Maserati Quattroporte Sport GT Review: Italian Grand Touring

The Maserati Quattroporte Sport GT stands as a testament to the brand’s heritage of crafting vehicles that fuse breathtaking performance with unparalleled elegance. Introduced as an elevated variant of the iconic Quattroporte lineup, this model targets enthusiasts seeking a luxury sedan that doesn’t compromise on sporting credentials. With enhancements in suspension, braking, and transmission, it transforms the already impressive base model into a dynamic force on both open roads and winding circuits.

Engineering Excellence Under the Hood

At the heart of the Quattroporte Sport GT lies a naturally aspirated 4.2-liter V8 engine, delivering 400 horsepower that propels this grand tourer with authoritative thrust. Ferrari’s influence is evident, as the powerplant shares DNA with those found in the Prancing Horse’s lineup, ensuring high-revving character and a distinctive wail that echoes through the exhaust system. Tweaks to the exhaust mapping amplify the auditory drama, providing a more aggressive tone that intensifies under hard acceleration.

Power output translates to a 0-62 mph sprint in approximately 5.2 seconds, competitive for its era among large luxury sedans, though rivals like the Porsche Panamera edged ahead in straight-line benchmarks. Top speed exceeds 167 mph, limited electronically for safety, allowing the car to stretch its legs on unrestricted autobahns. The rear-wheel-drive layout, combined with a near-perfect 49/51 weight distribution—achieved by positioning the engine behind the front axle—creates a balanced chassis primed for agile responses.

This table highlights how the Sport GT refines rather than revolutionizes raw specs, focusing on usability and driver engagement.

Transmission and Drivetrain Innovations

One of the most significant upgrades is the re-engineered paddleshift transmission, which swaps cogs 35% faster than the standard model’s often-criticized unit. In manual sport mode, shifts are crisp and responsive, banishing the jerkiness that plagued earlier automated manuals. For later iterations like the GT S, Maserati adopted a ZF six-speed automatic, tuned for quicker rev-matched downshifts and manual override that holds gears to the 7,200 rpm redline.

• Manual mode prevents upshifts at redline unless paddled.
• Automatic mode offers smooth progression for grand touring comfort.
• Exhaust bypass valve enhances the V8’s roar in sport settings.

This setup pairs seamlessly with the high-revving engine, making gear changes feel intuitive and exhilarating, whether navigating city traffic or attacking mountain passes.

Chassis Dynamics and Handling Prowess

The Sport GT’s suspension receives uprated components, including stiffer Bilstein dampers that prioritize compliance without sacrificing control. This single-rate system outperforms the adaptive Skyhook setup in ride quality, absorbing imperfections while maintaining poise during aggressive cornering. Brakes are enlarged for confident stopping power, essential for a car capable of such velocities.

Handling is where the Quattroporte Sport GT truly shines. The front-mid-engine layout imparts electric turn-in and predictable balance, eschewing snap oversteer or understeer for neutrality that invites exploitation. Steering provides ample feedback, allowing drivers to place the car with precision on sweeping bends. Reviewers praised its lithe feel, defying expectations for a large sedan weighing over two tons.

“The GT S clings to the road and has a predictable balance as the limit approaches… a confidence-inspiring neutrality.”Car and Driver

Luxury and Interior Refinement

Step inside, and the cabin envelops occupants in supple leather and Alcantara accents, with carbon-fiber-like trim replacing traditional wood for a sportier vibe. Seats are bolstered for support during spirited drives, featuring larger shift paddles for easy access. The layout exudes old-world charm with modern functionality, including an adjustable exhaust switch and sport mode activation.

While rear space suits adults for shorter journeys, the fuel tank’s positioning behind the seats slightly compromises boot capacity—a worthwhile trade for superior weight distribution. Materials feel premium, akin to a Louis Vuitton interior, pampering passengers with every touch.

Design and Aesthetic Appeal

Maserati’s Pininfarina-styled bodywork remains timeless, with the Sport GT adding aggressive 20-inch wheels, low-profile tires, and subtle badging to accentuate its persona. The elongated silhouette, flanked by tri-festoons and a trident grille, commands attention at any valet stand. Its presence blends sedan practicality with coupe-like allure, ideal for executives craving excitement.

GT S Evolution: Pushing Boundaries Further

The Sport GT S variant elevated the formula with a 4.7-liter V8 tuned to 433-450 bhp, shaving 0-62 times to 5.1 seconds. Engine tweaks, including remapped management and exhaust upgrades, unleashed power at higher revs without altering the redline. The ZF auto’s refinements made it a benchmark, smooth in auto and snappy in manual.

• Power: Up to 450 bhp at 7,000 rpm.
• 0-100 km/h: 5.1 seconds.
• Exhaust: Sport button amplifies Ferrari-esque howl.

Reviewers hailed it as the finest large sporting saloon, outpacing Audi S8 and Mercedes AMG in character.

Real-World Performance Insights

On northern Italy’s sweeping roads, the Sport GT proved its mettle, with the transmission’s speed matching the engine’s eagerness. Low-speed manners improved dramatically post-duo-select era, eliminating lurches for refined urban duties. Fuel economy lags at high CO2 figures, but efficiency wasn’t the priority—pure driving joy was.

Competitive Landscape

Against Porsche Panamera 4S or BMW M5, the Quattroporte prioritized soul over outright pace. Its V8 symphony and handling fluidity set it apart, though power deficits were noted. Warranty spanned 3 years with unlimited mileage in some markets, underscoring build confidence.
