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 Buick LaCrosse doesn’t offer pretensioners for the rear seat belts.

The G80’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The LaCrosse doesn’t offer pre-crash pretensioners.

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 LaCrosse doesn’t offer a whiplash protection system.

The G80’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The LaCrosse doesn’t offer a driver alert monitor.

Both the G80 and the LaCrosse 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, daytime running lights, rearview cameras, 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 LaCrosse was last qualified as only a “Top Pick” in 2017.


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 LaCrosse’s 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 Buick covers the LaCrosse. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the LaCrosse ends after only 6 years or 70,000 miles.

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

Genesis pays for scheduled maintenance on the G80 for 1 year and 12000 miles longer than Buick pays for maintenance for the LaCrosse (3/36,000 vs. 2/24,000).


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 G80’s reliability 43 points higher than the LaCrosse.

J.D. Power and Associates rated the G80 second among midsize premium cars in their 2018 Initial Quality Study. The LaCrosse 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 Buick vehicles. J.D. Power ranks Genesis first in initial quality, above the industry average. With 27 more problems per 100 vehicles, Buick is ranked 16th, below the industry average.

Tires and Wheels

For better traction, the G80 has larger standard tires than the LaCrosse (245/45R18 vs. 235/50R18).

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 LaCrosse’s standard 50 series tires. The G80’s optional 275/35R19 rear tires have a lower 35 series profile than the LaCrosse Essence/Premium/Avenir’s optional 40 series tires.

Suspension and Handling

For a smoother ride and more stable handling, the G80’s wheelbase is 4.1 inches longer than on the LaCrosse (118.5 inches vs. 114.4 inches).

For better handling and stability, the average track (width between the wheels) on the G80 is 1 inch wider in the front and 1.7 inches wider in the rear than the track on the LaCrosse.

The G80 5.0 handles at .88 G’s, while the LaCrosse Premium pulls only .84 G’s of cornering force in a Motor Trend skidpad test.

The G80 3.8 AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the LaCrosse Premium (26.2 seconds @ .69 average G’s vs. 26.8 seconds @ .66 average G’s).

For better maneuverability, the G80’s turning circle is 1.8 feet tighter than the LaCrosse’s (36.2 feet vs. 38 feet). The G80’s turning circle is .6 feet tighter than the LaCrosse’s (37.4 feet vs. 38 feet).

Passenger Space

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

The G80 has 5.7 cubic feet more passenger volume than the LaCrosse (107.7 vs. 102).

The G80 has 2.7 inches more front headroom, 3.7 inches more front legroom, .9 inches more front hip room, .6 inches more front shoulder room, 1 inch more rear headroom and .5 inches more rear shoulder room than the LaCrosse.

Cargo Capacity

The G80 has a larger trunk than the LaCrosse (15.3 vs. 15 cubic feet).

To allow full utilization of available cargo room, the G80’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. Its intrusive beam hinge reduces the LaCrosse’s useful trunk space.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the G80. The LaCrosse doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier when your hands are full, just waiting momentarily behind the back bumper can open the G80’s trunk, leaving your hands completely free. The G80 also offers an optional power trunk, which opens and closes automatically by pressing a button. The LaCrosse doesn’t offer a power or hands-free opening trunk.

Servicing Ease

The engine in the G80 is mounted longitudinally (North-South), instead of sideways, as in the LaCrosse. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.


The G80’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The LaCrosse’s rear power window switches have to be held the entire time to close them fully.

The Proximity Key standard on the G80 allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Buick LaCrosse’s Keyless Access doesn’t unlock the trunk.

The G80 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The LaCrosse doesn’t offer a locking fuel door.

The G80’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The LaCrosse’s manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The G80’s standard headlights were rated “Acceptable” by the IIHS, while the LaCrosse’s headlights are rated “Poor.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The G80 3.8 AWD offers available headlight washers to keep headlight output high. The LaCrosse doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors standard on the G80 detect other vehicles which could be blinded and automatically switch to low beams. The LaCrosse doesn’t offer automatic dimming high beams.

The G80 has standard heated front seats. Heated front seats are only available on the LaCrosse Sport Touring/Essence/Premium/Avenir. The G80 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the LaCrosse.

Economic Advantages

Insurance will cost less for the G80 owner. The Car Book by Jack Gillis rates the G80 with a number “” insurance rate while the LaCrosse is rated higher at a number “5” rate.

The G80 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the G80 will retain 40.26% to 44.12% of its original price after five years, while the LaCrosse only retains 23.54% to 40.34%.
