Safety

For enhanced safety, the front and rear seat shoulder belts of the Audi A5 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 doesn’t offer pretensioners for the rear seat belts.

The A5 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 doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Audi A5 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 doesn’t offer height-adjustable seat belts.

The A5 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 doesn’t offer a whiplash protection system.

The A5 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 Giulia 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A5 Sportback. But it costs extra on the Giulia.

The A5 Sportback Prestige has a standard Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The Giulia 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 A5 Sportback Premium Plus/Prestige has a 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 Giulia 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 A5 Sportback and the Giulia 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, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems and rear cross-path warning.

Warranty

The A5 Sportback’s corrosion warranty is 8 years longer than the Giulia’s (12 vs. 4 years).

There are over 75 percent more Audi dealers than there are Alfa Romeo dealers, which makes it much easier should you ever need service under the A5 Sportback’s warranty.

Reliability

The Audi A5 Sportback’s engine uses a cast iron block for durability, while the Giulia’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

Fuel Economy and Range

On the EPA test cycle the A5 Sportback gets better fuel mileage than the Giulia Q4 (23 city/34 hwy vs. 23 city/31 hwy).

Regenerative brakes improve the A5 Sportback’s fuel efficiency by converting inertia back into energy instead of wasting it. The Giulia doesn’t offer a regenerative braking system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A5 Sportback higher (5 out of 10) than the Alfa Romeo Giulia (3). This means the A5 Sportback produces up to 16.5 pounds less smog-producing pollutants than the Giulia every 15,000 miles.

Transmission

The A5 Sportback 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 Giulia doesn’t offer an SMG or a conventional manual transmission.

The A5 Sportback’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 Giulia doesn’t offer launch control.

Brakes and Stopping

For better stopping power the A5 Sportback’s brake rotors are larger than those on the Giulia:

The A5 Sportback’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Giulia are solid, not vented.

The A5 Sportback stops much shorter than the Giulia:

Car and Driver

Tires and Wheels

For better traction, the A5 Sportback has larger standard tires than the Giulia (245/40R18 vs. 225/50R17). The A5 Sportback’s optional tires are larger than the largest tires available on the Giulia (255/35R19 vs. 225/40R19).

The A5 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 Giulia’s standard 50 series tires. The A5 Sportback’s optional tires have a lower 35 series profile than the Giulia Ti’s optional 40 series front tires.

For better ride, handling and brake cooling the A5 Sportback has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Giulia.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the A5 Sportback is 1.2 inches wider in the front than on the Giulia.

The A5 Sportback Prestige handles at .94 G’s, while the Giulia Ti Q4 pulls only .79 G’s of cornering force in a Car and Driver skidpad test.

Chassis

As tested by Car and Driver, the interior of the A5 Sportback Prestige is quieter than the Giulia Ti:

Passenger Space

The A5 Sportback has .8 inches more front headroom and .9 inches more rear shoulder room than the Giulia.

Cargo Capacity

The A5 Sportback has a much larger trunk than the Giulia (21.8 vs. 12 cubic feet).

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the A5 Sportback. The Giulia doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier, especially for short adults, the A5 Sportback has a standard power liftgate, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The Giulia doesn’t offer a power trunk.

Ergonomics

The A5 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 Giulia doesn’t offer a heads-up display.

If the windows are left open on the A5 Sportback the driver can close them all at the outside door handle. On a hot day the driver can also lower the windows the same way. The driver of the Giulia can only operate the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are standard on the A5 Sportback to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. Heated windshield washer nozzles cost extra on the Giulia.

When the A5 Sportback with available tilt-down mirrors 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’s mirror doesn’t automatically adjust for backing.

Optional air-conditioned seats in the A5 Sportback Premium Plus/Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Giulia doesn’t offer air-conditioned seats.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi A5 Premium Plus/Prestige has a standard wireless phone charging system (Qi) in the center console. The Giulia doesn’t offer wireless personal charging.

The A5 Sportback 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 Giulia doesn’t offer an automated parking system.

Model Availability

The Audi A5 comes in coupe, convertible and four door hatchback bodystyles; the Alfa Romeo Giulia isn’t available as a coupe or convertible.

Recommendations

The Audi A5/S5 outsold the Alfa Romeo Giulia by almost three to one during the 2018 model year.
