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 G90 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 G90 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 G90 doesn’t offer a night vision system.

Both the CT6 and the G90 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, around view monitors 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 G90 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 G90 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 G90 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 G90.

Brakes and Stopping

The CT6 stops much shorter than the G90:

Motor Trend

Tires and Wheels

The CT6’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the G90’s 45 series front tires.

For better ride, handling and brake cooling the CT6 offers optional 20-inch wheels. The G90’s largest wheels are only 19-inches.

Suspension and Handling

The CT6 AWD handles at .88 G’s, while the G90 3.3T AWD pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The CT6 AWD executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the G90 3.3T AWD (25.4 seconds @ .75 average G’s vs. 26.9 seconds @ .67 average G’s).

Chassis

The Cadillac CT6 may be more efficient, handle and accelerate better because it weighs about 500 to 900 pounds less than the Genesis G90.

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 G90 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 G90 doesn’t offer active noise cancellation.

Passenger Space

The CT6 has 8 cubic feet more passenger volume than the G90 (121.2 vs. 113.2).

The CT6 has .1 inches more front legroom and 2.6 inches more rear legroom than the G90.

Ergonomics

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 G90 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 G90 can only operate the windows from inside the vehicle, with the ignition on.

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 G90 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 G90 doesn’t offer an automated parking system.

Recommendations

The Cadillac CT6 outsold the Genesis G90 by over four to one during 2018.
