Compare the2024 Maserati QuattroporteVS 2023 BMW M5

For enhanced safety, the front and rear seat shoulder belts of the Maserati Quattroporte have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW M5 doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Maserati Quattroporte are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW M5 doesn’t offer height-adjustable seat belts.

The Quattroporte has standard whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The M5 doesn’t offer a whiplash protection system.

Both the Quattroporte and the M5 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Maserati vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Maserati above average in initial quality. With 10 more problems per 100 vehicles, BMW is rated lower.

On the EPA test cycle the Quattroporte gets better mileage than the M5:

The Quattroporte has a gallon more fuel capacity than the M5 (21.1 vs. 20.1 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 M5 doesn’t offer a cap-less fueling system.

The Quattroporte’s 245/35R21 front and 285/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the M5’s standard 40 series tires. The Quattroporte’s tires are lower profile than the M5’s optional 35 series tires.

For better ride, handling and brake cooling the Quattroporte has standard 21-inch wheels. Smaller 19-inch wheels are standard on the M5. The M5’s largest wheels are only 20-inches.

The Quattroporte has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the M5; it requires you to depend on roadside assistance and your vehicle will have to be towed.

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 M5 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the Quattroporte’s wheelbase is 7.4 inches longer than on the M5 (124.8 inches vs. 117.4 inches).

For better handling and stability, the track (width between the wheels) on the Quattroporte is .4 inches wider in the front and 2 inches wider in the rear than on the M5.

The Quattroporte’s front to rear weight distribution is more even (50% to 50%) than the M5’s (54.4% to 45.6%). This gives the Quattroporte more stable handling and braking.

For better maneuverability, the Quattroporte’s turning circle is 2.6 feet tighter than the M5’s (38.7 feet vs. 41.3 feet).

The design of the Maserati Quattroporte amounts to more than styling. The Quattroporte has an aerodynamic coefficient of drag of .28 Cd. That is lower than the M5 (.31 to .32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Quattroporte get better fuel mileage.

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 M5 doesn’t offer active grille shutters.

Because it has more passenger and cargo room, the EPA rates the Quattroporte a Large car, while the M5 is rated a Mid-size.

The Quattroporte has 11 cubic feet more passenger volume than the M5 (114 vs. 103).

For enhanced passenger comfort on long trips the Quattroporte’s available rear seats recline. The M5’s rear seats don’t recline.

The Quattroporte has a much larger trunk than the M5 (18.7 vs. 14 cubic feet).

The Quattroporte’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The M5 does not have an oil pressure gauge.

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 M5 doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Quattroporte has standard headlight washers to keep headlight output high. The M5 doesn’t offer headlight washers.

The Quattroporte has standard front air conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The M5 doesn’t offer air-conditioned seats in the rear.

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 M5 doesn’t offer a house-current electrical outlet.
