The Optiq is Cadillac’s most affordable electric SUV, and it’s already winning over drivers from other brands. Cadillac claims the new entry-level Optiq EV has “segment-best” rear cargo space, but how does it compare to other popular electric SUVs?

Cadillac has become the “luxury EV leader” in the US, according to GM’s CEO Mary Barra. However, that doesn’t include Tesla, apparently due to its “pricing structure,” a company spokesperson clarified.

In the second quarter, Cadillac was the leading luxury electric vehicle brand by market share and ranked fifth overall.

Cadillac’s surging presence in the luxury EV space is thanks to its growing lineup of electric SUVs. The company now offers an electric model in every segment, including the entry-level Optiq, midsize Lyriq, three-row Vistiq, and even bigger Escalade IQ and IQL.

According to Barra, nearly 80% of Optiq buyers are new to the brand. The low starting price of under $55,000, over 300 miles of driving range, and tech-heavy interior are big draws. However, the Cadillac Optiq also delivers several “segment-best” features, including rear cargo space.

How much space does the Optiq really have? To see how it stacks up, Edmunds put it to the test. GM says the 2025 Cadillac Optiq has segment-leading 26 cubic feet of rear cargo space.

The Optiq is smaller than the Lyriq, which has 28 cu ft. It offers about the same amount of space as the Chevy Equinox and Blazer EVs and other electric SUVs priced similarly.

Compared to the Hyundai IONIQ 5, Edmunds said the Optiq offers a more functional rear luggage space thanks to its open design.

Like other GM’s other electric SUVs, the Optiq offers an underfloor storage space. However, it is the smallest one in the group.

Although the Optiq “seems to be the worst,” among GM’s other electric SUVs, Edmunds added, it was “only a teensy bit so compared to the Equinox and Blazer EVs.” The Lyriq, on the other hand, offered considerably more space, as expected from a bigger, more premium EV.

Compared to luxury rivals, it offers much more space than the Audi Q4 E-tron, but significantly less than the Mercedes-Benz EQB. It’s closer to that of the Hyundai IONIQ 6 or Kia EV6.

The 2025 Cadillac Optiq starts at $54,390 and offers up to 302 miles of driving range. At 190″ in length, 75″ in width, and 65″ in height, the Cadillac Optiq is about the same size as the Tesla Model Y (187″ in length x 76″ in width x 64″ in height).

Cadillac is currently offering Optiq leases as low as $439 per month for 24 months for those with a competitive luxury brand vehicle.

Like most deals, this one will end at the end of September, which is when the $7,500 federal EV tax credit is also set to expire.
