Safety Comparison

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 6 Series Gran Coupe doesn’t offer pretensioners for the 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 6 Series Gran Coupe doesn’t offer height-adjustable seat belts.

Both the Quattroporte and the 6 Series Gran Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, traction control and electronic stability systems to prevent skidding.

The Quattroporte has 2.6 gallons more fuel capacity than the 6 Series Gran Coupe’s standard fuel tank (21.1 vs. 18.5 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 6 Series Gran Coupe doesn’t offer a cap-less fueling system.

Rear Rotors

Tires and Wheels Comparison

For better traction and acceleration, the Quattroporte has larger standard rear tires than the 6 Series Gran Coupe (275/40R19 vs. 245/45R18). The Quattroporte’s optional rear tires are larger than the largest rear tires available on the 6 Series Gran Coupe (285/35R20 vs. 275/35R19).

The Quattroporte’s standard 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the 640i Gran Coupe’s standard 45 series tires.

For better ride, handling and brake cooling the Quattroporte has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 640i Gran Coupe. The Quattroporte’s optional 21-inch wheels are larger than the 20-inch wheels optional on the 6 Series Gran Coupe.

Suspension and Handling Comparison

For a smoother ride and more stable handling, the Quattroporte’s wheelbase is 8.1 inches longer than on the 6 Series Gran Coupe (124.8 inches vs. 116.7 inches).

For better maneuverability, the Quattroporte’s turning circle is .7 feet tighter than the 6 Series Gran Coupe’s (38.7 feet vs. 39.4 feet). The Quattroporte’s turning circle is 2.3 feet tighter than the M6 Gran Coupe’s (38.7 feet vs. 41 feet).

Passenger Space Comparison

Because it has more passenger and cargo room, the Quattroporte is rated a Large car by the EPA, while the 6 Series Gran Coupe is rated a Mid-size.

The Quattroporte has 17 cubic feet more passenger volume than the 6 Series Gran Coupe (114 vs. 97).

For enhanced passenger comfort on long trips the Quattroporte’s available rear seats recline. The 6 Series Gran Coupe’s rear seats don’t recline.

Cargo Capacity Comparison

The Quattroporte has a much larger trunk than the 6 Series Gran Coupe with its rear seat up (18.7 vs. 16.2 cubic feet).

Ergonomics Comparison

The Quattroporte offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 6 Series Gran Coupe doesn’t offer a remote starting system.

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 6 Series Gran Coupe does not have an oil pressure gauge.

Keyless Go standard on the Quattroporte allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip (optional Extended Keyless Go will also allow unlocking the passenger doors without taking your keys out). The BMW 6 Series Gran Coupe’s Comfort Access doesn’t unlock the trunk.

To help keep rear passengers entertained, the Quattroporte offers optional rear seat controls for the radio. The 6 Series Gran Coupe doesn’t offer rear seat audio controls.

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 6 Series Gran Coupe doesn’t offer a house-current electrical outlet.
