Both the Ghibli and the S7 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height-adjustable front shoulder belts, traction control and electronic stability systems to prevent skidding.
The Ghibli has 1.3 gallons more fuel capacity than the S7 (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 S7 doesn’t offer a cap-less fueling system.
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 S7’s optional 35 series tires.
For better ride, handling and brake cooling the Ghibli offers optional 21-inch wheels. The S7’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 S7 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 S7 (118 inches vs. 114.7 inches).
The Ghibli’s front to rear weight distribution is more even (50% to 50%) than the S7’s (55% to 45%). This gives the Ghibli more stable handling and braking.
For better maneuverability, the Ghibli’s turning circle is .6 feet tighter than the S7’s (38.4 feet vs. 39 feet).
The Maserati Ghibli may be more efficient, handle and accelerate better because it weighs about 400 to 500 pounds less than the Audi S7.
The Ghibli has standard seating for 5 passengers; the S7 can only carry 4.
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 S7 doesn’t offer a remote starting system.
The Ghibli’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 S7 does not have an oil pressure gauge.
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 S7 doesn’t offer automatic dimming high beams.
A power rear sunshade is optional in the Ghibli to help block heat and glare for the rear passengers. The S7 doesn’t offer a rear sunshade.
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 S7’s mirrors don’t automatically adjust for backing.
