Safety

The 5 Series Sedan 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 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.

A passive infrared night vision system optional on the 5 Series Sedan helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The G80 doesn’t offer a night vision system.

The 5 Series Sedan offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The G80 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Compared to metal, the 5 Series Sedan’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 5 Series Sedan and the G80 have standard driver and passenger frontal airbags, front side-impact 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available all wheel drive.

Warranty

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

Reliability

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that BMW vehicles are more reliable than Genesis vehicles. Consumer Reports ranks BMW 4 places higher in reliability than Genesis.

Regenerative brakes improve the 5 Series Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The G80 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 5 Series Sedan’s 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 G80 doesn’t offer an automatic engine start/stop system.

Transmission

The 5 Series Sedan’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The G80 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the M550i’s brake rotors are larger than those on the G80:

The 5 Series Sedan’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 3.8 are solid, not vented.

The 5 Series Sedan stops much shorter than the G80:

Tires and Wheels

The 5 Series Sedan’s optional 245/35R20 front and 275/30R20 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 G80’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 5 Series Sedan offers optional 20-inch wheels. The G80’s largest wheels are only 19-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 5 Series Sedan 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.

Suspension and Handling

The M550i xDrive handles at .92 G’s, while the G80 3.8 AWD pulls only .86 G’s of cornering force in a Motor Trend skidpad test.

The M550i xDrive executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the G80 5.0 (24.9 seconds @ .77 average G’s vs. 26.7 seconds @ .7 average G’s).

Chassis

The BMW 5 Series Sedan may be more efficient, handle and accelerate better because it weighs about 350 to 400 pounds less than the Genesis G80.

The front grille of the 5 Series Sedan uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The G80 doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the 540i is quieter than the G80 5.0:

At idle

38 dB

39 dB

70 MPH Cruising

Passenger Space

The 5 Series Sedan has .4 inches more front shoulder room and 1.5 inches more rear legroom than the G80.

Cargo Capacity

The 5 Series Sedan has a much larger trunk than the G80 (18.7 vs. 15.3 cubic feet).

A low lift-over trunk design makes loading and unloading the 5 Series Sedan easier. The 5 Series Sedan’s trunk lift-over height is 26.2 inches, while the G80’s liftover is 27.5 inches.

The 5 Series Sedan’s standard rear seats fold to accommodate long and bulky cargo. The G80 doesn’t offer folding rear seats, only a ski pass-through.

Ergonomics

Unlike the driver-only memory system in the G80, the 5 Series Sedan offers an optional 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 5 Series Sedan’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the G80.

If the windows are left open on the 5 Series Sedan 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 also lower the windows the same way. The driver of the G80 can only operate the windows from inside the vehicle, with the ignition on.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The 5 Series Sedan’s available headlights were rated “Good” by the IIHS, while the G80’s headlights are rated “Acceptable” to .”

Optional air conditioned seats in the 5 Series Sedan keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The G80 only offers an air-conditioned driver’s seat.

The 5 Series Sedan’s 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 G80 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the 5 Series Sedan owner. The Complete Car Cost Guide estimates that insurance for the 5 Series Sedan will cost $355 less than the G80 over a five-year period.

Recommendations

Consumer Reports® recommends both the BMW 5 Series Sedan and the Genesis G80, based on reliability, safety and performance.

The BMW 5 Series outsold the Genesis G80 by almost six to one during 2018.
