Cadillac Escalade IQL is officially GM's biggest SUV, taking the title in multiple dimensions. See how the new 2026 Cadillac Escalade IQL stacks up.

The big SUV is a step in fulfilling Cadillac's vision for an all-electric lineup of "tier one" luxury vehicles.

Elsewhere, other Escalade IQ specs apply to the IQL: a 12.2 cubic-foot front boot (big enough for golf clubs), the 24in standard wheels clad in 35in tyres, the Air Ride adaptive suspension and that 55in curved dash display.
