The G90’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Panamera doesn’t offer pre-crash pretensioners.

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 G90 are reminded to check the back seat when a sensor determines the back seat is occupied. The Panamera doesn’t offer a back seat reminder.

The G90 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 Panamera doesn’t offer front seat center airbags.

The G90 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 Panamera doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The G90 offers an optional Parking Collision-Avoidance Assist-Reverse that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Panamera doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the G90. But it costs extra on the Panamera.

The G90 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Panamera’s blind spot costs extra.

To help make backing out of a parking space safer, the G90’s standard Rear Cross-Traffic Collision-Avoidance Assist uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engage the brakes. The Panamera doesn’t offer a rear cross-path warning system.

The G90’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 Panamera doesn’t offer a driver alert monitor.

Both the G90 and the Panamera have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, lane departure warning systems and rearview cameras.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the G90 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The Panamera has not been tested, yet.

Warranty

The G90 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The Panamera’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Genesis’ powertrain warranty covers the G90 6 years and 50,000 miles longer than Porsche covers the Panamera. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Panamera ends after only 4 years or 50,000 miles.

Genesis pays for scheduled maintenance on the G90 for 2 years and 26000 miles longer than Porsche pays for maintenance for the Panamera (3/36,000 vs. 1/10,000).

There are over 57 percent more Genesis dealers than there are Porsche dealers, which makes it much easier should you ever need service under the G90’s warranty.

Reliability

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Genesis vehicles are better in initial quality than Porsche vehicles. J.D. Power ranks Genesis fourth in initial quality, above the industry average. With 44 more problems per 100 vehicles, Porsche is ranked 24th, below the industry average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the statistics that show that Genesis vehicles are more reliable than Porsche vehicles. J.D. Power ranks Genesis fourth in reliability, above the industry average. With 7 more problems per 100 vehicles, Porsche is ranked 7th.

Fuel Economy and Range

On the EPA test cycle the G90 gets better mileage than the Panamera Sedan running its gasoline engine:

			MPG
G90
	AWD	3.5 turbo V6	18 city/26 hwy
		3.5 turbo/supercharged V6 Hybrid	17 city/24 hwy
Panamera Sedan
	RWD	2.9 turbo V6	18 city/24 hwy
	AWD	Turbo S 4.0 turbo V8	15 city/21 hwy
		2.9 turbo V6	18 city/24 hwy
		2.9 turbo V6	18 city/24 hwy
		4.0 turbo V8 Hybrid	18 city/22 hwy
		Executive 2.9 turbo V6	17 city/23 hwy
		Executive 2.9 turbo V6	17 city/23 hwy

To lower fuel costs and make buying fuel easier, the Genesis G90 uses regular unleaded gasoline (premium recommended for maximum performance). The Panamera requires premium, which can cost 20 to 55 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Genesis G90 higher (5 out of 10) than the Porsche Panamera (3 to 5). This means the G90 produces up to 16.5 pounds less smog-producing pollutants than the Panamera every 15,000 miles.

Brakes and Stopping

For better stopping power the G90’s standard brake rotors are larger than those on the Panamera:

	G90	Panamera
Front Rotors	14.2 inches	13.8 inches
Rear Rotors	13.6 inches	13 inches

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The G90 has a standard Brake Assistant System to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Panamera doesn’t offer a brake assist feature.

Tires and Wheels

For better ride, handling and brake cooling the G90 3.5T has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Panamera.

The G90 3.5T has a standard space-saver spare (not available on 3.5T e-SC) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Panamera; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

For a smoother ride and more stable handling, the G90’s wheelbase is 9.1 inches longer than on the Panamera (125.2 inches vs. 116.1 inches). The G90’s wheelbase is 3.2 inches longer than on the Panamera Executive (125.2 inches vs. 122 inches).

The G90’s front to rear weight distribution is more even (50.6% to 49.4%) than the Panamera’s (52% to 48%). This gives the G90 more stable handling and braking.

For better maneuverability, the G90 3.5T’s turning circle is .3 feet tighter than the Panamera’s (37.1 feet vs. 37.4 feet).

Chassis

The design of the Genesis G90 amounts to more than styling. The G90 has an aerodynamic coefficient of drag of .27 Cd. That is lower than the Panamera (.29 to .35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the G90 get better fuel mileage.

Passenger Space

The G90 has 13.2 cubic feet more passenger volume than the Panamera (109.2 vs. 96).

The G90 has 1.4 inches more front headroom, .4 inches more front legroom, 1 inch more front shoulder room, 2.2 inches more rear legroom and 3.6 inches more rear shoulder room than the Panamera.

Cargo Capacity

With its sedan body style and remote trunk release lockout, the G90 offers cargo security. The Panamera’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

Ergonomics

The G90 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Panamera doesn’t offer a remote starting system.

The G90’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Panamera.

On a hot day the G90’s driver can lower all the windows from a distance using the keyless remote. The driver of the Panamera can only operate the windows from inside the vehicle, with the ignition on.

The G90’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Panamera’s cruise control switches are unlit, making them difficult to find at night and operate safely.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the G90 has standard extendable sun visors. The Panamera doesn’t offer extendable visors.

The G90 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 costs extra on the Panamera.

The G90’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 Panamera doesn’t offer an automated parking system.
