Safety Comparison

The 7 Series has standard Post-Crash Braking, which automatically apply 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.

Over 200 people are killed each year when backed over by motor vehicles. The 7 Series offers an optional backup collision prevention system which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The G90 doesn’t offer backup collision prevention brakes.

An active infrared night vision system optional on the 7 Series helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then projects the image on the windshield, near the driver’s line of sight. The G90 doesn’t offer a night vision system.

Both the 7 Series 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, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty Comparison

The 7 Series’ corrosion warranty is 5 years longer than the G90’s (12 vs. 7 years).

Fuel Economy and Range Comparison

On the EPA test cycle the 740e running on electricity gets better fuel mileage than the G90 3.3T AWD (62 city/68 hwy MPGe vs. 17 city/24 hwy).

On the EPA test cycle the 740e running its gasoline engine gets better fuel mileage than the G90 3.3T AWD (25 city/29 hwy vs. 17 city/24 hwy).

The 740e can drive on battery power alone for up to 14 miles. The G90 must run its internal combustion engine to move.

Regenerative brakes improve the 7 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. The G90 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 7 Series’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The G90 doesn’t offer an automatic engine start/stop system.

Brakes and Stopping Comparison

For better stopping power the 750i’s brake rotors are larger than those on the G90:

Tires and Wheels Comparison

For better traction, the Alpina B7’s optional tires are larger than the largest tires available on the G90 (F:255/35R21 & R:295/30R21 vs. F:245/45R19 & R:275/40R19).

The Alpina B7’s optional 255/35R21 front and 295/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the G90’s 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the Alpina B7 offers optional 21-inch wheels. The G90’s largest wheels are only 19-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 7 Series 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.

Suspension and Handling Comparison

The 7 Series offers 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 front and rear suspension of the 7 Series uses air springs for a smoother, controlled ride than the G90, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The 7 Series 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 7 Series has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The 7 Series’ height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The G90 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the 7 Series’ wheelbase is 2 inches longer than on the G90 (126.4 inches vs. 124.4 inches).

The Alpina B7 handles at .97 G’s, while the G90 5.0 pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The 750i xDrive executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the G90 3.3T AWD (25.4 seconds @ .75 average G’s vs. 26.9 seconds @ .67 average G’s).

Chassis Comparison

The BMW 7 Series may be more efficient, handle and accelerate better because it weighs up to about 450 pounds less than the Genesis G90.

The front grille of the 7 Series 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.

Passenger Space Comparison

The 7 Series has .1 inches more front shoulder room, .9 inches more rear headroom and 6.6 inches more rear legroom than the G90.

Cargo Capacity Comparison

A low lift-over trunk design makes loading and unloading the 7 Series easier. The 7 Series’ trunk lift-over height is 27.2 inches, while the G90’s liftover is 28.3 inches.

Ergonomics Comparison

If the windows are left down on the 7 Series the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the G90 can only operate the windows from inside the vehicle, with the ignition on.

The 7 Series’ optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The G90 doesn’t offer an automated parking system.

Recommendations Comparison

The BMW 7 Series outsold the Genesis G90 (Equus) by over six to one during 2016.
