The A4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Integra doesn’t offer pre-crash pretensioners.

Both the A4 and Integra have child safety locks to prevent children from opening the rear doors. The A4 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Integra’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The A4 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. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Integra doesn’t offer a whiplash protection system.

The A4 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 Integra 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 A4 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Integra doesn’t offer all-wheel drive.

When descending a steep, off-road slope, the A4’s standard Hill Descent Control allows you to creep down safely. The Integra doesn’t offer Hill Descent Control.

The A4 Premium Plus/Prestige has a standard Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The Integra 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.

Both the A4 and Integra offer rear cross-traffic warning, but the A4 with Rear Cross-Traffic Assist also has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The Integra’s Rear Cross Traffic Monitor doesn’t automatically brake.

Both the A4 and the Integra have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available blind spot warning systems.

The Audi A4 weighs 463 to 609 pounds more than the Acura Integra. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH, results indicate that the Audi A4 is safer than the Acura Integra:

	A4	Integra
	Front Seat
STARS	5 Stars	5 Stars
Abdominal Force	219 lbs.	226 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
Spine Acceleration	56 G’s	60 G’s

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Warranty

The A4’s corrosion warranty is 7 years longer than the Integra’s (12 vs. 5 years).

There are over 12 percent more Audi dealers than there are Acura dealers, which makes it easier should you ever need service under the A4’s warranty.

Reliability

The Audi A4’s engine uses a cast iron block for durability, while the Integra’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

Engine

The A4’s 2.0 turbo 4-cylinder hybrid produces 61 more horsepower (261 vs. 200) and 81 lbs.-ft. more torque (273 vs. 192) than the Integra’s standard 1.5 turbo 4-cylinder.

Fuel Economy and Range

Regenerative brakes improve the A4’s fuel efficiency by converting inertia back into energy instead of wasting it. The Integra doesn’t offer a regenerative braking system.

The A4 has 2.9 gallons more fuel capacity than the Integra (15.3 vs. 12.4 gallons), for longer range between fill-ups.

Transmission

The A4 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Integra doesn’t offer an SMG.

The A4’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Integra doesn’t offer launch control.

Brakes and Stopping

For better stopping power the A4’s standard brake rotors are larger than those on the Integra:

	A4	Integra
Front Rotors	13.3 inches	12.3 inches
Rear Rotors	13 inches	11.1 inches

The A4’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Integra are solid, not vented.

The A4 stops much shorter than the Integra:

	A4	Integra
70 to 0 MPH	149 feet	178 feet	Car and Driver
60 to 0 MPH	105 feet	123 feet	Motor Trend

Tires and Wheels

For better traction, the A4 has larger tires than the Integra (245/40R18 vs. 215/50R17).

The A4’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Integra’s standard 50 series tires.

For better ride, handling and brake cooling the A4 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Integra.

Suspension and Handling

The A4 has standard front and rear gas-charged shocks for better control over choppy roads. The Integra’s suspension doesn’t offer gas-charged shocks.

For a smoother ride and more stable handling, the A4’s wheelbase is 3.3 inches longer than on the Integra (111 inches vs. 107.7 inches).

The A4’s front to rear weight distribution is more even (56% to 44%) than the Integra’s (60% to 40%). This gives the A4 more stable handling and braking.

The A4 Premium Plus handles at .97 G’s, while the Integra A-Spec Technology pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

The A4 Premium Plus executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the Integra A-Spec Technology (25.3 seconds @ .74 average G’s vs. 27.2 seconds @ .63 average G’s).

Cargo Capacity

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the A4 offers cargo security. The Integra’s hatchback body style and non-lockable folding seat defeat cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the A4. The Integra doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the A4’s available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The Integra doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Towing

The A4 has a 3968 lbs. towing capacity. The Integra has no towing capacity.

Servicing Ease

The A4 uses gas struts to support the hood for easier service access. The Integra uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the A4 is mounted longitudinally (North-South), instead of sideways, as in the Integra. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

The power windows standard on both the A4 and the Integra have locks to prevent small children from operating them. When the lock on the A4 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Integra prevents the driver from operating the other windows just as it does the other passengers.

The A4’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Integra’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the A4 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Integra can only close the windows from inside the vehicle, with the ignition on.

The A4’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Integra’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are standard on the A4 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Integra doesn’t offer heated windshield washer nozzles.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The A4’s headlights were rated “Good” to “Acceptable” by the IIHS, while the Integra’s headlights are rated “Acceptable.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A4 Prestige has standard headlight washers to keep headlight output high. The Integra doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the A4 has standard cornering lights to illuminate around corners when the turn signals are activated. The Integra doesn’t offer cornering lights.

Manual rear side window sunshades are available in the A4 to help block heat and glare for the rear passengers. The Integra doesn’t offer rear side window sunshades.

The A4’s standard rear view mirror and optional side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Integra has an automatic rear view mirror, but its side mirrors don’t dim.

Both the A4 and the Integra have standard heated front seats. The A4 Prestige also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Integra.

Optional air-conditioned seats in the A4 Premium Plus/Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Integra doesn’t offer air-conditioned seats.

On extremely cold winter days, the A4’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Integra doesn’t offer a heated steering wheel.

The A4 has a 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. Dual zone air conditioning is only available on the Integra A-Spec Technology/Type S.

Both the A4 and the Integra offer rear vents. For greater rear passenger comfort, the A4 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Integra doesn’t offer rear air conditioning vents, only heat vents.

With standard voice command, the A4 offers the driver hands free control of the radio, climate controls and the navigation computer by simply speaking. The Integra doesn’t offer a voice control system.

Compared to the Acura Integra, the Audi A4 eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries with its standard integrated Homelink® universal remote controlled from the rear view mirror.

The A4 Prestige’s Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Integra doesn’t offer an automated parking system.
