The CLS’ 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 CLS’ 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.

The CLS has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Quattroporte doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the CLS and the Quattroporte have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras, available all wheel drive, lane departure warning systems, around view monitors and rear cross-path warning.

The CLS’ corrosion warranty is 1 year and unlimited miles longer than the Quattroporte’s (5/unlimited vs. 4/50,000).

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

J.D. Power and Associates rated the CLS first among midsize premium cars in their 2019 Initial Quality Study. The Quattroporte isn’t in the top three in its category.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes CLS higher (6 out of 10) than the Maserati Quattroporte (1). This means the CLS produces up to 45.9 pounds less smog-producing pollutants than the Quattroporte every 15,000 miles.

A nine-speed automatic is standard on the Mercedes CLS, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Quattroporte.

Tires and Wheels

The CLS’ standard 245/40R19 front and 275/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Quattroporte’s standard 45 series front and 40 series rear tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the CLS 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.

Suspension and Handling

The CLS has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The CLS’ 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 CLS’ turning circle is .6 feet tighter than the Quattroporte’s (38.1 feet vs. 38.7 feet).

The CLS is 10.8 inches shorter than the Quattroporte, making the CLS easier to handle, maneuver and park in tight spaces.

The CLS’ standard rear seats fold to accommodate long and bulky cargo. The Quattroporte doesn’t offer folding rear seats.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the CLS 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 CLS has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The CLS offers an optional heads-up display that projects speed and other key instrumentation 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 CLS 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 operate the windows from inside the vehicle, with the ignition on.

The CLS’ optional Active Parking Assist 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.

J.D. Power and Associates rated the CLS second among midsize premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Quattroporte isn’t in the top three.
