Compare the2025 Genesis G80VS 2025 Porsche Panamera

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 Panamera doesn’t offer a back seat reminder.

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 Panamera 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 Panamera doesn’t offer a whiplash protection system.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Genesis G80 achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Porsche Panamera has not been tested.

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

Both the G80 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors 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 Panamera has not yet been evaluated by the IIHS for 2024.

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 Panamera’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Genesis’ powertrain warranty covers the G80 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 G80 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 21 percent more Genesis dealers than there are Porsche dealers, which makes it easier should you ever need service under the G80’s warranty.

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

On the EPA test cycle the G80 gets better mileage than the Panamera running its gasoline engine:

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 Panamera; it requires you to depend on roadside assistance and your vehicle will have to be towed.

For a smoother ride and more stable handling, the G80’s wheelbase is 2.4 inches longer than on the Panamera (118.5 inches vs. 116.1 inches).

For better maneuverability, the G80’s turning circle is .9 feet tighter than the Panamera’s (38.1 feet vs. 39 feet).

The front grille of the G80 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Panamera doesn’t offer active grille shutters.

The G80 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.

If the windows are left open on the G80 the driver can close them all from a distance using the remote. The driver of the Panamera can only operate the windows from inside the vehicle, with the ignition on.

The G80’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 G80 has standard extendable sun visors. The Panamera doesn’t offer extendable visors.
