To help make backing safer, the Giulia’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The C-Class Sedan doesn’t offer a cross-path warning system.
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 and front parking sensors.
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 Giulia’s 2.0 turbo 4 cyl. produces 39 more horsepower (280 vs. 241) and 33 lbs.-ft. more torque (306 vs. 273) than the C300 Sedan’s standard 2.0 turbo 4 cyl.
The Giulia 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 C-Class Sedan, it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some models of the C-Class Sedan don’t even offer run-flats.
For better handling and stability, the track (width between the wheels) on the Giulia is 3 inches wider in the rear than on the C-Class Sedan.
