The Quattroporte has a standard Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The GS Series only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the Quattroporte and the GS Series have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
The battery on the Quattroporte is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Quattroporte’s battery 20 to 30 degrees cooler, its life is increased by years. The GS Series’ battery is in the hot engine compartment.
The Quattroporte S’ standard 3.0 turbo V6 produces 113 more horsepower (424 vs. 311) and 148 lbs.-ft. more torque (428 vs. 280) than the GS Series’ 3.5 DOHC V6. The Quattroporte GTS’ standard 3.8 turbo V8 produces 212 more horsepower (523 vs. 311) and 244 lbs.-ft. more torque (524 vs. 280) than the GS Series’ 3.5 DOHC V6.
In heavy traffic or at stoplights the Quattroporte’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The GS Series doesn’t offer an automatic engine start/stop system.
The Quattroporte has 3.6 gallons more fuel capacity than the GS Series (21 vs. 17.4 gallons), for longer range between fill-ups.
The Quattroporte has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The GS Series doesn’t offer a cap-less fueling system.
For better stopping power the Quattroporte’s brake rotors are larger than those on the GS Series:
GS Series F Sport
For better traction, the Quattroporte has larger standard tires than the GS Series (F:245/45R19 & R:275/40R19 vs. 235/45R18). The Quattroporte’s optional tires are larger than the largest tires available on the GS Series (F:245/40R20 & R:285/35R20 vs. F:235/40R19 & R:265/35R19).
The Quattroporte’s standard 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the GS Series’ standard 45 series tires. The Quattroporte’s optional 245/35R21 front and 285/30R21 rear tires have a lower 35 series front and 30 series rear profile than the GS Series F Sport’s 40 series front and 35 series rear tires.
For better ride, handling and brake cooling the Quattroporte has standard 19-inch wheels. Smaller 18-inch wheels are standard on the GS Series. The Quattroporte’s optional 21-inch wheels are larger than the 19-inch wheels optional on the GS Series.
The Quattroporte’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The GS Series doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the Quattroporte’s wheelbase is 12.6 inches longer than on the GS Series (124.8 inches vs. 112.2 inches).
For better handling and stability, the track (width between the wheels) on the Quattroporte is 2.3 inches wider in the front and 2.2 inches wider in the rear than on the GS Series.
The Quattroporte’s front to rear weight distribution is more even (50% to 50%) than the GS Series’ (53% to 47%). This gives the Quattroporte more stable handling and braking.
The front grille of the Quattroporte uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GS Series doesn’t offer active grille shutters.
Because it has more passenger and cargo room, the EPA rates the Quattroporte a Large car, while the GS Series is rated a Mid-size.
The Quattroporte has 15 cubic feet more passenger volume than the GS Series (114 vs. 99).
The Quattroporte has .6 inches more front headroom, 10.3 inches more front hip room, 7 inches more front shoulder room and 3.7 inches more rear hip room than the GS Series.
For enhanced passenger comfort on long trips the Quattroporte’s available rear seats recline. The GS Series’ rear seats don’t recline.
The Quattroporte has a larger trunk than the GS Series (18.7 vs. 18.4 cubic feet).
The Quattroporte’s standard rear seats fold to accommodate long and bulky cargo. The GS Series doesn’t offer folding rear seats, only a ski pass-through.
To make loading groceries and cargo easier when your hands are full, the Quattroporte’s trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The GS Series doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.
The Quattroporte has a maintenance free battery for long life without checking the battery’s water level. The GS Series doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.
The Quattroporte’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The GS Series’ cruise control switches are unlit, making them difficult to find at night and operate safely.
The Quattroporte’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The GS Series’ standard manually variable intermittent wipers have to be constantly adjusted.
Heated windshield washer nozzles are standard on the Quattroporte to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The GS Series doesn’t offer heated windshield washer nozzles.
A power rear sunshade and rear side window sunshades are standard in the Quattroporte to help block heat and glare for the rear passengers. The GS Series doesn’t offer rear side window sunshades.
Optional air conditioned front and rear seats keep the Quattroporte’s passengers comfortable and take the sting out of hot leather in summer. The GS Series doesn’t offer air-conditioned seats in the rear.
The Quattroporte has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the GS Series.
The Quattroporte offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The GS Series doesn’t offer a house-current electrical outlet.
