to a new front bumper, a hood with heat extractors, and a functional rear diffuser.
• Weight Reduction (Phase 1 - 2 Seater): The first batch (2011-2013) was strictly a two-seater. The removal of the rear seat, combined with the use of carbon fiber front seats, Brembo carbon-ceramic brakes (standard), and reduced acoustic insulation, cut 110 kg off the total weight compared to the GranTurismo S.
• Engine and Gearbox: The 4.7 V8 was tuned to 450 hp (later 460 hp). The transmission was exclusively the MC Race Shift, now capable of shifts in 60 milliseconds. It was the first Maserati to have a dedicated "Race" mode on the dashboard.
• Phase 2 (4 Seater): From 2013 to 2017, Maserati reintroduced the rear seat to the MC Stradale, answering requests from customers who wanted the performance but needed the practicality. The car maintained the aggressive look and the 460 hp engine, but the weight increased slightly.

GranTurismo Sport (2012 – 2019)

Direct replacement for the GranTurismo S in the mid-life facelift.

• Evolution: Adopted the 460 hp and 520 Nm engine from the MC Stradale.
• Aesthetics: New front bumper with larger side air intakes (to improve brake cooling) and new headlights with LED daytime running lights (DRL).
• Interior: New seats with integrated headrests and a flat-bottom steering wheel.

GranTurismo Zéda (2019)

To mark the end of production in December 2019, Maserati presented the final chassis as a unique piece of art: the GranTurismo Zéda. The tri-color paint (Blue, Black, and White) symbolized the transition: blue represented the electric future, black modern technology, and white the "raw" state of the bodywork before painting, honoring the manual industrial process of Modena.

An analysis of the production numbers reveals the model's commercial success, especially considering its price and niche. All models were manufactured at the historic Viale Ciro Menotti factory in Modena.

Detailed Production of the MC Stradale

Thanks to internal Maserati data leaks, we have a rare breakdown of the most collectible version, the MC Stradale.

Source:. Insight: With fewer than 1,000 units produced globally, the MC Stradale is significantly rarer than "Special" Ferrari models like the 458 Speciale, suggesting high potential for future appreciation.

After a three-year hiatus (2020–2022) — a period during which the Modena factory was renovated for the new era — the GranTurismo returned. The challenge of the second generation (M189) was monumental: replace the charismatic V8 without losing the soul of the brand, and integrate total electrification without compromising driving dynamics.

Architecture and "Giorgio Sport" Platform

The new GranTurismo uses a radical evolution of the Giorgio platform (famous for the Alfa Romeo Giulia). Maserati calls it a "multi-energy" architecture. The great innovation here is modularity: the chassis was designed from the ground up to accommodate both the V6 combustion engine and the electric powertrain and batteries, without altering the external dimensions or the body sheet metal. The extensive use of aluminum and magnesium kept the weight under control, despite the increase in onboard technology (~1,795 kg for the combustion versions).

The Nettuno Engine: F1 for the Streets

The centerpiece of the combustion version is the Nettuno engine, a 90-degree 3.0L twin-turbo V6. This engine represents Maserati's independence from Ferrari, being designed and built in-house in Modena.

Pre-Chamber Technology (Maserati Twin Combustion - MTC):

The Nettuno incorporates a technology derived directly from Formula 1, unprecedented in mass-production cars at this level:

• The Pre-Chamber: There is a small copper combustion chamber located above the main cylinder.
• Dual Ignition: The engine has two spark plugs per cylinder. The main spark plug ignites the mixture inside the pre-chamber.
• Fire Jets: The explosion in the pre-chamber is forced through microscopic holes into the main cylinder, creating turbulent jets of flame that burn the fuel in record time and uniformly.
• Lateral Spark Plug: A second spark plug operates in the main cylinder to ensure combustion at low loads (quiet urban use) when the pre-chamber is not efficient.

The result is an engine with very high specific output (>200 hp/liter) and superior thermal efficiency, allowing 550 hp from just 3 liters of displacement, surpassing the power of the old naturally aspirated 4.7L V8 with much more torque available at low revs.

M189 Design: The "Cofango" Concept

Under the leadership of Klaus Busse, Maserati opted for evolution, not revolution. The classic proportions were maintained, but "cleaned up".

• Cofango: A technical neologism that combines cofano (hood) and parafango (fender). The front hood is a single, gigantic, and complex-to-stamp piece that integrates the side fenders. This eliminates the visual cutlines on the front of the car, creating an uninterrupted and sculptural surface.
• Vertical Headlights: Inspired by the MC20 supercar, they confer a more technical and modern visual identity.

The M189 lineup is divided into three distinct personalities: Modena, Trofeo, and Folgore.

GranTurismo Modena

The entry-level version, focused on classic "Grand Touring".

• Engine: 3.0 V6 Nettuno.
• Power: 490 hp (360 kW) and 600 Nm of torque.
• Drive: All-Wheel Drive (AWD) standard, but with a rearward bias.
• Differential: Mechanical limited-slip.
• Performance: 0-100 km/h in 3.9 seconds. Top speed of 302 km/h.
• Character: The air suspension calibration is more geared towards comfort, and the visual is less aggressive, with discreet chrome or black details.

