Safety

For enhanced safety, the front and rear seat shoulder belts of the Audi S5 Sportback have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Nissan Maxima doesn’t offer pretensioners for the rear seat belts.

The S5 Sportback’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Maxima doesn’t offer pre-crash pretensioners.

The S5 Sportback has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Maxima 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 S5 Sportback has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Maxima doesn’t offer all-wheel drive.

Both the S5 Sportback and the Maxima have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The S5 Sportback comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Maxima’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The S5 Sportback’s corrosion warranty is 7 years longer than the Maxima’s (12 vs. 5 years).

Reliability

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Nissan vehicles. Consumer Reports ranks Audi 7 places higher in reliability than Nissan.

Engine

The S5 Sportback’s 3.0 turbo V6 produces 49 more horsepower (349 vs. 300) and 108 lbs.-ft. more torque (369 vs. 261) than the Maxima’s 3.5 DOHC V6.

As tested in Car and Driver the Audi S5 Sportback is faster than the Nissan Maxima:

Fuel Economy and Range

On the EPA test cycle the S5 Sportback gets better fuel mileage than the Maxima (21 city/30 hwy vs. 20 city/30 hwy).

Regenerative brakes improve the S5 Sportback’s fuel efficiency by converting inertia back into energy instead of wasting it. The Maxima doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the S5 Sportback’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 Maxima doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi S5 Sportback higher (5 out of 10) than the Nissan Maxima (3). This means the S5 Sportback produces up to 16.5 pounds less smog-producing pollutants than the Maxima every 15,000 miles.

Tires and Wheels

For better traction, the S5 Sportback’s optional tires are larger than the largest tires available on the Maxima (265/30R20 vs. 245/45R18).

The S5 Sportback’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 Maxima’s standard 45 series tires. The S5 Sportback’s optional tires have a lower 30 series profile than the Maxima SR/Platinum’s 40 series tires.

For better ride, handling and brake cooling the S5 Sportback offers optional 20-inch wheels. The Maxima’s largest wheels are only 19-inches.

Suspension and Handling

The S5 Sportback offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Maxima’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the S5 Sportback’s wheelbase is 1.9 inches longer than on the Maxima (111.2 inches vs. 109.3 inches).

The S5 Sportback’s front to rear weight distribution is more even (56% to 44%) than the Maxima’s (60.7% to 39.3%). This gives the S5 Sportback more stable handling and braking.

The S5 Sportback Prestige handles at .93 G’s, while the Maxima Platinum pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The S5 Sportback Prestige executes Motor Trend’s “Figure Eight” maneuver 2 seconds quicker than the Maxima Platinum (25 seconds @ .76 average G’s vs. 27 seconds @ .67 average G’s).

Chassis

The S5 Sportback is 5.7 inches shorter than the Maxima, making the S5 Sportback easier to handle, maneuver and park in tight spaces.

The design of the Audi S5 Sportback amounts to more than styling. The S5 Sportback has an aerodynamic coefficient of drag of .29 Cd. That is lower than the Maxima (.29 to .3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the S5 Sportback get better fuel mileage.

Passenger Space

The S5 Sportback has .3 inches more rear headroom and .9 inches more rear legroom than the Maxima.

Cargo Capacity

The S5 Sportback has a much larger trunk with its rear seat up than the Maxima (21.8 vs. 14.3 cubic feet).

To make loading and unloading groceries and cargo easier when your hands are full, the S5 Sportback’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The Maxima doesn’t offer a power or hands-free opening trunk.

Servicing Ease

The engine in the S5 Sportback is mounted longitudinally (North-South), instead of sideways, as in the Maxima. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Audi service is better than Nissan. J.D. Power ranks Audi third in service department satisfaction. With a 47% lower rating, Nissan is ranked 20th.

Ergonomics

The S5 Sportback Prestige 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 Maxima doesn’t offer a heads-up display.

The power windows standard on both the S5 Sportback and the Maxima have locks to prevent small children from operating them. When the lock on the S5 Sportback is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Maxima prevents the driver from operating the other windows just as it does the other passengers.

The S5 Sportback’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 Maxima’s rear power window switches have to be held the entire time to open or close them fully.

The S5 Sportback’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 Maxima’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 S5 Sportback to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Maxima doesn’t offer heated windshield washer nozzles.

The S5 Sportback’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Nissan only offers heated mirrors on the Maxima SV/SL/SR/Platinum.

The S5 Sportback Prestige’s Park Steering Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Maxima doesn’t offer an automated parking system.

Model Availability

The Audi S5 comes in coupe, convertible and four door hatchback bodystyles; the Nissan Maxima isn’t available as a coupe or convertible.

Economic Advantages

The S5 Sportback will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the S5 Sportback will retain 51.38% to 51.57% of its original price after five years, while the Maxima only retains 36.9% to 38.7%.
