For enhanced safety, the front and rear seat shoulder belts of the Audi RS 5 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 Alfa Romeo Giulia Quadrifoglio doesn’t offer pretensioners for its rear seat belts.

The RS 5 Sportback’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Giulia Quadrifoglio doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Audi RS 5 Sportback 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 Alfa Romeo Giulia Quadrifoglio doesn’t offer height-adjustable seat belts.

Both the RS 5 Sportback and Giulia Quadrifoglio have child safety locks to prevent children from opening the rear doors. The RS 5 Sportback 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 Giulia Quadrifoglio’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 RS 5 Sportback’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Giulia Quadrifoglio doesn’t offer a whiplash protection system.

The RS 5 Sportback 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 Giulia Quadrifoglio 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 RS 5 Sportback has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Giulia Quadrifoglio doesn’t offer all-wheel drive.

When descending a steep, off-road slope, the RS 5 Sportback’s standard Hill Descent Control allows you to creep down safely. The Giulia Quadrifoglio doesn’t offer Hill Descent Control.

The RS 5 Sportback offers an optional Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The Giulia Quadrifoglio 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 RS 5 Sportback and the Giulia Quadrifoglio have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.

Warranty

The RS 5 Sportback’s corrosion warranty is 7 years longer than the Giulia Quadrifoglio’s (12 vs. 5 years).

There are over 2 times as many Audi dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the RS 5 Sportback’s warranty.

Reliability

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Alfa Romeo With 13 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Audi higher than Alfa Romeo.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Audi vehicles are more reliable than Alfa Romeo vehicles. Consumer Reports ranks Audi 15 places higher in reliability than Alfa Romeo.

Engine

Fuel Economy and Range

On the EPA test cycle the RS 5 Sportback gets better fuel mileage than the Giulia Quadrifoglio (18 city/25 hwy vs. 17 city/25 hwy).

Regenerative brakes improve the RS 5 Sportback’s fuel efficiency by converting inertia back into energy instead of wasting it. The Giulia Quadrifoglio doesn’t offer a regenerative braking system.

Environmental Friendliness

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

Brakes and Stopping

For better stopping power the RS 5 Sportback’s front brake rotors are larger than those on the Giulia Quadrifoglio:

	RS 5 Sportback	RS 5 Sportback	Giulia Quadrifoglio
Front Rotors	14.8 inches	15.7 inches	14.2 inches

The RS 5 Sportback offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Giulia Quadrifoglio doesn’t offer ceramic brake rotors.

The RS 5 Sportback stops shorter than the Giulia Quadrifoglio:

	RS 5 Sportback	Giulia Quadrifoglio
70 to 0 MPH	154 feet	157 feet	Car and Driver

Tires and Wheels

For better traction, the RS 5 Sportback has larger standard tires than the Giulia Quadrifoglio (265/35R19 vs. 245/35R19). The RS 5 Sportback’s optional tires are larger than the largest tires available on the Giulia Quadrifoglio (275/30R20 vs. 245/35R19).

The RS 5 Sportback’s optional tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the Giulia Quadrifoglio’s 35 series front tires.

For better ride, handling and brake cooling the RS 5 Sportback offers optional 20-inch wheels. The Giulia Quadrifoglio’s largest wheels are only 19-inches.

The RS 5 Sportback 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 Giulia Quadrifoglio; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the RS 5 Sportback is 1.7 inches wider in the front than on the Giulia Quadrifoglio.

The RS 5 Sportback handles at .97 G’s, while the Giulia Quadrifoglio pulls only .96 G’s of cornering force in a Car and Driver skidpad test.

Cargo Capacity

To make loading and unloading groceries and cargo easier when your hands are full, the RS 5 Sportback’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The Giulia Quadrifoglio doesn’t offer a power or hands-free opening trunk.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Audi service is better than Alfa Romeo. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 64% lower rating, Alfa Romeo is ranked 32nd.

Ergonomics

The RS 5 Sportback offers an optional heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Giulia Quadrifoglio doesn’t offer a heads-up display.

If the windows are left open on the RS 5 Sportback 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 also lower the windows the same way. The driver of the Giulia Quadrifoglio can only operate the windows from inside the vehicle, with the ignition on.

The RS 5 Sportback’s LED headlights produce a white, bright light using less electricity than the Giulia Quadrifoglio’s xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

When the RS 5 Sportback is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Giulia Quadrifoglio’s mirror doesn’t automatically adjust for backing.

Optional air-conditioned seats in the RS 5 Sportback keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Giulia Quadrifoglio doesn’t offer air-conditioned seats.

The RS 5 Sportback has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Giulia Quadrifoglio.

The RS 5 Sportback’s optional 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 Giulia Quadrifoglio doesn’t offer an automated parking system.
