Compare the2024 Maserati GranTurismoVS 2024 Porsche 718 Cayman

Over 200 people are killed each year when backed over by motor vehicles. The GranTurismo has standard Rear Emergency Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 718 Cayman doesn’t offer backup collision prevention brakes.

The GranTurismo has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 718 Cayman doesn’t offer all-wheel drive.

The GranTurismo’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The 718 Cayman doesn’t offer a lane departure warning system.

The GranTurismo offers an optional Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The 718 Cayman 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.

To help make backing out of a parking space safer, the GranTurismo’s optional Rear Cross Path uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 718 Cayman doesn’t offer a rear cross-path warning system.

The GranTurismo’s optional driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The 718 Cayman doesn’t offer a driver alert monitor.

Both the GranTurismo and the 718 Cayman have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available blind spot warning systems.

The Maserati GranTurismo weighs 838 to 1032 pounds more than the Porsche 718 Cayman. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The GranTurismo has more powerful engines than the 718 Cayman:

On the EPA test cycle the GranTurismo gets better mileage than the 718 Cayman:

The GranTurismo has 4.3 gallons more fuel capacity than the 718 Cayman’s standard fuel tank (18.5 vs. 14.2 gallons), for longer range between fill-ups. The GranTurismo has 1.6 gallons more fuel capacity than the 718 Cayman’s optional fuel tank (18.5 vs. 16.9 gallons).

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Maserati GranTurismo higher (5 out of 10) than the Porsche 718 Cayman (1 to 5). This means the GranTurismo produces up to 39 pounds less smog-producing pollutants than the 718 Cayman every 15,000 miles.

The Maserati GranTurismo comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the 718 Cayman.

An eight-speed automatic is standard on the Maserati GranTurismo, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the 718 Cayman.

All wheel drive, available in the GranTurismo, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Porsche 718 Cayman is not available with all wheel drive.

For better stopping power the GranTurismo’s standard brake rotors are larger than those on the 718 Cayman:

For better traction, the GranTurismo has larger tires than the 718 Cayman (F:265/30R20 & R:295/30R21 vs. F:235/45R18 & R:265/45R18). The GranTurismo’s front tires are larger than the largest tires available on the 718 Cayman (F:265/30R20 & R:295/30R21 vs. F:245/35R20 & R:295/30R20).

The GranTurismo’s tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the 718 Cayman’s standard 45 series tires. The GranTurismo’s tires are lower profile than the 718 Cayman GT4 RS’ 35 series front tires.

For better ride, handling and brake cooling the GranTurismo has standard 20-inch front and 21-inch rear wheels. Smaller 18-inch wheels are standard on the 718 Cayman. The 718 Cayman’s largest wheels are only 20-inches.

The front and rear suspension of the GranTurismo uses air springs for a smoother, controlled ride than the 718 Cayman, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The GranTurismo has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GranTurismo’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The 718 Cayman doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the GranTurismo’s wheelbase is 17.9 inches longer than on the 718 Cayman (115.3 inches vs. 97.4 inches).

For better handling and stability, the track (width between the wheels) on the GranTurismo is 4.8 inches wider in the front and 5 inches wider in the rear than the average track on the 718 Cayman.

The GranTurismo’s front to rear weight distribution is more even (52% to 48%) than the 718 Cayman’s (44.7% to 55.3%). This gives the GranTurismo more stable handling and braking.

The design of the Maserati GranTurismo amounts to more than styling. The GranTurismo has an aerodynamic coefficient of drag of .28 Cd. That is lower than the 718 Cayman (.3 to .34). A more efficient exterior helps the GranTurismo go faster and keeps the interior quieter. It also helps the GranTurismo get better fuel mileage.

The front grille of the GranTurismo uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The 718 Cayman doesn’t offer active grille shutters.

The GranTurismo has standard seating for 4 passengers; the 718 Cayman can only carry 2.

The GranTurismo has 41 cubic feet more passenger volume than the 718 Cayman (89 vs. 48).

To make loading and unloading groceries and cargo easier, especially for short adults, the GranTurismo offers an optional power trunk, which opens and closes automatically by pressing a button or just by kicking your foot under the back bumper, completely leaving your hands free. The 718 Cayman doesn’t offer a power trunk, so its trunk has to be closed manually.

The GranTurismo offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 718 Cayman doesn’t offer a remote starting system.

Unlike the driver-only memory system optional at extra cost in the 718 Cayman, the GranTurismo has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GranTurismo offers an optional heads-up display that projects speed, tachometer, navigation instruction and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 718 Cayman doesn’t offer a heads-up display.

If the windows are left open on the GranTurismo the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the 718 Cayman can only operate the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are standard on the GranTurismo to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 718 Cayman doesn’t offer heated windshield washer nozzles.

The GranTurismo’s LED headlights produce a white, bright light using less electricity than the 718 Cayman’s standard xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the GranTurismo has standard extendable sun visors. The 718 Cayman doesn’t offer extendable visors.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Maserati GranTurismo has a standard wireless phone charging system (Qi) in the center console. The 718 Cayman doesn’t offer wireless personal charging.
