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 Aston Martin Rapide doesn’t offer height-adjustable seat belts.
The Quattroporte has standard whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The Rapide doesn’t offer a whiplash protection system.
The Quattroporte S has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Rapide doesn’t offer all-wheel drive.
Both the Quattroporte and the Rapide have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, traction control and electronic stability systems to prevent skidding.
The Quattroporte comes with a full 4 year/50,000 mile basic warranty, which covers the entire car and includes free 24 hour roadside assistance. The Rapide’s 3 year basic warranty expires 1 year sooner.
There are almost 5 times as many Maserati dealers as there are Aston Martin dealers, which makes it much easier should you ever need service under the Quattroporte’s warranty.
The Quattroporte GTS’ standard 3.8 turbo V8 produces 67 lbs.-ft. more torque (524 vs. 457) than the Rapide’s 5.9 DOHC V12.
On the EPA test cycle the Quattroporte GTS gets better fuel mileage than the Rapide (13 city/22 hwy vs. 13 city/19 hwy).
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 Rapide doesn’t offer a cap-less fueling system.
The Quattroporte’s optional 245/35R21 front and 285/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the Rapide’s 40 series front and 35 series rear tires.
For better ride, handling and brake cooling the Quattroporte offers optional 21-inch wheels. The Rapide’s largest wheels are only 20-inches.
The Quattroporte has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Rapide, it requires you to depend on roadside assistance and your vehicle will have to be towed.
For a smoother ride and more stable handling, the Quattroporte’s wheelbase is 7.1 inches longer than on the Rapide (124.8 inches vs. 117.7 inches).
For better handling and stability, the track (width between the wheels) on the Quattroporte is 1.7 inches wider in the front and 1.3 inches wider in the rear than on the Rapide.
For better maneuverability, the Quattroporte’s turning circle is 2.3 feet tighter than the Rapide’s (38.7 feet vs. 41 feet).
Because it has more passenger and cargo room, the Quattroporte is rated a Large car by the EPA, while the Rapide is rated a Minicompact.
The Quattroporte has standard seating for 5 passengers; the Rapide can only carry 4.
The Quattroporte has 41 cubic feet more passenger volume than the Rapide (114 vs. 73).
For enhanced passenger comfort on long trips the Quattroporte’s available rear seats recline. The Rapide’s rear seats don’t recline.
The Quattroporte’s standard folding rear seats are split to accommodate bulky cargo. The Rapide’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.
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 Rapide 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 Rapide 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 Aston Martin Rapide doesn’t offer an advanced key 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 Quattroporte has standard headlight washers to keep headlight output high. The Rapide doesn’t offer headlight washers.
While driving with high beams on, sensitive light sensors standard on the Quattroporte detect other vehicles which could be blinded and automatically switch to low beams. The Rapide doesn’t offer automatic dimming high beams.
To help drivers see further while navigating curves, the Quattroporte has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Rapide doesn’t offer cornering lights.
The Quattroporte has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Rapide has an automatic rear view mirror, but its side mirrors don’t dim.
The Quattroporte’s standard GPS navigation system has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service available in a limited number of metro areas.) The Rapide’s navigation system doesn’t offer real-time traffic updates.
