For enhanced safety, the front and rear seat shoulder belts of the Genesis G80 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 doesn’t offer pretensioners for the rear seat belts.

The G80’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 and rear seat shoulder belts of the Genesis G80 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 G80 has standard Anti-Whiplash Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Anti-Whiplash Front Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Giulia doesn’t offer a whiplash protection system.

The G80’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.

The G80 has standard Connected Care, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Giulia doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the G80 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 and rear parking sensors.

The Genesis G80 weighs 559 to 1195 pounds more than the Alfa Romeo Giulia. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, with its optional front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the G80 its highest rating: “Top Pick Plus” for 2018, a rating granted to only 28 vehicles tested by the IIHS. The Giulia was last qualified as only a “Top Pick” in 2017.


The G80 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The Giulia’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G80 6 years and 50,000 miles longer than Alfa Romeo covers the Giulia. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Giulia ends after only 4 years or 50,000 miles.

The G80’s corrosion warranty is 3 years longer than the Giulia’s (7 vs. 4 years).

Genesis pays for scheduled maintenance on the G80 for 2 years and 26000 miles longer than Alfa Romeo pays for maintenance for the Giulia (3/36,000 vs. 1/10,000).

There are over 2 times as many Genesis dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the G80’s warranty.


A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the G80’s reliability 50 points higher than the Giulia.

J.D. Power and Associates rated the G80 second among midsize premium cars in their 2018 Initial Quality Study. The Giulia isn’t in the top three in its category.


The G80 3.8’s standard 3.8 DOHC V6 produces 31 more horsepower (311 vs. 280) than the Giulia’s 2.0 turbo 4 cyl. The G80 3.3T Sport’s standard 3.3 turbo V6 produces 85 more horsepower (365 vs. 280) and 70 lbs.-ft. more torque (376 vs. 306) than the Giulia’s 2.0 turbo 4 cyl. The G80 5.0’s standard 5.0 DOHC V8 produces 140 more horsepower (420 vs. 280) and 77 lbs.-ft. more torque (383 vs. 306) than the Giulia’s 2.0 turbo 4 cyl.

Consumer Reports

Tires and Wheels

For better traction, the G80 has larger standard tires than the Giulia (245/45R18 vs. 225/50R17). The G80’s optional tires are larger than the largest tires available on the Giulia (F:245/40R19 & R:275/35R19 vs. F:225/40R19 & R:255/35R19).

The G80 3.8’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Giulia’s standard 50 series tires.

For better ride, handling and brake cooling the G80 3.8 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Giulia.

The G80 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 Giulia; 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.

Suspension and Handling

For a smoother ride and more stable handling, the G80’s wheelbase is 7.5 inches longer than on the Giulia (118.5 inches vs. 111 inches).

For better handling and stability, the average track (width between the wheels) on the G80 is 2.6 inches wider in the front and .9 inches wider in the rear than the track on the Giulia.

The G80 5.0 handles at .88 G’s, while the Giulia Ti Q4 pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The G80 3.8 AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the Giulia Ti (26.2 seconds @ .69 average G’s vs. 27.1 seconds @ .66 average G’s).

For better maneuverability, the G80’s turning circle is 1.3 feet tighter than the Giulia’s (36.2 feet vs. 37.5 feet). The G80’s turning circle is .1 feet tighter than the Giulia’s (37.4 feet vs. 37.5 feet).


As tested by Car and Driver while at idle, the interior of the G80 5.0 is quieter than the Giulia Ti (39 vs. 41 dB).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the G80 a Large car, while the Giulia is rated a Mid-size.

The G80 has 12.3 cubic feet more passenger volume than the Giulia (107.7 vs. 95.4).

The G80 has 2.5 inches more front headroom, 3.3 inches more front legroom, 2.2 inches more front shoulder room, .6 inches more rear headroom and 3.5 inches more rear shoulder room than the Giulia.

Cargo Capacity

The G80 has a much larger trunk than the Giulia (15.3 vs. 12 cubic feet).

With its sedan body style, valet key and remote trunk release lockout, the G80 offers cargo security. The Giulia’s non-lockable remote release defeats cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the G80. The Giulia doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier when your hands are full, just waiting momentarily behind the back bumper can open the G80’s trunk, leaving your hands completely free. The G80 also offers an optional power trunk, which opens and closes automatically by pressing a button. The Giulia doesn’t offer a power or hands-free opening trunk.


The G80 offers an optional heads-up display that projects speed and other key instrumentation 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.

The Proximity Key standard on the G80 allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Alfa Romeo Giulia’s Keyless-Go doesn’t unlock the trunk.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The G80 3.8 AWD offers available headlight washers to keep headlight output high. The Giulia doesn’t offer headlight washers.

A power rear sunshade is optional in the G80 to help block heat and glare for the rear passengers. The Giulia doesn’t offer a rear sunshade.

When the G80 is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Giulia’s mirrors don’t automatically adjust for backing.

Optional air conditioned seats in the G80 keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Giulia doesn’t offer an air-conditioned driver’s seat.


Consumer Reports® recommends the Genesis G80, based on reliability, safety and performance. The Alfa Romeo Giulia isn't recommended.

The Genesis G80 outsold the Alfa Romeo Giulia by 82% during 2017.
