Safety

For enhanced safety, the front shoulder belts of the Lexus GS Series are height-adjustable, and the rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Genesis G90 has only front height-adjustable 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 G90 doesn’t offer a night vision system.

Both the GS Series and the G90 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and rear parking sensors.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the GS Series’ reliability 30 points higher than the G90.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Lexus vehicles are more reliable than Genesis vehicles. Consumer Reports ranks Lexus first in reliability. Genesis is ranked 12th.

Tires and Wheels

The GS Series F Sport’s 235/40R19 front and 265/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the G90’s 45 series front and 40 series rear tires.

Suspension and Handling

The GS 350 handles at .94 G’s, while the G90 3.3T AWD pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The GS 350 executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the G90 3.3T AWD (25.4 seconds @ .71 average G’s vs. 26.9 seconds @ .67 average G’s).

For better maneuverability, the GS Series’ turning circle is 4.4 feet tighter than the G90’s (34.8 feet vs. 39.2 feet). The GS Series AWD’s turning circle is 3.8 feet tighter than the G90’s (35.4 feet vs. 39.2 feet).

Chassis

The Lexus GS Series may be more efficient, handle and accelerate better because it weighs about 900 to 1000 pounds less than the Genesis G90.

The GS Series is 1 foot shorter than the G90, making the GS Series easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The GS Series has a much larger trunk than the G90 (18.4 vs. 15.7 cubic feet).

Ergonomics

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 G90 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 G90 can only operate the windows from inside the vehicle, with the ignition on.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The GS Series offers available headlight washers to keep headlight output high. The G90 doesn’t offer headlight washers.

Recommendations

Consumer Reports® recommends the Lexus GS Series, based on reliability, safety and performance.

The Lexus GS Series outsold the Genesis G90 by over two to one during the 2018 model year.
