Safety

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the CT6 are reminded to check the back seat if they opened the rear door before starting out. The G80 doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The CT6 Premium Luxury/Platinum/Sport has standard 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.

An active infrared night vision system optional on the CT6 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The G80 doesn’t offer a night vision system.

The CT6 Premium Luxury/Platinum/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 CT6’s 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 CT6 and the G80 have standard driver and passenger frontal airbags, front 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 crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.

Warranty

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 CT6’s warranty.

An engine control system that can shut down half of the engine’s cylinders helps improve the CT6 V6/V8’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 CT6’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 CT6 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.

Transmission

A 10-speed automatic is standard on the Cadillac CT6, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the G80.

Brakes and Stopping

The CT6’s 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 CT6 stops much shorter than the G80:

Tires and Wheels

For better ride, handling and brake cooling the CT6 offers optional 20-inch wheels. The G80’s largest wheels are only 19-inches.

Suspension and Handling

For a smoother ride and more stable handling, the CT6’s wheelbase is 3.9 inches longer than on the G80 (122.4 inches vs. 118.5 inches).

The CT6 AWD handles at .86 G’s, while the G80 AWD pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

The CT6 AWD executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the G80 5.0 (25.4 seconds @ .75 average G’s vs. 26.7 seconds @ .7 average G’s).

Chassis

The Cadillac CT6 may be more efficient, handle and accelerate better because it weighs about 300 to 500 pounds less than the Genesis G80.

The front grille of the CT6 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 CT6 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 CT6 is quieter than the G80 5.0 (66 vs. 70 dB).

Passenger Space

The CT6 has 13.5 cubic feet more passenger volume than the G80 (121.2 vs. 107.7).

The CT6 has .7 inches more front legroom, .2 inches more front hip room and 5.4 inches more rear legroom than the G80.

For enhanced passenger comfort on long trips the CT6’s available rear seats recline. The G80’s rear seats don’t recline.

Cargo Capacity

The CT6 has a larger trunk than the G80 (15.8 vs. 15.3 cubic feet).

Towing

The CT6 has a 1000 lbs. towing capacity. The G80 has no towing capacity.

Ergonomics

Unlike the driver-only memory system in the G80, the CT6 Premium Luxury/Platinum/Sport has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, suspension setting, outside mirror angle and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The CT6’s 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.

The CT6’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The G80 does not have an oil pressure gauge.

On a hot day the CT6’s 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.

Optional air conditioned front and rear seats keep the CT6’s passengers comfortable and take the sting out of hot leather in summer. The G80 only offers an air-conditioned driver’s seat.

The CT6 Luxury/Premium/Platinum has a 115-volt a/c outlet, 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 CT6 Premium Luxury/Platinum/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.

Recommendations

The Cadillac CT6 outsold the Genesis G80 by 26% during 2018.
