Compare the2023 BMW M5VS 2023 Maserati Quattroporte

The M5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Quattroporte doesn’t offer pre-crash pretensioners.

The BMW M5 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Quattroporte doesn’t offer knee airbags.

The M5 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Quattroporte doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The M5 offers an optional Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Quattroporte doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the M5. But it costs extra on the Quattroporte.

The M5’s 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 Quattroporte doesn’t offer a driver alert monitor.

Both the M5 and the Quattroporte 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The M5’s corrosion warranty is 8 years and unlimited miles longer than the Quattroporte’s (12/unlimited vs. 4/50,000).

BMW pays for scheduled maintenance on the M5 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Maserati doesn’t pay scheduled maintenance for the Quattroporte.

There are over 3 times as many BMW dealers as there are Maserati dealers, which makes it much easier should you ever need service under the M5’s warranty.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Maserati vehicles. J.D. Power ranks BMW above average in initial quality. With 90 more problems per 100 vehicles, Maserati is rated below average.

The M5 has more powerful engines than the Quattroporte:

Regenerative brakes improve the M5’s fuel efficiency by converting inertia back into energy instead of wasting it. The Quattroporte doesn’t offer a regenerative braking system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW M5 higher (3 out of 10) than the Maserati Quattroporte (1 to 3). This means the M5 produces up to 22.5 pounds less smog-producing pollutants than the Quattroporte every 15,000 miles.

For better stopping power the M5’s brake rotors are larger than those on the Quattroporte:

The M5 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Quattroporte doesn’t offer ceramic brake rotors.

For better traction, the M5 has larger front tires than the Quattroporte (F:275/40R19 & R:285/40R19 vs. F:245/40R20 & R:285/35R20).

The BMW M5 may be more efficient, handle and accelerate better because it weighs about 400 to 500 pounds less than the Maserati Quattroporte.

The M5 is 10.9 inches shorter than the Quattroporte, making the M5 easier to handle, maneuver and park in tight spaces.

The M5 has 2.1 inches more front headroom, .7 inches more rear headroom and .6 inches more rear shoulder room than the Quattroporte.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the M5 offers cargo security. The Quattroporte’s non-lockable folding seat and non-lockable remote release defeat cargo security.

Unlike the driver-only memory system in the Quattroporte, the M5 has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The M5 has a standard heads-up display that projects speed, tachometer, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Quattroporte doesn’t offer a heads-up display.

If the windows are left open on the M5 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Quattroporte can only close the windows from inside the vehicle, with the ignition on.

The M5 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 Quattroporte.

The M5 offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Quattroporte.

The M5’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Quattroporte doesn’t offer an automated parking system.

The BMW 5 Series outsold the Maserati Quattroporte by over 33 to one during 2022.
