Safety Comparison

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.

The C-Class Sedan’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Giulia doesn’t offer a driver alert monitor.

Both the C-Class Sedan and the Giulia have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, lane departure warning systems and blind spot warning systems.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the C-Class Sedan the rating of “Top Pick” for 2017, a rating granted to only 113 vehicles tested by the IIHS. The Giulia has not been tested, yet.

Warranty Comparison

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.

Engine Comparison

The AMG C43 Sedan’s standard 3.0 turbo V6 produces 82 more horsepower (362 vs. 280) and 78 lbs.-ft. more torque (384 vs. 306) than the Giulia’s 2.0 turbo 4 cyl.

Tires and Wheels Comparison

The C-Class Sedan’s optional 255/35R19 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Giulia Ti’s optional 40 series tires.

Suspension and Handling Comparison

The C-Class Sedan has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The C-Class Sedan’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Giulia doesn’t offer a load leveling suspension.

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.

For better handling and stability, the track (width between the wheels) on the C-Class Sedan is 1.2 inches wider in the front than on the Giulia.

The C300 Sedan handles at .91 G’s, while the Giulia pulls only .84 G’s of cornering force in a Motor Trend skidpad test.

The C300 Sedan executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the Giulia (25.7 seconds @ .71 average G’s vs. 26.8 seconds @ .67 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).

Chassis Comparison

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.

Passenger Space Comparison

The C-Class Sedan has .1 inches more rear legroom and 1.4 inches more rear shoulder room than the Giulia.

Cargo Capacity Comparison

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

The C-Class Sedan’s standard rear seats fold to accommodate long and bulky cargo. The Giulia doesn’t offer folding rear seats.

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

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.

Ergonomics Comparison

Unlike the driver-only memory system 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.

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 has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable. The Giulia doesn’t offer a rear seat center armrest.

The C-Class Sedan’s optional Active Parking 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.

Recommendations Comparison

The C-Class Sedan was chosen as one of Automobile Magazine’s “All Stars” in 2015. The Giulia has never been an “All Star.”
