The S8’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Rapide doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Audi S8 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 S8 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Rapide doesn’t offer front seat center airbags.

The S8 has standard Pre Sense Front, 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 Rapide doesn't offer collision warning or crash mitigation brakes.

The S8 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Rapide doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The S8 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Rapide doesn’t offer all-wheel drive.

The Audi S8 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 Rapide doesn’t offer Daytime Running Lights.

A passive infrared night vision system optional on the S8 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 and even aims one of the vehicle’s headlights in the direction of the person or object. The Rapide doesn’t offer a night vision system.

The S8’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Rapide doesn’t offer a lane departure warning system.

The S8 has a standard Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The Rapide only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The S8’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 Rapide doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing safer, the S8’s optional 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 Rapide doesn’t offer a cross-path warning system.

The S8 has standard Audi Connect Care, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Rapide doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the S8 and the Rapide have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and rearview cameras.

The Audi S8 weighs 915 pounds more than the Aston Martin Rapide. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The S8 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Rapide’s 3-year basic warranty expires 1 year sooner.

The S8’s corrosion warranty is 2 years longer than the Rapide’s (12 vs. 10 years).

There are almost 9 times as many Audi dealers as there are Aston Martin dealers, which makes it much easier should you ever need service under the S8’s warranty.

Regenerative brakes improve the S8’s fuel efficiency by converting inertia back into energy instead of wasting it. The Rapide doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the S8’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 Rapide doesn’t offer an automatic engine start/stop system.

For better traction, the S8 has larger tires than the Rapide (265/40R20 vs. 245/40R20).

The S8’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Rapide’s 40 series front tires.

For better ride, handling and brake cooling the S8 offers optional 21-inch wheels. The Rapide’s largest wheels are only 20-inches.

The S8 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.

Suspension and Handling

The front and rear suspension of the S8 uses air springs for a smoother, controlled ride than the Rapide, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The S8 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The S8’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 Rapide doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the S8’s wheelbase is 5.5 inches longer than on the Rapide (123.2 inches vs. 117.7 inches).

For better handling and stability, the track (width between the wheels) on the S8 is 1.5 inches wider in the front and .1 inches wider in the rear than on the Rapide.

With its sedan body style, valet key and remote trunk release lockout, the S8 offers cargo security. The Rapide’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the S8. The Rapide doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier when your hands are full, the S8’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The Rapide doesn’t offer a power or hands-free opening liftgate.

The S8’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The Rapide doesn’t offer an easy entry system.

The S8 has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Rapide doesn’t offer a heads-up display.

Audi Advanced Key standard on the S8 allows you to unlock the doors, 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. 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 S8 offers available 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 S8 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 avoid possible obstacles, the S8 has standard cornering lights to illuminate around corners when the turn signals are activated. The Rapide doesn’t offer cornering lights. The S8 also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the S8 has standard extendable sun visors. The Rapide doesn’t offer extendable visors.

The S8’s sun-visors swivel front-to-side to block glare from the side windows. The Rapide’s visors are fixed into the windshield header.

Power rear and rear side window sunshades are standard in the S8 to help block heat and glare for the rear passengers. The Rapide doesn’t offer a rear or rear side window sunshades.

The S8 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 offers an automatic rear view mirror, but its side mirrors don’t dim.

On extremely cold winter days, the S8’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Rapide doesn’t offer a heated steering wheel.

The S8 has standard massaging front and optional massaging rear seats. Massaging seats aren’t available in the Rapide.

The S8’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Rapide doesn’t offer dual zone air conditioning.

To keep a safe, consistent following distance, the S8 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 Rapide doesn’t offer an adaptive cruise control.

With standard voice command, the S8 offers the driver hands free control of the radio, climate controls and the navigation computer by simply speaking. The Rapide doesn’t offer a voice control system.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi S8 has a standard wireless phone charging system (Qi) in the center console. The Rapide doesn’t offer wireless personal charging.

The S8 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 Rapide doesn’t offer a house-current electrical outlet.
