Safety

For enhanced safety, the front and rear seat shoulder belts of the Genesis G90 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW 7 Series doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Genesis G90 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 7 Series doesn’t offer height-adjustable seat belts.

Both the G90 and the 7 Series have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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 all wheel drive.

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the G90 its highest rating: “Top Pick Plus” for 2018, a rating granted to only 28 vehicles tested by the IIHS. The 7 Series has not been tested, yet.

Warranty

The G90 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The 7 Series’ 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G90 6 years and 50,000 miles longer than BMW covers the 7 Series. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the 7 Series ends after only 4 years or 50,000 miles.

Reliability

The battery on the G90 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the G90’s battery 20 to 30 degrees cooler, its life is increased by years. The 7 Series’ battery is in the hot engine compartment.

J.D. Power and Associates rated the G90 first among large premium cars in their 2018 Initial Quality Study. The 7 Series was rated second.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Genesis vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Genesis first in initial quality, above the industry average. With 19 more problems per 100 vehicles, BMW is ranked 11th.

Tires and Wheels

For better traction and acceleration, the G90 has larger rear tires than the 7 Series (275/40R19 vs. 245/50R18).

The G90’s 245/45R19 front and 275/40R19 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the 7 Series’ standard 50 series tires.

For better ride, handling and brake cooling the G90 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 7 Series.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the G90 is 1.1 inches wider in the front than on the 7 Series.

For better maneuverability, the G90’s turning circle is 2.8 feet tighter than the 740i’s (39.2 feet vs. 42 feet). The G90’s turning circle is 3.1 feet tighter than the 750i’s (39.2 feet vs. 42.3 feet).

Passenger Space

The G90 has 1.2 inches more front headroom, 4.9 inches more front legroom and .2 inches more rear shoulder room than the 7 Series.

The front step up height for the G90 is 2.7 inches lower than the 7 Series (14” vs. 16.7”). The G90’s rear step up height is 2.5 inches lower than the 7 Series’ (14.2” vs. 16.7”).

Cargo Capacity

The G90 has a much larger trunk than the 7 Series (15.7 vs. 14 cubic feet).

Ergonomics

The G90 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the 7 Series.
