Safety

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 A-Class doesn’t offer a cross-path warning system.

Both the Giulia and the A-Class have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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.

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 A-Class has not been tested, yet.

Reliability

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

The A-Class’ 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.

Engine

The Giulia’s 2.0 turbo 4 cyl. produces 92 more horsepower (280 vs. 188) and 85 lbs.-ft. more torque (306 vs. 221) than the A-Class’ 2.0 turbo 4 cyl.

As tested in Car and Driver the Alfa Romeo Giulia is faster than the Mercedes A 220:

Fuel Economy and Range

The Giulia has 1.8 gallons more fuel capacity than the A-Class (15.3 vs. 13.5 gallons), for longer range between fill-ups.

Transmission

An eight-speed automatic is standard on the Alfa Romeo Giulia, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A-Class.

Brakes and Stopping

For better stopping power the Giulia’s brake rotors are larger than those on the A-Class:

Tires and Wheels

For better traction, the Giulia has larger standard tires than the A-Class (225/50R17 vs. 205/55R17). The Giulia Ti’s optional tires are larger than the largest tires available on the A-Class (F:225/40R19 & R:255/35R19 vs. 205/55R17).

The Giulia’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the A-Class’ standard 55 series tires. The Giulia Ti’s optional 225/40R19 front and 255/35R19 rear tires have a lower 40 series front and 35 series rear profile than the A-Class’ 55 series tires.

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 A-Class.

Suspension and Handling

For a smoother ride and more stable handling, the Giulia’s wheelbase is 3.6 inches longer than on the A-Class (111 inches vs. 107.4 inches).

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

Passenger Space

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

The Giulia has 2.4 cubic feet more passenger volume than the A-Class (95.4 vs. 93).

The Giulia has .6 inches more front legroom, 1 inch more front shoulder room, .4 inches more rear headroom and 1.2 inches more rear legroom than the A-Class.

Cargo Capacity

The Giulia has a much larger trunk than the A-Class (12 vs. 8.6 cubic feet).

Servicing Ease

The engine in the Giulia is mounted longitudinally (North-South), instead of sideways, as in the A-Class. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

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 A-Class doesn’t offer heated windshield washer nozzles.

Recommendations

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

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