Compare the2024 BMW 8 Series Gran CoupeVS 2023 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 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.

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.

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.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Genesis. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 30% lower rating, Genesis is ranked 23rd.
