Both the CTS and G80 have child safety locks to prevent children from opening the rear doors. The CTS has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The G80’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

Over 200 people are killed each year when backed over by motor vehicles. The CTS offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The G80 doesn’t offer backup collision prevention brakes.

The CTS Premium/V-Sport has a standard Surround Vision to allow the driver to see objects all around the vehicle on a screen. The G80 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Compared to metal, the CTS’ plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Genesis G80 has a metal gas tank.

Both the CTS and the G80 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.

There are almost 3 times as many Cadillac dealers as there are Genesis dealers, which makes it much easier should you ever need service under the CTS’ warranty.


The CTS V-Sport’s 3.6 turbo V6 produces 47 lbs.-ft. more torque (430 vs. 383) than the G80 5.0’s optional 5.0 DOHC V8.

An engine control system that can shut down half of the engine’s cylinders helps improve the CTS non-turbo V6’s fuel efficiency. The G80 doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the CTS (except V-Sport)’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The G80 doesn’t offer an automatic engine start/stop system.

The CTS has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The G80 doesn’t offer a cap-less fueling system.

Brakes and Stopping

The CTS’ standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the G80 3.8 are solid, not vented.

The CTS stops much shorter than the G80:

Tires and Wheels

For better traction, the CTS’ optional tires are larger than the largest tires available on the G80 (255/35R19 vs. 245/40R19).

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

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the CTS can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The G80 doesn’t offer run-flat tires.

Suspension and Handling

The CTS V-Sport handles at .97 G’s, while the G80 AWD pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

The CTS V-Sport goes through AutoWeek’s slalom 1.7 MPH faster than the G80 3.8 AWD (44.8 vs. 43.1 MPH).

The CTS V-Sport executes Motor Trend’s “Figure Eight” maneuver 2.2 seconds quicker than the G80 5.0 (24.5 seconds @ .78 average G’s vs. 26.7 seconds @ .7 average G’s).


The Cadillac CTS may be more efficient, handle and accelerate better because it weighs about 550 to 700 pounds less than the Genesis G80.

The front grille of the CTS (except V-Sport or Driver Assist Package) uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The G80 doesn’t offer active grille shutters.

The CTS uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The G80 doesn’t offer active noise cancellation.

As tested by Car and Driver while cruising at 70 MPH, the interior of the CTS V-Sport is quieter than the G80 5.0 (66 vs. 70 dB).

Cargo Capacity

The CTS’ optional rear seats fold to accommodate long and bulky cargo. The G80 doesn’t offer folding rear seats, only a ski pass-through.


The CTS V6 offers up to a 1000 lbs. towing capacity. The G80 has no towing capacity.


The CTS’ standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the G80.

On a hot day the CTS’ driver can lower all the windows from a distance using the keyless remote. The driver of the G80 can only operate the windows from inside the vehicle, with the ignition on.

Consumer Reports rated the CTS’ headlight performance “Fair,” a higher rating than the G80’s headlights, which were rated “Poor.”

Optional air conditioned seats in the CTS keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The G80 only offers an air-conditioned driver’s seat.

The CTS offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The G80 doesn’t offer a house-current electrical outlet.

The CTS Premium/V-Sport’s Automatic Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The G80 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the CTS owner. The Complete Car Cost Guide estimates that insurance for the CTS will cost $925 less than the G80 over a five-year period.


The CTS V-Sport was chosen as one of Car and Driver’s “Top Ten” for 6 of the last 12 years. The G80 has never been a Car and Driver “Top Ten” pick.

Motor Trend selected the CTS as their 2014 Car of the Year. The G80 has never been chosen.

The CTS was chosen as one of Automobile Magazine’s “All Stars” in 2014. The G80 has never been an “All Star.”

The Cadillac CTS outsold the Genesis G80 by 46% during 2018.
