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.

To help make backing safer, the Quattroporte’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 6 Series Gran Coupe doesn’t offer a cross-path warning system.

Both the Quattroporte and the 6 Series Gran Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems and around view monitors.

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.

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.

The Quattroporte’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The 6 Series Gran Coupe doesn’t offer drift compensation steering.

Because it has more passenger and cargo room, the EPA rates the Quattroporte a Large car, while the 6 Series Gran Coupe is rated a Compact.

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

The Quattroporte has 5.1 inches more front hip room, 7.6 inches more front shoulder room, .8 inches more rear headroom, .6 inches more rear hip room and .7 inches more rear shoulder room than the 6 Series Gran Coupe.

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.

The Quattroporte has a standard 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.

Heated windshield washer nozzles are standard on the Quattroporte to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 6 Series Gran Coupe doesn’t offer heated windshield washer nozzles.

Optional air conditioned front and rear seats keep the Quattroporte’s passengers comfortable and take the sting out of hot leather in summer. The 6 Series Gran Coupe doesn’t offer air-conditioned seats in the rear.

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.
