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 A4 doesn’t offer run-flat tires.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the Giulia is 2.7 inches wider in the rear than on the A4.

The Giulia’s front to rear weight distribution is more even (50% to 50%) than the A4’s (56% to 44%). This gives the Giulia more stable handling and braking.

The Giulia Ti Q4 executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the A4 Premium (25.6 seconds @ .71 average G’s vs. 27.2 seconds @ .64 average G’s).

For better maneuverability, the Giulia’s turning circle is .6 feet tighter than the A4’s (37.5 feet vs. 38.1 feet).


The Giulia is 3.5 inches shorter than the A4, making the Giulia easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver while at idle, the interior of the Giulia Ti is quieter than the A4 Prestige Quattro (41 vs. 42 dB).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Giulia a Mid-size car, while the A4 is rated a Compact.

The Giulia has 3.4 cubic feet more passenger volume than the A4 (95.4 vs. 92).

The Giulia has 1.1 inches more front legroom, .2 inches more front shoulder room and .2 inches more rear headroom than the A4.

Cargo Capacity

A low lift-over trunk design makes loading and unloading the Giulia easier. The Giulia’s trunk lift-over height is 25.8 inches, while the A4’s liftover is 26.9 inches.


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 A4 doesn’t offer a remote starting 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 A4 doesn’t offer an easy entry system.

Consumer Reports rated the Giulia’s headlight performance “Good,” a higher rating than the A4’s headlights, which were rated “Poor.”

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 A4’s headlights are rated “Acceptable” to “Marginal.”

The A4’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Giulia’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.


Motor Trend performed a comparison test in its June 2017 issue and the Alfa Romeo Giulia won out over the Audi A4 Premium Plus Quattro.

The Giulia was chosen as one of Car and Driver’s “Top Ten” in 2018. The A4 has never been a Car and Driver “Top Ten” pick.

Motor Trend selected the Giulia as their 2018 Car of the Year. The A4 has never been chosen.
