For enhanced safety, the front and rear seat shoulder belts of the Audi S3 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.
The S3 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.

Both the S3 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, rearview cameras, available lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.
For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, with its optional front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the S3 the rating of “Top Pick” for 2019, a rating granted to only 106 vehicles tested by the IIHS.

To lower fuel costs and make buying fuel easier, the Audi S3 uses regular unleaded gasoline (premium recommended for maximum performance). The Giulia Quadrifoglio requires premium, which can cost 20 to 55 cents more per gallon.
The S3 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 Quadrifoglio doesn’t offer an SMG or a conventional manual transmission.
The S3’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 Quadrifoglio doesn’t offer launch control.
The S3 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.
For better maneuverability, the S3’s turning circle is 1.4 feet tighter than the Giulia Quadrifoglio’s (36.1 feet vs. 37.5 feet).
The Audi S3 may be more efficient, handle and accelerate better because it weighs about 300 pounds less than the Alfa Romeo Giulia Quadrifoglio.
The S3 is 6.8 inches shorter than the Giulia Quadrifoglio, making the S3 easier to handle, maneuver and park in tight spaces.
If the windows are left open on the S3 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 lower the windows from a distance using the keyless remote. The driver of the Giulia Quadrifoglio can only operate the windows from inside the vehicle, with the ignition on.
To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi S3 Premium Plus has a standard wireless phone charging system (Qi) in the center console. The Giulia Quadrifoglio doesn’t offer wireless personal charging.
The S3 Premium Plus’ 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.
