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 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.

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

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).

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.
