Cadillac applies the Escalade name to a new all-electric full-size SUV, sitting above the Cadillac Optiq EV.

Cadillac’s biggest electric vehicle yet arrives with little direction competition. The new 2025 Cadillac Escalade IQ is unrelated to the internal-combustion Escalade full-size SUV, instead sharing underpinnings with the GMC Hummer EV and electric full-size pickup trucks from General Motors. That leaves an electric luxury SUV unrivaled in size, for now.

Verdict: The Escalade IQ does things no other full-size SUV can, but it’s still hard to justify.
