Compare the2026 Cadillac OptiqVS 2026 BMW iX

For enhanced safety, the front seat shoulder belts of the Cadillac Optiq are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW iX doesn’t offer height-adjustable seat belts.

The Optiq 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 iX doesn’t offer front seat center airbags.

To deliver safety and visibility under dusty conditions the Cadillac Optiq’s backup monitor has a standard rear washer to keep the view clear. A camera washer system is only offered on some models of the BMW iX.

Both the Optiq and the iX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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 driver alert monitors.

Cadillac’s powertrain warranty covers the Optiq 2 years and 20,000 miles longer than BMW covers the iX. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the iX ends after only 4 years or 50,000 miles.

There are over 62 percent more Cadillac dealers than there are BMW dealers, which makes it much easier should you ever need service under the Optiq’s warranty.

J.D. Power and Associates’ 2025 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than BMW vehicles. J.D. Power ranks Cadillac above average in long-term dependability. With 33 more problems per 100 vehicles in the first three years of ownership, BMW is rated lower.

On the EPA test cycle the Optiq gets better mileage than the iX:

For better stopping power the Optiq-V’s front brake rotors are larger than those on the iX:

For better traction, the Optiq has larger standard tires than the iX (245/50R20 vs. 235/60R20).

The Optiq’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the iX xDrive45/60’s standard 60 series tires.

The Cadillac Optiq’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The BMW iX only has 5 wheel lugs per wheel.

Having a flat tire is dangerous, inconvenient and expensive. The self-sealing tires standard on the Optiq can automatically seal most punctures up to 3/16 of an inch, effectively preventing most flat tires. The iX doesn’t offer self-sealing tires.

For better maneuverability, the Optiq’s turning circle is 2.2 feet tighter than the iX’s (39.8 feet vs. 42 feet).

The Cadillac Optiq may be more efficient, handle and accelerate better because it weighs about 400 pounds less than the BMW iX.

The Optiq is 5.7 inches shorter than the iX, making the Optiq easier to handle, maneuver and park in tight spaces.

Unlike the driver-only memory system in the iX, the Optiq Premium/V-Series has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Optiq has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The iX doesn’t offer a house-current electrical outlet.

The Optiq is available in both rear-wheel drive and four-wheel drive configurations. The iX doesn’t offer a two-wheel drive configuration.
