Both the Giulia and the C-Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Giulia the rating of “Top Pick” for 2018, a rating granted to only 100 vehicles tested by the IIHS. The C-Class Sedan was a “Top Pick” for 2017, but no longer qualifies under the tighter 2018 guidelines.


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

The C-Class Sedan’s redline is at 6500 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The Giulia has a 5500 RPM redline.

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 C-Class Sedan’s battery is in the hot engine compartment.


The Giulia’s 2.0 turbo 4 cyl. produces 25 more horsepower (280 vs. 255) and 33 lbs.-ft. more torque (306 vs. 273) than the C 300 Sedan’s standard 2.0 turbo 4 cyl.

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Alfa Romeo Giulia uses regular unleaded gasoline (premium recommended for maximum performance). The C-Class Sedan requires premium, which can cost 20 to 55 cents more per gallon.

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. Run-flat tires aren’t available on some tire packages on the C-Class Sedan.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the Giulia is 3 inches wider in the rear than the average track on the C-Class Sedan.

The Giulia’s front to rear weight distribution is more even (50% to 50%) than the C-Class Sedan’s (53% to 47%). This gives the Giulia more stable handling and braking.

The Giulia Ti Q4 executes Motor Trend’s “Figure Eight” maneuver quicker than the C 300 Sedan 4MATIC (25.6 seconds @ .71 average G’s vs. 26.3 seconds @ .7 average G’s).

Passenger Space

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

The Giulia has 5.4 cubic feet more passenger volume than the C-Class Sedan (95.4 vs. 90).

The Giulia has 1.5 inches more front headroom, .7 inches more front legroom, .8 inches more front shoulder room and .5 inches more rear headroom than the C-Class Sedan.

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 C-Class Sedan’s liftover is 28 inches.


Heated windshield washer nozzles are optional on the Giulia to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The C-Class Sedan doesn’t offer heated windshield washer nozzles.

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 C-Class Sedan’s headlights are rated “Poor.”

Both the Giulia and the C-Class 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 C-Class Sedan.


Motor Trend performed a comparison test in its June 2017 issue and they ranked the Alfa Romeo Giulia first. They ranked the Mercedes C 300 Sedan third.

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

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