Compare the2023 Lexus LSVS 2023 Genesis G90

The Lexus LS has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The G90 doesn’t offer a front passenger side knee airbag.

The LS has standard Secondary Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G90 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.

Both the LS 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, driver alert monitors, available all wheel drive and around view monitors.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Lexus vehicles are more reliable than Genesis vehicles. Consumer Reports ranks Lexus third in overall reliability. Genesis is ranked fifth.

The LS 500’s standard 3.4 turbo V6 produces 7 more horsepower (416 vs. 409) and 37 lbs.-ft. more torque (442 vs. 405) than the G90 3.5T e-SC’s standard 3.5 turbo/supercharged V6 hybrid.

On the EPA test cycle the LS gets better mileage than the G90:

The LS can travel with zero emissions on a full charge for .6 miles. The G90 can’t move without running its internal combustion engine.

Regenerative brakes improve the LS 500h’s fuel efficiency by converting inertia back into energy instead of wasting it. The G90 doesn’t offer a regenerative braking system.

The LS’ standard fuel tank has 2.4 gallons more fuel capacity than the G90 (21.7 vs. 19.3 gallons), for longer range between fill-ups. The LS Hybrid’s standard fuel tank has 2.9 gallons more fuel capacity than the G90 (22.2 vs. 19.3 gallons).

A 10-speed automatic is standard on the Lexus LS, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the G90.

The LS 500h has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The G90 doesn’t offer a CVT.

For better stopping power the LS 500 F Sport’s front brake rotors are larger than those on the G90:

The LS stops much shorter than the G90:

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the LS can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The G90 doesn’t offer run-flat tires.

The LS F-Sport offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The G90 doesn’t offer an active sway bar system.

The LS 500 handles at .88 G’s, while the G90 3.5T e-SC pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the LS’ turning circle is .3 feet tighter than the G90 3.5T e-SC’s (36.8 feet vs. 37.1 feet). The LS AWD’s turning circle is .7 feet tighter than the G90 3.5T’s (39.4 feet vs. 40.1 feet).

The LS has a much larger trunk than the G90 (17 vs. 12 cubic feet).

A maintenance reminder system is standard on the LS to save the owner time and money by calculating maintenance intervals for oil changes, spark plug replacement, air filter replacement, tire rotation, radiator flush, brake pad replacement and transmission fluid replacement based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Genesis doesn’t offer a maintenance reminder on the G90.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Genesis. J.D. Power ranks Lexus first in service department satisfaction. With a 61% lower rating, Genesis is ranked 23rd.

If the windows are left open on the LS 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 close 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 LS offers available headlight washers to keep headlight output high. The G90 doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the LS has standard cornering lights to illuminate around corners when the turn signals are activated. The G90 doesn’t offer cornering lights. The LS also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The LS is available in both rear-wheel drive and all-wheel drive configurations. The G90 doesn’t offer a two-wheel drive configuration.

The Lexus LS outsold the Genesis G90 by 80% during the 2022 model year.
