For enhanced safety, the front and rear seat shoulder belts of the Genesis G90 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 CTS doesn’t offer pretensioners for the rear seat belts.

The G90 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 CTS doesn’t offer a whiplash protection system.

The G90’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 CTS doesn’t offer a driver alert monitor.

Both the G90 and the CTS 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 and available all wheel drive.

The Genesis G90 weighs 614 to 1253 pounds more than the Cadillac CTS. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Genesis G90 is safer than the CTS:

For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard 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 G90 its highest rating: “Top Pick Plus” for 2018, a rating granted to only 28 vehicles tested by the IIHS. The CTS was not even a standard “Top Pick” for 2018.


The G90 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The CTS’ 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Genesis’ powertrain warranty covers the G90 4 years and 30,000 miles longer than Cadillac covers the CTS. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the CTS ends after only 6 years or 70,000 miles.

The G90’s corrosion warranty is 1 year longer than the CTS’ (7 vs. 6 years).


To reliably start during all conditions and help handle large electrical loads, the G90 has a standard 950-amp battery. The CTS’ 730-amp battery isn’t as powerful.

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 G90’s reliability 15 points higher than the CTS.

J.D. Power and Associates rated the G90 first among large premium cars in their 2018 Initial Quality Study. The CTS 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 G90 3.3T RWD gets better fuel mileage than the CTS V-Sport (17 city/24 hwy vs. 16 city/24 hwy).

To lower fuel costs and make buying fuel easier, the Genesis G90 uses regular unleaded gasoline (premium recommended for maximum performance). The CTS V-Sport requires premium, which can cost 20 to 55 cents more per gallon.

The G90 has 2.9 gallons more fuel capacity than the CTS (21.9 vs. 19 gallons), for longer range between fill-ups.

Brakes and Stopping

For better stopping power the G90’s brake rotors are larger than those on the CTS:

Tires and Wheels

For better traction and acceleration, the G90 has larger rear tires than the CTS (275/40R19 vs. 245/45R17). The G90’s rear tires are larger than the largest rear tires available on the CTS (275/40R19 vs. 255/35R19).

The G90’s 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the CTS’ standard 45 series tires.

For better ride, handling and brake cooling the G90 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the CTS.

The G90 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 CTS; 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

For a smoother ride and more stable handling, the G90’s wheelbase is 9.8 inches longer than on the CTS (124.4 inches vs. 114.6 inches).

For better handling and stability, the track (width between the wheels) on the G90 is 3.1 inches wider in the front and 2.5 inches wider in the rear than the average track on the CTS.

The G90 3.3T AWD handles at .85 G’s, while the CTS Luxury AWD pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The G90 3.3T AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the CTS Luxury AWD (26.1 seconds @ .72 average G’s vs. 26.8 seconds @ .65 average G’s).


The design of the Genesis G90 amounts to more than styling. The G90 has an aerodynamic coefficient of drag of .27 Cd. That is lower than the CTS (.3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the G90 get better fuel mileage.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the G90 a Large car, while the CTS is rated a Mid-size.

The G90 has 16.2 cubic feet more passenger volume than the CTS (113.2 vs. 97).

The G90 has .7 inches more front headroom, .6 inches more front legroom, 2.7 inches more front hip room, 2.2 inches more front shoulder room, .5 inches more rear headroom, 2.4 inches more rear legroom, 1.7 inches more rear hip room and 3.1 inches more rear shoulder room than the CTS.

For enhanced passenger comfort on long trips the G90 5.0’s rear seats recline. The CTS’ rear seats don’t recline.

Cargo Capacity

The G90 has a much larger trunk than the CTS (15.7 vs. 13.7 cubic feet).

A low lift-over trunk design makes loading and unloading the G90 easier. The G90’s trunk lift-over height is 28.3 inches, while the CTS’ liftover is 29.5 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 G90’s power trunk, leaving your hands completely free. The G90’s power trunk can also be opened or closed by pressing a button. The CTS doesn’t offer a power or hands-free opening trunk.


Unlike the driver-only memory system in the CTS, the G90 has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The G90’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 CTS’ standard 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 G90’s available headlights were rated “Acceptable” by the IIHS, while the CTS’ headlights are rated “Poor.”

The G90 has standard front air-conditioned seats and the G90 5.0 also has them in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The CTS doesn’t offer air-conditioned seats in the rear.

The G90 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the CTS.


Consumer Reports® recommends the Genesis G90, based on reliability, safety and performance. The Cadillac CTS isn't recommended.
