For enhanced safety, the front and rear seat shoulder belts of the Maserati Ghibli 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 Audi S6 doesn’t offer pretensioners for the rear seat belts.
Both the Ghibli and the S6 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.
The Ghibli has 1.3 gallons more fuel capacity than the S6 (21.1 vs. 19.8 gallons), for longer range between fill-ups.
The Ghibli 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 S6 doesn’t offer a cap-less fueling system.
The Ghibli stops shorter than the S6:
70 to 0 MPH
Car and Driver
The Ghibli’s optional 285/30R21 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the S6’s optional 35 series tires.
For better ride, handling and brake cooling the Ghibli offers optional 21-inch wheels. The S6’s largest wheels are only 20-inches.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Ghibli can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The S6 doesn’t offer run-flat tires.
For a smoother ride and more stable handling, the Ghibli’s wheelbase is 3.3 inches longer than on the S6 (118 inches vs. 114.7 inches).
For better handling and stability, the track (width between the wheels) on the Ghibli is .8 inches wider in the front and 1.9 inches wider in the rear than on the S6.
The Ghibli’s front to rear weight distribution is more even (50% to 50%) than the S6’s (57% to 43%). This gives the Ghibli more stable handling and braking.
The Ghibli S Q4 handles at .91 G’s, while the S6 pulls only .87 G’s of cornering force in a Car and Driver skidpad test.
For better maneuverability, the Ghibli’s turning circle is .6 feet tighter than the S6’s (38.4 feet vs. 39 feet).
The Maserati Ghibli may be more efficient, handle and accelerate better because it weighs about 250 to 400 pounds less than the Audi S6.
Because it has more passenger and cargo room, the Ghibli is rated a Large car by the EPA, while the S6 is rated a Mid-size.
The Ghibli has 10 cubic feet more passenger volume than the S6 (108 vs. 98).
The Ghibli has 1.6 inches more front headroom, .3 inches more front shoulder room, 1 inch more rear headroom and .2 inches more rear shoulder room than the S6.
The Ghibli has a much larger trunk than the S6 (17.6 vs. 14.1 cubic feet).
The Ghibli 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 S6 doesn’t offer a remote starting system.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Ghibli offers available headlight washers to keep headlight output high. The S6 doesn’t offer headlight washers.
While driving with high beams on, sensitive light sensors available for the Ghibli detect other vehicles which could be blinded and automatically switch to low beams. The S6 doesn’t offer automatic dimming high beams.
When the Ghibli with available tilt-down mirrors is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The S6’s mirrors don’t automatically adjust for backing.
