For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG E-Class Sedan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Alfa Romeo Giulia Quadrifoglio doesn’t offer pretensioners for its rear seat belts.

The AMG E-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 Quadrifoglio doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Mercedes AMG E-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 Quadrifoglio doesn’t offer height-adjustable seat belts.

Over 200 people are killed each year when backed over by motor vehicles. The AMG E-Class Sedan has a standard Maneuvering Brake Function that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Giulia Quadrifoglio doesn’t offer backup collision prevention brakes.

The AMG E-Class Sedan has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Giulia Quadrifoglio doesn’t offer all-wheel drive.

The AMG E-Class Sedan has a standard Surround View System to allow the driver to see objects all around the vehicle on a screen. The Giulia Quadrifoglio 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 AMG E-Class Sedan and Giulia Quadrifoglio have rear cross-traffic warning, but the AMG E-Class Sedan has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Giulia Quadrifoglio’s Rear Cross-Path Detection doesn’t automatically brake.

Both the AMG E-Class Sedan and the Giulia Quadrifoglio 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, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.

The Mercedes AMG E-Class Sedan weighs 570 to 781 pounds more than the Alfa Romeo Giulia Quadrifoglio. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

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, its standard vehicle-to-vehicle front crash prevention system, with its available vehicle-to-pedestrian front crash prevention system, and its headlight’s “Good” to “Acceptable” rating, the Insurance Institute for Highway Safety grants the AMG E-Class Sedan the rating of “Top Safety Pick” for 2022, a rating granted to only 174 vehicles tested by the IIHS. The Giulia Quadrifoglio has not been fully tested, yet.

Warranty

There are almost 3 times as many Mercedes dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the AMG E-Class Sedan’s warranty.

Reliability

To reliably start during all conditions and help handle large electrical loads, the AMG E-Class Sedan has a standard 850-amp battery. The Giulia Quadrifoglio’s 525-amp battery isn’t as powerful.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Alfa Romeo vehicles. With 22 fewer problems per 100 vehicles, JD Power ranks Mercedes higher than Alfa Romeo.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Alfa Romeo With 50 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Mercedes higher than Alfa Romeo.

Engine

The AMG E 63 S’ standard 4.0 turbo V8 hybrid produces 98 more horsepower (603 vs. 505) and 184 lbs.-ft. more torque (627 vs. 443) than the Giulia Quadrifoglio’s 2.9 turbo V6.

As tested in Car and Driver the AMG E 63 S 4.0 turbo V8 hybrid is faster than the Alfa Romeo Giulia Quadrifoglio:

	AMG E-Class Sedan	Giulia Quadrifoglio
Zero to 30 MPH	1.2 sec	1.6 sec
Zero to 60 MPH	3 sec	3.6 sec
Zero to 100 MPH	7 sec	8.1 sec
5 to 60 MPH Rolling Start	3.9 sec	4.2 sec
Passing 30 to 50 MPH	2.3 sec	2.5 sec
Passing 50 to 70 MPH	2.7 sec	2.8 sec
Quarter Mile	11.1 sec	11.9 sec
Speed in 1/4 Mile	126 MPH	121 MPH

Fuel Economy and Range

On the EPA test cycle the AMG E 53 3.0 turbo 6-cylinder Hybrid gets better fuel mileage than the Giulia Quadrifoglio (21 city/29 hwy vs. 17 city/25 hwy).

Regenerative brakes improve the AMG E-Class Sedan E 53’s fuel efficiency by converting inertia back into energy instead of wasting it. The Giulia Quadrifoglio doesn’t offer a regenerative braking system.

The AMG E-Class Sedan has 5.8 gallons more fuel capacity than the Giulia Quadrifoglio (21.1 vs. 15.3 gallons), for longer range between fill-ups.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG E-Class Sedan higher (5 to 6 out of 10) than the Alfa Romeo Giulia Quadrifoglio (3). This means the AMG E-Class Sedan produces up to 23.4 pounds less smog-producing pollutants than the Giulia Quadrifoglio every 15,000 miles.

Transmission

A nine-speed automatic (SMG) is standard on the Mercedes AMG E-Class Sedan, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Giulia Quadrifoglio.

The AMG E-Class Sedan offers an available sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Giulia Quadrifoglio doesn’t offer an SMG or a conventional manual transmission.

The AMG E-Class Sedan 63 S’ launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Giulia Quadrifoglio doesn’t offer launch control.

