Compare the2025 BMW 8 Series Gran CoupeVS 2024 Genesis G90

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 G90 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 G90 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.

Both the 8 Series Gran Coupe and the G90 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 G90’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 G90 3.5T e-SC 3.5 turbo/supercharged V6 hybrid:

On the EPA test cycle the 8 Series Gran Coupe gets better mileage than the G90:

Regenerative brakes improve the 8 Series Gran Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. The G90 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 G90:

The 8 Series Gran Coupe stops shorter than the G90:

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 G90 3.5T’s standard 45 series front and 40 series rear 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 G90 3.5T e-SC’s 40 series front and 35 series rear tires.

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 G90 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 G90 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 G90.

The 840i Gran Coupe xDrive handles at .92 G’s, while the G90 3.5T e-SC pulls only .83 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 G90 3.5T e-SC (25.1 seconds @ .74 average G’s vs. 26.2 seconds @ .68 average G’s).

The BMW 8 Series Gran Coupe may be more efficient, handle and accelerate better because it weighs about 300 to 650 pounds less than the Genesis G90.

The 8 Series Gran Coupe is 7.4 inches shorter than the G90, making the 8 Series Gran Coupe easier to handle, maneuver and park in tight spaces.

The front grille of the 8 Series Gran Coupe uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The G90 doesn’t offer active grille shutters.

The 8 Series Gran Coupe has a much larger trunk than the G90 (15.5 vs. 12 cubic feet).

The 8 Series Gran Coupe’s standard rear seats fold to accommodate long and bulky cargo. The G90 doesn’t offer folding rear seats, only a ski pass-through.

A Condition-Based Service Display is standard on the 8 Series Gran Coupe to save the owner time and money by calculating maintenance intervals for oil changes and vehicle inspections based on actual driving conditions. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Genesis doesn’t offer a maintenance reminder on the G90.

If the windows are left open on the 8 Series Gran Coupe the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the G90 can only close the windows from inside the vehicle, with the ignition on.

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 G90’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 G90 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.

The BMW 8 Series comes in coupe, convertible and sedan bodystyles; the Genesis G90 isn’t available as a coupe or convertible.

The 8 Series Gran Coupe is available in both rear-wheel drive and all-wheel drive configurations. The G90 doesn’t offer a two-wheel drive configuration.