GranTurismo Trofeo

The high-performance combustion version.

• Engine: 3.0 V6 Nettuno with aggressive calibration.
• Power: 550 hp (405 kW) and 650 Nm of torque.
• Differential: Electronic (eLSD), allowing active torque vectoring between the rear wheels for more precise cornering.
• Performance: 0-100 km/h in 3.5 seconds. Top speed of 320 km/h.
• Corsa Mode: Exclusive to the Trofeo (and Folgore), stiffens the suspension, permanently opens the exhaust valves, and reduces traction control intervention.

GranTurismo Folgore: The Electric Lightning

The Folgore is the most powerful and revolutionary version. Maserati made the bold decision not to make a "skateboard" chassis (batteries on the floor) like Tesla or Porsche Taycan, as this would raise the driver's position.

Exclusive Folgore Engineering:

• T-Bone Battery: The battery modules (92.5 kWh gross / 83 kWh usable) are arranged in a central tunnel and behind the rear seats, forming a "T". This allows the driver to sit as low as in the gasoline model (H-point unaltered) and keeps the center of gravity on the car's roll axis.
• Motors: Three permanent magnet motors of 300 kW each (one in front, two in back).
• Real Power: Although the theoretical sum of the motors is 900 kW (1,200 hp), the battery limits the peak discharge to 761 hp (560 kW) and a monstrous 1,350 Nm of torque.
• 800V Architecture: Enables ultra-fast charging. On 350 kW chargers, the Folgore accepts up to 270 kW, recovering 100 km of range in just 5 minutes.
• Torque Vectoring: Since there are two independent motors in the rear (with no mechanical connection between the wheels), the car can apply positive torque to one wheel and negative (regeneration) to the other simultaneously, making the car "pivot" around its own axis in tight corners.

Brazil has always been a key market for Maserati in Latin America, managed by the official importer Via Italia. The GranTurismo played a fundamental role in building the brand's image in the country.

Launch History and Prices in Brazil

• 2009 (The Arrival): The GranTurismo arrived in Brazil with great fanfare. The initial price for the 4.2 version was R$ 760,000, competing directly with the Porsche 911 Carrera S and the Jaguar XKR. Via Italia brought an initial batch of 30 units, which were quickly sold. 2011/2012 (The Price Peak): With the launch of the GranTurismo MC Stradale, the price positioning rose. The model was launched at R$ 920,000, dangerously approaching the psychological barrier of 1 million reais at the time, territory then occupied by the Ferrari California and Lamborghini Gallardo.
• 2024/2025 (The New Era): The new M189 generation arrived in Brazil in a different economic scenario. With the appreciated dollar and onboard technology, prices for the new GranTurismo Trofeo start from levels above R$ 2,400,000 (estimate based on direct conversion and current import taxes for the exotic segment, and specialized dealership ads), with units configured via the Fuoriserie program easily surpassing that mark.

Brazilian Consumer Profile

In Brazil, the GranTurismo has always attracted a distinct customer profile from the Ferrari buyer. While the Ferrari is often a weekend or collection car, the GranTurismo is used by many Brazilian owners as a more frequent car, due to its ability to handle uneven asphalt (especially with the Skyhook suspension in normal mode) and the real space to take children to school or couples of friends to dinner, something impossible in a mid-engine supercar.

Used Market

The first-generation GranTurismo (M145) suffered the typical depreciation of Italian luxury cars in Brazil, but it stabilized. Today, it is seen as an "accessible" gateway into the exotic world. 2008-2010 models orbit the range of R$ 380,000 to R$ 500,000, while the MC Stradale models and newer Sport models (2015+) maintain significantly higher values, frequently above R$ 700,000 to R$ 900,000, depending on provenance and maintenance history. The maintenance of the phase variator and the clutch (on automated models) are the critical points observed by national buyers.

The table below summarizes the radical evolution between the generations, comparing the top versions of each era.

Cross-referenced technical data sources:.

The Maserati GranTurismo is a case study on how a brand can maintain its soul while navigating corporate storms and technological shifts.

The First Generation (M145) will forever be remembered as the last bastion of the "old guard": analog design, a large-displacement naturally aspirated engine, and a soundtrack that defined an era. For collectors, the MC Stradale represents the purest point of this lineage.

The Second Generation (M189) proves that Maserati is not stuck in the past. The adoption of the Nettuno engine demonstrates technical competence independent of Ferrari, while the Folgore places the brand at the technological forefront of electric GTs, offering an engineering solution (T-battery and 800V) that preserves sporty driving dynamics where others have failed.

For the Brazilian and global market, the GranTurismo remains unique. It occupies a solitary space between the excessive comfort of a Bentley Continental GT and the rigid aggressiveness of a Porsche 911 Turbo. It is a car for those who understand that the journey matters as much as the destination. With production now consolidated in Modena and the platform ready for the electric future, the GranTurismo name seems guaranteed for more decades as the supreme ambassador of Italian style and performance.
