Safety Comparison

The A8’s front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Quattroporte doesn’t offer pre-crash pretensioners.

The A8 has a standard Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. The Quattroporte doesn’t offer a whiplash protection system.

The A8 offers optional Pre Sense Plus, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Quattroporte doesn't offer crash mitigation brakes.

The A8 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Quattroporte doesn’t offer all-wheel drive.

The Audi A8 has Daytime Running Lights to help keep it more visible under all conditions. Canadian government studies show that driving with lights during the day reduces accidents by 11% by making vehicles more conspicuous. The Quattroporte doesn’t offer Daytime Running Lights.

A passive infrared night vision system optional on the A8 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Quattroporte doesn’t offer a night vision system.

The A8’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Quattroporte doesn’t offer a lane departure warning system.

The A8’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Quattroporte doesn’t offer a system to reveal objects in the driver’s blind spots.

Both the A8 and the Quattroporte have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The A8’s corrosion warranty is 8 years and unlimited miles longer than the Quattroporte’s (12/unlimited vs. 4/50,000).

Audi pays for scheduled maintenance on the A8 for 1 year and 5000 miles. Audi will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. Maserati doesn’t pay scheduled maintenance for the Quattroporte.

There are almost 5 times as many Audi dealers as there are Maserati dealers, which makes it much easier should you ever need service under the A8’s warranty.

Engine Comparison

The A8 has more powerful engines than the Quattroporte:



A8 4.0T 4.0 turbo V8

420 HP

444 lbs.-ft.

A8 L W12 6.3 DOHC 12 cyl.

500 HP

463 lbs.-ft.

Quattroporte S 4.7 DOHC V8

425 HP

361 lbs.-ft.

Quattroporte Sport GT S 4.7 DOHC V8

433 HP

361 lbs.-ft.

Fuel Economy and Range Comparison

Regenerative brakes improve the A8’s fuel efficiency by converting inertia back into energy instead of wasting it. The Quattroporte doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the A8’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Quattroporte doesn’t offer an automatic engine start/stop system.

Brakes and Stopping Comparison

For better stopping power the A8 L W12’s front brake rotors are larger than those on the Quattroporte:

A8 L W12


Front Rotors

15.7 inches

14.2 inches

Rear Rotors

14 inches

13 inches

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The A8 has standard Hydraulic Brake Assist to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Quattroporte doesn’t offer a brake assist feature.

Tires and Wheels Comparison

For better traction, the A8 has larger standard tires than the Quattroporte (255/45R19 vs. 245/45R18). The A8’s optional tires are larger than the largest tires available on the Quattroporte (265/40R20 vs. 245/45R18).

For better ride, handling and brake cooling the A8 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Quattroporte.

Suspension and Handling Comparison

The front and rear suspension of the A8 uses air springs for a smoother, controlled ride than the Quattroporte, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The A8 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The A8’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Quattroporte doesn’t offer a load leveling suspension.

For better handling and stability, the track (width between the wheels) on the A8 is 2.4 inches wider in the front and 1.6 inches wider in the rear than on the Quattroporte.

The A8 L handles at .93 G’s, while the Quattroporte pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The A8 goes through Road & Track’s slalom 2.9 MPH faster than the Quattroporte (68.7 vs. 65.8 MPH).

The A8 executes Motor Trend’s “Figure Eight” maneuver quicker than the Quattroporte S (25.7 seconds @ .73 average G’s vs. 26.3 seconds @ .67 average G’s).

Chassis Comparison

The A8 4.0T uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Quattroporte doesn’t offer active noise cancellation.

Passenger Space Comparison

The A8 has .7 inches more front headroom and 3.1 inches more rear headroom than the Quattroporte.

Ergonomics Comparison

The A8 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 driver can also remotely turn on the heater or air conditioner. The Quattroporte doesn’t offer a remote starting system.

The A8’s standard power windows have a locking feature to keep children in the rear seat from operating them. Maserati does not offer a locking feature on the Quattroporte’s power windows.

Heated windshield washer nozzles are standard on the A8 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Quattroporte doesn’t offer heated windshield washer nozzles.

While driving with high beams on, sensitive light sensors available for the A8 detect other vehicles, which could be blinded and automatically switch to low beams. The Quattroporte doesn’t offer automatic dimming high beams.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the A8 has standard extendable sun visors. The Quattroporte doesn’t offer extendable visors.

To keep a safe, consistent following distance, the A8 offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Quattroporte doesn’t offer an adaptive cruise control.

The A8’s standard separate stalk mounted cruise control is close at hand. The Quattroporte’s standard cruise control is on an over-crowded turn signal stalk.

The A8’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 Quattroporte’s navigation system doesn’t offer real-time traffic updates.

The A8 L offers an optional 115-volt a/c outlet, allowing you to recharge a laptop or run small household appliances without special adapters, which can break or get misplaced. The Quattroporte doesn’t offer a house-current electrical outlet.
