Compare the2025 BMW 8 Series Gran CoupeVS 2025 Genesis G80

The BMW 8 Series Gran Coupe has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The G80 doesn’t offer a front passenger side knee airbag.

The 8 Series Gran Coupe has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G80 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Compared to metal, the 8 Series Gran Coupe’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Genesis G80 has a metal gas tank.

Both the 8 Series Gran Coupe and the G80 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

The 8 Series Gran Coupe’s corrosion warranty is 5 years longer than the G80’s (12 vs. 7 years).

There are over 44 percent more BMW dealers than there are Genesis dealers, which makes it easier should you ever need service under the 8 Series Gran Coupe’s warranty.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Genesis With 10 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks BMW higher than Genesis.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that BMW vehicles are more reliable than Genesis vehicles. Consumer Reports ranks BMW 9 places higher in reliability than Genesis.

As tested in Motor Trend the 840i Gran Coupe 3.0 turbo 6-cylinder is faster than the Genesis G80:

On the EPA test cycle the 8 Series Gran Coupe gets better mileage than the G80:

Regenerative brakes improve the 8 Series Gran Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. The G80 doesn’t offer a regenerative braking system.

For better stopping power the 8 Series Gran Coupe’s brake rotors are larger than those on the G80:

The 8 Series Gran Coupe’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the G80 2.5T are solid, not vented.

The 8 Series Gran Coupe stops much shorter than the G80:

For better traction and acceleration, the 8 Series Gran Coupe has larger standard rear tires than the G80 (275/35R19 vs. 245/50R18). The Alpina B8 Gran Coupe’s rear tires are larger than the largest rear tires available on the G80 (285/30R21 vs. 275/40R19).

The 840i Gran Coupe’s standard 245/40R19 front and 275/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the G80 2.5T Standard’s standard 50 series tires. The 8 Series Gran Coupe’s optional 245/35R20 front and 275/30R20 rear tires have a lower 35 series front and 30 series rear profile than the G80 Sport Prestige’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 840i Gran Coupe has standard 19-inch wheels. Smaller 18-inch wheels are standard on the G80 2.5T Standard. The Alpina B8 Gran Coupe’s 21-inch wheels are larger than the 20-inch wheels on the G80 Sport Prestige.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 8 Series Gran Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The G80 doesn’t offer run-flat tires.

The 8 Series Gran Coupe M550i/Alpina B8 has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The G80 doesn’t offer an active sway bar system.

The 8 Series Gran Coupe M550i/Alpina B8 offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Genesis doesn’t offer an active suspension on the G80.

The 840i Gran Coupe xDrive handles at .92 G’s, while the G80 pulls only .84 G’s of cornering force in a Motor Trend skidpad test.

The 840i Gran Coupe xDrive executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the G80 (25.1 seconds @ .74 average G’s vs. 26.2 seconds @ .68 average G’s).

The 8 Series Gran Coupe has a much larger trunk than the G80 (15.5 vs. 13.1 cubic feet).

The 8 Series Gran Coupe’s standard rear seats fold to accommodate long and bulky cargo. The G80 doesn’t offer folding rear seats, only a ski pass-through.

Unlike the driver-only memory system in the G80, the 8 Series Gran Coupe has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The 8 Series Gran Coupe’s standard Comfort Access allow you to unlock the doors from any outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Proximity Key standard on the G80 doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

Laser headlights, standard on the 8 Series Gran Coupe, produce their light by firing blue lasers through phosphorus, a process that uses one-half the power of the G80’s LED headlights. Laser headlights can have double the range of LEDs with a much smaller surface area.

To help drivers avoid possible obstacles, the 8 Series Gran Coupe has standard cornering lights to illuminate around corners when the turn signals are activated. The G80 doesn’t offer cornering lights. The 8 Series Gran Coupe also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW 8 Series has a standard wireless phone charging system (Qi) in the center console. Only the G80 Sport Prestige/3.5T offers wireless charging.
