The best Cadillacs have always been big ― inside and out. The IQ maintains that. Its wheelbase is 2 inches longer than the extended-wheelbase of the ESV version of the internal combustion Escalade, and overall length is more than a foot greater than the regular wheelbase model. (An even bigger IQL model goes on shortly as a 2026 model.)

It also weighs approximately 9000 pounds, owing to its all-electric powertrain and a massive (there's that word again) lithium-ion battery with 205.0 kWh of usable energy. That's enough juice to power the Escalade IQ for a claimed 460 miles.
