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 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CT6. But it costs extra on the G80.

An active infrared night vision system standard on the CT6 Premium Luxury/Platinum 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.

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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

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.

On the EPA test cycle the CT6 V6 gets better fuel mileage than the G80 3.8 AWD (18 city/27 hwy vs. 18 city/24 hwy).

An engine control system that can shut down some of the engine’s cylinders helps improve the CT6’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.

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.

13.6 inches

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.

For better ride, handling and brake cooling the CT6 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the G80 3.8. The CT6 Premium Luxury/Platinum’s 20-inch wheels are larger than the 19-inch wheels optional on the G80.

The CT6 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The G80 doesn’t offer vehicle monitored tire inflation.

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.

Unlike the driver-only memory system in the G80, the CT6 Premium Luxury/Platinum 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 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.

The CT6 Premium Luxury/Platinum has standard front air conditioned seats and the CT6 Platinum also has them in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The G80 only offers an air-conditioned driver’s seat.

The CT6 Platinum has standard massaging front and rear seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the G80.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Cadillac CT6 has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the G80.

The CT6 Premium Luxury/Platinum’s Automatic Park Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The G80 doesn’t offer an automated parking system.
