Compare the2027 Cadillac Optiq VS 2027 Rivian R2

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 Optiq are reminded to check the back seat if they opened the rear door before starting out. The R2 doesn’t offer a back seat reminder.

The Cadillac Optiq has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The R2 doesn’t offer knee airbags.

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 R2 doesn’t offer front seat center airbags.

The Optiq has standard Post-Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The R2 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The Optiq has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The R2 doesn’t offer backup collision prevention brakes.

The Cadillac Optiq’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Rivian R2 does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.

Both the Optiq and R2 have rear cross-traffic warning, but the Optiq has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The R2’s Rear Cross-Traffic Warning doesn’t automatically brake.

Both the Optiq and the R2 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear 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, around view monitors, rear cross-path warning and driver alert monitors.

There are almost 6 times as many Cadillac dealers as there are Rivian dealers, which makes it much easier should you ever need service under the Optiq’s warranty.

J.D. Power and Associates’ 2025 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Rivian vehicles. With 74 fewer problems per 100 vehicles, JD Power ranks Cadillac higher than Rivian.

From surveys of all its subscribers, Consumer Reports’ March 2026 Auto Issue reports that Cadillac vehicles are more reliable than Rivian vehicles. Consumer Reports ranks Cadillac 8 places higher in reliability than Rivian.

The Optiq-V’s optional electric motors produces 41 lbs.-ft. more torque (650 vs. 609) than the R2 Performance’s optional electric motors.

For better stopping power the Optiq-V’s front brake rotors are larger than those on the R2:

	Optiq-V	R2
Front Rotors	15.4 inches	13.8 inches
Rear Rotors	13.6 inches	13.2 inches

For better traction, the Optiq’s optional tires are larger than the largest tires available on the R2 (275/40R21 vs. 255/55R21).

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 R2 Standard’s standard 65 series tires. The Optiq’s optional tires have a lower 40 series profile than the R2 Premium’s 55 series tires.

For better ride, handling and brake cooling the Optiq has standard 20-inch wheels. Smaller 19-inch wheels are standard on the R2 Standard.

The Cadillac Optiq’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Rivian R2 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 R2 doesn’t offer self-sealing tires.

For excellent aerodynamics, the Optiq has standard flush composite headlights. The R2 has recessed headlights that spoil its aerodynamic shape and create extra drag.

To make loading groceries and cargo easier when your hands are full, the Optiq’s liftgate can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The R2 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Unlike the driver-only memory system in the R2, 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 Premium/V-Series has a standard heads-up display that projects speed, navigation instruction and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The R2 doesn’t offer a heads-up display.

If the windows are left open on the Optiq the driver can close all of them from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the R2 can only operate the windows from inside the vehicle, with the ignition on.

The Optiq’s standard Keyless Access allows you to unlock the doors from any outside door handle, open the cargo door, and start the vehicle, all without removing the key from pocket or purse. An advanced key system standard on the R2 doesn’t offer a sensor on any door except the driver’s, so you’ll have to walk to the driver's door to touch the handle.

The Optiq has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the R2.

The Optiq is equipped with both FM and AM stereo radios, offering access too more content and better coverage than the R2, which solely provides FM radio. With AM radio, you can enjoy a wider variety of stations featuring news, talk shows, sports commentary, native language programing, automated traffic guidance, and emergency broadcasts. AM waves travel further and penetrate buildings and obstacles more effectively than FM signals, especially at night. Having both FM and AM stereo radios the Optiq offers a more comprehensive listening experience compared to only FM in the R2.

HD Radio boasts several benefits over conventional radio: superior sound quality with clearer and consistent FM broadcasts, CD-quality audio, and Multicast Channels offering up to four streams from a single station, adding programming choices. Cars like the Optiq equipped with available HD Radio provide an improved in-car entertainment experience. The R2, devoid of this technology, foregoes these benefits. Selecting the Cadillac Optiq empowers drivers to enjoy a more immersive and enjoyable listening experience while on the go.

The Optiq’s Enhanced Automatic Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Enhanced Automatic Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The R2 doesn’t offer an automated parking system.
