Compare the2024 Lexus LSVS 2023 Maserati Quattroporte

The LS’ 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 Lexus LS 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 LS has standard Secondary Collision Brake, which automatically apply 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 LS has a standard Parking Support Brake 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.

Both the LS and Quattroporte have rear cross-traffic warning, but the LS has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The Quattroporte’s Rear Cross Path doesn’t automatically brake.

The LS’ 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 LS and the Quattroporte have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear 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, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.

Lexus’ powertrain warranty covers the LS 2 years and 20,000 miles longer than Maserati covers the Quattroporte. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Quattroporte ends after only 4 years or 50,000 miles.

The LS’ corrosion warranty is 2 years and unlimited miles longer than the Quattroporte’s (6/unlimited vs. 4/50,000).

There are over 2 times as many Lexus dealers as there are Maserati dealers, which makes it much easier should you ever need service under the LS’ warranty.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the LS’ reliability 40 points higher than the Quattroporte.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Maserati vehicles. J.D. Power ranks Lexus above average in initial quality. With 11 more problems per 100 vehicles, Maserati is rated lower.

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

The LS can travel with zero emissions on a full charge for .6 miles. The Quattroporte can’t move without running its internal combustion engine.

Regenerative brakes improve the LS 500h’s fuel efficiency by converting inertia back into energy instead of wasting it. The Quattroporte doesn’t offer a regenerative braking system.

The LS Hybrid’s standard fuel tank has 1.1 gallons more fuel capacity than the Quattroporte (22.2 vs. 21.1 gallons).

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus LS higher (5 to 7 out of 10) than the Maserati Quattroporte (1 to 3). This means the LS produces up to 47 pounds less smog-producing pollutants than the Quattroporte every 15,000 miles.

A 10-speed automatic is standard on the Lexus LS, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Quattroporte.

The LS 500h has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Quattroporte doesn’t offer a CVT.

For better stopping power the LS 500 F Sport’s front brake rotors are larger than those on the Quattroporte:

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the LS can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Quattroporte doesn’t offer run-flat tires.

The LS F-Sport offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Quattroporte doesn’t offer an active sway bar system.

The LS has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The LS’ 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 Quattroporte doesn’t offer a load leveling suspension.

For better maneuverability, the LS’ turning circle is 3.7 feet tighter than the Quattroporte’s (36.8 feet vs. 40.5 feet). The LS AWD’s turning circle is 1.1 feet tighter than the Quattroporte’s (39.4 feet vs. 40.5 feet).

The LS uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Quattroporte doesn’t offer active noise cancellation.

With its sedan body style, valet key and remote trunk release lockout, the LS 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 LS 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 and climate settings and the front passenger seat also adjusts to the new passenger’s preset preferences.

The LS has a standard 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 Quattroporte doesn’t offer a heads-up display.

If the windows are left open on the LS the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Lexus service department.) The driver of the Quattroporte can only close the windows from inside the vehicle, with the ignition on.

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

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

The LS’ optional Advanced Park 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 Lexus LS outsold the Maserati Quattroporte by over four to one during 2022.
