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 Cadillac XTS 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 XTS doesn’t offer pre-crash pretensioners.

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 XTS doesn’t offer a driver alert monitor.

Both the G80 and the XTS 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 XTS has not been fully 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 XTS’ 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 Cadillac covers the XTS. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the XTS ends after only 6 years or 70,000 miles.

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


To reliably start during all conditions and help handle large electrical loads, the G80 has a standard 740-amp battery. The XTS’ 660-amp battery isn’t as powerful.

The battery on the G80 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the G80’s battery 20 to 30 degrees cooler, its life is increased by years. The XTS’ battery is in the hot engine compartment.

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 29 points higher than the XTS.

J.D. Power and Associates rated the G80 second among midsize premium cars in their 2018 Initial Quality Study. The XTS 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 Cadillac vehicles. J.D. Power ranks Genesis first in initial quality, above the industry average. With 22 more problems per 100 vehicles, Cadillac is ranked 12th.

Fuel Economy and Range

On the EPA test cycle the G80 3.3T Sport AWD gets better fuel mileage than the XTS V-Sport (17 city/24 hwy vs. 16 city/23 hwy).

To lower fuel costs and make buying fuel easier, the Genesis G80 uses regular unleaded gasoline (premium recommended on G80 3.3T Sport for maximum performance). The XTS V-Sport requires premium, which can cost 20 to 55 cents more per gallon.

The G80 has 1.3 gallons more fuel capacity than the XTS FWD’s standard fuel tank (20.3 vs. 19 gallons), for longer range between fill-ups.


An eight-speed automatic is standard on the Genesis G80, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the XTS.

Brakes and Stopping

For better stopping power the G80 3.3T Sport’s brake rotors are larger than those on the XTS:

Tires and Wheels

The G80’s optional 275/35R19 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the XTS’ optional 40 series tires.

Suspension and Handling

The G80 has standard front and rear stabilizer bars, which help keep the G80 flat and controlled during cornering. The XTS’ suspension doesn’t offer a rear stabilizer bar.

For a smoother ride and more stable handling, the G80’s wheelbase is 6.8 inches longer than on the XTS (118.5 inches vs. 111.7 inches).

For better handling and stability, the average track (width between the wheels) on the G80 is 2.2 inches wider in the front and 2.8 inches wider in the rear than the track on the XTS.

The G80 5.0 handles at .86 G’s, while the XTS AWD pulls only .79 G’s of cornering force in a Car and Driver skidpad test.

The G80 3.8 AWD executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the XTS AWD (26.2 seconds @ .69 average G’s vs. 27.6 seconds @ .63 average G’s).

For better maneuverability, the G80’s turning circle is 2.5 feet tighter than the XTS’ (36.2 feet vs. 38.7 feet). The G80’s turning circle is 1.3 feet tighter than the XTS’ (37.4 feet vs. 38.7 feet).


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

Passenger Space

The G80 has 3.5 cubic feet more passenger volume than the XTS (107.7 vs. 104.2).

The G80 has 2.1 inches more front headroom, 3.6 inches more front legroom, .6 inches more front hip room, .4 inches more front shoulder room, .4 inches more rear headroom, .5 inches more rear hip room and .8 inches more rear shoulder room than the XTS.

Cargo Capacity

A low lift-over trunk design makes loading and unloading the G80 easier. The G80’s trunk lift-over height is 27.5 inches, while the XTS’ liftover is 30 inches.

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 XTS 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 XTS. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.


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 XTS 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 XTS’ standard manually variable intermittent wipers have to be constantly adjusted.

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 XTS doesn’t offer headlight washers.

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 XTS is rated higher at a number “8” 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 XTS only retains 34.07% to 36.66%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Genesis G80 will be $7194 to $9027 less than for the Cadillac XTS.


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