For enhanced safety, the front and rear seat shoulder belts of the Lexus GS Series 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 Genesis G80 doesn’t offer pretensioners for the rear seat belts.

An active infrared night vision system optional on the GS 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 displays the image on a monitor in the dashboard. The G80 doesn’t offer a night vision system.

Both the GS Series and the G80 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, height-adjustable front shoulder belts, 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, rear parking sensors and rear cross-path warning.

The GS 350 handles at .94 G’s, while the G80 3.8 AWD pulls only .86 G’s of cornering force in a Motor Trend skidpad test.

The GS 350 executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the G80 5.0 (25.4 seconds @ .71 average G’s vs. 26.7 seconds @ .7 average G’s).

The Lexus GS Series may be more efficient, handle and accelerate better because it weighs about 450 to 850 pounds less than the Genesis G80.

The GS Series is 4.4 inches shorter than the G80, making the GS Series easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver, the interior of the GS 350 is quieter than the G80 5.0:

Unlike the driver-only memory system in the G80, the GS Series offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GS Series’ instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The G80 does not have an oil pressure gauge.

If the windows are left open on the GS Series the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Lexus service department.) The driver of the G80 can only operate the windows from inside the vehicle, with the ignition on.

Consumer Reports rated the GS Series’ headlight performance “Good,” a higher rating than the G80’s headlights, which were rated “Poor.”

Optional air conditioned seats in the GS Series 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.