Brakes and Stopping

For better stopping power the AMG E-Class Sedan’s brake rotors are larger than those on the Giulia Quadrifoglio:

	AMG E 53	AMG E 63 S CCB	Giulia Quadrifoglio
Front Rotors	14.6 inches	15.8 inches	14.2 inches
Rear Rotors	14.2 inches	14.2 inches	13.8 inches

The AMG E-Class Sedan stops shorter than the Giulia Quadrifoglio:

	AMG E-Class Sedan	Giulia Quadrifoglio
70 to 0 MPH	155 feet	157 feet	Car and Driver

Tires and Wheels

For better traction, the AMG E 63 S’ tires are larger than the largest tires available on the Giulia Quadrifoglio (F:265/35R20 & R:295/30R20 vs. F:245/35R19 & R:285/30R19).

For better ride, handling and brake cooling the AMG E 53 offers optional 20-inch wheels. The Giulia Quadrifoglio’s largest wheels are only 19-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the AMG E-Class Sedan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Giulia Quadrifoglio doesn’t offer run-flat tires.

Suspension and Handling

The front and rear suspension of the AMG E-Class Sedan uses air springs for a smoother, controlled ride than the Giulia Quadrifoglio, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The AMG E-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 AMG E-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 Quadrifoglio doesn’t offer a load leveling suspension.

The AMG E-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 Quadrifoglio doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the AMG E-Class Sedan’s wheelbase is 4.7 inches longer than on the Giulia Quadrifoglio (115.7 inches vs. 111 inches).

For better handling and stability, the average track (width between the wheels) on the AMG E-Class Sedan is 3.3 inches wider in the front than the track on the Giulia Quadrifoglio.

The AMG E 63 S handles at 1.01 G’s, while the Giulia Quadrifoglio pulls only .96 G’s of cornering force in a Car and Driver skidpad test.

Chassis

As tested by Car and Driver, the interior of the AMG E 63 S is quieter than the Giulia Quadrifoglio:

	AMG E-Class Sedan	Giulia Quadrifoglio
At idle	42 dB	49 dB
70 MPH Cruising	73 dB	73 dB

Passenger Space

The AMG E-Class Sedan has 1.7 inches more front shoulder room, 1.1 inches more rear legroom and 3.5 inches more rear shoulder room than the Giulia Quadrifoglio.

Cargo Capacity

The AMG E-Class Sedan has a much larger trunk than the Giulia Quadrifoglio (13.1 vs. 12 cubic feet).

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

To make loading and unloading groceries and cargo easier when your hands are full, the AMG E-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 Quadrifoglio doesn’t offer a power or hands-free opening trunk.

Ergonomics

Unlike the driver-only memory seat and mirrors in the Giulia Quadrifoglio, the AMG E-Class Sedan has standard driver and 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 AMG E-Class Sedan offers an optional heads-up display that projects speed, tachometer 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 Quadrifoglio doesn’t offer a heads-up display.

If the windows are left open on the AMG E-Class Sedan the driver can close them all at the outside door handle or from a distance using the remote (remote must be aimed at door sensor). On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Giulia Quadrifoglio can only operate the windows from inside the vehicle, with the ignition on.

Heated windshield washer fluid is standard on the AMG E-Class Sedan to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Giulia Quadrifoglio doesn’t offer heated windshield washer fluid. Its standard heated washer nozzles will defrost the washer fluid but not the windshield.

The AMG E-Class Sedan’s LED headlights produce a white, bright light using less electricity than the Giulia Quadrifoglio’s xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

To better shield the driver and front passenger’s vision, the AMG E-Class Sedan has standard dual-element sun visors that can block glare from two directions simultaneously. The Giulia Quadrifoglio doesn’t offer secondary sun visors.

A power rear sunshade and manual rear side window sunshades are optional in the AMG E-Class Sedan to help block heat and glare for the rear passengers. The Giulia Quadrifoglio doesn’t offer a rear or rear side window sunshades.

When the AMG E-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 Quadrifoglio’s mirror doesn’t automatically adjust for backing.

Optional air-conditioned seats in the AMG E-Class Sedan keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Giulia Quadrifoglio doesn’t offer air-conditioned seats.

The AMG E-Class Sedan has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel isn’t available on the Giulia Quadrifoglio w/Sparco Racing Seats.

The AMG E-Class Sedan offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Giulia Quadrifoglio.

The AMG E-Class Sedan offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Giulia Quadrifoglio doesn’t offer a house-current electrical outlet.

The AMG E-Class Sedan’s Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The Giulia Quadrifoglio doesn’t offer an automated parking system.

Model Availability

The Mercedes AMG E-Class comes in coupe, convertible and sedan bodystyles; the Alfa Romeo Giulia Quadrifoglio isn’t available as a coupe or convertible.

Economic Advantages

Insurance will cost less for the AMG E-Class Sedan owner. The Complete Car Cost Guide estimates that insurance for the AMG E-Class Sedan will cost $5840 less than the Giulia Quadrifoglio over a five-year period.

Recommendations
