For enhanced safety, the front and rear seat shoulder belts of the Genesis G80 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Lexus LS Series has only front height-adjustable seat belts.

The G80 has standard Anti-Whiplash Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Anti-Whiplash Front Head Restraints system moves the headrests forward to prevent neck and spine injuries. The LS Series doesn’t offer a whiplash protection system.

Both the G80 and the LS Series have standard driver and passenger frontal airbags, front 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 rear parking sensors.

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, with its optional front crash prevention system, its “Good” rating in the new passenger-side small overlap crash test, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the G80 its highest rating: “Top Pick Plus” for 2018, a rating granted to only 28 vehicles tested by the IIHS. The LS Series has not been tested, yet.


The G80 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The LS Series’ 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G80 4 years and 30,000 miles longer than Lexus covers the LS Series. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the LS Series ends after only 6 years or 70,000 miles.

The G80’s corrosion warranty is 1 year longer than the LS Series’ (7 vs. 6 years).

Genesis pays for scheduled maintenance on the G80 for 3 years and 36,000 miles. Genesis will pay for oil changes, lubrication and any other required maintenance. Lexus only pays for the first scheduled maintenance visit on the LS Series.

There are over 47 percent more Genesis dealers than there are Lexus dealers, which makes it easier should you ever need service under the G80’s warranty.


J.D. Power and Associates rated the G80 second among midsize premium cars in their 2018 Initial Quality Study. The LS Series isn’t in the top three in its category.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Genesis vehicles are better in initial quality than Lexus vehicles. J.D. Power ranks Genesis first in initial quality, above the industry average. With 16 more problems per 100 vehicles, Lexus is ranked 8th.

Tires and Wheels

The G80 3.8’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the LS Series’ standard 50 series tires. The G80’s optional 245/40R19 front and 275/35R19 rear tires have a lower 40 series front and 35 series rear profile than the LS Series F Sport’s 45 series front and 40 series rear tires.

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 LS Series; 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.

Suspension and Handling

The G80 5.0 handles at .88 G’s, while the LS 500 AWD pulls only .85 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the G80’s turning circle is .6 feet tighter than the LS Series’ (36.2 feet vs. 36.8 feet). The G80’s turning circle is 2 feet tighter than the LS Series AWD’s (37.4 feet vs. 39.4 feet).


The Genesis G80 may be more efficient, handle and accelerate better because it weighs about 400 to 500 pounds less than the Lexus LS Series.

The G80 is 9.6 inches shorter than the LS Series, making the G80 easier to handle, maneuver and park in tight spaces.

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 LS Series (.27 to .3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the G80 get better fuel mileage.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the G80 a Large car, while the LS Series is rated a Mid-size.

The G80 has 8.3 cubic feet more passenger volume than the LS Series (107.7 vs. 99.4).

The G80 has 3.8 inches more front headroom, 4.7 inches more front legroom, .2 inches more front hip room, .9 inches more rear headroom and .7 inches more rear shoulder room than the LS Series.


Consumer Reports® recommends the Genesis G80, based on reliability, safety and performance. The Lexus LS Series isn't recommended.

The Genesis G80 outsold the Lexus LS Series by 47% during the 2018 model year.
