Compare the2023 Genesis G80VS 2023 BMW 4 Series Gran Coupe

For enhanced safety, the front and rear seat shoulder belts of the Genesis G80 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 4 Series Gran Coupe doesn’t offer pretensioners for its rear seat belts.

Both the G80 and 4 Series Gran Coupe have child safety locks to prevent children from opening the rear doors. The G80 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The 4 Series Gran Coupe’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the G80 are reminded to check the back seat if they opened the rear door before starting out. The 4 Series Gran Coupe doesn’t offer a back seat reminder.

The G80 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The 4 Series Gran Coupe doesn’t offer front seat center airbags.

The G80 has standard Anti-Whiplash Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash.

The 4 Series Gran Coupe doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The G80 Sport Prestige has standard Parking Collision-Avoidance Assist-Reverse that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The 4 Series Gran Coupe doesn’t offer backup collision prevention brakes.

The G80 Sport/Sport Prestige has a standard Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The 4 Series Gran Coupe 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.

Both the G80 and the 4 Series Gran Coupe 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 and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the G80 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 112 vehicles tested by the IIHS. The 4 Series Gran Coupe has not been tested, yet.

The G80 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the 4 Series Gran Coupe; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the 4 Series Gran Coupe don’t have a run-flat feature, either.

The design of the Genesis G80 amounts to more than styling. The G80 has an aerodynamic coefficient of drag of .27 Cd. That is lower than the 4 Series Gran Coupe (.28 to .3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the G80 get better fuel mileage.

The G80’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The 4 Series Gran Coupe doesn’t offer an easy entry system.

A power rear sunshade and manual rear side window sunshades are standard in the G80 Advanced/Sport/Sport Prestige to help block heat and glare for the rear passengers. The 4 Series Gran Coupe doesn’t offer a rear or rear side window sunshades.
