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.

But, at "only" around 18.6 feet long, there's definitely room for the Cadillac Escalade IQ to grow. Or so says Cadillac, which is why the new Escalade IQL exists. At 19 feet long, those extra inches will carry more cargo and provide further passenger space for the already coddled occupants.

Cadillac is launching a more spacious version of its largest electric SUV, which gains legroom and cargo space without sacrificing range.
