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 Infiniti Q50 doesn’t offer pretensioners for its rear seat belts.

Both the G80 and Q50 have child safety locks to prevent children from opening the rear doors. The G80 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Q50’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the G80 are reminded to check the back seat if they opened the rear door before starting out. The Q50 doesn’t offer a back seat reminder.

The Genesis G80 has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Q50 doesn’t offer knee airbags.

The G80 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Q50 doesn’t offer front seat center airbags.

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 Q50 doesn’t offer a whiplash protection system.

With its standard Forward Collision-Avoidance Assist with Pedestrian Detection, the Genesis G80 is better at preventing collisions with pedestrians than the Infiniti Q50, according to the Insurance Institute for Highway Safety:

	G80	Q50
Overall Evaluation	ACCEPTABLE	POOR
	Crossing Child - DAY
12 MPH	AVOIDED	No Slowing
25 MPH	AVOIDED	No Slowing
	Crossing Adult - NIGHT
12 MPH Brights	AVOIDED	No Slowing
12 MPH Low beams	-11 MPH	No Slowing
25 MPH Brights	AVOIDED	No Slowing
25 MPH Low beams	-22 MPH	No Slowing
	Parallel Adult - NIGHT
25 MPH Brights	AVOIDED	No Slowing
25 MPH Low beams	AVOIDED	No Slowing
37 MPH Brights	-20 MPH	No Slowing
Warning Issued-Brights	1.1 sec	No Warning
37 MPH Low beams	-20 MPH	No Slowing
Warning Issued-Low beams	1.1 sec	No Warning

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the G80. But it costs extra on the Q50.

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 Q50 doesn’t offer a driver alert monitor.

Both the G80 and the Q50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The Genesis G80 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned an “Acceptable” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and an “Acceptable” score in the revised pedestrian crash prevention test. The Q50 is not even a standard “Top Safety Pick” for 2024.

Warranty

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 Q50’s 4-year/60,000-mile basic warranty expires 1 year sooner.

Genesis’ powertrain warranty covers the G80 4 years and 30,000 miles longer than Infiniti covers the Q50. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Q50 ends after only 6 years or 70,000 miles.

There are over 19 percent more Genesis dealers than there are Infiniti dealers, which makes it easier should you ever need service under the G80’s warranty.

Reliability

The battery on the G80 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the G80’s battery 20 to 30 degrees cooler, its life is increased by years. The Q50’s battery is in the hot engine compartment.

J.D. Power and Associates rated the G80 first among upper midsize premium cars in their 2024 Initial Quality Study. The Q50 isn’t in the top three in its category.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Genesis vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Genesis above average in initial quality. With 3 more problems per 100 vehicles, Infiniti is rated lower.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Genesis vehicles are more reliable than Infiniti With 19 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Genesis higher than Infiniti.

Engine

The G80 2.5T’s standard 2.5 turbo 4-cylinder produces 16 lbs.-ft. more torque (311 vs. 295) than the Q50’s standard 3.0 turbo V6. The G80 3.5T’s standard 3.5 turbo V6 produces 41 lbs.-ft. more torque (391 vs. 350) than the Q50 Red Sport 400’s standard 3.0 turbo V6.

Fuel Economy and Range

On the EPA test cycle the G80 gets better mileage than the Q50:

			MPG
G80
	AWD	2.5 turbo 4-cyl.	22 city/30 hwy
Q50
	RWD	3.0 turbo V6	20 city/29 hwy
		Red Sport 400 3.0 turbo V6	20 city/26 hwy
	AWD	3.0 turbo V6	19 city/27 hwy
		Red Sport 400 3.0 turbo V6	19 city/26 hwy

In heavy traffic or at stoplights the G80’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Q50 doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Genesis G80 higher (5 out of 10) than the Infiniti Q50 (3). This means the G80 produces up to 16.5 pounds less smog-producing pollutants than the Q50 every 15,000 miles.

Transmission

An eight-speed automatic is standard on the Genesis G80, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Q50.

Brakes and Stopping

For better stopping power the G80’s brake rotors are larger than those on the Q50:

	G80 2.5T	G80 3.5T	Q50	Q50 Red Sport 400
Front Rotors	13.6 inches	14.2 inches	12.6 inches	14 inches
Rear Rotors	12.8 inches	13.6 inches	12.1 inches	13.8 inches

The G80 stops shorter than the Q50:

	G80	Q50
70 to 0 MPH	160 feet	165 feet	Car and Driver

Tires and Wheels

For better traction, the G80 has larger standard tires than the Q50 (245/50R18 vs. 225/50R18).

For better ride, handling and brake cooling the G80 3.5T Sport Prestige offers optional 20-inch wheels. The Q50’s largest wheels are only 19-inches.

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 Q50; 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

The G80 has standard front and rear gas-charged shocks for better control over choppy roads. The Q50’s suspension doesn’t offer gas-charged shocks.

For a smoother ride and more stable handling, the G80’s wheelbase is 6.3 inches longer than on the Q50 (118.5 inches vs. 112.2 inches).

For better handling and stability, the average track (width between the wheels) on the G80 is 3.6 inches wider in the front and 3.4 inches wider in the rear than the average track on the Q50.

The G80’s front to rear weight distribution is more even (52% to 48%) than the Q50’s (55.9% to 44.1%). This gives the G80 more stable handling and braking.

The G80 handles at .91 G’s, while the Q50 Red Sport 400 pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

Passenger Space

The G80 has 3.8 cubic feet more passenger volume than the Q50 (103.8 vs. 100).

The G80 has 1.6 inches more front headroom, 1.6 inches more front shoulder room, 1.4 inches more rear headroom, 3.6 inches more rear legroom and 1 inch more rear shoulder room than the Q50.

Cargo Capacity

To make loading and unloading groceries and cargo easier when your hands are full, the G80’s trunk can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The G80 also offers an optional power trunk, which opens and closes automatically by pressing a button. The Q50 doesn’t offer a power or hands-free opening trunk.

Ergonomics

The G80 3.5T Sport Prestige has a standard heads-up display that projects speed, warning 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 Q50 doesn’t offer a heads-up display.

The G80’s power parking brake sets with one touch and releases with one touch or automatically. The Q50’s parking brake has to be released manually.

The power windows standard on both the G80 and the Q50 have locks to prevent small children from operating them. When the lock on the G80 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Q50 prevents the driver from operating the other windows just as it does the other passengers.

Consumer Reports rated the G80’s headlight performance “Very Good,” a higher rating than the Q50’s headlights, which were rated “Good.”

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 G80’s headlights were rated “Acceptable” by the IIHS, while the Q50’s headlights are rated “Marginal.”

A power rear sunshade and manual rear side window sunshades are standard in the G80 Advanced/Sport/Sport Prestige to help block heat and glare for the rear passengers. The Q50 doesn’t offer a rear or rear side window sunshades.

Both the G80 and the Q50 have standard heated front seats. The G80 also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Q50.

Standard air-conditioned seats in the G80 Advanced/Sport/Sport Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q50 doesn’t offer air-conditioned seats.

The G80 Sport/Sport Prestige has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Q50.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Genesis G80 Sport/Sport Prestige has a standard wireless phone charging system (Qi) in the front center console. The Q50 doesn’t offer wireless personal charging.

The G80 Sport Prestige’s Smart Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Q50 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the G80 owner. The Complete Car Cost Guide estimates that insurance for the G80 will cost $1620 less than the Q50 over a five-year period.

The G80 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the G80 will retain 46.32% to 47.24% of its original price after five years, while the Q50 only retains 45.32% to 45.77%.
