Compare the2025 Genesis G90VS 2025 Cadillac CT5

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 CT5 doesn’t offer pretensioners for its rear seat belts.

The G90’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CT5 doesn’t offer pre-crash pretensioners.

Both the G90 and CT5 have child safety locks to prevent children from opening the rear doors. The G90 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 CT5’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.

The G90 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The CT5 doesn’t offer front seat center airbags.

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 CT5 doesn’t offer a whiplash protection system.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the G90. But it costs extra on the CT5.

Both the G90 and the CT5 have standard driver and passenger frontal airbags, front 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.

The CT5 has not yet been evaluated by the IIHS for 2024.

For better stopping power the G90’s brake rotors are larger than those on the CT5:

The G90’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 CT5 are solid, not vented.

For better traction and acceleration, the G90 has larger rear tires than the CT5 (275/40R20 vs. 245/45R18). The G90 3.5T’s rear tires are larger than the largest rear tires available on the CT5 (275/40R20 vs. 255/35R20).

The G90 3.5T’s standard 275/40R20 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the CT5’s standard 45 series tires.

For better ride, handling and brake cooling the G90 3.5T has standard 20-inch wheels. Smaller 18-inch wheels are standard on the CT5. The G90 3.5T e-SC’s 21-inch wheels are larger than the 20-inch wheels optional on the CT5.

The G90 3.5T has a standard space-saver spare (not available on 3.5T e-SC) so you can replace a flat tire and drive to have the flat repaired or replaced.

If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

For better maneuverability, the G90 3.5T e-SC’s turning circle is 1.9 feet tighter than the CT5’s (37.1 feet vs. 39 feet). The G90 3.5T’s turning circle is .6 feet tighter than the CT5 AWD’s (40.1 feet vs. 40.7 feet).

The G90 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The CT5 doesn’t offer active noise cancellation.

Because it has more passenger and cargo room, the EPA rates the G90 a Large car, while the CT5 is rated a Mid-size.

The G90 has 10.2 cubic feet more passenger volume than the CT5 (109.2 vs. 99).

The G90 has .4 inches more front headroom, 2.8 inches more front hip room, 2.4 inches more front shoulder room, 1.4 inches more rear headroom, 1.3 inches more rear hip room and 2.2 inches more rear shoulder room than the CT5.

For enhanced passenger comfort on long trips the G90 3.5T e-SC’s rear seats recline. The CT5’s rear seats don’t recline.

With its sedan body style, valet key and remote trunk release lockout, the G90 offers cargo security. The CT5’s non-lockable folding seat defeats cargo security.

To make loading and unloading groceries and cargo easier, especially for short adults, the G90 has a standard power trunk, which opens and closes automatically by pressing a button or just by waiting momentarily behind the back bumper, completely leaving your hands free. The CT5 doesn’t offer a power trunk.

Unlike the driver-only memory system in the CT5, 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 3.5T e-SC’s power side swing out doors make it much easier to load and unload kids and cargo. One touch opens the door, before you even get to the car. The CT5 doesn’t offer a power rear door.

The Genesis G90 has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors costs extra on the CT5.

Both the G90 and the CT5 have standard heated front seats. The G90 also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the CT5.

The G90 has standard front air conditioned seats and the G90 3.5T e-SC also has them in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The CT5 doesn’t offer air-conditioned seats in the rear.

Both the G90 and the CT5 have standard massaging front seats. The G90 3.5T e-SC also has standard massaging rear seats in order to maximize comfort and eliminate fatigue on long trips. Massaging rear seats aren’t available in the CT5.

Both the Genesis G90 and the Cadillac CT5 have a standard Qi wireless phone charging system in the front seat. To easily keep personal devices charged in the rear seat, without cables tangling and wearing out, the G90 3.5T e-SC also has a standard wireless charging system.

The G90’s Smart Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The CT5’s automatic parking system does not offer parking by remote control.
