For enhanced safety, the front and rear seat shoulder belts of the Mercedes C-Class Sedan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Alfa Romeo Giulia doesn’t offer pretensioners for the rear seat belts.

The C-Class Sedan’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 Mercedes C-Class Sedan 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 C-Class Sedan offers an optional Surround View System 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.

Both the C-Class Sedan 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, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, with its optional front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the C-Class Sedan its highest rating: “Top Pick Plus” for 2019, a rating granted to only 54 vehicles tested by the IIHS. The Giulia has not been fully tested, yet.

The C-Class Sedan’s corrosion warranty is 1 year longer than the Giulia’s (5 vs. 4 years).

There are over 2 times as many Mercedes dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the C-Class Sedan’s warranty.

The C-Class Sedan’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Giulia doesn’t offer drift compensation steering.

The C 300 Sedan handles at .91 G’s, while the Giulia Ti Q4 pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The C 300 Sedan executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the Giulia Ti (25.7 seconds @ .71 average G’s vs. 27.1 seconds @ .66 average G’s).

For better maneuverability, the C-Class Sedan’s turning circle is .7 feet tighter than the Giulia’s (36.8 feet vs. 37.5 feet).

The front grille of the C-Class Sedan uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Giulia doesn’t offer active grille shutters.

The C-Class Sedan has a larger trunk than the Giulia (12.6 vs. 12 cubic feet).

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the C-Class offers cargo security. The Giulia’s non-lockable remote release defeats cargo security.

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

Unlike the driver-only memory seat and mirrors in the Giulia, the C-Class Sedan offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The C-Class Sedan offers an optional heads-up display that projects speed 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 doesn’t offer a heads-up display.

If the windows are left open on the C-Class Sedan 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 can only operate the windows from inside the vehicle, with the ignition on.

Keyless-Go standard on the C-Class Sedan allows you to unlock the doors, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Alfa Romeo Giulia’s Keyless-Go doesn’t unlock the trunk.

A power rear sunshade is optional in the C-Class Sedan to help block heat and glare for the rear passengers. The Giulia doesn’t offer a rear sunshade.

When the C-Class Sedan 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 C-Class Sedan 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.

The C-Class Sedan’s optional Active Parking Assist can parallel park or back into a parking spot by itself, stopping and changing direction automatically. The Giulia doesn’t offer an automated parking system.
