Both the Giulia and the A3 Sedan 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 all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, front parking sensors and rear cross-path warning.


The engine in the Giulia has a single overhead cam for simplicity. The engines in the A3 Sedan have dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.

The battery on the Giulia is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Giulia’s battery 20 to 30 degrees cooler, its life is increased by years. The A3 Sedan’s battery is in the hot engine compartment.


The Giulia’s 2.0 turbo 4 cyl. produces 96 more horsepower (280 vs. 184) and 85 lbs.-ft. more torque (306 vs. 221) than the A3 Sedan 40 TSFI’s standard 2.0 turbo 4 cyl. The Giulia’s 2.0 turbo 4 cyl. produces 52 more horsepower (280 vs. 228) and 48 lbs.-ft. more torque (306 vs. 258) than the A3 Sedan 45 TSFI’s optional 2.0 turbo 4 cyl.

Fuel Economy and Range

On the EPA test cycle the Giulia Q4 gets better fuel mileage than the A3 Quattro Sedan (23 city/31 hwy vs. 22 city/30 hwy).

In heavy traffic or at stoplights the Giulia’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 A3 Sedan doesn’t offer an automatic engine start/stop system.

The Giulia has 2.1 gallons more fuel capacity than the A3 Sedan 40 TSFI’s standard fuel tank (15.3 vs. 13.2 gallons), for longer range between fill-ups.


An eight-speed automatic is standard on the Alfa Romeo Giulia, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A3 Sedan.

Brakes and Stopping

For better stopping power the Giulia’s brake rotors are larger than those on the A3 Sedan:

Tires and Wheels

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the Giulia can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The A3 Sedan doesn’t offer run-flat tires.

Suspension and Handling

The Giulia offers an optional 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 A3 Sedan’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Giulia’s wheelbase is 7.2 inches longer than on the A3 Sedan (111 inches vs. 103.8 inches).

For better handling and stability, the track (width between the wheels) on the Giulia is .1 inches wider in the front and 3.8 inches wider in the rear than on the A3 Sedan.

The Giulia’s front to rear weight distribution is more even (50% to 50%) than the A3 Sedan’s (58.1% to 41.9%). This gives the Giulia more stable handling and braking.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Giulia a Mid-size car, while the A3 Sedan is rated a Subcompact.

The Giulia has 9.4 cubic feet more passenger volume than the A3 Sedan (95.4 vs. 86).

The Giulia has 2.1 inches more front headroom, 1.2 inches more front legroom, 1.3 inches more front shoulder room, 1.5 inches more rear headroom and .6 inches more rear shoulder room than the A3 Sedan.

Servicing Ease

The engine in the Giulia is mounted longitudinally (North-South), instead of sideways, as in the A3 Sedan. This makes it easier to service and maintain, because the accessory belts are in front.

The Giulia has a maintenance free battery for long life without checking the battery’s water level. The A3 Sedan doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.


The Giulia has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The A3 Sedan doesn’t offer a remote starting system.

When three different drivers share the Giulia, the memory seats and mirrors make it convenient for all three. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The A3 Sedan doesn’t offer a memory system.

The Giulia’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The A3 Sedan doesn’t offer an easy entry system.

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 Giulia’s available headlights were rated “Good” by the IIHS, while the A3 Sedan’s headlights are rated “Acceptable” to “Poor.”

To help drivers see further while navigating curves, the Giulia offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The A3 Sedan doesn’t offer cornering lights.

Both the Giulia and the A3 Sedan offer optional heated front seats. The Giulia also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the A3 Sedan.

On extremely cold winter days, the Giulia’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The A3 Sedan doesn’t offer a heated steering wheel.


The Giulia was chosen as one of Car and Driver’s “Top Ten” in 2018. The A3 Sedan has never been a Car and Driver “Top Ten” pick.

Motor Trend selected the Giulia as their 2018 Car of the Year. The A3 Sedan has never been chosen.
