Compare the2023 BMW M8VS 2023 Maserati Quattroporte

The M8’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 M8 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 M8 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 M8 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 M8. But it costs extra on the Quattroporte.

The M8’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 M8 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, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

The M8’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 M8 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 M8’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 M8’s 4.4 turbo V8 produces 272 more horsepower (617 vs. 345) and 184 lbs.-ft. more torque (553 vs. 369) than the Quattroporte GT’s standard 3.0 turbo V6. The M8’s 4.4 turbo V8 produces 193 more horsepower (617 vs. 424) and 125 lbs.-ft. more torque (553 vs. 428) than the Quattroporte Modena’s standard 3.0 turbo V6. The M8’s 4.4 turbo V8 produces 37 more horsepower (617 vs. 580) and 15 lbs.-ft. more torque (553 vs. 538) than the Quattroporte Trofeo’s standard 3.8 turbo V8.

Regenerative brakes improve the M8’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 M8 higher (3 out of 10) than the Maserati Quattroporte (1 to 3). This means the M8 produces up to 22.5 pounds less smog-producing pollutants than the Quattroporte every 15,000 miles.

For better stopping power the M8’s brake rotors are larger than those on the Quattroporte:

The M8 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 M8 has larger front tires than the Quattroporte (F:275/35R20 & R:285/35R20 vs. F:245/40R20 & R:285/35R20).

The M8’s tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Quattroporte’s standard 40 series front tires.

For better maneuverability, the M8 Competition Coupe’s turning circle is 1.5 feet tighter than the Quattroporte’s (39 feet vs. 40.5 feet).

The BMW M8 may be more efficient, handle and accelerate better because it weighs about 200 to 300 pounds less than the Maserati Quattroporte.

The M8 Gran Coupe is 1 foot, 3.5 inches shorter than the Quattroporte, making the M8 easier to handle, maneuver and park in tight spaces.

Pulling a handle automatically lowers the M8’s rear seats, to make changing between passengers and cargo easier. The Quattroporte doesn’t offer automatic folding seats.

With its coupe, convertible or sedan body style, valet key, locking rear seatbacks and remote trunk release in the glovebox, the M8 offers cargo security. The Quattroporte’s non-lockable folding seat and non-lockable remote release defeat cargo security.

The M8 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 M8 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.

Laser headlights, standard on the M8, produce their light by firing blue lasers through phosphorus, a process that uses one-half the power of the Quattroporte’s LED headlights. Laser headlights can have double the range of LEDs with a much smaller surface area.

The M8 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 M8’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 M8 comes in coupe, convertible and sedan bodystyles; the Maserati Quattroporte isn’t available as a coupe or convertible.

The BMW 8 Series outsold the Maserati Quattroporte by almost 12 to one during 2022.
